Brassica napus is one of the important oilseed crops in temperate regions and has a relatively wide range of climate adaptation. The rapeseed contains 25% to 55% oil, 18% to 24% protein and 12% to 20% skin.
Due to the amount of oil present in rapeseed seeds, it is cultivated for successive centuries. The plant was originally grown on the eastern coast of the Mediterranean, although its use has a long history. There is evidence that this plant and its oil were used in India 5 years BC. In Central Europe the plant has been cultivated since the 14th century. Since the 17th century, the plant has been cultivated on a large scale in Europe.
Features of Rapeseed Planting
Rapeseed has high yield potential and has high seed oil content (40% -45%) among oilseeds and can be effective in reducing the amount of external dependence on vegetable oil.
Having spring, winter and intermediate types allows cultivation of this plant in different climatic conditions
Rapeseed can be alternated with wheat and barley crops, reducing disease, pests and weeds and increasing grain yield of these crops.
Autumn gardening requires less irrigation and the possibility of using autumn and winter rainfall.
The growing season of rapeseed is different from other oilseeds and when the capacity of the oilseeds is empty the plant is harvested.
Due to the favorable plant residues, in addition to having a positive effect on soil organic matter, it is also effective in providing the forage needed by ranchers.
It can play an important role in the development of the beekeeping industry.
In areas that have problems with irrigation in spring due to water limitation and simultaneous irrigation of spring crops with the latest water, canola cultivation, especially early cultivars, can solve this problem (central part of Saveh city).
