THE USE OF CHEMICAL AND BIOLOGICAL TECHNICS IN CROP FARMING TO INCREASE SPRING WHEAT YIELDS IN PRIURALYE OF THE REPUBLIC OF KAZAKHSTAN
The use of microbial preparations to increase the spring wheat yields in the dry-steppe zone of Kazakhstan Priuralye is considered in the article. The methods of basic treatment of fallow lands, i.e. mouldboard plowing and mouldboardless one, the use of nitrogen fertilizers, both separately and in combination with diazotrophs, and the application of herbicides in the phase of wheat crop layering have been studied. It is established that for effective development of waste lands, it is recommended to use the tillage system that includes summer and autumn soil treatment, consisting of sod disking and mouldboard plowing, pre-sowing application of nitrogen fertilizers, spring wheat seeds treatment with Rizoagrin microbial preparation and spraying the crops with the tank mixture of herbicides at the stage of layering. When using the system of summer-autumn fallow lands tillage with preliminary spraying of weed plants with a tank mix of herbicides only the pre-sowing application of nitrogen fertilizers is recommended.
