METHOD FOR CULTIVATION OF LEGUMINOUS CROPS ON IRRIGATION IN CONDITIONS OF ARID ZONE OF NORTHERN CASPIAN Russian patent published in 2021 - IPC A01B79/02 A01G25/09 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in intensive technology of leguminous crops cultivation under irrigation conditions. Method includes sowing and pre-sowing of organic fertilizer of sapropel - 30 t/ha and semi-tillage manure - 30 t/ha. In October, after harvesting of the precursor, the main treatment of MTZ-1021+PLN-4-35 soil with soil tillage by 22–24 cm is carried out. In the spring at approach of physical ripeness harrowing with tooth harrows C-11+BZT-1 in two tracks is performed. Early spring period cold-resistant weeds are destroyed by loosening of the upper layer at depth of 2–3 cm when the tooth harrows move across the ploughing. Heat-loving weeds at soil temperature in layer of 8–10 cm are not lower than +14÷+16°C is mechanically eliminated by displacement of tooth harrows by diagonal-cross direction. Soil is piled up after sowing, its sprouting is performed with cultivator paws MTZ-1021 + KPS-5 at depth of 8–10 cm. When soil crust is formed after rains, harrowing is performed with gradual reduction of depth of subsequent cultivation to 6–8 cm. Sowing is carried out by seed drills MTZ-1021+-3,6 with seeding depth of 5–6 cm and spacing of 70 cm. Vegetation watering is carried out with sprinkler plant Bauer Rainstar; during vegetation mineral fertilizers are fractionally added with dose N₃₀P₃₀K₃₀ with irrigation water.

EFFECT: method provides higher yield of leguminous crops with development of agrotechnical techniques using a mobile sprinkling installation Bauer Rainstar in arid conditions.
