Abstract
A significant part of the livestock feed in Siberia is obtained from yellow melilot (Melilotus officinalis Pall.) – a perennial legume crop. In addition to its nutritional benefits, melilot is valuable as a source of biological nitrogen in soil and has phytosanitary qualities. To increase the productivity of the crop with considerate consumption of moisture resources, it was proposed to use inoculation of melilot seeds with the nodule bacteria compound – “Rizotorfin”. It was proved in a field experiment that the “Rizotorfin” treatment of melilot seeds contributes to a more reasonable expenditure of soil moisture, the evapotranspiration coefficient characterizing the average moisture consumption per 1 ton of crop’s green mass is reduced by 0.7 relative to the control variant plants. The root system develops better, the morphometric parameters of the experimental plants are 25-31% higher than those of plants not treated with “Rizotorfin”. The green mass yield of the experimental plants is 28-33% higher than in the control variant.
Highlights
In solving the problems of modern agriculture that are associated with a high anthropogenic load on ecosystems, it is necessary to use biological approaches that increase the productivity of agricultural plants and the preservation and restoration of soil fertility
Yellow melilot (Melilotus officinalis Pall.), which has a number of positive qualities, is of particular importance
In order to increase the productivity of fodder crop rotation and the reproduction of soil fertility, an experiment was conducted of studying the effect of inoculation of yellow melilot seeds with the “Rizotorfin” product on the moisture consumption and green mass yield
