INFLUENCE OF SEED POTATO MASS AND PLANTING DENSITY ON PRODUCTIVITY OF EARLY POTATO

Abstract

Results are given from investigations into the influence of seed potato mass and planting density on productivity and quality of Latona cultivar of early potato under conditions of the south of Kyrgyzstan. It was established that the yield of early potato significantly depended on the factors studied. The optimum density for planting medium and large tubers was revealed to be 65.4 ths per ha. In these variants, potato productivity after deduction of seeds was high. Marketability of tubers from seed potatoes weighing 80-100 g was 4.25-9.2 % higher as compared with that from small and medium seeds. The yield structure and marketability of early potato was analyzed depending on seed potato mass and planting density. As planting density increased, the average weight of tubers decreased with a part of small fractions in the harvest increased, and large ones decreased.
