Soil water regime, yield and grain quality of spring wheat using the direct sowing technology in the steppe zone of Altai Krai

Abstract

The paper presents data on the influence of the direct sowing technology on the soil water regime, the yield and the grain quality of the spring wheat in the steppe zone of Altai Krai. The results showed that 2009 was the best year for the spring wheat yield; 2012, 2014 and 2015 were characterized by the minimum values of the soil moisture content and the spring wheat yield. However, there was the highest amount of gluten in grains during these years. The correlation between the yield and the water accumulation in the meter soil layer for the autumn-spring period was the highest, R=0.83. This can be taken into account in the direct sowing technology implementation in the spring soft wheat production.
