THE METHODS OF PRODUCTIVITY INCREASE OF WINTER SOFT WHEAT IN DRY CONDITIONS OF NIZHNY DON

The present growth stimulators and micro fertilizers (chelating agents) are an efficient method to create favorable conditions for the growth and development of winter wheat. Their use is of good effect on the growth and development of winter wheat till its maturity. The most increase of productivity (0.34 t/ha) has been obtained in the variants with the use of micro fertilizer ‘Nutrivant Universalny’ together with an anti-stress stimulator ‘Aminokat’ during the tillering period, while the processing of seeds with ‘Raykat Start’ together with the disinfection; in the variants with the use of the nutritional system ‘Raykat Razvitie’+’Raykat Final’ and ‘Mikrokat Start’+’Mikrokat Final’ with 0.39 and 0.36 t/ha of productivity respectively. The variety ‘Yuka’ produced the largest increase of productivity (0.96 and 0.89 t/ha) in the variants with the use of ‘Aminokat’ and ‘Nutrivant Universalny’ together with ‘Aminokat’ during the tillering period while processing of seeds with ‘Raykat Start’ together with the disinfection. It has been determined that to increase the productivity and kernel quality of winter soft wheat variety ‘Grom’ it’s recommended to process the plants with ‘Nutrivant Universalny’ together with ‘Aminokat’ during the tillering period while processing of seeds with ‘Raykat Start’ together with the disinfection or to use the nutritional system ‘Raykat Razvitie’ in the period of tillering + ’Raykat Final’ in the period of wax maturing. For the variety ‘Yuka’ it’s recommended to process the plants with ‘Nutrivant Universalny’ together with ‘Aminokat’ during the tillering period or to use to use the nutritional system ‘Mikrokat Start’ in the period of tillering + Mikrokat’ in the period of wax maturing
