EFFICIENCY OF THE METHODS INCREASING GRAIN PRODUCTIVITY OF DIFFERENT VARIETIES OF WINTER WHEAT IN NORTHERN STEPPES OF THE UKRAINE

Abstract

The paper deals with the assessment of the influence of predecessors and the level of mineral nutrition on grain productivity of the new varieties of winter wheat cultivated in northern Steppe of the Ukraine. It’s established that application of mineral fertilizers with further top dressing of young crops in the tillering stage ensures the maximum yield. With this nutrition regime the variety Skabnitsa demonstrates the highest yield of 7.30 per hectare. When winter wheat is planted after pea and sunflower more productive is the variety Pisanka with the yield of 4.76 and 4.15 tons per hectare.
