Production and distribution of local food contributes to responds to the needs of consumers in terms of desire to support the local economies and responsibility for the environment. In local food resources, food production and processing, trading this food and its consumption occur in a relatively small geographical area. Benefits resulting from the functioning of local food systems are not only related to satisfying food demand, but also bringing specific social benefits. They allow to maintain the vitality of rural areas, especially in peripheral locations. In addition, locally produced food is not anonymous, it is also characterised by higher quality than mass-produced food. The purpose of the work is to identify the determinants and preferences of consumers regarding the places of purchase of local dairy products. The study was carried-out in 2019 using an interview questionnaire on a randomly selected group of respondents. The survey involved 308 respondents from the Podkarpackie Voivodeship, of which 298 consumed dairy products, and 255 respondents bought local dairy products (85.6% of respondents consuming dairy products). It was discovered the interest in buying local dairy products is quite high - 85.6% of respondents consuming dairy products bought them. A significant percentage of respondents (91.4%) indicated the availability of local dairy products in retail trade. Whereby, in the case of units located near the place of residence, 7.5% of respondents faced significant restrictions on access to these products, while 33.7% pointed to frequent shortages in the product range. This indicates the need to improve the flow of these products in distribution channels.

Wheat is a cereal that plays an important role in agriculture, for feed and human food. It is well known that the wheat (Triticum aestivum L.) has a large and complex genome (2n = 6x = 42 chromosomes) that makes difficult the genetic researches. Assessing genetic purity and varietal identification are important topics in wheat seed quality control. Several approaches that can be used to exploit new methods for genetic purity assessment and varietal identification of wheat are currently available in various international laboratories. Techniques based on morphological identification involve intense effort, making it sometimes difficult to verify crops varieties. Using molecular markers in order to determine the purity and variety identification of different seed types seems to be a better approach. Nowadays in the world there are numerous wheat varieties and cultivars with different properties. The molecular markers are not influenced by environment conditions and this makes them play an important role not only for seed purity evaluation but although for research purposes. Taking all that into consideration we can say that DNA-based methods using PCR technique are always useful tools to determine authenticity and purity not only for wheat varieties but for other crops. A better understanding of the factors controlling purity and varietal identification, as well as the effective utilization of new and developing genetics and genomics technologies, have great potential to improve the genetic purity assessment.

The paper aimed to present the evaluation process of the economic potential of agrarian enterprises and its links to the financial results of such enterprises in Ukraine. The study used the data of financial statements of different types of agrarian enterprises of Ukraine and the statistical data provided by the Ministry of Agriculture. The authors proposed updated definitions of "economic potential of the enterprise" and "economic potential of the agricultural enterprise". During the analyzed period, the agricultural holdings had a relatively lower rate of economic potential, than farms. The production of cereals and leguminous has decreased by 1.8%. The meat production’s trend line predicted its gradual increase and milk production in 2020-2021 would decline up to 10 million tons if market conditions will stay the same. As a conclusion, the management of the economic potential of agricultural holdings and limited liability companies was more effective, than the one at farms, as bigger producers effectively restored and consistently kept their profitability after crisis reductions.

This experiment was carried out in 2019, in the cold greenhouse, covered with polycarbonate, in the early culture, in the experimental field of the Faculty of Horticulture Bucharest, and the lettuce was stored in the Postharvest Technology Laboratory at the Research Center for Studies of Food Quality and Agricultural Products of the University of Agronomic Sciences and Veterinary Medicine Bucharest. F1 lettuce hybrids were used: Centore, Analena, Alanis, Shangore and Tizian, fertilized at planting with Best starter 200 kg/ha, K-sol 80 kg/ha, Novatec classic 300 kg/ha and Orgevit 3000 kg/ha. For storage only 2 hybrids, Tizian and Shangore, were used with 2 fertilizers, respectively, Best starter and K-sol. The storage conditions were: in the normal atmosphere at 1°C, 95% humidity and 20% oxygen and in the controlled atmosphere at 1°C, 95% humidity and 2% oxygen for 14 days. There were used 3 packaging variants: unpacked, packaged in food foil and packaged in food foil on cardboard. Plant growth and production were influenced by the fertilizer used, the best results being obtained by fertilizing with Best starter and K-sol, which is why these hybrids were chosen for storage. During the storage period it was observed that the greatest weight loss was in the unpackaged lettuce both in the normal and controlled atmosphere, regardless of the hybrid and the fertilization product used. The content in vitamin C was higher in hybrids fertilized with K-sol, but during the storage period there was a strong decrease especially for the lettuce from stored in controlled atmosphere, for all packaging variants. The acidity of the lettuce did not show major differences.

