Abstract:

Tillage technologies that promote resource-saving and increase in the yield of agricultural crops are being increasingly involved into the agriculture of arid territories of Russian Federation. Studies of the impact of new tillage on soil quality and yield in Russian Federation are necessary owing to the high soils and climate diversity. Yield enhancement of major crops – winter wheat and sunflower – have been observed in Russian Federation in recent years. During 2014–2019 in the south of the European part of Russian Federation (Rostov region), the effect of No-Till (NT) on soil quality and yield of field crops was studied. The studies were carried out over an area of 5,500 hectares in comparison with adjacent fields, where conventional tillage (CT) of soils with mould board plowing was used. The yield of sunflower and winter wheat depended significantly on the amount of precipitation during the growing season. In 2014–2017 the use of No-Till increased the yield of winter wheat by 26–114%, of sunflower – by 27–92% as compared with farms, where the conventional tillage of soil treatment was used. No-Till helped to save motor fuel, increase yields of agricultural crops and lower the cost of winter wheat and sunflower.
