(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Velichi, Eugen
An experiment was set up in 2013 for watermelons, which had as purpose the identification of some treatment variants which would prevent the occurrence of the attack of some pathogenic agents specific to them. The variants of treatment were the following: V1 not treated control sample, V2 – Topsin 500 SC-0.1%, V3-Alert-0.1%, V4 - Folpan 80 WG0.15%, V5 - Folpan 80 WG-0.1%+ Topsin 500 SC – 0.1%. The experiment was placed in randomized blocks, with strict compliance to the experimental technique requirements. During the vegetation period, symptoms produced by Fusarium oxysporum f. sp. niveum fungus which produces the fusarium wilting of watermellons (Velichi E. 2006), have appeared differentially at each experimental variant. Other diseases, like the ones produced by the attack of Colletotrichum lagenarium fungus which produces the curcubitaceae anthracnose or by the attack of Sphaerotheca fuliginea fungus (Iacob Viorica, Hatman, M., Ulea, E., Puiu, I. 2000) which produces the mildew of cucurbitaceae, did not manifest in the watermelons experiment which were subject to the experiment. Production’s harvest was done in stages. The variants: V2 – Topsin, V3 - Alert - 0.1% and V5 - Folpan 80 WG - 0.1% + Topsin 500 SC – 0.1% have achieved statistically differentiated productions against V1 – not treated control sample. Variant V4 – Folpan 80 WDG – 0.15 % has achieved a production a bit larger than the not treated control sample, but without statistic insurance

Some researches concerning the resistance mechanism determination of potato to wart produced by Synchytrium endobioticum through biochemical analyses
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Saghin, Gheorghe; Bodea, Dumitru; Enea, Ioan-Cătălin; Murariu, Danela
The paper presents results concerning the resistance mechanism determination of potato to wart, caused by Synchytrium endobioticum, through biochemical analysis, in 10 potato resistant and susceptible genotypes to above pathogen, relating to: dry matter and moisture contents, ash, total nitrogen, total crude protein and starch contents , titratable acidity, catalase and polifenoloxidaze activities, ascorbic acid and total free amino acids contents. Following the analysis carried out on resistant and susceptible potato genotypes to the pathogen was found that indicators refering to dry matter and moisture content, ash, ascorbic acid, titratable acidity and starch contents no guarantee expression of the resistance degree or susceptibility level to pathogens. It is interesting the analyzes of total nitrogen and crude protein contents from tubers, catalase and polifenoloxidaze activities and total free amino acids contents. Thus we can say, after the first analyzes conducted in this direction, the potato genotypes resistant to pathogens, contain over 0.9g nitrogen/100g tissue tuber crude protein over 5.6% total free amino acids content, over 0.40% from d.s., catalase units less than 110 and below 1.70 micromoles of ascorbic acid oxidized by enzyme in 1 gram of tuber tissue for one minute. It is necessary to continue this type of research on a much larger number of resistant and sensitive potato genotypes and take into account other analyzes to those mentioned in this paper, regarding to quality of the protein content, the essential amino acids content, alkaloids, amides, the study of albuminoidal substances compozition etc., which would prevent the cellular system development of the fungus in potato tubers.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Velichi, Eugen
An experiment was set up with different cultivars of tomatoes in 2015 - 5 variants (4 hybrids and one variety). Those cultivars were: V1 - Ace 55 VF (control sample), V2 –SV52215 TD F1, V3 –Chelse F1, V4 – Rosaliesa F1, V5 – Mirsini F1. The experiments had as purpose monitoring the occurrence and evolution of the attack of some specific pathogenic agents at tomatoes, in the conditions of a droughty year. Also, it was monitored the correlation between the attack degree (G.A.%) of the mentioned pathogenic agents, production and the quality of the production. The experiment was placed in randomized blocks, with strict compliance to the experimental technique requirements. During the vegetation period, symptoms produced by viroses had appeared differentially at each experimental variant. Remotely, there were signalled also clear symptoms produced by stolbur (Mycoplasma). Other diseases, like those produced by the attack of some bacteria species (for example, Xanthomonas campestris p.v. vesicatoria) or fungi (for example, Phythophthora infestans, Colletrotrichum coccodes etc) have manifested in the tomatoes crop, but without raising any issues. Production’s harvesting was done in stages. Among the results of the production, achieved variant wise, differences insured statistically had been obtained. In the climatic conditions of the year 2015, the most productive cultivar was Mirsini F1. The control sample variety Ace 55 VF has proved to be the least attacked by viroses, but also which achieved the smallest production.

