METHOD OF SOYA SEEDS PRODUCTION UNDER IRRIGATION CONDITIONS, MAINLY FOR INTERMEDIATE VARIETIES, AND METHOD OF PRIMARY SOYA SEEDS BREEDING UNDER IRRIGATION CONDITIONS Russian patent published in 2017 - IPC A01C1/00 A01C7/00 A01H1/04 A01G1/00 A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Soya seeds production method in irrigation conditions provides for soya seeds wide-row sowing, watering, plants care and harvesting. For sowing seeds are used, produced by primary seed growing method, containing: 1 – preliminary reproduction nursery garden with original seeds sowing rate of not more than 250 thousand pcs. of germinating seeds per hectare; 2 – 1st year nursery garden; 3 – 2nd year nursery garden; 4 – superquality stock seeds section; 5 – selected grain section. Sowing is carried out with rate of 380–400 thousand pcs. of germinating seeds per one hectare. At that, moisture content of active soil layer is maintained as not less than 67–80–63 % HB by scheme: 67 % HB during shoots-blooming periods; 80 % – from blossoming to seeds filling; 63 % during filling - complete ripeness of seeds period, and last watering is carried out in first decade of August. Method of soya primary seed growing under conditions of irrigation involves successive reproduction of original soya seeds in breeding nursery gardens of 1st and 2nd years, superquality stock seeds and selected grain sections. Additionally introduced is preliminary reproduction nursery garden, wherein in all three reproduction nursery gardens performing negative sampling with removal of non-typical plants and impurities during blossoming and ripening.

EFFECT: methods provide for faster production of soya seeds, reduction of seeds heterogeneous varieties occurrence and improving sowing qualities of seeds.
