A good (8 t/ha and more) winter wheat grain yield should be achieved by establishing a crop with at least 450 mature ears per m2 and 18 000 thousand grains per m2. The choice of variety and sowing timing are the most important tools for managing the development of winter wheat, and adequate plant nutrition is a prerequisite for a high yield. Varieties should be selected from among the well-tested varieties with high winter hardiness, low susceptibility to disease and high productivity in the country's climate. Winter wheat overwinters and produces better when well supplied with phosphorus and potassium, so all or a large part of the phosphorus and potassium application rate for the planned harvest should be applied before or at the time of sowing of the winter wheat. For winter wheat grown after good nitrogen-fixing pre-crops (bean crops), it is not necessary to apply nitrogen fertiliser in autumn. For cereals sown after other pre-crops, nitrogen rate of up to 20 kg/ha could be applied at sowing together with phosphorus and potassium in the form of complex fertilisers. In fields with low nitrogen content, autumn fertilisation with nitrogen rate (30 kg/ha) may be beneficial.
