Which agricultural practice is missing from the list: Irrigation, Removal of weeds, Preparation of soil, Storage of food grains, Sowing, Adding manure and fertilizers?

The missing agricultural practice is harvesting—the critical stage where mature crops are cut, gathered, and prepared for threshing and storage.

Harvesting represents the culmination of months of agricultural effort and must be timed precisely. Harvesting too early results in immature grains with poor quality and lower yields, while delayed harvesting can lead to grain shattering, pest damage, bird attacks, and quality deterioration from weather exposure.

Modern harvesting involves either manual methods using sickles and scythes for small farms, or mechanized approaches using combine harvesters for large-scale operations. The harvested crop then undergoes threshing (separating grains from stalks) and winnowing (removing chaff) before proceeding to the drying and storage stages already mentioned in the list.

Proper harvesting techniques minimize grain damage, reduce losses, and ensure maximum recovery of the cultivated crop. This makes harvesting an indispensable component of the complete crop production cycle from field preparation through final storage.
