मड़ाई और फटकाई

This Class 9 Agriculture topic from Crop Protection and Storage explains how harvested crops are processed to separate useful grains from stalks, husks, and other impurities. Students learn the purpose and basic methods of threshing, including beating, animal or machine-powered operations, and winnowing, which uses moving air to separate lighter chaff from heavier grains. The topic also highlights careful handling, cleanliness, safety, and the role of these steps in reducing post-harvest losses before storage.
