Heterologous seed storage is a crucial part of the grain harvest process. Unfortunately, many farmers suffer unnecessary losses due to improper storage practices. To ensure the quality and viability of seeds, it's essential to follow some key guidelines:
First, use durable, safe, moisture-resistant, and heat-insulated storage containers that are clean and free from pests. These containers should allow for good ventilation while also preventing rodent damage. It's best to store seeds in jars or other suitable containers rather than plastic bags. Plastic can trap moisture and gases produced during anaerobic respiration, such as alcohol and carbon dioxide, which can significantly reduce germination rates and even destroy seed viability.
Second, maintaining a dry storage environment is critical. Especially after recent rainfall, extra care should be taken. Seeds continue to undergo metabolic processes during storage, and their moisture content directly affects this activity. High moisture levels increase respiration, leading to heat buildup that can damage or even burn the seeds. Keeping seeds dry helps slow down respiration, suppress internal physiological activities, and inhibit microbial growth.
Third, since seeds can vary greatly in type and appearance, many look similar, making it difficult for farmers to distinguish them just by sight. Therefore, it's important to label containers clearly—both inside and outside—and store different types separately. Also, avoid mixing heterologous seeds with fertilizers or pesticides, as this can lead to contamination and lower germination rates.
Fourth, regular monitoring and maintenance are necessary for effective seed storage. Check temperature and humidity regularly, ensuring that storage temperatures stay below 25°C. Be vigilant about pests like mice and insects, and take immediate action if any issues are found. By staying proactive, you can protect your seeds and ensure better yields in the next planting season.
