Harvesting and threshing
Usually rapeseed-mustard crops are harvested as soon as the pods turn yellowish and moisture content of the seed is around 40%. The crop should be harvested preferably in the morning hours, when the pods are slightly damp with night dew to minimize the shattering losses.
Bundles of the harvested plants are staked and dried in the sun for a few days. Threshing is done by the usual method of threshing by bullocks or running a tractor over the dried plants. Seeds are separated by winnowing. Moisture content of the seed must be less than 8% at the storage time.
Yield
Under normal conditions, rapeseed yields about 1.4-2.0 tonnes/ha of seed, while mustard may give 2.0-2.5 tonnes/ha.
