Late Harvesting Palay: How Many Days Can You Wait?
You cannot allow any days for late harvesting palay without losing yield. Harvesting even a few days past maturity causes grains to shatter and fall to the ground. For a one hectare direct seeded dry farm, you must harvest exactly when 85 to 90 percent of the grains turn golden yellow. Waiting longer makes the grains brittle and lowers your milling recovery.
"How many days late is allowed for harvesting?" Asked by a farmer with 1 hectare of Rice, Direct Seeded Dry (Palay) in Alcala, Pangasinan.
The Cost of Late Harvesting Palay
When you leave your crop in the field past its maturity date, you lose money. In fact, overripe grains easily detach from the panicle. This shattering causes more than 3 percent yield loss right in the field. Late harvesting palay also makes the grains brittle. Brittle grains break during milling, which drops your head rice recovery to as low as 32 percent for manual harvests.
Besides shattering, a delayed harvest exposes your crop to rats, birds, and weather damage. If a typhoon hits Pangasinan while your crop sits overripe, lodging will ruin the grains. Also, you lose germination potential if you plan to save some palay for rice seeds next season. Because of these risks, you must cut the crop as soon as it reaches maturity.
How to Tell When Your Crop Is Ready
Instead of counting exact days, you should look at the grains. Agriculturists say the ideal harvest time is 110 to 120 days after sowing for most direct seeded crops. However, the exact day depends on the rice varieties in the Philippines you planted. For example, early maturing types need about 110 days, while late maturing types take up to 136 days.
Agriculturists recommend checking the panicles visually. Your crop is ready for manual harvesting when 85 to 90 percent of the grains are golden yellow. If you rent a combine harvester for your hectare, wait until 90 to 95 percent of the grains turn yellow. Then, test the grain firmness. The grains should feel firm but not brittle when you squeeze them between your teeth.
| Harvest Method | Golden Yellow Grains | Moisture Content |
|---|---|---|
| Manual Harvesting | 85 to 90 percent | 20 to 25 percent |
| Combine Harvester | 90 to 95 percent | 20 to 25 percent |
Moisture Content and Field Preparation
Harvesting at the right moisture content prevents breakage. You should harvest when the moisture content is between 18 and 21 percent during the dry season. During the wet season, aim for 20 to 25 percent. If you do not have a moisture meter, you can bite a few grains. They should feel hard but not crack easily.
Preparing your field early makes the harvest much easier. First, you need to drain the water from your paddies. This helps the crop mature evenly across your entire hectare. Next, dry soil supports the weight of a combine harvester much better than mud.
Drain the field
Drain the water one to two weeks before your expected harvest date. This helps the crop mature evenly and makes walking in the field easier.
Adjust for soil type
If your Alcala farm has heavy clay soil, drain it 10 to 14 days early. For lighter sandy loam soils, 5 to 7 days is enough.
Adjust for the season
During the dry season, you can delay draining the field by an extra 5 to 10 days.
Delays after cutting the crop are just as bad as late harvesting palay. You must thresh the crop within one day during the wet season, or within two days during the dry season. Piling the harvested crop in the field causes heat buildup, which discolors the grains and lowers the palay price philippines buyers will pay.
