The evaluation results of the maize-grain yield cultivated on the chernozem leached according to the level of fertilization and agro-meteorological conditions of the years 2012-2021 are presented. Maize-grain yields obtained from the unfertilized variant witness varied from 0.42 t/ha to 6.03 t/ha. Administration of fertilizers on the natural background on average for 9 years led to the increase of maize yields from 3.39 t/ha to 5.40 t/ha, the production crop yield was 27-59%. At phosphorus levels, the crop yield increased from 6% on the level of 1.5 mg to 26-28% - 3.0-3.5 mg/100 g of mobile phosphorus versus the background level N120K30 mg/100 of soil. In the P3.5K30 mg/100 of soil PK variant, the increase in harvest vs. control was 27%. In nitrogen variant on the PK background in doses of 30-150 kg/ha the increase in maize production was 38-59% compared to the control variant and 11-32% to PK variant. The optimal soil phosphorus level for chernozem cambic in grain maize cultivation was 3.0-3.5 mg/100 g of soil Machigin method and the optimal nitrogen doses were 90-120 kg/ha. |
