Abstract
The article presents the research materials on assessing the effect of liquid organomineral fertilizers on the productivity indicators of grain corn. The studies were conducted in 2022-2024 in Kama zone of the Republic of Tatarstan on gray forest soil. Experimental design: 1) control - without fertilizers; 2) application of BATR 40N at a dose of 4 l/ha in the phase of six true leaves of the crop; 3) application of a tank mixture of BATR 40N at a dose of 4 l/ha + BATR Zn at a dose of 1 l/ha in the phase of six true leaves of the crop. The object of research is DKS 3006 corn hybrid. The soil of the experimental plot: humus content is 3.5...4.7% (according to Tyurin), mobile phosphorus (according to Kirsanov) - 140...155 mg / kg and exchangeable potassium (according to Kirsanov) - 112...120 mg / kg of soil, pH (salt extract) - 5.3-6.6. The experiment was repeated 3 times, the plots were placed systematically, the area of each plot was 126 m2. The weather and climatic conditions during the years of research turned out to be contrasting - 2022 was favorable (HTC 1.3), 2023 and 2024 were droughty (HTC 0.8 and 0.9, respectively). Foliar feeding contributed to an increase in yield (the average increase over the years of research was 3.9-10.7 c/ha), improved quality (starch content increased by 2-4.4%, nitrogen content in grain by 0.1-0.14%). The greatest effect was achieved with the use of a mixture of fertilizers BATR 40N at a dose of 4 l/ha + BATR Zn at a dose of 1 l/ha. On average, over the years of research, the yield increase was 10.7 c/ha, the starch content increased by 4.4%, and the grain weight per cob by 15.56 g (due to an increase in the number of grains and the thousand-grain weight). The average NPK content in grain, depending on the variant, was: nitrogen 1.03-1.17%, phosphorus – 0.3-0.39%, potassium – 0.32-0.35%. The average removal of nitrogen was 202.6-246.5 kg/ha, phosphorus 66.4-77.6 kg/ha, potassium – 318.7-363.2 kg/ha.
