METHOD FOR CULTIVATION OF VERY EARLY RIPENING SOY VARIETIES WITH THERMAL CONDITIONS 1701-1900°C FOR GRAIN, MAINLY IN DROP IRRIGATION SYSTEM Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: stubble ploughing of a forecrop, soil processing with herbicide, application of fertilisers, real tillage, prevernal breaking up of soil and levelling are carried out. Thereafter, preplanting cultivation of seeds, inoclution, preplanting irrigation and cultivation at a depth of 4-5 cm are carried out. Hereafter, planting, soil compaction before and after planting are carried out. Harrowing of sprouts, irrigation, microelements application and intercultivation are carried out within vegetation period. Microelements Mo, B, Co, Mn, Zn and Cu are applied together with irrigation water at a rate 60…75, 18…25, 30…60, 15…75, 22.5…30 and 15…25 g/hectare respectively in the phase of "tillering-beginning of blooming", 80...100 g/hectare of Mo, 25…35 g/hectare of B, 40…80 g/hectare of Co, 20…100 g/hectare of Mn, 30…40g/hectare of Zn and 30…40 g/hectare of Cu are applied in the phase of "blooming - beginning of bean formation", 40…50 g/hectare of Mo, 10…15 g/hectare of B, 20…40 g/hectare of Co, 10…50 g/hectare of Mn, 15…20 g/hectare of Zn, 10…15 g/hectare of Cu are applied in the phase of "bean formation - beginning of bean filling", 32…40 g/hectare of Mo, 10…14 g/hectare of B, 16…32 g/hectare of Co, 8…40 g/hectare of Mn, 12…16 g/hectare of Zn and 10…16 g/hectare of Cu are applied in the phase of "bean filling -beginning of grain ripeness", 48...60 g/hectare of Mo, 15…21 g/hectare of B, 24…28 g/hectare of Co, 12…60 g/hectare of Mn, 14…18 g/hectare of Zn and 9…15 g/hectare of Cu are applied in the phase of "beginning of grain ripeness - complete ripeness". Desiccation and crop harvesting are carried out after ripening.

EFFECT: increase of yield, protein and fat content.
