Results of economically valuable indicators of varieties of children's hornous in the selection nursery in the conditions of the Smolensk region

Abstract

The article presents the results of a test of new varietal species of baby eagles in a breeding nursery in 2018 - 2019. The options for the first and second year of use were evaluated. The purpose of these studies was to identify the most valuable economic traits of new highly productive varieties for use in further work. Weather and climatic conditions were generally favorable for the wintering and development of plants of horned calves in the spring and summer. During field trials, it was found that in terms of green mass yields in the total over two years of use, the E-25 variant stood out (+ 30.5% to Smolensky 1 standard). Over the entire period of testing, he showed a high and stable increase. It was slightly lower with the E-49 varietomer (+ 24.2%), which showed higher yields in the first year of use than in the second. They also stood out by the yield of air-dry matter (+ 21.4% and + 31.45%, respectively). Such productivity of the plant of horned lamb was shown in the conditions of sowing on slightly acidic loamy soil with a low content of humus, mobile potassium and a high content of phosphorus.
