Developmental Variations of Soyabean “Nafis” Sort Growing in Low Salinity Soils throughout the Aral Sea

Abstract

In order to develop the optimal sowing time, ensuring high and stable yields of soybeans of the "Nafis" variety in the Aral Sea region, field experiments were carried out on the experimental plot of the Karakalpak Scientific Experimental Station of the Research Institute of Grain and Leguminous Crops. The experience is multi-factorial. Sowing was carried out on three sowing dates: 1st, 2nd and 3rd ten days of April. The results of the study showed that when cultivating soybeans of the Nafis variety in the Aral Sea region, in order to obtain the highest grain yields, sowing should be carried out in the first ten days of April.
