By this time, you may be expecting a record-breaking harvest of your hybrid rice. But even if you obtained a 30 percent yield advantage by planting PHB71 compared to your previous season’s harvest from an inbred or other hybrids, such yield advantage can be easily lost by postharvest losses. The following discussion thoroughly deals with minimizing such losses.
About 15 to 20 percent of our annual rice production is lost due to improper postharvest handling and processing. Postharvest losses can even reach 50 percent during the rainy season, especially in areas hit by typhoons. These losses are largely due to improper drying and storage. Our rice farmers toiled to produce every grain only to be lost when all we have to do is put it into our mouth. This is particularly disturbing in the context of a nation that has been perennially importing rice to feed its growing population. Reducing these losses will auger well to our seemingly unreachable quest for rice self sufficiency.
At near ideal situations, like in the International Rice Research Institute, rice grown to supply the rice allowance of its employees is harvested by track-laying combine harvesters. The paddy rice is immediately dried to 14 percent moisture content either by flatbed dryers or via continuous flow dryers for about 6-8 hours. After drying, the paddy is milled by a state of the art ricemill to produce quality polished rice ready for distribution just within 24 hours after harvest.
