The third part of rapeseed cultivation - rapeseed plant nutrition, flowering and podding stage, seed

Rapeseed needs more nutrients than wheat. But a large part of nutrients absorbed from the soil returns to the soil through rapeseed residues. The highest requirement and absorption of nitrogen from the soil occurs at the beginning of stem growth in rapeseed and reaches its peak in the late budding and early flowering stage, and then the need for nitrogen decreases, which indicates the appropriate time to use nitrogen fertilizer at the beginning of stem growth and the peak of budding. And before flowering. Rapeseed absorbs more sulfur from the soil than any other plant. Sulfur absorption by canola is 2 to 3 times compared to wheat. Rapeseed absorbs boron from the soil more than wheat, and in case of deficiency of this element, the yield of the crop decreases. In late cultivation, the efficiency of fertilizer use is low and decreases. It is better to plant early than to plant late and try to compensate for the delay in growth by using more fertilizer.
