METHOD FOR CULTIVATION OF ONLY LATE RIPENING SOY VARIETIES FOR GRAIN, MAINLY IN DROP IRRIGATION SYSTEM

摘要

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 are carried out. Microelements are applied, desiccation and combine harvesting of beans for grain are carried out. Microelements and macroelements - manganese, calcium, sulphur, are dosed together with irrigation water, in particular, within the period of budding, microelements Co, Mo, B at the ratio 200-300, 100-200, 500-1000 g/hectare respectively, and calcium at the ratio 20-30 kg/hectare, within blooming period - microelements - Zn, Cu, B at the ratio 300-400, 250-350, 150-300 g/hectare and sulphur at the ratio 9-12 kg/hectare. During beans formation, microelements Mo, B at the ratio 50-75 g/hectare and manganese at the ratio 1000-1500 g/hectare, during grain filling Mo, Zn, B at the ratio 50-75, 35-55, 125-155 g/hectare respectively are applied.;EFFECT: increase in productivity, of grain quality of especially late ripening soy varieties in drop irrigation system.;1 tbl
