The peculiarities of formation of grass and increase in green mass of Galega orientalis in the subtaiga zone of Omsk region

The purpose of the research is to establish the influence of agrometeorological conditions on the formation of grass stand and the dynamics of growth of green mass of galega orientalis during growing season. The object of research is galega orientalis, a variety of Gornoaltaisky 87. In the re- searches approved techniques of V.R. Vilyams All- Russia Research and Development Institute of Forages and Russian Agricultural Academy are used. Statistical treatment of information was per- formed according to B.A. Dospekhov. According to the results of the research, it has been established that from spring regrowth to the beginning of plant-ing, the intensity of the increase in green mass pro- ceeded at a slow rate of 20 kg/hectare a day. In the process of increase in the sums of effective tem- peratures above 5 °C and the amount of precipita- tion, the dynamics of growth of green mass in the first mowing increased. To obtain the maximum yield in the phase of stitching of 12.0 t/hectare, the first cutting should be carried out on 10...
