Adaptive properties of chickpea (Cicer аrietinum)
(Полтавський державний аграрний університет, 2024) Bahan, A. V.; Zhornyk, I. I.; Баган, Алла Василівна; Жорник, Ірина Іванівна
The disease resistance is one of the most important features of chickpea adaptation to the adverse environmental conditions. The most common diseases of chickpea in the Forest-Steppe of Ukraine are fusarium and ascochitosis, which affect plants at all stages of vegetation.

Climatic factors play one of the main roles in shaping the productivity of leguminous crops. Under favorable weather conditions and proper agricultural background, the chickpea yield can reach 2,5–4,2 t/ha, under extreme growing conditions (drought), the yield drops to 0,7–1,0 t/ha. In particularly dry years, chickpeas compete with peas in terms of productivity.
Formation of grain yield in corn hybrids of different FAO groups depending on sowing dates and plant density

Formation of productivity of any agricultural crop depends on many factors. First of all, the soil and climatic conditions of the crop growing area, varietal or hybrid composition, seed quality, sowing dates and plant density, and strict adherence to all methods of cultivation technology are important. Corn hybrids of different maturity groups differ in morphological and biological properties. Thus, obtaining the potential yield of an individual genotype is possible under favorable conditions for the growth and development of plants, including high-variety agricultural machinery and natural conditions. The maximum yield of high-quality corn grain is formed under the condition of the optimal ratio of all structural elements: weight of 1,000 grains, number of rows of grains in an ear, number of grains in a row, number of grains on one ear, length and diameter of an ear. If one structural element is insufficiently developed, the yield can be compensated by other components. Since individual elements of the structure are formed at different stages of organogenesis, different conditions are necessary for their successful development. The hybrids used in our research revealed peculiarities in the formation of elements of the crop structure, depending on the timing of sowing and stand density. The sizes of the cobs that formed on the corn plants varied little under the influence of sowing dates and plant stand density, but were characteristic of a certain biotype. Studies have shown that all factors of the experiment affect the growth, development of plants and the formation of elements of the structure of the corn grain crop. According to the results of the measurements, it was established that the best indicators of all structural elements were observed for sowing hybrids of different maturity groups in the optimal period - the third decade of April. The highest values of all indicators were observed in the Olkani hybrid, which is explained by the genotypic features of this hybrid.
Formation of the productivity of corn hybrids depending on the duration of the vegetation period
(Полтавський державний аграрний університет, 2024) Ulizko, V. M.; Bahan, A. V.; Улізько, В. М.; Баган, Алла Василівна
Corn hybrids, which are characterized by a long growing season and an extended period from flowering to full grain maturity, have increased resistance to damage by stem rots, compared to premature forms and a short second period of plant development ("flowering-full grain maturity").
Formation of the yield of winter wheat varieties depending on the duration of the vegetation period
(Полтавський державний аграрний університет, 2024) Hurba, V. S.; Bahan, A. V.; Гурба, В. С.; Баган, Алла Василівна
One of the main indicators of the suitability of the variety for the main areas of winter wheat cultivation is the duration of the growing season. This important indicator has a fairly large amplitude of fluctuation, which is due to both genetic features and a set of external growing conditions.
Seed productivity of mustard varieties depending on sowing rate
(2025) Shakalii, S. M.; Bahan, A. V.; Шакалій, Світлана Миколаївна; Баган, Алла Василівна
Fluctuations in climatic resources, with a tendency to increase temperature, today require an expansion of the range of agricultural crops, including oilseeds. This is possible by introducing more drought-resistant crops into the crop rotation, which are able to easily adapt to different growing conditions. One of such crops is white mustard1/2/3.
The effect of humic growth stimulants on the productivity of chickpea (Cicer arietinum L.) varieties
(2024) Bahan, A. V.; Shakalii, S. M.; Yurchenko, S. O.; Marenych, M. M.; Mykhailenko, H. H.; Баган, Алла Василівна; Шакалій, Світлана Миколаївна; Юрченко, Світлана Олександрівна; Маренич, Микола Миколайович; Михайленко, Галина Григорівна
In organic farming, the use of plant growth biostimulants in crop cultivation technologies, including chickpea, has become widespread. The purpose of this study: to investigate the manifestation of productivity elements and the yield of chickpea varieties depending on the treatment with an organic growth stimulator. The study employed the following methods: field – to determine the level of yield, laboratory – to investigate the elements of productivity of chickpea, and statistical – to assess the reliability of experimental studies. By treatment options, the complex application of the product during pre-sowing seed treatment and foliar feeding of plants during the growing season was distinguished. The effect of organic growth stimulant on the increase of productivity elements of chickpea in this variant of the experiment was noted by an average of 10.0%. The greatest effect of the preparation was found in the complex treatment of seeds and plants of common chickpea in terms of seed weight per plant (24.0%). They were identified by the influence of varietal properties on the productivity elements of common chickpea varieties Triumf and Pamiat. The Pamiat variety with the seed treatment + foliar dressing variant was the best in terms of chickpea yield, but the Triumf variety had the greatest effect of the growth stimulator on the yield increase. Close correlations were found between seed weight per plant and thousand-kernel weight, number of beans per plant and number of seeds per plant, and yield with plant productivity and thousand-kernel weight. The findings of the study are recommended to be used to adjust the elements of chickpea cultivation technology to increase productivity in production conditions.
