Harvesting

postharvest-harvestingHarvesting is the process of collecting the mature rice crop from the field. Paddy harvesting activities include reaping, stacking, handling, threshing, cleaning, and hauling. These can be done individually or a combine harvester can be used to perform the operations simultaneously.

It is important to apply good harvesting methods to be able to maximize grain yield, and minimize grain damage and quality deterioration.


Harvesting systems

Harvesting systems

Harvesting systems vary depending on location or region, and can be done using a wide variety of traditional, semi-mechanical, and mechanical tools.

Harvesting costs

Harvesting costs

It is useful to evaluate the harvesting cost of paddy since it can make up a significant portion of the production cost of rice.

Reaping

Reaping

Reaping or cutting is the first operation in harvesting. Depending on the crop's condition, and availability of labor or machinery, cutting can be done either manually or mechanically.

Threshing

Threshing

Threshing is the process of separating the grain from the straw. It can be either done by hand, by using a treadle thresher or mechanized.

Measuring moisture content

Measuring moisture content

Different moisture contents are required per postproduction operation. These should be followed to ensure good quality of paddy.

Cleaning

Cleaning

Grain cleaning will improve the drying, the storability of grain, reduce dockage at time of milling, and improve milling output and quality; while, seed cleaning will reduce damage by disease, and improve yields.

Combine harvesting

Combine harvesting

Combine harvesting combines several operations into one: cutting the crop, feeding it into threshing mechanism, threshing, cleaning, and discharging rain into a bulk wagon or directly into a bags.
