Abstract

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.

Highlights

The climate condition of Uzbekistan allows harvesting the crops 2-3 times a year
One of the main factors for earlier harvesting of cereal is that the harvesting period should be constituted correctly by connecting to the cereal's ripeness dynamics
Results the changing of ripeness dynamics between 10th of May and 9th of June in sort “Krasnodar-99” of wheat showed that, the grain moisture changed from 68,6 to 18,3 percent between that period, creamery period of grain went on from 10th of May to 24th of May and made up 10 days, dough period of the grain continued from 25th of May to 29th of May and involved 5 days; wax ripeness period of grain, namely declining from 40 percent of moisture began on 30th of May, it reached on 18,3 percent on 9th and ripened completely

Summary

Introduction

The climate condition of Uzbekistan allows harvesting the crops 2-3 times a year. It is achieved for this by seeding the peanut, corn, rice-plant, potato, leguminous, and vegetables-melons after harvesting the wheat crop. They are demanded to plant earlier as possible for more harvesting by repeat plants. The cereal should be harvested earlier than usual, namely in the period of wax ripeness. One of the main factors for earlier harvesting of cereal is that the harvesting period should be constituted correctly by connecting to the cereal's ripeness dynamics. Observing the ripeness period of cereal in the condition of Uzbekistan and according to the result defining earlier harvesting period of cereal is important
