The quality of the seeds of corn hybrids subject to the methods of their harvesting and drying

Goal. To establish the peculiarities of formation quality seeds corn hybrids, to determine optimal harvesting dates and drying methods, which can be used obtain high-quality seed material reduce energy costs for its processing. Methods. Laboratory — indicators sowing (weight 1000 seeds, germination, moisture); field study yield properties hybrids (yield dry grain); mathematical-statistical dispersion analysis statistical processing data reliable differences between them. Harvesting experiments were carried out by simulation on laboratory equipment in production conditions with involvement industrial harvesters dryers. Results. Abnormalities at stages ripening, harvesting, revealed. At stage mass increased, both actual terms matter, occurred when grain dried a moisture content 28–30%, depending maturity group weather climate conditions. drying, germination was formed ripeness, humidity, heat resistance condition level (not lower than 92%) reached humidity 32–40%. In process, ratio heating temperature established, during increased 2–8% compared control (ventilation cobs). Conclusions. it is recommended start 28–32%, physiological occurs. For cobs up 32%, regime should within 35–40 °C, 40–45 °C. consumption, allowed grain, but not higher 22%, several injury, growth strength, varietal purity material.
