Micro-credit applications as a struggle against women poverty: a case study of Isparta province, Turkey
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Icoz, Esra
The micro-credit applications used as a struggle against women poverty in Isparta province were examined in this study. The main material of the study was comprised of original data acquired via face to face interviews with 212 women micro-credit users in the city of Isparta. It was determined based on the study results that 62.26% of the women micro-credit users were between the ages of 30-49, 54.25% had low education levels (primary school), 87.74% were married with an average family size of 3.76 people. It was observed that 87.26% of the women had social security and that the monthly family income of 40.09% varied between 1001-1500 TL. Majority of the women (58.49%) indicated that they used the micro-credit for developing their already existing businesses. It was set forth that the women used the micro-credit mostly in areas of commerce (43.87%), handwork/embroidery (28.30%) and animal husbandry (19.34%). The women indicated that their social relations and self-confidence increased as a result of the credit. About 80% of the women stated that there was a little increase in their family income after the micro-credit and it was determined that majority of the women (89.62%) want to use micro-credit again. Of the women who participated in the study 68.40% suggested an increase in the amount of credit while 51.89% suggested longer payment periods between two installments.

The benchmarking of agricultural production and labor in agriculture in the European plan
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Lupu, Geanina-Valentina
In this paper we propose a comparative analysis on European agricultural production and labor involved in this activity. Rural areas have a vital social role and a significant growth potential in society. There is a diminishing in reserves of manpower in rural areas throughout the EU, especially in emergent countries. The existing projections at this time, show a growing demand for agricultural products. For those who work in this field it is essential to be able to plan and predict medium and long-term activity. In this respect, we analyze the statistics of people working in some of the EU countries to have an overview of employment in the agricultural sector. The purpose of this paper is to investigate the evolution of the two factors that influence the agriculture and the macroeconomic stability. With the increase in the share of industry and services in the economy, agriculture begins to be increasingly less attractive and available a large number of jobs in this sector. In this respect, an important role returns to farmers in sustainable economic development, diversification of the rural economy by creating new jobs and protecting the environment. But farmers by themselves without a concrete and immediate help from the authorities cannot succeed in reducing this alarming phenomenon. In conclusion, agriculture is an important contribution to the EU GDP and has a fluctuating and uneven route across the European Union in terms of reporting the value of agricultural production to the number of farms, their size and manpower involved.

Tourists’ motivations and preferences for agritourism activities
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Moraru, Radu-Adrian
The agritourism is a category of tourism in full expansion worldwide. By its social and economic contribution to the development of rural communities and farms, the agritourism became an attractive alternative for the diversification of agricultural businesses. The main aim of the present paper is to identify, based on the international literature of concern, which are the reasons that determine the tourists to choose agritourism as a form of leisure. The studies carried out by specialists in different countries point out that the tourists’ preference for agritourism is highly influenced by the context in which they are, and is generated by a wide range of “push” and “pull” type of factors. The tourists have different expectations from a stay at the agritourism farm due to a large variety of motivations. According to their nature, the reasons to practice agritourism are physical, emotional, cultural and personal, being subject to status or desire for self-development. The physical and mental relaxation, the opportunity to spend nice time together with the family or friends, the possibility to buy fresh fruits and vegetables and the wish to have direct contact with nature and to enjoy the beauty of landscapes are the most obvious motives that determine the tourists to attempt an agritourism experience. The participation at agricultural activities does not represented a major interest for agritourists. The relationships between the tourists’ preferences for agritourism activities and their motivations show that they are interested in those activities that are consistent with the initial reasons sustaining their decision to practice agritourism.

