Harvesting operations for early and hybrid varieties of paddy, the principal Kharif crop, are underway across Jaunpur and neighbouring agricultural belts. Once the harvest leaves the field, growers encounter the critical task of preserving their grain stocks. Farmers typically sell a portion of their produce at the Minimum Support Price (MSP), while retaining a substantial quantity in domestic storage for consumption or future sale. Without meticulous storage measures, harvested grains face severe infestation risks from weevils and other destructive pests that can erase season-long farm earnings.
Moisture Management as the Primary Defense Line
Ensuring grain longevity requires thorough post-harvest drying before packaging. Deputy Project Director of ATMA, Dr. Ramesh Chandra Yadav, emphasizes that farmers must dry paddy thoroughly in the sun to bring moisture levels down to between 10 and 12 percent. Excess internal moisture provides an ideal breeding environment for weevils, fungal moulds, and other storage pathogens. Damp grain rapidly loses nutritional quality and physical integrity, resulting in steep market downgrades and avoidable monetary losses for farming families.
Subsidised Metallic Bins and Safe Fumigation
To reduce post-harvest losses, the agriculture department supplies storage bins (bakhari) and grain sacks at a 50 percent subsidy. Agricultural specialists urge growers to take advantage of these subsidised tools rather than using unsealed traditional enclosures. When storing grain inside metal containers, farmers should deploy zinc phosphide by tying the chemical securely inside a cotton cloth and placing it in the centre of the grain mass. The container lid should subsequently be sealed airtight with mud to prevent gas leakage and ensure complete insect eradication.
Stacking Protocol and Warehouse Disinfection
Growers who store grain in sacks must treat the bags with malathion before filling. When arranging the filled sacks inside the storage facility, stacks must remain at least 2 feet away from interior walls to block moisture seepage from damp masonry. Additionally, the storage room itself should be fumigated using zinc phosphide smoke to neutralise existing insect populations. Adopting these disciplined scientific methods enables farmers to maintain grain freshness into the following year, granting them the flexibility to release stock when market rates are optimal.
