After the winter rest period, the rapeseed plant regenerates the root system and creates a new rosette of leaves. During the spring growth, rapeseed forms a large organic mass and then it is necessary to bring the largest part of the total needs of plants for nitrogen and sulfur into the soil. The optimum nutrition of rapeseed with nitrogen and sulfur provides for better shaping of the pods and the number of seeds per pod, i.e. yield component.

The fertilization of rapeseed should be done before the vegetation starts in spring and at the beginning of the stem growth when nitrogen and sulfur fertilizers, such as ASN and CAN, can be used. The first feeding is done in the second half of February when the root of rapeseed is regenerated. It is necessary to apply 200 - 250 kg / ha of ASN or CAN. When the first buds emerge from the rosette, the second dressing can be done with150 - 200 kg / ha ASN or CAN or 200 - 250 kg / ha of PETROKEMIJas.

The optimum nutrition of rapeseed, in particular with nitrogen and sulfur, results in the largest possible number of buds, better pollination and growth of fruit, i.e. pods.
