The influence of use systems on the productivity of shrubephemeral desert pastures and the preservation of herbage

Abstract

The article is devoted to the urgent problem of developing a scientifically based organization and use of distant pastures in the south of Kazakhstan. It has been found that the composition and diversity of pasture grasses have significant effect on the forage value of the grass stand and ultimately affect the forage capacity of desert pastures. Grazing of farm animals should be carried out with an optimal load on pastures, that is, no more than 70% of the productivity of the pasture mass should be exploited. Due to the better preservation of various types of forage plants and pasture herbage in general with systematic use, the yield of pastures in the summer season was 6.15 c/ha, in other words it was higher by almost 1.0 c/ha of dry forage mass compared to unsystematic grazing (5.20 c/ha). All pasture plants exploited in early spring produced aftermath in 10–15 days and were well preserved from overexploitation and trampling.
