The main ways of resource saving in the cultivation of spring wheat in the western part of the Republic of Kalmykia

The article presents the results of four-year researches concerning the optimal conditions of spring wheat growing on light-chestnut (brown) soils of the east part of Kalmykia. There has been established the promising technological range of water and mineral supply, and there have been determined the spring wheat varieties with a great response on these intensification factors. The article gives the characteristics of climatic conditions of the region, the methods of conducting of field experiments and the scheme of fulfilling of field trials. The results of the experimental and theoretical researches of the resource-saving technology of spring wheat cultivation with the optimization of irrigation regime and mineral supply have been considered. The resource-saving technology of spring wheat cultivation on slightly saline light-chestnut soils has been developed, that allows decreasing specific consumption of irrigational water on 10-30% and allows yielding 6 t/ha of grain with 15.9-17.0% of protein and 39.2-41.5% of raw gluten
