Agrobiological assessment of collection varieties of paiza (Echinochloa Frumentacea) in the conditions of the Lower Volga region

Abstract

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
