Methods for using pastures in semi-desert zone of West Kazakhstan

Abstract

The research allowed one to prove the seasonal organization of pasture economy using the distant pasture. The studies were carried out in 2018-2021 in the semi-desert zone of Western Kazakhstan. The aim of the research is to study and select the best ways to use pastures for organizing measures for their rational management. The soil of the areas of unsystematic and seasonal grazing is light chestnut medium loamy. Driving pastures are located in the sands zone. In the summer period, an increase in the number and occurrence of valuable pasture plants Kochia prostrata, Agropyron desertorum, Festuca valesiaca, Leymus ramosus, Koeleria cristata was noted on seasonal pastures. On the distant site of sandy pastures, 23 plant species of different economic and botanical groups have been determined, and due to the natural conditions of sands in the phytocenosis, the occurrence of valuable plants in the forage ratio is high. By the middle of summer, in the area of seasonal and distant pastures, despite the loss of forbs from the vegetation composition and drying of cereals, the yield of green phytomass was 0.81-1.03 t/ha, which is 0.43-0.65 t/ha. In this work, it was concluded that to improve the efficiency of pasture resource management, it is important to use seasonal pastures with the inclusion of a distant site in pasture rotation, which is the scientific novelty of the research.
