METHOD OF SOY CULTIVATION FOR GRAIN, MAINLY IN DROP IRRIGATION SYSTEM Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method envisages stubble ploughing of a forecrop, soil processing with herbicide, application of fertilisers, real tillage, prevernal breaking up of soil and levelling, preplanting irrigation and cultivation at a depth of 4-5 cm. The method also envisages soil compaction after and before seeding, harrowing of sprouts, irrigation during the vegetation period, desiccation and harvesting. Macrofertilisers - posphorus, potassium, calcium are applied in the topsoil at 0-0.08 m when prevernal breaking up is carried out. Nitrogen is dosed together with irrigation water in the phonological phase of tillering, budding, blooming, bean filling, grain ripening at a dosage of 30-35, 15-20, 8-12, 6-17, 20-37 % respectively. Sulphur at a dosage of 70-80% is applied according to the set dosage in the phonological phase of tillering, budding, blooming, bean filling, grain repining. The rest 20-30% of sulphur is applied in the blooming phase when foliage spraying is carried out. Microelements - molybdenum, boron, cobalt, copper, zinc and macroelement - manganese are applied by spaying 125-200 l/hectare of the solution when foliage spaying is carried out in the blooming phase.

EFFECT: increase of yield and quality of soy grain, decrease of mineral fertiliser and microfertiliser consumption.
