What is Post-Harvest Management?

Post-Harvest Management refers to all activities carried out after harvesting agricultural produce, including cleaning, sorting, grading, drying, storage, packaging, transportation, and marketing.

Its main objective is to maintain quality, reduce physical and biological losses, increase shelf life, and preserve the market value of agricultural products. Post-harvest requirements vary considerably between commodities.

Common Causes of Post-Harvest Losses

Post-harvest losses can occur because of mechanical damage, improper harvesting, excessive moisture, insects, rodents, microorganisms, unsuitable temperature, poor packaging, and improper storage.

Signs of post-harvest deterioration may include bruising, rotting, mold growth, discoloration, weight loss, insect infestation, and quality deterioration.

Harvesting the crop at the appropriate maturity stage is one of the first important steps in reducing these losses.

Storage & Handling Requirements

Grains and other dry commodities generally require proper drying before storage, with the appropriate moisture level depending on the commodity and storage system.

Fruits and vegetables require careful handling because bruising and temperature-related deterioration can significantly reduce quality.

Damaged produce should be separated, and suitable storage temperature, humidity, ventilation, packaging, and hygiene should be maintained according to the commodity.

Practical Post-Harvest Management

Practical post-harvest management should follow a systematic sequence of harvesting, cleaning, sorting, grading, drying or cooling where required, packaging, storage, and transportation.

Storage facilities should be clean, dry, well-maintained, and regularly monitored for pests.

Farmers should also maintain records of harvested quantities, storage losses, transportation expenses, selling prices, and final sales. This helps determine where post-harvest losses occur and how they can be reduced in future production cycles.
