Myronenko F. Agrotechnical basing of cultivation techniques for spring rape under Donetsk region conditions.

Research subjects: spring rape. Research objectives: Study of influence of preceding crops, the models of primary tillage, sowing terms, models and rates of sowing on the yield. Methods: fild, laboratory, PC. Theoretical and practical results: Dependence of yield of spring rape varieties from preceding crops, the models of primary tillage, terms of sowing, models and rates of sowing. The recommendations for cultivation of spring rape were released. Novelty of introduced: For the first time under Donetsk region conditions the complex influence of preceding crops, the models of primary tillage, terms of sowing, models and rates of sowing was considered in yield and quality seeds and the rational complex of those varieties cultivation was developed. Implementation degree: The complex of agrotechnical methods for cultivation of spring rape was recommended to production. Effectiveness: Complex of agrotechnical techniques permits to produce seeds up to 1.5-1.7 t/ha. Sphere sector of implementation: Agricult ural production.
