After harvesting rice seeds and planting for approximately 8 months, some farmers failed to properly manage the storage of their seeds. This negligence led to several issues such as high moisture content, rat infestations, and seed mixing, all of which significantly reduced rice production quality and yield. As a result, it is crucial for farmers to implement proper storage techniques after the harvest to ensure seed viability and long-term productivity.
One of the most critical factors affecting seed longevity is moisture content. When storing rice seeds, it is essential to strictly control their moisture levels—japonica rice should be below 13%, while hybrid rice must remain under 12%. A simple way to check the moisture level is by taking a small handful of seeds and biting them with your teeth. If they make a crisp, sharp sound, the seeds are dry and suitable for storage.
In addition to controlling moisture, good storage conditions are vital. Seeds should never be stored near chemicals, fertilizers, oils, or other substances that may release moisture, emit fumes, or cause corrosion. The ideal storage environment is a cool, dry warehouse with temperatures ranging from 5°C to 20°C and adequate ventilation to prevent dampness and mold growth.
Proper storage methods also play a key role in maintaining seed quality. Many farmers store seeds in bulk, in bags, silos, cabinets, barrels, or tanks. It is recommended to use different types of containers for various seed varieties and to hang them in a well-ventilated and dry area. This helps maintain seed integrity and prevents cross-contamination.
Preventing mixed storage is another important step. Each seed bag should have clear labels both inside and outside, specifying the variety name, source, quantity, and purity. When multiple varieties are stored together, they should be kept at a safe distance to avoid confusion. Additionally, care must be taken to avoid tearing the seed bags, as this can lead to mixing and loss of quality.
Finally, consistent management during storage is necessary. Farmers should regularly inspect the seeds, ensure proper ventilation, and monitor temperature and humidity levels to prevent mold and spoilage. Before storage, any existing insect holes should be sealed, and rat entry points should be blocked. For seeds stored in cloth bags, placing cedar branches or thorny materials around the bags can help deter rodents.
By following these steps, farmers can significantly improve the quality and longevity of their rice seeds, ensuring better yields and more sustainable farming practices.
