METHOD FOR FOLIAR FEEDING OF RICE AGROCENOSIS WITH ZINC-CONTAINING FERTILIZER IN THE CONDITIONS OF KUBAN Russian patent published in 2022 - IPC A01C21/00 A01G22/22 A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to methods of growing rice. The method includes a preliminary study of rice for zinc content, ranking it into three groups with different zinc content and determining the need to treat rice with a 1.0% aqueous solution of zinc, depending on the zinc content in it. Vegetative rice plants in the tillering phase are analyzed for their zinc content after dry ashing at 525±25°С by the atomic absorption method and rank them into three groups. The first group includes plants containing less than 35 mg/kg zinc of aboveground dry weight; to the second - 35-45 mg/kg. The third group includes plants containing more than 45 mg/kg of zinc aboveground dry weight. If rice plants contain less than 45 mg / kg zinc, then foliar feeding is carried out with a 0.1% aqueous solution of zinc with a working solution consumption of 300 l/ha.

EFFECT: method provides for an increase in the yield of rice and a reduction in the consumption of zinc-containing fertilizers by determining the need for foliar treatment of vegetative rice plants with zinc.
