Abstract
This article discusses the impact of nitrogen fertilizers on the growth, development and yield of corn when grown in the northern region of Afghanistan. The study was conducted in 2020-2022 with the use of urea nitrogen fertilizer (urea) with increasing doses: N0 (control), N140, N180, N220 and N260 kg/ha. In all variants of the experiment, an increase in plant height and the number of corn leaves relative to the control was observed against the background of the use of nitrogen fertilizer. The sharpest increase in the accumulation of dry matter by the time of harvest was observed in variants where nitrogen fertilizer was applied at a dose of N260 kg/ha -176.7 c/ha, which is 56.25% more relative to the control over an average of three years of research. Analysis of the elements of the structure of the corn crop showed that the use of increased doses of nitrogen fertilizer (N260 and N220 kg / ha) contributed to an increase in the number of grains in the cob, the mass of 1000 grains, and as a result, higher yields of grain and corn straw. The yield index at N260 and N220 kg/ha of urea doses was 40.07 and 40.52%, which is 10.42-11.66% more painful relative to control on average over three years of research.
