Actual aspects of development of mechanization of trial works in plant growing

Abstract

The purpose. To study state and development of technical maintenance of selection-and-seed-growing work with grain and leguminous cultures in Ukraine. Methods. Analytical, statistical, modelling and empirical research of working organs, units of machines and technological operations. Results. Overall performance of machines available in selection centers for mechanization of selection-and-seed-growing processes is determined at work with grain and leguminous cultures. The gained results of researches are directed on development and introduction in agrarian science of perspective machines for basic operation of selection — sowing. Basic directions of development of technical maintenance of selection and seed-growing of grain and leguminous cultures are brought. Conclusions. For mechanization of selection-and-seed-growing processes of grain and leguminous cultures there were developed more than 40 machines, process equipment and devices which were made by small parties or were recommended (>75%) to serial production. Production of selection machines should be supported by state.
