Abstract
It has been established that the formation of the yield of agricultural crops is related to a complex of factors, among which changes in soil and climatic conditions at the global, zonal and regional levels occupy an important place. It was found that in order to overcome the negative impact of these factors, an important scientifically based measure is the creation of modern high-yielding varieties and hybrids of agricultural crops, resistant to temperature and water stress factors, which, when grown in scientifically based technologies, are able to stabilize the formation of high yields under conditions of drought and elevated temperature regime. It was determined that moisture conditions have a significant impact on the growth and development of chickpea plants, as they determine the availability of nutrients and the supply of moisture, which contributes to the increase in the intensity of growth processes. It was established that the application of mineral fertilizers significantly affects the linear dimensions of chickpea plants. When using the mineral fertilizer system, the reliable increase in the height of chickpea plants in the branching phase was from 11,4% to 22,1%. In a dry year, nitrogen fertilizers had a greater effect, in a year favorable for moisture availability – all types of fertilizers. It was found that when liquid organo-mineral preparations were used, the best growth and development of chickpea plants was observed in variants treated with Seed Treatment, Antistress (SG Protector), Extra and Polymicrostim. Against the background of the application of mineral nitrogen (N30+N30), the increase was 1,8–8,0% in comparison with the specified options without the application of fertilizers.
