HARVESTED THE CROP
AT THE RIGHT TIME.

Timely reaping and threshing ensures high-quality rice that leads to high market value and consumer acceptance. Harvesting too early results in immature grains with <1 to 1.5% harvest losses, and leads to low milling recovery of as low as 53%.

Harvesting too late leads to grain-shattering with > 3% (if manual) harvest losses. This results in low head rice recovery as low as 32% (manual) or 38% (mechanized).

KEY CHECK 9: DRIED, CLEANED, AND STORED GRAINS PROPERLY.

 

ASSESSMENT OF KEY CHECK

Palay is harvested when most of the grains are golden yellow:

  • 85-90% if manual harvesting
  • 90-95% if using combine harvester

Palay is threshed not later than one day after harvest during WS or two days during DS.

RECOMMENDATIONS TO ACHIEVE KEY CHECK

1. Drain field 1-2 weeks before the expected date of harvesting:

  • to attain uniform maturity and ripening
  • to prevent wetting of the grains during harvesting
  • for easy operation in the field

2. Harvest at the right maturity, when 85-90% (manual) or 90-95% (if using combine harvester) of the grains are golden yellow.

3. Harvest at the right grain moisture content (MC).

Use grain moisture meter when available.

18-21% (typical MC for DS)

 

20-25% (typical MC for WS)

 

4. After manual harvesting, thresh palay not later than one (WS) or two (DS) days.

  • Avoid piling the harvested crop in the field for more than a day to prevent heat buildup which leads to grain discoloration and low-quality milled rice.
  • Avoid threshing dripping-wet palay using a mechanical thresher to prevent losses from poor grain-cleaning and separation.
  • Observe the recommended threshing drum speed (800rpm for most engine driven threshers) to prevent grain damage. Faster speed may increase capacity but will also incur more blower and separation losses.
