Here are some points you must keep in mind while harvesting the crop:
1. Mustard crop is harvested manually.
2. After harvesting, mustard should not be left in sunlight for a long time as the pods are destroyed by the sunlight.
3. Thresh the crop with the help of a thresher
4. After harvesting the mustard crop, use disc harrow to mix the remaining stubble in the fields as the stubble acts as green manure.