Functional model for determining the optimal duration of use of fixed assets
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Bodescu, Dan; Dumitrachi, Dragos-Nicolae; Moraru, Radu-Adrian; Galeș, Daniel-Costel
The purpose of this paper was to present a functional model for determining the duration of use of fixed assets based on the relationship between the average fixed cost of depreciation of the fixed medium and the opportunity cost determined by the market of the respective product. The objectives of the paper included: 1. determining the correlation between the duration of use, the total distance travelled and the price of fixed assets; 2. determining the optimal duration of use of the fixed assets based on the relationship between the average fixed cost and the opportunity cost. In order to determine the optimal duration of use, the minimum marginal cost of depreciation was calculated as the ratio of the difference between the prices between moments n and n + 1 and the length or kilometres travelled in the range n and n + 1. Also, the marginal opportunity cost for the remaining transport capacity to be used was determined starting from the hypothesis that the market assigns a price to a usable capacity and to a capacity too old to be used, the price is nil. As a result, we identified the average price for the maximum duration or distance of use. The marginal opportunity cost was determined as the ratio between the price at one point and the remaining difference to be used by kilometres or old. The remaining difference to be used was calculated as the difference between the maximum duration that can be used and the time at time i or the maximum distance travelled and the distance travelled at price i. The average cost with the depreciation of the fixed means analysed is determined by the distance travelled and its age. The proposed model allows to determine an optimal duration of use of the fixed means according to their age and the transport distance. This model can be easily adapted to other types of fixed assets and the quality of the results is given by the existence of a significant number of data on their selling prices.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Demircan, Vecdi; Demir, Suzan; Dalgic, Asli
In this study, it was aimed to determine fast food consumption and the factors affecting this consumption for Isparta University of Applied Sciences students. The main material of the study consisted of the data obtained from surveys, which were conducted by face-to-face interviews with 384 students. Result showed that 89.06% of the students consumed fast food and 10.94% did not. The average monthly income of students was 1412.26 TL and the share of expenditure on fast food products in the monthly income was 21.25%. It was determined that students consumed steak tartar ala turca (85.96%) among the fast food products, followed by French fries (83.63%) and hamburger (82.75%). It was found that 42.69% of the students consumed fast food products in dinner. It was determined that the most important reasons for fast food consumption were being economical (38.60%) and fast (30.70%). The relationship between the age of the students (p <0.10), the number of individuals in the family (p <0.10) and their opinion about healthy-eating (p <0.01) and fast food consumption were found to be statistically significant.

The alcmaeon project: bringing humanities, the arts and medical education together
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Colibaba, Anca-Cristina; Gheorghiu, Irina; Constantinescu, Richard; Croitoru, Irina; Petraru, Alina
The article is a systematic reflection on the Alcmaeon European project (2018-ES01-KA203-050606), which puts forth an alternative model for integrating the history of medicine into medical education. The project is developed within a partnership between education organizations, museums and universities from Spain, Great Britain, Italy, Greece and Romania. The project aims at shifting the focus of teaching the history of medicine from simply chronicling events to examining the process of medical development over time and studying it as a continuous inquiry by providing medical professionals with structured and harmonized online materials available in its own virtual museum and library. In addition, the arts can be used as a means to educate students of medicine in an agreeable atmosphere by means of focused interpretation and discussion with a view to developing their professionalism, selfawareness and communication skills, increasingly important assets for physicians. Bringing these disciplines together enables students to form deeper connections with patients and develop empathy and creativity. Overall, the focus group analysis highlighted that integrating the history of medicine into medical education is necessary as it gives students insights into past procedures and achievements, raises their awareness about the importance of medical and social ethics, provides lessons in medical education, empathy, charity work, community involvement, ethical standards, and laboratory research.

