In the food industry, rye is used for bread baking. It is also used as an ingredient of animal feed, although it has an increased content of anti-nutritive substances. It is rich in carbohydrates, especially starch, thus it can be used as the raw material for alcohol production.
Rye is a popular crop on poorer soils due to the low soil and climatic requirements (it is highly resistant to frost). Other advantages of rye include: cost-effective water management, low sensitivity to acidification of the soil, and well-developed root system, making rye the least sensitive to nutrients deficiency.
This apparent "self-sufficiency" of rye often results in an extensive technology of its cultivation, giving rise to low grain yields - an average of approx. 2.5 t/ha.
However, in large farms, with appropriately selected varieties (hybrids bring higher yields then population varieties) and with proper agricultural techniques, yields reach from 7 t/ha up to nearly 10 t/ha, depending on the class of soil and the amount of precipitation during the season.
Doses of fertilisers containing phosphorus and potassium must be selected according to soil fertility and size of the expected yield. Nitrogen must be used with caution, as its too high availability increases protein content in the grain, but also a deterioration of all quality parameters of grains is observed, and in particular the fodder quality of protein. The increase in protein content in the grain of rye by more than 11% results in the deterioration of baking performance of flour. To obtain high yield of grain, rye needs magnesium and sulphur, as well as trace elements: copper (MIKROVIT COPPER or MIKROCHELAT Cu-15), molybdenum (MIKROVIT MOLYBDENUM) and zinc (MIKROVIT ZINC or MIKROCHELAT Zn-15). Therefore, even in a very cost-effective technology of rye cultivation, it is necessary to perform foliar feeding with trace elements containing fertiliser at least twice (PLONVIT CEREALS), while in an intensive cultivation it is recommended to implement an appropriate foliar feeding programme.
Foliar feeding of crops with suitable nutrients (PLONVIT fertilisers) and promoting the growth of their natural resistance (OPTYSIL, TYTANIT biostimulants) improve proper crop development, health, and resistance to stress. All these treatments discussed in further tabs, significantly impact the increase in yield and its good quality properties.
