RIULS

Repository of Iasi University of Life Sciences, ROMANIA

Welcome to RIULS!

The mission of the University’s institutional repository is to manage, preserve and disseminate, in open access, the academic and institutional output of the university’s academic community. It also aims to promote values and personalities belonging to Romanian agricultural science, by storing digitized versions of rare books and manuscripts from its collections.

The repository is part of the international movement known as open science, which promotes free access to scientific literature. This translates into maximized impact of the work carried out by researchers, contribution to improving access to knowledge, increased visibility of the institution through the works of its authors and improvement of its search engine ranking.

All documents deposited in the repository receive a unique and persistent identifier called a Handle, thus guaranteeing perpetual access to scientific output through permanent links.

RIULS Repository of Iași University of Life Sciences is indexed in Duraspace, OpenDOAR,CORE,Google Scholar,BASE (Bielefeld Academic Search Engine) and ROAR (Registry of Open Access Repositories), global Directories of Open Access Repositories.

The effects of defoliation caused by Stereonychus fraxini L. beetles on the radial growths in forest ash stands in Eastern Romania
(Editura “Ion Ionescu de la Brad” Iași, 2025) Blaga, Tatiana; Lungu Constantineanu, Camil-Ștefan; Blaga, Mădălina-Elena
The research aimed at understanding the influence of defoliation caused by the Stereonychus fraxini L. beetles on the growth and vitality of forest stands with ash trees in their composition or ash forest stands. Complete, unrepeatable defoliation has important consequences on tree vitality, especially in the case of early defoliation, causing a 50-70% reduction in the vegetative mass compared to the witness trees unaffected by defoliation; the effect of defoliation manifests differently, depending on the age of the stands, being more pronounced in young stands than in older ones; repeated defoliation within the same year causes partial or total drying of the trees towards the end of the vegetation season. Prevention of defoliation is possible through pest control methods. Pest control treatments manage to prevent defoliation and to put an end to mass multiplication of insects.

The influence of climate change on the drying of fir tree in the Roznov area (Neamț county, Romania)
(Editura “Ion Ionescu de la Brad” Iași, 2025) Blaga, Tatiana; Busnatu, Romeo; Lungu Constantineanu, Camil-Ștefan; Blaga, Mădălina-Elena
Due the climate change, an alarming increase of the phenomenon of drying of coniferous trees, has been observed. The attack of ipides found in fir stands is a secondary attack that occurs following the physiological weakening of the trees and their drying as a result of the lack of precipitation and high temperatures. The entire Eastern range of the Eastern Carpathians is vulnerable to drought, especially the stands located at altitudes below 800-1000 m and with S, S-E or S-W exposure, where the precipitation level is low and the temperatures are quite high, the mountains themselves constituting a barrier for the precipitation coming from the West. An urgent measure to stop the phenomenon, is the urgent valorization of the already affected wood mass and its exploitation. Trees that are lanceolate, attacked by mistletoe, fungi, etc. should also be extracted. For regeneration, deciduous or other species with higher resistance to drought and heat stress should be used.

Biodiversity and dynamics of harmful insects in raspberry crops during the 2024 agricultural year, under the ecological conditions of the Eastern Carpathians
(Editura “Ion Ionescu de la Brad” Iași, 2026) Bădeanu, Marinela; Cebonaș, Irina; Sandu, Tatiana
In the context of increasing pest pressure on mountain horticultural crops, this study aims to evaluate the biodiversity and population dynamics of harmful insects in raspberry (Rubus idaeus) crops during the 2024 agricultural year, under the specific ecological conditions of the Eastern Carpathians. The research was carried out in two commercial plantations located in Suceava and Neamț counties, using standard entomological sampling methods: chromotropic traps, pheromone traps, visual observations, and plant material sampling. Throughout the growing season, 12 harmful insect species were identified, the most common being Byturus tomentosus, Drosophila suzukii, Amphorophora agathonica, and Aphis idaei. A significant correlation was observed between climatic conditions (temperature and humidity) and the population dynamics of the pests, particularly during the months of May to July. Altitude and plantation exposure were also found to influence the structure of entomological communities and the level of infestation. The results contribute to a better understanding of current phytosanitary risks and can serve as a basis for the development of effective integrated pest management strategies, tailored to the ecological conditions of the mountainous area of the Eastern Carpathians.

Productive and energetic evaluation of growing corn and soya mixture for silage
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Hnoevyy, V.V.; Hnoevyy, I.V.; Kotets, H.I.; Pastukhov, V.I.; Melnyk, V.I.
The crop yield of green mass of corn and soya mixtures during the wax ripeness of corn grain of the variety “Dniprovska 310” and the full ripening of soya grain of the variety “Podilska – 1” grown on the agricultural backgrounds without fertilizers and (NPK)45 has been determined during the scientific and research experiment. The seeding rate of corn and soya in the mono specific crops was 25 kg/ha and 80 kg/ha, respectively, but in three mixtures - corn 25 kg/ha, soya 20 kg/ha, 40 kg/ha and 60 kg/ha, that was, respectively, 25 %, 50 % and 75 % of the seeding rate of soya in the mono specific crops. The use of mineral fertilizers provided the increase in the yield of corn and soya mixtures for the above options by 2000 kg/ha, 3700 kg/ha and 3000 kg/ha, respectively. The highest crop yield of green mass – 40400 kg/ha was produced by the option with mineral fertilizers and the seeding rate: corn - 25 kg/ha and 40 kg/ha, it exceeded the mono specific crop of corn by 2200 kg or 5.8%. At the mixed sowing of corn and soya the content of protein in the dry matter of crop yield of the mixture on the agricultural background without fertilizers increased 1.30 - 1.61 times but on the agricultural background with fertilizers - 1.49 - 1.69 times as compared with the mono specific crop of corn and the content of fat increased 1.17 - 1.67 times and 1.07 - 1.37 times, respectively. The use of corn and soya mixtures had a positive impact on the main energetic performances of their growing as compared with mono specific sowing of corn. The yield from 1 ha of gross and metabolizable energy increase, respectively, by 12.4 - 10.7% and 10.3 - 11.5%, the energy consumption of 100 kilograms of protein decreased nearly twice. The replacement of corn silage by corn and soya one in the composition of feed mixtures for dairy cows promoted the increase in their daily milk yields by 3.0 kg or 11.3% and fat in milk – by 0.2 % at the absolute favorable performances of energy consumption for milk production.

Research on the quality of meat following slaughter
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Muntean, C.; Boișteanu, Paul-Corneliu; Lazăr, Mircea; Lazăr, Roxana
The appreciation of the quality of the meat is made multifactorial only through the physico - chemical factors to exclude any level of subjectivity from appreciation. The paper presents research on hybrid BUT 6, intensively grown, referring to color, softness, texture of the meat, boiling losses. To express the color of turkey meat, the brightness was determined, which depends on the light reflection power. The tenderness of the turkey meat determines its taste value being determined by the ease with which it is cut or chewed. Expression of fleshiness was performed by primary statistics calculated using Warner Bratzler shear forces. The texture of the meat was appreciated by the following coefficients: hardness, cohesiveness, adhesion, guminess, elasticity and masticability. Boiling losses are the ability of the meat to lose a share of its own weight. This technology of meat is a criterion for expressing the water retention capacity of prepared meat. Boiling losses vary according to the structural features of muscle tissue, thicker fibers record a higher rate of water loss. Very significant results in the expression of the complementary colors of red-green and yellow blue, as well as a significant difference in cohesiveness between the two anatomical regions studied, were recorded.