Beekeeper’ income volatility. Case study: beekeeping exploitations in Romania during the 1962 to 2011
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Măgdici, Maria; Bodescu, Dan; Moraru, Radu-Adrian; Boghiță, Eduard
The purpose of this paper is to determine the impact of honey yield variation on beekeepers revenue in Romania. The period for which investigations were carried out is 50 years to highlight the influence of a centralized economy and then of a under development market economy on the financial situation of beekeepers. The main research tools used were the indices of elasticity of prices and incomes based on the honey offer and on the consumer’s incomes. Results indicate a diminution in production capacity coupled with a significant increase in yield average. It was also revealed a significant volatility in the Romanian beekeepers revenues correlated with a low elasticity of honey prices compared with the dynamics of consumer’s incomes and with the total honey yield. During the 1962 to 2011 in Romania the incomes from honey production were by 43,3 millions with variations from 18,1 millions $ between the 1962 to 1966 to 109,3 millions $ between the 2007 to 2011. Thus, the increase of incomes from honey production was of 502.7 % while the honey yield increased by 183,8%.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Vasiliu, Mihaela-Păpușa; Tomița, Daniela-Ivona; Sachelarie, Liliana; Popovici, Diana
Poor and unbalanced diet influences oro-dental health, but in the same time, some disorders of the stomatognathic system (edentation) may produce nourishement changes. Eating disorders may have consequences, sometimes irreversible ones, upon some systems (digestive, immune, cardiac, etc.) and can manifest deficiencies in key moments of human development. In our study, conducted on 35 patients, aged 55-85 years, using a questionnaire food, we watched the frequency of fruit and vegetable consumption. The results highlighted the poor consumption, more obvious in case of the elder persons, the consequences being reflected throughout the body. Nutritional status of patients is sometimes influenced by exogenous factors (educational level, income) so that in case of elder patients may occur malnutrition, that may affect functional capacity of the stomatognathic system.

The innovation - economic performance relationship. Conceptual approaches
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Coca, Oana; Mironiuc, Marilena; Ștefan, Gavril
The paper is aimed to find the answer to the questions: What do we understand by the term of economic performance of the enterprise? What is the impact of innovation on economic performance of the enterprise? The answer to these two questions was based using qualitative analysis methods, such as documentary analysis of various scientific publications. The paper analyzes specialized previous empirical studies and researches, whose results contribute to defining and understanding the concepts of "economic performance" and "innovation" and, also, the relationship that is created between them. The performance is an economic concept, variously defined in the literature. For example, a performance approach, favored by many authors, is in terms of efficiency, effectiveness and economy indicators. Other authors consider that performance is equivalent to increasing of economic indicators from one year to another (for example, turnover, profit, profitability, market share, sales etc.). Thus, an enterprise achieves economic performance if it registers higher economical results, than the previous year. The literature gives a special place to innovation process, as key determinant of economic performance. The innovation is an expensive process for the enterprises and serve its purpose, as long as the company using it is increasing the economic performance. So, it is considered that the performance is a function of productivity and efficiency. Productivity and efficiency are the effect of innovation and technology. These results can substantiate the decisions at microeconomic level concerning the innovative investment (as action to increase the economic performance of the firm) and at macroeconomic level, where decisions are concretized in policy of increasing the competitiveness of the national economy.

