AgroZAR - Rapeseed

Complex concentrated microfertilizer for foliar feeding of winter and spring rapeseed, mustard and for pre-sowing treatment of their seed material.

Rape is characterized by a high demand for boron (B), manganese (Mn) and molybdenum (Mo). But, in addition, it is increasingly being talked about the need for additional application of zinc (Zn) and copper (Cu) for intensive rapeseed cultivation technologies, especially on light or organically saturated soils.

Boron. The normal supply of boron in the autumn period plays a key role in the development of culture, because it is critically important for the normal development of the root system, the metabolism of carbohydrates and proteins, the increase of frost and winter resistance, the regulation of water exchange in tissues and the increase of resistance against diseases. In the flowering phase, sufficient supply of boron is necessary for the germination of pollen and the growth of pollen tubes, as well as for the formation of the appropriate number of seeds in pods, which is important for achieving high yields.

Manganese plays a key role in photosynthesis, nitrogen metabolism (reduction of nitrates and synthesis of amino acids), is a component of a number of enzymes involved in respiration, and activates important metabolic reactions in the plant. After all, manganese is a cofactor of more than 35 enzymes in plants. Lack of manganese directly affects photosynthesis, as a result of which the amount of soluble sugars in plants decreases, winter hardiness and accumulation of dry matter decrease, which, as a result, leads to a decrease in yield.

Zinc increases the winter hardiness and frost resistance of plants, as it affects the redistribution of sugars from the leaves to the root in the autumn period; increases the activity of tryptophan synthetase and stimulates the formation of the amino acid tryptophan, a precursor of auxin. Therefore, normal provision of plants with zinc contributes to the active development of the root system of young plants, increasing their ability to use moisture from the soil.

Copper has a positive effect on the energy of seed germination, nitrogen consumption by plants, increasing resistance to abiotic stresses, together with manganese increases the stability of cell walls and prevents wilting, reduces the risk of burns from nitrogen fertilization by KAS and other chemicals.
