METHOD FOR CULTIVATION OF VERY LATE RIPENING SOY VARIETIES WITH HEAT AVAILABILITY 3001-3500°C, 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, soil compaction before and after seeding, harrowing of sprouts and irrigation within vegetation period, microelements application are carried out as well. Foliage spraying with microelements Mo, B, Co, Cu, Zn at the ratio 100-200, 500-1000, 200-300, 250-350, 300-400 g/hectare is carried out within the phases of "tillering", "budding" and "blooming" until closing of rigs. Working liquid for irrigation of vegetative mass is applied at the ratio 200-250 l/hectare. The mentioned microelements with irrigation water at sesquialteral - triple dosage is applied within the phase "bean formation and filling" when the rigs are closed. Desiccation and crop harvesting are carried out after ripeness of cropper.

EFFECT: increase in productivity and of oil content in soy seeds.
