METHOD OF CULTIVATING SOYA FOR GRAIN ON IRRIGATED LANDS Russian patent published in 2002 - IPC

FIELD: agriculture. SUBSTANCE: method involves harvesting precursor plants; providing skim plowing; destroying perennial weeds by applying herbicides at crown formation stage; disking upper layer and applying organic and mineral fertilizers such as phosphorous and potash fertilizers; after skim plowing, providing strip mellowing of soil to depth of 0.3-0.35 m with strip spacing of 1.4-2.0 m; providing arrangement of mellowed strips at an angle of 20-35 deg with respect to longer field side; slitting at the same strip spacing at an angle of 30-45 deg with respect to strips, with slit depth being maintained within the range of 0.40-0.45 m; harrowing at early spring period; providing continuous application of herbicides in case of appearance of cold-resistant weeds; sowing crops with row spacing of 45.60 cm and 70 cm at seeding rate of 500-600 pieces per 1 hectare; applying herbicide at the rate of 1.5-2.0 kg per 1 hectare at the stage of appearance of 1-3 leaves; providing vegetative irrigation, with inter-rows being mellowed at irrigation intervals; harvesting crops upon maturing of 80-85% of beans. Method allows soil to be provided with water supply for the whole growing period. EFFECT: increased efficiency, reduced irrigation norm and increased seed yield. 5 dwg
