CULTIVATION METHOD OF MAIZE HYBRIDS ON GRAIN IN CONDITIONS OF LEACHED BLACK SOIL OF WESTERN CISCAUCASIA Russian patent published in 2019 - IPC A01G22/20 A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to plant growing. Method includes planting of maize in the last decade of April to a depth of 6–7 cm. After 5–6 days, winter triticale is sown across rows of maize to a depth of 2–3 cm with a seeding rate of 2.5–3.0 million viable seeds per hectare. In this case, mid-season hybrids of maize are used with FAO indexes range from 301–400, the seeds of which are sown on the field of crop rotation. In the third decade of October on the crushed crop residues of spring or winter wheat is applied dry litter semi-rotted manure in amount of 25–30 t/ha. Then, at the end of April, loosening is performed simultaneously without turning the top layer of soil, mixing crop residues with manure and soil, and introducing seeds with a seeding rate ensuring plant density of 50–60 thousand pieces per 1 ha, the seeding rate is determined by formula: where SR is the seeding rate, kg/ha; G – density of standing plants, pieces / ha; W – weight of 1 thousand seeds, g; L – losses during laboratory germination, %.

EFFECT: method allows to increase the yield of maize hybrids in conditions of leached chernozem of Western Ciscaucasia.
