Bazileva Y. Injury of seed corn hybrids and methods of its prevention

Object of study - damage corn and its impact on crop and harvest seed properties, methods of preventing injury. Purpose - to establish characteristics injury seed corn in their collection and post-harvest processing, develop technical and technological methods to prevent injury. Methods - laboratory, field, mathematical-statistical. Results of the developed technical and technological methods to improve the quality of production provided seed harvesting stages and post harvest handling. In provender plant research facilities "Dnepr" (Dnepropetrovsk region). Overall injury seed corn decreased by 40-50%, the number makroinjuries embryo does not exceed 2-3%. When sowing these seeds, field germination was increased by 8-12% yield - at 0,81-1,03 t / ha, upgraded economic performance of commodity grain - net profit was 450,6-952,0 USD. / ha profitability 76,0-77,6%. Novelty. Defined biotic-abiotic factors that significantly affect the level of injury and the quality of seed corn. Established tolerances injury maize hybrids and developed technical and technological measures that reduce injuries seeds, improve its seeding and harvest characteristics. Recommended: method of chemical pre-treatment of seeds new formulation (patent for utility model number 41088). A new method of determining injury to corn seeds. Sector - agriculture.
