Study of Some Physiological, Biochemical and Morpho-Economic Characteristics of Local and Foreign Soybean Varieties Grown as a Recurrent Crop in the Conditions of Navoy Region

Abstract

In the article, the variety "Selekta-201" of the foreign Russian selection, grown after the wheat harvest as a repeated crop in Navoi region, as a control, "Sparta" of the Krosnodar selection, "Nena" of the Kazakhstan selection and local "Ustoz-MMAn-60", "To'maris-MMAn-60" ”, "Oyjamol" soybean cultivars from physiological indicators during the true leaf and podding periods the results of the analysis of chlorophyll "a", chlorophyll "b" and total chlorophyll in plant leaves, the number of pods in one bunch of plants and the weight of 1000 seeds from the yield indicators, the amount of oil in the grain from the biochemical indicators were studied. In the conditions of Navoi region, an increase in the amount of chlorophyll "a", chlorophyll "b" and the total carotenoid was found in some varieties, while in some it was decreased and showed different productivity indicators.
