Abstract

An important direction of modern agrotechnologies of crop production is the greening of intensive technologies and energy conservation, this contributes to the use of biological preparations that can increase yields, improve grain quality, increase profitability by saving mineral fertilizers and protective equipment. Therefore, field experiment was conducted during 2019-2021 in the dry-steppe zone of chestnut soils of the Volgograd region. The scheme of the experiment included four sites with late-autumn; early-spring; late-spring application dates and control, without the use of nitrogen fertilizers. All records and surveys were carried out according to the methodology of the state variety testing of agricultural crops: calculation of germination, determination of tillering coefficient, determination of the weight of aboveground biomass of plants, the density of productive stems. As a result of studying the issue conducted in various weather conditions of the test years, it was established that the period of application of nitrogen fertilizers had a significant impact on the growth, development and yield of experimental crops. The highest yield indicators were recorded at the time of early spring application of nitrogen fertilizers @ 38.0, 30.8 and 40.2 q/ha in 2020, 2021 and 2022, respectively. With the delay in the application of nitrogen fertilizers in the spring, the yield decreased by 8-13% during the observation period, and 32.94 28.2 and 35.8 q/ha in 2020, 2021 and 2022, respectively. The introduction of nitrogen fertilizers in autumn, as close as possible to the end of the growing season, led to a decrease in yield by only 2-4% and amounted to 36.5, 29.8 and 39.5 q/ha in 2020, 2021 and 2022, respectively.
