INFLUENCE OF CROP ROTATION ON THE GROWTH AND DEVELOPMENT OF WINTER WHEAT

Abstract

Soils of the Republic of Karakalpakstan are salty and low in fertility. In such soils, the meliorative condition of soils should be improved and soil fertility should be increased for receiving high yield from agricultural crops. Field experiment was carried out in order to determine the influence of crops, which are included in the system of short-term crop rotation (1:2). In this, legumes (mung bean, sesame, soybean) were included in the system of short-term crop rotation as past crops, and it affected positively when it was sown in the following method: cotton: past crop mung bean for grain + mung bean for siderate + 20 t/ha manure then winter wheat: winter wheat
