| Abstract | Results of studies on the influence of different fertilizer systems and pre preceding crops in the crop rotation on the productivity of sugar beet in the podzolized chernozem of Right-bank Forest-Steppe are given. Studies have shown that on average for 5 years the productivity of sugar beet root crops-to-clover at saturation of the crop rotation with nitrogen at rates of 45 and 90 kg/ hectare in grounds P45K45 and P90K90 was 44.6 and 49.9 kg/ hectare, respectively, and the productivity of sugar beet root crops-to-corn for silage was 43.4 and 49.5 kg/ hectare. For saturation of the crop rotation with manure at rates of 9 and 18 t/ hectare, the productivity of sugar beet roots-to-clover was 42.7 and 49.7 t/ hectare and the productivity of sugar beet root crops-to-corn for silage was 41.6 and 48.6 t/ hectare. Higher yield of sugar beet roots-to-clover and sugar beet root crops-to-corn for silage (51.7 and 50.7 t/ hectare, respectively) was obtained by the joint application of manure and mineral fertilizers at the rate of 30 t/ hectare + N60P135K30. The sugar content in root crops depended on the dosage of fertilizer application and sugar beet pre preceding crops. In the mineral fertilizer system a significant decrease in the sugar content of root crops by 0.3-0.5% compared to the check variant was of sugar beet root crops-to-clover and by 0.2-0.4% of sugar beet root crops-to-corn for silage. In the organic fertilizer system the application of 60 t/ ha of manure for sugar beet reduced the sugar content by 0.4% and the sugar content of root crops-to-corn for silage decreased by 0.2%. For the joint application of organic and mineral fertilizers (30 t/ hectare + N60P135K30) the decrease in the sugar content of root crops-to-clover was 0.4% and the decrease in the sugar content of root crops-to-corn for silage was 0.3%. In both parts of the crop rotation the higher productivity of sugar beet in the podzolized chernozem of Right-bank Forest-Steppe was obtained after the joint application of manure and mineral fertilizers. For saturation of the crop rotation with manure at the rate of 9 t/ hectare and mineral fertilizers at the rate of N45P67.5K36 with a direct application of 30 t/ hectare of manure + N60P135K30 the sugar yield of root crops-to-clover was 9.07 t/ hectare and the sugar yield of root crops-to-corn for silage was 8.84 t/ hectare. | ||
