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 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.

(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.

(2025) Bahan, A. V.; Shakalii, S. M.; Hapon, S. V.; Yurchenko, S. O.; Chetveryk, O. O.; Nahorna, S. V.; Баган, Алла Василівна; Шакалій, Світлана Миколаївна; Гапон, Світлана Василівна; Юрченко, Світлана Олександрівна; Четверик, Оксана Олександрівна; Нагорна, Світлана Вікторівна
Actuality. Today, landscape designers are required to introduce a new assortment of plants into culture, in particular annual ornamental crops. The purpose of the study is to investigate the manifestation and relationships of morphometric indicators and varietal characteristics of plants of the genus Tagetes L. Materials and methods. The research material was 10 varieties of marigolds: Orange Prince, Sugar and Spices, Moonlight, Hawaii, Red Brocade, Cupid Lemon, Bolero, Mandarin, Marietta and Manjestik. The following research methods were used: field – determination of morphometric indicators and varietal characteristics of plants and the duration of the flowering phase of marigolds; laboratory – determination of varietal characteristics of the plant, leaves and inflorescences; statistical – identification of relationships between the studied indicators. Research results. The longest period of “beginning-mass flowering” was established in the varieties Red Brocade and Marietta (over 30 days). Medium-sized varieties were distinguished: Orange Prince, Moonlight, Hawaii and Manjestik. The Manjestik variety was noted for the number of inflorescences on the plant (97 pcs.). A semi-spreading plant habit and moderate branching of the plant were revealed in most varieties. The Hawaii variety was distinguished for leaf size. The largest baskets were noted in the varieties Orange Prince, Moonlight, Hawaii, Sugar and Spices. The type of flowers in the inflorescence of marigolds was established: tubular-reed, tubular and reed. The Marietta and Manjestik varieties were distinguished for the presence of a two-color basket. A strong relationship was established between the indicators: diameter and length of the basket with a peduncle, the indicator of plant height at the beginning of flowering and during full flowering; correlations of medium strength between the indicators: length of the basket with a peduncle and length of the peduncle; length and width of the leaf; as well as the inverse relationship between the number of inflorescences on the plant and the length and diameter of the basket. Conclusions. The duration of the period “beginning-mass flowering” in varieties of marigolds of the genus Tagetes L. was established. Morphometric indicators of the plant in the flowering phase and the manifestation of varietal characteristics of the plant, leaf and inflorescences in varieties of marigolds were determined. Relationships between the studied indicators were noted.

(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.

(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.

(2025-12-03) Маренич, Микола Миколайович; Marenych, M. M.; Koba, K. V.; Гангур, Володимир Васильович; Hanhur, V. V.; Юрченко, Світлана Олександрівна; Yurchenko, S. O.; Шакалій, Світлана Миколаївна; Shakalii, S. M.; Баган, Алла Василівна; Bahan, A. V.; Четверик, Оксана Олександрівна; Chetveryk, O. O.; Рибальченко, Анна Михайлівна; Rybalchenko, A. M.
In regions with insufficient rainfall or different climates, the use of irrigation systems is an important element of corn growing technology. The variation in corn yield on non-irrigated lands is 533% and 200% greater than on irrigated lands. Corn yield also depends heavily on sowing density. The optimal plant density is an unstable value. Field studies were conducted in conditions of unstable moisture in the central part of the Forest-Steppe of Ukraine, which according to agro-climatic zoning belongs to the zone of unstable moisture. The experimental design included: assessment of the characteristics of weather conditions during the years of research (2021–2023) and their impact on seed yield (factor A); determination of seed productivity of female components linesof hybrids of different maturity groups P4/440, P5/320, P6/240 (factor B); the impact of growing hybrids with and without irrigation (factor C); the effect of different seeding rates on seed yield (60, 70, 80, 90 thousand seeds per ha-1) (factor D). The test results show that during the change in corn productivity depending on genetic properties, seeding rate and irrigation, the late-ripening hybrid P4/440 was characterized by the highest grain yield when grown under irrigation, with a seeding rate of 90 thousand similar seeds per ha-1 a decrease in the seeding rate from 90 to 80, 70, 60 seeding rate thousand seeds ha-1 was accompanied by a decrease in the yield of seeds of female components lines: in the early-ripening hybrid P6/240 - by 0.31, 0.63 and 1.10 t ha-1 or 5.7, 11.5 and 20.1%, in the mid-ripening hybrid P5/320 - by 0.59, 1.08 and 1.42 t ha-1 or 9.8, 17.9 and 23.5%, in the late-ripening hybrid P4/440 - by 0.39, 0.74 and 1.28 t ha-1 or 6.0, 11.4, 19.8%. The greatest influence on the formation of yield is the irrigation factor - 53%. Genetic properties influenced 28%. gradual increase in the yield of seeds of female components lines of culture when increasing the seeding rate from 60 to 70 thousand seeds ha-1 (by 0.01 t ha-1) and reaching a maximum at a rate of 80 thousand seeds ha-1 (by 0.05 t ha-1). But with an increase in the seeding rate to 90 thousand ha-1, the seed yield sharply decreased by 0.13 t ha-1. The highest yield in variants without irrigation was observed when using the minimum seeding rate - 60 thousand seeds ha-1. A gradual increase in the seeding rate without irrigation led to a negative result, in particular, a decrease in the average yield for corn hybrids by 0.07–0.31 t ha-1 or 1.8–7.9%. Hybrids reacted differently to the seeding rate and cultivation on rainfed and irrigated land. Early ripening hybrid P6/240, mid-ripening P5/320 and late-ripening P4/440 hybrids formed the highest seed yield when grown under irrigation with a seeding rate of 90 thousand seeds ha-1. When grown without irrigation, the best conditions for the formation of plant components and high yield were noted at the lowest seeding rate of 60 thousand seeds ha-1. The minimum seeding rate ensured the production of seeds with a high mass of 1,000 seeds.
