Abstract
The article presents the results of studying the effect of irrigation regimes and fertilizer rates on plant growth and productivity of new corn varieties Samarkand tishsimoni and Kumkishlok. It was revealed that maintaining the regime of pre-irrigation soil moisture at the level of 70-80% of the PISM and applying fertilizers at the rate of 30 t/ha of manure + N200P160K100 kg/ha has a positive effect on the formation of tall, leafy plants with an optimal leaf area of up to 0.80-1 .02 m2. The highest grain yield in the studied varieties (8.5-9.8 t/ha) was obtained with an irrigation regime of 70-80% PISM on an organomineral background of nutrition (30 t/ha of manure + N200P160K100 kg/ha).
