The water regime and water requirements for spring wheat on groups of ripeness in the southern forest–steppe of Western Siberia

Water was essential for plant life, as well as an essential element of soil fertility. Plants need water manifested itself in the first days of life. The process of germination begins only when they swell, that was, to absorb a certain amount of water. Studies of several authors found that the number of different plants from 25 to 150% by weight of dry seeds. Spring wheat during the growing season, on average consumes 300–400 mm of productive moisture. The coefficient of water consumption or water flow to create 1 ton of grain in the region of 150–170 mm. In this experiment, the used of a comprehensive application of chemicals contributed to a significant reduction of water consumption rate with respect to the culture of control by an average of 38 mm / m or 1.4 times, primarily by reducing the contamination of crops and increasing yields of grain. When forming technologies of cultivation varieties with different terms of spring wheat ripening there was a significant lack of information about their resistance to adverse environmental factors and responsiveness to the intensification means. Studies on the reaction of varieties to the intensification of funds in the region were limited, and the newly created varieties was virtually absent. The main reason for the low volatile yields of spring wheat in forest–steppe of Western Siberia should recognize insufficient hydration during the year (280–350 mm). The general lack of rainfall was compounded by their extreme instability and uneven precipitation. The decisive role played by the crop than the total amount of precipitation and the favorable distribution during the growing season according to the biological characteristics of varieties of spring wheat. To obtain high and stable yields of spring wheat was necessary to be familiar with the requirements of the culture to heat, moisture, nutrients, and soil
