Wheat ripening dynamics in Uzbekistan for harvesting it in earlier periods

摘要

At present, the results of research of the ripeness dynamics of cereal for harvesting it in the earlier periods in the condition of Uzbekistan. During the researches, quality indicators were studied of wheat sorts of middle and late ripening “Krasnodar-99” and “Kroshka” as well early ripening “Chillaki” in wax (biological) ripening and technical (complete) ripening periods and the grain that was harvested in early periods. It was known that the grain of wheat becomes empty by results of experiments if it is harvested 16 earlier than complete ripeness. When it is harvested 12 days earlier, the grain ripens more completely than the previous. However, its fullness does not become at enough level. If the cereal is harvested 8 days earlier than complete ripeness, namely when it is harvested in the wax ripeness period, the fullness of the grain does not become less than the fullness of the grain that is harvested after complete ripeness.
