Abstract
Abstract The research was carried out to study the effect of basic tillage methods, means of chemicalization, and biologization on the yield of corn grain and the content of mobile phosphorus in the arable (0–25 cm) layer of typical heavy loamy medium-thick low-humus chernozem. The work was carried out in 2021–2022 in the Chechen Republic. The content of humus (according to Tyurin) in the soil of the experimental plot was 3.6%, the content of mobile phosphorus and potassium (according to Machigin) was 15 and 300 mg/kg, respectively, and the reaction of the medium was neutral (pHKCl = 7.1). In the experiment, a Pioneer 9678 corn hybrid was grown, and the predecessor was winter wheat. The scheme of the experiment included the following options: reception of the main tillage (factor A): plowing to a depth of 25–30 cm; disking by 10–15 cm; chiseling by 30–40 cm; fertilizers, biological product and green manure aftereffect (factor B): without fertilizers, biological product and green manure; N120P60K60 + green manure; biological product V417 + green manure; N120P60K60 + V417 + green manure. Disking, which ensured the formation of corn grain yield at the level of 4.75 t/ha, was the most effective in the experiment against 3.65 t/ha for plowing and 4.35 t/ha after chiselling. The content of mobile phosphorus in the soil was 21, 15, and 16 mg/kg, respectively. The use of the V417 biological product in combination with the aftereffect of green manure against the background of disking provided the highest corn yield on average for 2 years: 5.10 t/ha. The highest content of mobile phosphorus, 26 mg/kg at a balance of 60 kg/ha with an intensity of 236%, was found in the variant with disking and the use of fertilizers and a biological product in combination with the aftereffect of green manure, which was 1.5–2.0 times higher than the values of these indicators with plowing and chiselling.
