Post Harvesting

Postharvesting :

After harvesting the crop bundles are made and sacked them in sun for 7 to 8 days. Threshing is done by beating the pods with wooden sticks or by trampling the plants by bullocks. Seeds are separated by winnowing, with the help of natural air currents but the wind velocity should not be very high as the seeds, being very small, are blown with the air.

Storage:
Store the produce after its moisture content is about 8 per cent approximately.

Processing and utilization:
Mustard is usually used as edible oil, as condiment, as medicine and for seasoning pickles. Rape oil is used in the manufacture of greases. Oil cake is used for feeding cattle and manures. The oil cake contains 4-5% Nitrogen. Oil content of rape seed-mustard varies from 30-48 per cent.