Study on European financing in the field of public food and tourism, at the level of Romania
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Creangă, Diana-Elena; Ștefan, Gavril; Coca, Oana
Europe is today the culmination of its development, and European funding is the driving force behind the development of the economy of the Member States. The study aims to break down the economic phenomena related to the absorption of European funds and to analyze their evolution in the Multiannual Financial Frameworks (MFFs) 2007-2013 and 2014-2020. Methodologically, the research included a documentary analysis of some studies, reports, strategic documents and an empirical study based on the sociological investigation in the field of public food and tourism. The paper analyzed the impact of European funding at the level of Romania and the added value of European funds in the field of public food and tourism. The results of the study highlighted the major impact of European financing on economic development and the increase of the competitiveness of the economic sectors. The MFF 2007 - 2013 contributed to a great extent to the achievement of the proposed objectives. Thus, 9.4 million jobs were created, of which 42,000 research jobs were created, 0.4 million SME-s were created, access to road networks, railways, water supply increased for about 7 million people. In the current programming period (2014-2020) the European Commission aims to support specific areas such as economic, social and territorial cohesion, competitiveness for growth and jobs, administration, global Europe, sustainable growth; natural resources, security, and citizenship. For the next programming period, 2021 - 2027, the proposed budget amounts to 1.135 billion euros, representing the equivalent of 1.11% of the gross national income of the EU-27. The long-term objectives of the European Union are related to the single market, innovation and the digital sector, cohesion and values, natural resources and environment, migration and border management, security and defense, neighborhood and worldwide, European public administration. The case study conducted in the field of public food and tourism has revealed that although there are still barriers to accessing European funds (legislative, strict conditions imposed by specific guidelines, financial limitations) there is a high openness to the added value brought to the national economy by European funding.

Assesment of the integration mode of the sustainable development in European rural area and North-Est region
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Ciuștea Butnaru, Mintenica-Mariana; Brezuleanu, Stejărel
Within the rural development, the agriculture of Romania holds an important weight, detaching itself by the contribution to the realization of the gross domestic product, as well as by about 29% of the employed population, returning 0.43 ha / inhabitant, compared to 0.21 ha / inhabitant in European Union. This explains why agriculture is a very attractive and profitable branch. In this context, the strategy of sustainable rural development and the increase of the performance and the competitiveness of the agricultural production at national, regional or local level, must start from the economic-financial analysis of the situation of the agricultural sector, according to which to proceed to the adoption of those measures that lead, firstly, to the increase of agricultural production and, secondly, to its efficiency by attracting European funds. The paper aims to identify the way of approaching sustainable development within the regional development strategies, having as a case study the North-East Region, and to evaluate the implementation of the strategic objectives, at regional level and in the rural environment. The main objectives come to meet the goal set by: the conceptual delimitation of sustainable development in a global, European and national context; assessing the dimension of the sustainable development phenomenon at global, European and national level; assessing the inter-correlation between the regional strategic objectives and the sustainable development objectives for the North-East Region (2007-2013 and 2014-2020); the projection of the evolution of the result indicators of the regional strategy for the period 2007-2020 (with target indicators for 2022), which highlights the contribution to ensuring regional and rural sustainable development, compared to the evolutionary trend from 2000-2013 and 2014-2020; identifying strategic proposals for ensuring regional and rural sustainable development.

Innovative methods in the teaching process: the boomerang model
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Velescu, Elena
The starting point of this research is chapter 2.3. "Models for lesson planning" from the volume Deutsch Lehren Lernen 6 (Ende K., Grotjahn R., Kleppin K., Mohr I., 2013). In this section it is a description of the teaching process, which Jeremy Harmer (2007) called the "boomerang model". Because I noticed the German language learners have difficulty in understanding and in acquiring language structures and grammatical rules, and because they were inhibited to express themselves in a foreign language and made many grammatical mistakes, I introduced this method in the course. According to this model, the teacher motivates the students in the initial phase; it arouses interest and establishes a task, such as the correct application of prepositions (where? / wo and wohin in German). The advantage of this method is the development of autonomy in the learning process, and the discovery of the grammatical rules, of the linguistic means, necessary for the accomplishment of the work tasks which is coming naturally.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Dragomir, Neculai; Sauer, Maria; Dragoș, Marcela; Sauer, Ioan; Pădeanu, Ioan; Voia, Octavian-Sorin; Vălușescu, Daniela
The sown meadows, consisting of complex mixtures of grassland grasses and legumes species ensure a high level of production, a high quality of feed, an important source of biological nitrogen, which ensures the protein autonomy of the forage system. The paper highlights the influence of the structure of some perennial grasses and legumes, sown in the plains area, on the production of plant dry matter, on the use of the sown grassland, on the conversion into animal products and on the economic efficiency of the pratoecosystem in relation to animals. Carried out studies have shown that sown grasslands, consisting of a complex mixture (Lolium perenne 30 % + Festuca pratensis 30 % + Trifolium repens 20 % + Lotus corniculatus 20 %), in the plains area, used for grazing with sheep, obtains, in average, about 9 t/ha feed dry matter, over 3200 l/ha milk production and very high milk quality (5.5 % protein and 8.0 % fat). The research results showed an increase of sheep’s milk production in complex mixtures in both years of experience, compared to the mixture variant consisting only of grass species. The value of the quality indices of sheep's milk is higher, both in protein and fat, in the grazed variant, sown with a complex mixture of grasses and legumes, compared to the variant sown with only a mixture of grass species. In livestock farms, the complex sown grassland, consisting of several species of grassland grasses and legumes (multispecies) secures and makes the fodder system more efficient, ensuring both the constant increase of the feed value of the fodder and the increase of the quality indices of the animal products.