Field experiments were conducted for two successive seasons during 2017/2018 and 2018/2019 at ARDS Turda to asset the performance of three different facultative wheat genotypes under different sowing dates. The experiment was laid out in split plot design with three replicates and comprised of five dates of sowing, noted I to V (I-III sown in autumn, IV - V sown in spring), in main plots and three facultative wheat genotypes (Taisa, Ciprian and Lennox) in subplots. Two years results revealed that in autumn sowing conditions, facultative wheat sown at the end of Oct. - beginning of Nov. performed better in number of productive tillers/plant, number of grains/spike, weight of grains/spike and grain yield. In the 1st season, Taisa had the highest grain yield (7.80 t ha-1), but in the 2nd Ciprian performed better (7.63 t ha-1). In spring sowing conditions, the facultative wheat needs to be sown as early as possible, especially Taisa (long growth cycle, later heading time). A delay in spring sowing tends to decrease number of tillers/plant, number of productive tillers/plant, weight of grains/spike and grain yield. Lennox performed better than Taisa and Ciprian in both seasons.

Study was conducted in long-term field experiment (47 years) in irrigated vegetables cropping system on chernozem heavy loamy in Forest-Steppe zone of Ukraine. Different types of fertilization regimes were compared: mineral (NPK); organic (manure) and organo-mineral (manure + NPK). Humus content decreased by 10-12% after two 9-crops rotations compared to initial data (before irrigation) on all variants of experiment. Since the end of third 9 years cropping system humus has been increased up to 4.35% at the end of fifth crop rotation in organo-mineral fertilization regime. Mineral fertilization systems did not increase humus content compared to the control (without any fertilization). The highest humic compounds content in chernozem was observed on organic fertilization system. Long-term regular manure application led to significant increase of the content of humic complexes with calcium in comparison with mineral and organo-mineral fertilization regimes. Fulvic acids content was higher on variant with NPK application.

The objective of this study was to examine the productive performance, egg quality and reproductive parameters of commercial Arbor Acres (AA) broiler breeder hens fed different levels of corn distillers dried grains with solubles (DDGS). A total of 2340 AA broiler breeder hens, 26 weeks of age, were allocated for a 14-week experimental period in a feeding trial consisting of 3 dietary treatments (0, 10, and 15% DDGS), and 4 replicates per treatment. Each replicate consisted of a group of 195 hens (male to female ratio 1: 10). All experimental diets were prepared as iso-protein (16%) and isocaloric (ME 11.7 MJ/kg) and with similar content of total sulfur amino acids, Ca and available P. The use of DDGS up to 15% in AA broiler breeder hens diet did not have adverse effects on egg production, feed intake, feed conversion ratio and egg mass (P>0.05). DDGS, also led to a significantly increased yolk color intensity (P<0.001), while having no effect on egg interior and exterior quality, especially on eggshell quality, such as egg specific gravity. Fertility and hatchability of fertile eggs were not affected by the dietary DDGS levels. Based on the results, DDGS could be included up to a level of 15% in AA broiler breeder hens’ diet without any significant detrimental effects on the egg production, egg quality and reproductive performance.

The aim of this study was to evaluate the sensitivity of yellow mustard (Brassica juncea L) to plant regulators compound growth by the root length, root surface area, root volume, stem length and surface area. The experiment consists of three varieties of yellow mustard (RETRO, FELICIA and PRIMA) and eight growth regulators (Albit, Vermistimd, Antistress, Agrios, Regoplan, Biofoge, Stimulate, Fast start). The results showed that the growth compound regulator was the main factor causing the difference in root length and had no correlation with the variety. Different types of plant growth compound regulators have significant differences in the growth and development of mustard. For RETRO, the growth compound regulator VERMISTIMD significantly increased root growth compared with the control. In FELICIA, the length of root has changed under the influence of seeds inoculation with growth compound regulator BIOFOGE. However, the treatment of ANTISTRESS significantly inhibited the root length of FELICIA and RETRO. In the study of the PRIMA, all the growth regulators had no significant or inhibitory effect on the growth of the roots. In addition, there were also differences in the sensitivity of compound growth regulators to root and stem, for stem growth of FELICIA, the growth compound regulator VERMISTIMD has the opposite effect on the stem surface area and BIOFOGE has a significant impact on stem surface area of PRIMA.
