In the arid conditions of the Lower Volga region, paiza is a promising forage crop. Due to the complex of biological and economically valuable signs and properties, the paiza has a direct relationship between the yield of green mass and precocity, on the one hand, and between the yield of this mass and tallness and foliage, on the other. This choice is also determined by its relative drought resistance and the ability to withstand extreme positive temperatures in arid climatic conditions of Russia without loss of yield and grain quality, which allows it to be grown in many regions of the Russian Federation. The article presents the results of the yield and nutritional value of aboveground biomass in the phase of milk ripeness. Keywords: PAIZA, SELECTION, VARIETY PATTERN, YIELD, ABOVEGROUND BIOMASS

As a result of two-year studies, a significant effect of granulated organic fertilizer "Greenex" on morphometric indicators and productivity of biomass and seeds of the studied crops was found. The use of fertilizer at a dose of 200 kg / ha proved to be the most effective. So, the pre-sowing application of this dose of fertilizer provided a reliable excess of indicators relative to the control on all variants of the experiment. To improve growth processes, the maximum effect was found in soybeans and grain sorghum. It was revealed that the increase in yield when using fertilizer compared to the non-fertilized control was 12.99-29.33% for crops.
