FIELD: agriculture, in particular, plant growing and feed production, may be used for growing of spring rape in fodder crop as postcut forage crop. ^ SUBSTANCE: method involves preparing soil and seeds; sowing; providing care for young crops; harvesting. Seed sowing is carried out during period of mass development of cruciferous weeds and die-off of first generation of wintered cruciferous fleas Phyllotreta spp. Spring rape is grown in postcut forage crop. Before seed sowing, soil is cultivated by rotavation or two-three-staged disking by means of harrows to 8-10 cm depth immediately after harvesting of preceding crop. Seed sowing is performed during 2-3 days after harvesting of said crop. Spring rape is cultivated in single-course complete fodder crop rotation mode. Winter wheat is used as preceding crop. Early ripening rape seeds with growing period of up to 100 days are commonly used. In the Middle Urals zone, rape seeds are sown in June, 15 to 30. ^ EFFECT: increased yield of spring rape grown for forage in risky agriculture regions at intensive utilization of plowed field in fodder crop rotation mode without use of pesticides. ^ 4 cl, 6 tbl |
