Comparing industrial grain and seed for sowing of corn in the conditions of Uzbekistan
Аннотация
It is necessary to harvest the matured crop of corn at low cost and on time to produce qualitative seed. Therefore, research was conducted about the determination of the maturing period of the corn in the period of waxy maturity of the corncob and physical-mechanical properties of the corn were studied too, for comparing industrial grain and corn for seeding. It was defined that during the experiment the corn may be harvested in its waxy matured period, namely 10-16 days earlier than maturing completely for producing industrial grain in Uzbekistan. However, this harvesting method can not be used to produce corn for seeding. If the corn-crop is harvested earlier for producing industrial grain, there might be an opportunity to do next agronomic and mechanized operations such as ploughing or providing the field with organic fertilizers before snowy days. However, for producing corn-seed, of course, the completely ripening period of the corn-grain should be waited. Studying the physical-mechanical properties of the corn is important to determine the parameters of the corn-harvester and thresher machines for harvesting seed-corn.