The place of agriculture in economic growth
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Ștefan, Gavril; Coca, Oana
Agriculture - economic growth relationship is the subject of many studies, with different methodology, content and perspectives. In this context, the paper presents an econometric analysis of macroeconomic level in order to measure the contribution of agriculture to economic growth equation and evaluating the causal relationship with industry. The econometric analysis undertaken, using OLS method (Ordinary Least Square or the method of least squares) and TSLS method (Two Stage Least Square or the method of least squares in two-stage). Contribution of agriculture is defined in terms of the agricultural GDP (gross domestic product) and the economic growth in terms of evolution of real GDP. The results reveal that agriculture occupies a secondary place in economic growth. Regarding the links between agriculture and industry, they are in favor of industry. Why? Because, in the agricultural GDP equation, the industrial GDP coefficient has a negative sign (-), and in the industrial GDP equation, the agricultural GDP coefficient is positive (+). Therefore, the industrial sector has greater benefits from industry-agriculture relationship and by effect of agriculture-growth relationship. Developing the agricultural sector deserves o priority position since growth in this sector helps the industry to grow further. However, capital investment in agriculture releases farm labor that often is not absorbed by the economy and emphasizes the degree of rural poverty. Thus, encouraging the industrial development by increasing agricultural sector, the position of rural poverty can increases. This reality indicates that agricultural development should not be hampered in favor of concentrating resources for industrial development and must be found an optimal balance between industry and agriculture, so the rural poverty to be alleviated and the economy to record a sustainable growth.

Empirical evidences regarding the role of innovation in economic growth
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Ștefan, Gavril; Coca, Oana
Innovation is the main market trigger that generates economic growth and development. Although studies in the field have pointed out numerous benefits that innovation brought to its creators and end consumers, not all companies manage to innovate. This paper aims to evaluate the impact of innovation upon economic growth, by computing the various indicators used to evaluate the management potential of innovation, the potential to create knowledge, the potential to innovate and collaborate, the performance of innovation activities and the level of economic development per country. The study was performed on the 27 European countries (excluding Luxemburg), using the information available in Eurostat statistics for the period 2008 – 2014. In order to find an answer to the research problem, this paper used the following data analysis methods: the ratios method, the correlation analysis, the comparative analysis. The results showed that there is a strong, direct, and measurable link between a country's level of economic development and its innovation ability, and the performance of innovation activities is influenced by their funding source (public or private capital).

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Zăpodeanu, Cezara-Valentina; Țenu, Ioan; Cârlescu, Petru-Marian; Arsenoaia, Vlad-Nicolae
Wheat brushing is a technological operation part of the grain seed grinding process, which aims to remove dust and adhering impurities to the surface of the wheat kernels as well as their brushes. By brushing the seeds gain a smooth and glossy surface, and the ash content is reduced by minimum 0.01%. In order to optimize the operating process a brushing installation – IPG - was designed and developed. The purpose of this study was to evaluate the effect of some functional and constructive parameters (speed of the rotor with brushes, the suction air flow rate, tapered shell type and the product feed rate) over the physical characteristics of grain seeds. The experimental results conducted using wheat kernels led to the conclusion that the percentage of broken seeds was influenced by rotor speed, product feed rate, the shape and size of the perforated shell holes of the brushing instalation drum; variations of the percentage of broken seeds up to 1.3% were recorded, depending on the constructive-functional parametres of the machine. A number of 144 experimental variants were studied in the research, the lowest percentage of broken grains being recorded at the maximum feeding rate of 600 kg/h. The optimum variants were established based on the analysis of the results referring to the percentage of broken kernels.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015) Oniga, Ersilia; Cârdei, Mihaela
Digital terrain models are used in wide variety of domains and applications, of which the most important are: orthorectification of aerial and satellite images, space object modelling, passageways designing, achieving slopes exhibition maps, hydrological modeling, etc. There are several techniques for data acquisition in order to create digital terrain models, such as photogrammetry, radargrammetry, interferometry, airborne laser scanning, surveying and geodetic and cartographic digitization. By using cartographic digitization, digital terrain models are created based on the digitized contour maps on existing maps, which were brought in digital format by scanning process, this method involving low costs and being reach of a large number of users. It must therefore assess the vertical accuracy of digital terrain models created by this method. To achieve results, first were created the digital terrain models based on contour maps and points of known elevations manually digitized on plans at 1: 1000 scale and maps at 1: 25000 scale, using an interpolation grid side of 5m and spline bicubic interpolation method. Then, were determined with precision, by GNSS technology, the coordinates of 18 control points. Based on the grid nodes elevations, using the spline bicubic interpolation method, were calculated the elevations of the 18 control points and then the differences between them and those accurately obtained by GNSS technology. By performing a statistical analysis of these differences, the vertical precision of digital terrain models created from contour maps was determined.
