Abstract: FIELD: agriculture. 
     SUBSTANCE: method includes treatment of the leaves 3 times per growing season - in the stage of true leaves, flowering, fruit formation, with Megafol, Vitazyme agents, manual seeding, application of mineral fertilisers with irrigation water by drop irrigation. In October, after harvesting the predecessor – spring barley, primary tillage by MTZ-1021 + PLN-4-35 is performed with subsoil ploughing to a depth of 22 to 24 cm. In the spring, at the onset of physical ripeness, harrowing is performed with toothed harrows of S-11+BZT-1 in two tracks. In the early spring, cold-resistant weeds are destroyed by ripping the top layer to a depth of 2 to 3 cm while moving the toothed harrows across the ploughing, and thermophilic weeds, at a temperature of the soil in the layer of 8 to 10 cm no lower than +14 to +16°C, are mechanically eliminated by moving the toothed harrows diagonally-crosswise.  The soil is rammed after sowing, seedlings are loosened with cultivator shovels of MTZ-1021 + KPS-5 to a depth of 8 to 10 cm. When a soil cap is formed after rains, harrowing is performed with a soil reduction in the depth of subsequent cultivations up to 6-8 cm. The seeds are planted to a depth of 7 to 8 cm with row spacing of 280 cm. The soil is rammed after sowing, vegetation irrigation is conducted with 150 m 3 /ha of irrigation water. In the growing season, mineral fertilisers are applied fractionally at a dose of N 110 P 110 K 80  with the irrigation water by drop irrigation. Ammonium nitrate is introduced with the irrigation water as an additional fertiliser. Foliar treatments are performed with a rod sprayer ONSh-600 with a consumption of agents as for the application rate: Megafol - 0.5 l ha, Vitazyme - 1.0 l/ha in the stage of true leaves, flowering, fruit formation. 
     EFFECT: method comprehensively provides plants with trace elements throughout the entire growing season when applying additional foliar fertilising with Megafol and Vitazyme agent.
