Studying the Influence of Sowing Time on the Chemical Composition of Soybean Plants in the Southern Regions of Uzbekistan

Abstract

Soy is important, protein, technical legume. In recent years, in our country, the interest of producers and farmers in growing this crop has increased, as evidenced by the annual increase in sown areas from 100 hectares to 300 thousand hectares. Currently, soybeans are sown as the main and secondary crop after winter wheat. Seeds are imported from other countries; these varieties are introduced in our dry and hot climate.

The purpose of our research is to study the effect of sowing time on the chemical composition of seeds and yield, as well as the adaptation of varieties of Russian selection in the dry and hot climate of Uzbekistan. Varieties of the Russian selection “Slavia” and “Chara” and local varieties “Madaniyat “B”, “Madad” and “Orzu” were studied. The studied varieties in the south of Uzbekistan are superior in yield and quality indicators.
