Abstract
Relevance. Breeding work is aimed at creating varieties with high yields of green and dry mass, with improved feed qualities. The paper presents data on the influence of the multi-axis use of the Pstаhyrostachys juncea on the formation of the feed mass in the nursery of the source material.
Methods. The work was carried out in the nursery of the source material of the 2015 sowing year in accordance with the methodological guidelines for the selection of fodder crops and the methodology of the State Commission for Variety Testing of Agricultural Crops on 26 cultivars (K1–K26) of the Pstаhyrostachys juncea for 2019–2021. Statistical data processing — using the Snedecor (2004) and B.A. Dospekhov (2013) application software package in Excel (2010, USA).
Results. The influence of the hydrothermal regime on the forage productivity of samples by month was noted at the beginning of the growing season (in April) with a correlation coefficient of 0.74–0.85, in May — from 0.79–0.83. A significant increase in the yield of green mass in comparison with the Manchaara standard was obtained in K1–K3, K5–K7, K9, K11–K14, K18, dry matter — K2. According to the complex of indicators of feed productivity, a reliable increase was obtained in the K2 sample. It was found that when taking into account feed productivity from the first mowing period to the fourth, a decrease in green mass occurs in all samples. Since 2019, with the annual threefold mowing of samples, there has been a decrease in the productivity of the green mass.
