Spring wheat is a cold-season crop which is able to withstand frosts up to 10°С below freezing point. This crop has good tillering and good forming of crown root system. But, during grain formation, spring wheat suffers from high temperatures.
At the temperature of 38-40°С in 17 hours the plant will have respiration palsy and as a result bad grain formation. In this period it needs the top-dressing for drought resistance. The root system of spring wheat has physiological hypo activity and thus it is necessary to process seeds with 3,0?4,0% solution of “Riverm” before sowing.
The top-dressing is made with 2,0?4,0% solution of “Riverm” in the period from tillering to stem elongation (depending on the edaphic and climatic conditions and seeds state).
