The article presents the results of research on potato varieties in the Polissia zone of Ukraine. According to them, the adaptive potential, phenotypic stability and resistance to stressful environmental conditions were calculated based on the ''yield'' feature. According to the results of a comprehensive assessment, it was established that the general adaptive capacity according to the absolute coefficient of adaptability is characteristic of the following varieties: Prada, Sanibel, Riviera, Vzirets, Bellarosa, Zhytnytsia, Rodynna, Lilly, Yavir, Knyazha, Sluch, Toscana, Challenger. High stress resistance was found in potato varieties: Prada Predslava, Challenger. Genetic plasticity, which has a high degree of compatibility of the ''genotype-environment'' factors, was established in the varieties: Prada, Sluch, Bellarosa, Rodinna. According to the coefficient of variation, a high degree of variation (variability) was established in the varieties: Sluch, Vzirets. Varieties: Prada, Challenger, Predslava had slight variability. This assessment will contribute to the selection of potato varieties for profitable and economically profitable potato farming.

Molting is a common practice used by the commercial egg industry to rejuvenate flocks. The aim of this study was to evaluate the effect of marble powder on egg production performance of laying hens during premolt and postmolt periods. For this purpose, 69126 Hy-Line White 36 (W-36) laying hens (80 weeks old) were obtained from a commercial egg production farm. All of the chickens who lived to 90 weeks of age were subjected to the forced molting program. The time of the molting program was determined according to the body weight loss of the chickens. On the tenth day of the molting program, when hens in the group had lost an average of 23.10% of their body weight, feeding was resumed. Egg production performance was tracked for hens who lived to 100 weeks of age. It was observed that egg production (% hen-day) ranged from 42.69 to 69.51%, 0 to 51.59% and 0 to 74.68% in the premolt, molt and postmolt periods, respectively. The results of this study suggest that the addition of marble powder to forced molting programs of laying hens has a beneficial effect on egg production, particularly during the postmolt period.

This research aimed to determine the ecological elasticity of soybean varieties’ performance of different maturity groups in the Sumy, Ternopil, and Mykolaiv regions. In the course of the research, 10 fast-growing, 6 early-ripening, 4 middle-early, and 3 mid-ripening varieties of domestic and foreign selection were used. The results of the analysis of the obtained data show that the formation of varieties’ yield capacity is directly dependent on the length of the growing season, the amount of precipitation, and the temperatures. It was found that the highest level of yield capacity (2.75 t/ha on average) is formed by early-maturing soybean varieties, among which the Merlin variety is characterized by the highest yield - 3.08 t/ha.

Research was conducted using Andrada winter wheat variety created at the Agricultural Research and Development Station Turda. The crop was treated with two types of foliar fertilizers, Folimax Gold and MicrofertU which were applied in two tillage systems: conventional and no-tillage. The main purpose of this paper is to assess the influence of foliar fertilization in the two systems of conventional tillage and conservative systems with no-tillage. Various growth stages of the wheat crop, in achieving high yields and quality indices were assessed. The promotion and identification of physiological mechanisms in wheat are useful in assessing biological development, correlated with the productivity elements of winter wheat. Measurements of assimilation of the physiological parameters and chlorophyll concentration were performed on the standard flag leaf five days from the last treatment, using foliar fertilizers considering the duration of adaptation of tissues in flag leaf. Measurements were performed five times per plant and five plants per variant, with three repetitions in June. Technology used in wheat cultivation showed that the net assimilation, physiological parameters, and production were higher, registering higher values for the conventional system (tilling), ranging between 27-30 μmolm

The operation of harvesting medicinal plants is one of the important factors, which influences the quality of plant material and thus its value. In order to optimize the cultivation technologies and to adapt them to the local conditions, INMA Bucharest has developed and tested a multifunctional equipment for the mechanized harvesting of medicinal plants (annual and perennial), cultivated on small and medium areas. This equipment, of small capacity, equipped with interchangeable working parts, performs the harvesting operation by cutting, at a certain height from the ground. The paper presents the results obtained when testing the experimental model of Multifunctional equipment for harvesting medicinal and aromatic plants in the crops of three species of medicinal plants, grown on small areas. Determining for each crop some qualitative working indices (average working height, cutting degree, collecting degree, losses, etc.) as well as some energy indices (working speed, hourly fuel consumption, working capacity, etc.) allows the evaluation of the technical and working performances of the Multifunctional equipment for harvesting medicinal and aromatic plants.

Soil microbial community is of high importance in preserving soil functions and its ecosystem goods and services. Within field experiences, regarding agricultural sustainability and the resilience of agro-ecosystems, a study was conducted to evaluate the evolution and abundance of the soil microbial community under the influence of environmental and agro-technical factors. For this purpose, periodic determinations of the microbial community on the depth of 0-20 cm were made in the plots cultivated with wheat, maize, soybean and a mixture of perennial grasses and legumes. In the experimental field, organic fertilizer materials (manure compost in doses of 15, 30 and 60 t/ha) and synthetic fertilizers (complex fertilizer in formula 20.20.0, in doses which varied with the specific consumption of crops and the amount of manure compost) were applied. At the same time, in the laboratory, biometric determinations were made regarding the antifungal efficacy of soil microorganisms after 5 days from incubation. The results of microbiological analyses showed that the microbial population from soil inhibits the in vitro development of the pathogen tested.

To determine the adaptability and stability of yield and its related traits during drought conditions in triticale, eleven contemporary Bulgarian cultivars were studied according to the indices yield, number of productive tillers, 1000 kernel weight and number of grains in spike, applying four parameters: regression coefficient and deviation from regression, ecovalence and stability variance of Shukla. Drought had a significant effect on the yield related traits, which differed considerably according to the different parameters of stability. The best combination of stability and adaptability according to number of productive tillers and 1000 kernel weight was observed in Bumerang and Doni 52. The parameter number of grains in spike behaved in a rather complex manner under conditions of drought and the separate stability parameters related to contradictory results. The widest adaptability according to this parameter was observed in cultivars Rakita, Lasko and Respekt. The stability and adaptability parameters of the separate yield traits was not functionally related to the same parameters of yield, which determined the investigated cultivars as developed according to a complex of traits and being suitable for growing under variable environments.

The stability and adaptability parameters of the separate yield traits was not functionally related to the same parameters of yield, which determined the investigated cultivars as developed according to a complex of traits and being suitable for growing under variable environments.","PeriodicalId":44979,"journal":{"name":"AgroLife Scientific Journal","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44707897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
