SUGAR BEET PRODUCTIVITY UNDER CONVENTIONAL AND ALTERNATIVE SYSTEM OF FERTILIZERS
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 6, Issue 6
Abstract
The purpose of the research is learning an efficiency of conventional and alternative systems of fertilizers in increasing sugar beet productivity. In process of investigation it was used field and laboratory methods with mathematical processing of the results. With the lack of the manure production, the application of N90P60K90 + 5 t/ha of winter wheat straw + green manure for sugar beet growing provided the productivity of roots - 63.7 t/ha, sugar content – 17.6%, sugar harvest – 11.2 t/ha. Due to application of winter wheat straw and green mass of white mustard, the yield of roots increased in comparison with the fond N90P60K90 per 6.4 t/ha, the sugar harvest – per 1.2 t/ha. An alternative system of fertilizers with using winter wheat straw, green mass of white mustard together with the optimal dose of fertilizers (N90P60K90) is quite effective in increasing sugar beet productivity. With its application, the yield of roots increased in comparison with the control without fertilizers – per 23.8 t/ha, the sugar harvest – per 4.1 t/ha. The alternative system of fertilizers was somewhat inferior in efficiency to the application of N90P60K90 + 40 t/ha of manure, which creates prospects for further improvement in the set of optimization of the doses of fertilizers.
