Abstract (English):
The technology of cropping should vary depending on the climatic conditions of a particular region. In developing resource-saving technologies of spring wheat cultivation, we must remember that during the growing season in the Republic of Tatarstan every square centimeter of the soil surface gets a day 1 kcal of heat, the sum of positive temperatures above 10 C in the republic is 2100-2200º, annual rainfall is 450-460 mm of precipitation; an average yield of 2.5 tons of grain per 1 hectare per ton 180 mm of moisture is consumed. This misallocation of productive moisture mainly occurs due to violations of cultivation technology (soil preparation, planting dates, insufficient use of macro-and micronutrients, care for crops etc.). In this regard, during the spring wheat cultivation it is necessary to achieve a minimum of productive moisture evaporation from the soil, the source of precipitation , which would get pretty high yields even in the driest years .