Studies regarding the influence of some phenotypic parameters on raw material’s quality of different genotypes from Mentha genus
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Lungoci, Constantin; Vodă, Andreea-Daniela; Țibulcă Ghițău, Carmen-Simona; Jităreanu, Carmenica-Doina; Robu, Teodor
Peppermint (Mentha sp.) is one of the most cultivated medicinal plant worldwide due to its diverse range of products in which it can be used. The main natural product (Herba Menthae) is used in pharmaceutical industry, as an additive and flavor in food industry and the extracted essential oil is used in numerous cosmetic and selfcare products. This study’s purpose is to quantify a series of biometrical and physiological elements of some species which pertain to Mentha genus from USAMV’s “Collection of Medicinal Plants”, which influence the raw material’s quality and the quantity of essential oils. The studied mint species are Mentha viridis var. crispata (Schrod) Beck Ecotype 2, Mentha longifolia (L.) Hudson Ecotype 2, Mentha spicata var. viridis L., Mentha longifolia (L.) Hudson Ecotip 1, Mentha viridis var. crispata (Schrod) Beck Ecotype 1. The study followed the influence of the leaf surface, the content of chlorophyll pigments, but also the total leaf number on the production of volatile oil. Being a very important parameter in the reception and estimation of needed quantity of raw material, drying efficiency was determined for each cultivar. The highest amount of volatile oil was obtained from two ecotypes of the Mentha viridis var. crispata (Schrod) Beck species, in a percentage of 0.54% and 0.58%, and the lowest amount from Mentha longifolia (L.) Hudson Ecotype 2. The results are showing that the quantity of volatile oil is influenced by the leaf surface, especially by the basal leaves. It is being proved that the amount of the volatile oil is influenced by the leaf surface, its placement and the chlorophyll pigments content and the cultivar factor, in the same environmental conditions.

