Poberezhna L. Formation of chickpea productivity per grain depending on fertilization with macro and microelements in the conditions of the Western Forest Steppe

The dissertation theoretically substantiates the long-term research of domestic and foreign scientists on the cultivation of chickpeas per grain, in particular, issues related to the impact of various technological methods on the growth and development of the crop, the formation of grain yield, and overall productivity. The relevance of the topic, goal, task, object, and subject of research are clearly formulated in the work. The scientific novelty and practical significance of the obtained results are emphasized, in particular, the use of pre-sowing application of mineral fertilizers in combination with foliar fertilizing with micro fertilizers, which contributed to the achievement of chickpea grain yield at the level of 2.94–3.24 t/ha. Based on an analysis of scientific sources, it has been established that the chickpea crop has high economic and energy efficiency and is competitive compared to other leguminous crops. According to the economic assessment, the most effective technology for growing chickpeas of the Yaryna variety, which included the pre-sowing application of mineral fertilizers in combination with foliar fertilization with micro fertilizers, turned out to be the most effective. This technology provided the highest net profit in the amount of UAH 33,366 per hectare with a profitability level of 170.6%. Economic efficiency was slightly lower in the Skarb variety, with a net profit of 27,366 hryvnias and a profitability level of 139.9%, while in the Pamyat variety, these figures were 26,686 hryvnias and 136.48%, respectively.
