Abstract: The conditions of old-irrigated typical sierozem soils of the Kashkadarya region, when studying the sowing of rapeseed, oil radish, barley, peas and blue mustard in pure form, as well as a mixture of peas+oil radish as green manure crops in summer and autumn, the yield of biomass per hectare was 19,3-30.2 tons, in the spring 22.1-35.1 tons. The highest yield (30.7-39.6 or 7.2-11.4 t/ha additionally), of which marketable yield 29.8-39.1 t/ha, seed tubers yield 21.2-29.2 t/ha, the multiplication factor within 6.4-8.8 for medium early potato varieties Kondor, Arizona, Saviola and Bardoshli-3 was recorded using peas, gray mustard and a mixture of peas+oil radish as winter green manure crops. Plant development (the growing season lengthened to 2-10 days, 67.2-83.6 cm high; multi-stem 4.2-5.7 or more 1.1-1.8 pcs; powerful tops 404.4-495.3 d), the formation of productive, healthy (yield of tubers 617.5-998.8 g, number of tubers - 6.7-11.2, average weight of one tuber - 76.2-93.1 grams) bushes and crops, yield (30.7-39.6 t/ha, including marketable yield 29.8-39.1 t/ha, yield of seed tubers 21.2-29.2 t/ha, multiplication factor within 6.4-8,6) with high seed qualities of various varieties of potatoes.
Key words: siderate crops, green fertilizers, biomass, productivity, yield of commodity and seed crops, reproduction coe? cient, seed quality.