Assessment of the quality of secondary production from different agricultural crops used as primary material for densified solid biofuels
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Marian, Grigore; Țenu, Ioan; Roșca, Radu; Gudîma, Andrei; Pavlenco, Andrei
The quality of densified solid biofuels is directly influenced by the biomass characteristics used as feedstock. Under the conditions of the Republic of Moldova, the main source of raw material used in the production of briquettes and pellets is represented by agricultural residues and those from the food industry. For this reason, it is important to know the qualitative characteristics of these residues. The purpose of this study is to highlight the main qualitative parameters of agricultural residues used as energy sources specific for the Republic of Moldova. The issue of research refers to the estimation of the possibilities of using indigenous agricultural residues as a raw material for the production of densified solid biofuels with ENPlus 3 characteristics. The investigative methodology is based on a complex study, organized and realized in the Solid Biofuels Laboratory of the State Agrarian University of Moldova. The paper presents the results of the research regarding the estimation of the calorific value, the moisture content, the ash content and the chemical analysis of the main agricultural residues from the agrarian sector depending on their origin and specificity, emphasizing on herbaceous, arboreal and vines residues. The study showed that only about 10% of the residues from agricultural activities can be used directly to produce bio briquettes and pellets with qualitative indicators according to the requirements of ENPlus 3. It should be noted that practically, all agricultural and vineyard residues can be used as a raw material to the production of ENPlus certified densified solid biofuels, and herbaceous residues can only be used in mixtures with other types of vegetable biomass or require pre-treatment before densification, for example, by torrefaction.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Mihai, Doru; Sârbu, Nicoleta-Daniela; Mudura, Radu; Sasu, Andrei-Sebastian; Sasu Anghelusyan, Veronica; Ilinca, Liviu-Constantin
Precision agriculture represents a new branch developed due to the new technologies, which represents, for most farmers, a challenge in their use in order to obtain improved productions from year to year, and the conservation of the potential of agricultural lands. Determining the problems of agricultural crops, was done recently through field inspections, which requires a great deal of time. The emergence of drones, dedicated applications for using the results obtained with the help of drones and other new technologies, such as multi-spectral satellite imagery, opens a new perspective for farmers, which allows them to obtain better results in the field of crops but also the conservation of agricultural land. The use of drones and the applications dedicated to the processing of the data obtained with them, will allow to increase the efficiency of the farms and also to conserve the potential of agricultural lands. It will be possible to determine precisely the areas in which to intervene in case of drought / excess humidity, deficiency / excess of nutrients. Also, yeld maps can be made that will highlight the distribution and density of the plants on the surface, the number of berries / fruits, etc. Early detection of weeds, fungi and other pests in crops, to prevent their spread as well as various diseases. At present, more and more farmers are convinced of the efficiency of drone application and precision agriculture applications. In addition to these solutions, farmers also need machines dedicated to the application of the results obtained with these technologies (agricultural equipment equipped with GPS, sensors for various climatic and soil parameters, variable nozzles for seeders and fertilizers, motion / rotation sensors, counters, etc.).

Researches on the implementation of the forest cadastre using the GNSS technology and the remote sensing
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Agapie Mereuță, Ioana; Luca, Mihail; Gherasim, Paul-Marian
In Romania, about 27% of the land area is the forest fund. Sustainable development of forest involves their inventory and permanent updating in order to achieve a precise cadastral record. The land that are part of the forest cadastre are mainly represented by wooded land. The work consists in identifying and delimiting the cadastral area of a forest plot using modern ways of locating and tracking changes in time. The research aims to determine the modern aspects regarding cadastre and forest management issues, as well as how to create a database of the type of Geographic Information Systems, necessary in the context of the development of forest resources. In order to achieve the proposed objective, modern technologies for field measurements were used, such as high-precision Trimble GNSS systems, capable of providing a high degree of precision and productivity. Thanks to the built-in technology, GPS receivers, receives signals from all existing satellite constellations, ensuring a high quality of the measurements made. The studied area was also analyzed using satellite imagery which allowed the delimitation of forest boundaries through the digitization process. The use of very high resolution satellite imagery ensures high digitization accuracy, taking place in a shorter time than the terrestrial measurement method. Inventory of forests also involve the registration of plots in the Land Book. Through the ETERRA 3 application, the areas entered in the integrated national cadastre and land register can be viewed, interrogated and updated at all times. Since clearance is a major current problem, the most accurate and efficient cadastral survey and record keeping of forest enables sustainable forestry development in order to ensure a good quality of life.

