Abstract
The article presents the results of research on five winter wheat varieties (Albatross Odesskiy (st), Selyanka, Kuyalnik, Victoria Odesskaya, Ermak) conducted on southern chernozem soil during four years with different weather conditions over the growing season. The studies were performed in a crop rotation and the winter wheat was cultivated after three predecessors: 1) black fallow, 2) maize for silage and 3) winter wheat. Winter wheat varieties were sown on two backgrounds - natural background of the predecessor (without fertilizers) and with mineral fertilizer application before sowing and as top dressing. Data are presented on the yield of winter wheat depending on predecessor, fertilizing background, biological characteristics of the variety and weather conditions prevailing during the cultivation years. The influence of the studied factors on the total water consumption and the coefficient of water consumption by wheat varieties was determined. It was established that in the Steppe of Ukraine, the highest grain yield is obtained after black fallow. The yield is also quite high after maize and winter wheat, especially in the years of favorable moisture supply and also when optimizing plant nutrition. The reserves of soil moisture and precipitation during the growing season are also effectively used when winter wheat is sown after fallow and with a significant advantage when optimizing the nutrition background of the plants and using the most productive varieties for the area. The introduction of the developed technological elements and the choice of productive varieties mostly adapted to the area conditions will significantly increase the gross grain harvest of winter wheat.| Reference Key |
