INFLUENCE OF CEREALS AND LEGUMES FORAGE CROPS TO INCREASE PASTURE PRODUCTIVITY

Abstract

This article presents the results of a study of the productivity of polyspecies agrophytocenoses to improve the condition of pastures in the Kostanay region. Forage crops in the mixture were selected according to the climatic conditions of this region, which are more resistant to winter hardiness for long-term use of pastures by farm animals. Describes the research methodology and results of field experiments with cereal and legume mixtures aimed at increasing pasture productivity. During the growing season, from May to August 2024, meteorological data were collected, including average monthly precipitation and air temperature. Agrochemical analyses of the soil were also conducted in the experimental variants where the humus content was from 3.69 % to 4.47 %. The study took into account such indicators as the growth ahd development of cereal-legume grass mixtures, which were determined by calculating the density and measuring the height of each plant by crop varieties. To assess the productivity of grass mixtures, mowing, weighing and drying of sheaves to an air-dry state by species was carried out. The results showed that the highest productivity is observed in a mixture of cereal and legume crops, namely in the wheatgrass-alfalfa-brome variant. The results of the study were influenced by the weather conditions of the region.