Current situation of insects species which are affecting the plants in The Botanical Park of Timisoara
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Muntean, Ana-Covilca; Grozea, Ioana
The green spaces represent places of relaxation and release from the daily stress for many of the inhabitants of Timisoara but also from the other villages of the Timis county. The botanical park or botanical garden is one of the most visited green places, being located near the central historical area and also constituting an important didactic and scientific support. The plants that enter its composition are both herbaceous and arboreous. In the last 10 years since its rearrangement, a number of plants have been affected by insects, either indigenous or invasive. A current overview of the analyzed landscape shows that it has lost its aesthetic and scientific qualities, so that areas with healthy plants alternate with areas with affected plants (natural color change, appearance of sticky secretions and inadequate odors due to the attack of Hemiptera, premature maturation, etc.). For an efficient management of the monitoring activities, the park was divided into 5 sectors, in which, 10 observation points were established. Monthly, during May-September, 2019, readings were made at each observation point (identified with the help of GPS mobile). From our observations it was found that the following species of insects were present, at a medium and high population level: Metcalfa pruinosa, Nezara viridula, Cydalima perspectalis, Cameraria ohridella Tetranychus urticae, Eriophyes tiliae, Trialeurodes vaporariorum, Aphis gossypii and Eriosoma lanigerum. Also other species were observed, but at a lower level. We focused mainly on invasive species, which unfortunately were the most aggressive, in many cases their attack manifesting until the plant is compromised. This is the case of the species Metcalfa pruinosa (from Hemiptera) and Cydalyma perspectalis (from Lepidoptera) which have proved to be the most dangerous insect species for the plants in the botanical park.

Additions to the oribatid mites fauna (acari, sarcoptiformes, oribatida) and their community structure in the Danube Delta Biosphere Reserve
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Ivan, Otilia
The present study is part of some recent ecological investigations carried out in the Danube Delta Biosphere Reserve in order to assess the risks to biodiversity and the impact of natural and anthropogenic factors on characteristic ecosystems. Meadows and agro-ecosystems have been taken into study, aiming to investigate qualitatively and quantitatively the oribatid communities, diversity and distribution of species depending on the type of habitat. In terms of fauna 60 species have been identified belonging to 43 genera and 31 families of the suborder Oribatida Dugès, 1834. The family Ctenacaridae Grandjean, 1954, genera Ctenacarus Grandjean, 1939 Exochocepheus Woolley and Higgins, 1968, also the species Ctenacarus araneolus (Grandjean, 1932), Exochocepheus laticuspis (Balogh and Mahunka, 1965) and Oribatula (Zygoribatula) andrianovae (Bulanova-Zachvatkina, 1967) were recorded for the first time in Romanian fauna. The global average abundance and number of species varies widely from one sampling site to another, even in the case of similar ecosystems. However, in the non-grazing meadows, generally higher values of these parameters were observed compared to cultivated soils and pastures. From a qualitative point of view, notable differences were observed in the species composition of the oribatid communities in meadows and crops, even if they were located in the immediate vicinity. On the other hand, a degree of similarity was noted in the species composition and structure of oribatid coenoses in the agro-ecosystems, regardless of the type of crop and soil.

Study regarding the use of mulberry leaves (Kokuso 21 variety) by Bombyx mori (Triumf hybrid)
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Doliș, Marius-Gheorghe; Rațu, Roxana-Nicoleta
In order to assess how efficient is the use of Mulberry leaf by the Bombyx mori Triumf larvae hybrid, some determinations were made regarding the nutritional value and digestibility of the worm leaf administered as food (leaves from a Japanese variety, Kokuso 21), during a series of summer growth. The results showed that ongoing vegetation and growth process of this hybrid, the Mulberry leaves suffer an aging phenomenon, revealed by diminishing its chemical composition quality. According to this, most of the nutritional substances from Mulberry leaves, except cellulose, manifest a continuous decline during the growth period. The digestibility of these nutritional components registered a value of 55.4%, the raw energy value was 4216 kcal/kg dry substance, the digestive energy was 2156 kcal/kg (DS), while the metabolic energy was 1993-2010 kcal/kg (DS). The efficiency of converting ingestion into silk had a value of 10.1% and the digestion was 17.88%.

