Factors of stabilization of production of grain of winter wheat in Right-bank forest-steppe region

Abstract

The purpose. To justify risks and opportunities of stable production of grain of winter wheat in state-of-the-art agrophytocenosis of Right-bank forest-steppe region. Methods. Analysis, synthesis, generalization, field experiment. Results. Influence of modern techniques upon productivity and quality of grain of winter wheat is probed at late seeding emergence. Expediency of use of postharvest plant residues in conditions of limited application of organic fertilizers is proved. Conclusions. Later seeding emergence of winter wheat in 70% of events is imminent after late predecessors because of excessively droughty and rainy September, and after early predecessors such probability makes 50%. Application of no-till-technique enables to decrease essentially term between sowing and sprouts and to prolong autumn vegetation. Optimization of existing systems of mineral nutrition with the use of crop residues, bacterization of seeds and microfertilizers, high quality grades positively influences productivity of grain and its quality.
