Abstract

This article addressed effective agronomic practices used to cultivate promising varieties of desert forage plants suitable for soil-climatic conditions in order to improve the condition and increase the productivity of degraded desert pastures. The results of field research on the selection, collection, reproduction of seeds of perennial forage plant species with high productivity, resistant to drought and saline soils in the desert, and the restoration of the flora of degraded areas were also widely covered. The results of phenological observations showed that the highest germination and perfect seed count among desert forage crops was observed in kochia and agropyron, accordingly, was 31-32 seed germination and 60-65 perfect seed number, and seed purity and weight, agropyron crop also gave the highest results. The purity of seeds for agropyron crop was 62%, the smallest indicator referenced to haloxylon, accounted for 30%.

Highlights

  • Around the world, scientific researches are being carried out in the field of improving the ecological condition of pastures degraded and low-yielding sandy desert soils, and the cultivation of food crops [1, 8]

  • According to the results of phenological observations (Table 1), the highest germination and perfect seed count among desert forage crops was observed in kochia and agropyron, and the average was 31-32 seed germination and 60-65 perfect seed number

  • Widespread use of forage crops such as sorghum, krascheninnikovia, kochia, haloxylon, agropyron in year-round use in desert pastures: the research results highly recommended to sow the seeds of desert forage plants, tailwort 7 kg/ha, sorghum 9 kg/ha, krascheninnikovia 6 kg/ha, saxaul 5-6 kg/ha, kochia 3-4 kg/ha, agropyron 3-4 kg

Summary

Introduction

Around the world, scientific researches are being carried out in the field of improving the ecological condition of pastures degraded and low-yielding sandy desert soils, and the cultivation of food crops [1, 8]. In this regard, analysis of germination, growth, normal development of seeds of these crops, accumulation of nutrient mass and seed production is very important, in order to develop agro-technological measures the cultivation of desert fodder crops