Preliminary results about experimental sunflower hybrids resistant to both sulfonylurea and imidazolinone herbicide
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Anton, Florin-Gabriel
It is important to choose what herbicide we want to use depending on degree of weed infestation and what type of sunflower hybrid resistant at sulfonylurea or imidizalinone herbicide. Some farmers who cultivated sunflower in SouthEast of Romania where broomrape is present with the most virulent races, use IMI sunflower hybrids and spray with a IMI herbicide for a better control. Other farmers, prefers SU sunflower hybrids especially in field without broomrape. At NARDI Fundulea, we created sunflower hybrids resistant at sulfonylurea herbicide and sunflower hybrids resistant at imidazolinone herbicide but also we created experimental sunflower hybrids resistant to booth sulfonylurea and imidazolinone herbicide. In year 2018, at NARDI Fundulea, we tested, four experimental sunflower hybrids SU-IMI Plus, H1 SU-IMI Plus, H2 SU-IMI Plus, H3 SU-IMI Plus and H4 SU-IMI Plus, for resistance at sulfonylurea herbicide in Express Sun™ system and imidazolinone herbicide in Clearfield® system. These four experimental sunflower hybrids were full resistant in booth systems, in Express Sun™ and Clearfield®.

The influence of treatments with different phytosanitary products (fungicides) on the attack of some phytopathogenic fungi and on Barley harvest – Salmandre variety - in 2018 pedoclimatic conditions of The Eastern Baragan
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Velichi, Eugen
Barley is attacked during the vegetation period by many pathogenic agents. One of these pathogenic agents, Pyrenophora graminea fungus producing the barley’s leaf stripe (Velichi E. 2012) appeared in the Eastern Baragan area in 2018. An experiment took place in 2018, where 4 products of phytosanitary usage were used, as follows: ACANTO PLUS (picoxistrobin 200g/l + cyproconazole 80 g/l), MYSTIC 250 EC (tebuconazole 250 g/l) and FALCON 460 EC (triadimenole 43 g/l + tebuconazole 167 g/l + spiroxamine 250 g/l). This experiment consisted in 7 variants (6 variants with phytosanitary treatments in different combinations of products, plus one control variant not treated). The experiment was placed in Latin square. The 7 variants were placed in 7 repetitions. Among the pathogenic agents monitored, the greatest attacks were produced by Pyrenphora graminea fungus, which produces the tearing of barley’s leaves. The first two leaves below the spike were analyzed for this. The observations showed that the degree of attack (D.A %) of the disease (barley’s leaf stripe) was more reduced at all 6 variants of treatment than that of the control variant, V7. The harvests of the treated variants (V1 … V6) were higher than the harvest of the untreated control variant, V7. The harvests of treatment variants were significantly higher than the harvest of the untreated control variant (statistical assurance, LD 5%), except for V1, where the harvest increment has no statistical assurance. In what concerns the economic efficiency, like in the study performed in the year 2016, the fungicide product MYSTIC 250 EC 0.5 l/ha has proved to be the most efficient from price point of view.

In Romania the knowledge of the main diseases and pests that occur during the apple vegetation period is a priority in the cultivation technology of this fruit tree species. The proposed studies aim at collecting information on the control of diseases and the microlepidopter population in order to establish the phytosanitary status of apple plantation. The research was carried out in the USAMV - Bucharest didactic field, in the apple orchard, and all apple varieties were studied, where the degree of attack was calculated based on the frequency and intensity of the diseases. The distinctive Golden Orange variety was the most attacked, with the Podosphaera leucotricha shoots at 70% and the intensity of 85%. This variety has the same high sensitivity to Venturia inaequalis, namely 80% frequency and 65% intensity. Microlepidopter surveillance in the apple orchard was performed using the pheromone trap (AtraPom). Pheromone traps were placed in the tree crown from late April to June. They were placed on three diagonals and 1.5 m high. Weekly observations highlighted that the first catches were recorded at the beginning of May (3 adults / trap), with a maximum flight in the in the second decade of May (7 adults/trap) and the last catches were in the second decade of May (2 adults/trap), with a single flight corresponding to the first generation.
