Wheat is a cereal of relatively high water requirements. As a result, it produces lower yield in years with lower precipitation, particularly on light soils. At the same time, the excess of water during the grain formation and maturation periods leaves room for development of fungal diseases and lower the grain quality.
Winter wheat has high thermal requirements during its whole vegetation period. A sunny autumn increases frost resistance (in winter varieties). Depending on a variety, it can endure temperatures between -20ºC to even -25ºC, if under a snow cover.
To ensure abundant and high in quality yield, wheat requires appropriate fertilization and application of stimulants guaranteeing proper tillering and formation of larger number of ears and grains.
On average, with 1 tonne of grain and appropriate amount of straw, it absorbs: 28-30 kg of nitrogen (N), 12 kg of phosphorus (P2O5), 22 kg of potassium (K2O), 6 kg of calcium (CaO), 4 kg of magnesium (MgO), 3.5 kg of sulphur (S), or 9 kg when calculated in SO 3, 5.5 g of boron (B), 8.5 g of copper (Cu), 360 g of iron (Fe), 110 g of manganese (Mn), 0.7 g of molybdenum (Mo), and 70 g of zinc (Zn).
