CULTIVATION METHOD OF SOYA FOR GRAIN IN IRRIGATED CROPPING Russian patent published in 2009 - IPC A01G1/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: method includes skimming of precursor, tillage by killer, introduction of fertiliser, ploughing with layer circulation, early-spring soil tillage and smoothing. Preplant water application and cultivation is implemented for depth 4-5 cm. Also it is implemented sowing, packing of soil before and after sowing, shoots harrowing, irrigation during the vegetation and dessication of crops. At late autumn on true area with laid out soil layer of top layer for depth 0-0.12 m along the lines east-west there are formed with two sloping surfaces of different flat combs with vertex with angle at vertex β=180°-(θ+α). Height of combs is installed by calculation from expression: H=(b_s-b₃)·tgα·tgΘ/(tgα+tgΘ), m. In early spring period it is implemented combing of cold-resistant weeds and mount of combs. At sowing of soya seeds vertex of comb and south slope are compacted up to values, defined from the expression: m. At compaction of comb vertex at north slope and simultaneous sowing of seeds into seeds bed it is implemented groove for depth of seeds sowing and it is laid flexible spray pipeline of trickle irrigation system.

EFFECT: receiving of guaranteed harvest of soya grain in irrigated cropping at cultivation in conditions of acutely continental climate.
