METHOD FOR PRE-SOWING TREATMENT OF RICE SEEDS WITH MANGANESE IN THE CONDITIONS OF THE KRASNODAR REGION Russian patent published in 2021 - IPC A01C1/00 A01G22/22 A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and namely to rice cultivation technology. According to the method, the rice seeds are preliminarily examined for their manganese content. The treatment of rice seeds belonging to mid-season varieties obtained from at least three checks is carried out. One of the varieties is used as a check variety. Manganese is added to the seeds of other varieties before sowing at the rate of 4 kg/ha. After harvesting, rice seeds are examined for their manganese content. Then they are divided into three groups with different manganese content: the first group includes seeds containing less than 30 mg/kg of manganese, the second group includes seeds containing 30-45 mg/kg of manganese, and the third group includes seeds containing more than 45 mg/kg of manganese. Moreover, if rice seeds belong to the first group or the second group, they are treated with a 1.0% aqueous solution of manganese by the semi-dry method with working fluid consumption of 10 liters per 1 ton.

EFFECT: invention increases the yield of rice and reduces the consumption of manganese fertilizers because of highlighting the need for pre-sowing treatment of rice seeds with manganese.
