The results of research work of a prototype of a specialized seed drill for joint crops of forage crops

Abstract

The article presents the results of research in 2017 and 2018 of the work of a prototype of a special seed drill based on Vega-8 Profi for joint sowing of grain and leguminous forage crops. The studies were carried out under the production conditions of two experimental farms - the Institute of the Northeast of the National Academy of Agrarian Sciences of Ukraine in Kharkiv (2017) and Sumy (2018) regions. The studies, which were carried out in accordance with the developed program and methodology, determined the quality indicators of the seeder, the effect of joint sowing of corn and soybeans on the yield of silage mass, as well as the effect of the obtained silage mass on the productivity of cows. The value of joint crops lies in the effective use of land, as well as a better feed composition. The most effective joint crops of forage crops with legumes, which not only enrich the soil with nitrogen, which is formed on the roots of legumes, but also increase the amount of protein and protein in the feed unit. In addition to determining the advantages and positive aspects in the work of the prototype of the planter, there were recorded failures and shortcomings in the work of the planter, which became the basis for further improvement of its design.Summarizing the results of two-year studies of the work of the planter showed that joint sowing of corn and soybeans provides the yield of silage by 30% higher than when sowing only corn. In accordance with the research program, in 2018, the effect of silage mass of joint crops on cow productivity was studied. The method of economic accounting was determined milk yield and its quality, provided that in the diet of cows was a silo of joint crops of corn and soybeans, as well as weight gain during fattening of heifers with silage from compatible crops. Feeding the cows with the obtained silage provided an increase in milk yield and milk fat content and weight gain in fattening heifers compared with only corn silage.
