METHOD FOR IMPROVING TECHNOLOGY OF GUAR CULTIVATION USING IRRIGATION IN ARID CONDITIONS OF NORTH-WESTERN CASPIAN SEA REGION Russian patent published in 2023 - IPC A01G22/40 A01G25/02 A01B79/02 

FIELD: agriculture.

SUBSTANCE: method includes carrying out the main tillage, fertilizing, sowing and harvesting the guar. In autumn, after harvesting the predecessor, the main tillage of the soil MTZ-1021 + PNL 4-35 is carried out with a soil deepening of 22-24 cm. In the spring, when physical ripeness occurs, cover harrowing is carried out with tooth harrows MTZ-1021 + S11-U + BZT-1. When weed shoots appear, MTZ-1021 + KPS-5 cultivation is carried out to a depth of 5-6 cm. The pre-sowing application of the complex mineral fertilizer azophoska (N₁₆P₁₆K₁₆) is carried out - 150 kg/ha by physical weight using mineral fertilizer spreader ANTS-1000 + MTZ-1021, pre-sowing cultivation MTZ-1021 + S11-U, KPS-4.2 with simultaneous application of fertilizers. Sowing of guar seeds is carried out with a seeding depth of 5-7 cm, a row spacing of 70 cm, with a seeding rate of 220 thousand pcs./ha, treated by Prestige preparation at a rate of 1 mL per 1 kg of seeding material using a precision seeder, or single-seed seeding, with simultaneous placement of STV12 + MTZ-1021 drip tapes. The soil is sprayed before germination with the preparation Gezagard with the application rate of the preparation of 2.5 L/ha, the flow rate of the working fluid is 300 L/ha, MTZ-1021 + S11-U + boom sprayer OShN-12, with loosening of guar at phase 4-5 of the present leaf by cultivator lugs. During the growing season, Master N₁₈:P₁₈:K₁₈ preparation is applied through a drip irrigation system at a rate of 2 kg/ha. Protective measures against diseases and pests, pre-harvest two-time desiccation with the Flis preparation to reduce plant moisture, improve the quality of harvesting and reduce the cost of drying seeds, as well as harvesting with a Sampo brand combine at a grain moisture content of 16-19%.

EFFECT: method provides an increase in the yield of guar when cultivated in an arid climate.
