A common element of efficient seed production-marketing systems is seed storage. Preservation of the storage system is always required if you want to keep seeds for a prolonged duration, say from 6 months to ten years. The more negatively impacted by temperatures they are, the more moisture-rich the seed is. For seeds to be viable, proper storage and transportation are crucial. So, the main question is what is the ideal temperature and relative humidity range for seed cold storage?
If dealt with harshly, big vegetable seeds like crops such as corn, beans, and beans are vulnerable to mechanical harm. Avoid throwing or dropping the bags when loading or unpacking these crops to avoid damaging the root systems and embryos. It has been demonstrated that poor handling greatly reduces germination or weakens seedling vigor. Reduce seed damage when applying fungicides, inoculums, or other chemicals to the seeds of these plants. We are going to talk in detail about “What Is The Ideal Temperature And Relative Humidity Range For Seed Cold Storage?”. Keep reading to learn everything else about it.
The Storage Type of the Seeds in the Cold Storage Solutions
Because of the gradient in vapor pressure—where the moisture flows from high to lower vapour pressure—seeds are able to collect moisture from the air. Moreover, insect activity ceases at moisture levels equivalent to or below 35 percent relative humidity, while fungal activity is suppressed at levels below 65 to 70 percent.
Well-dried, low-moisture seedlings are kept in moisture-proof jars throughout storage since seed moisture rises, especially in enclosed storage. Lower seed viability during storage is caused by higher oxygen levels. A dehumidifier is applied to regulate humidity in open warehousing, while moisture-proof containers are employed at low temperatures to preserve seeds from high humidity.
Many vegetable seeds can be kept for an entire year without significantly reducing germination percentage or seedling vigor. Vegetable seeds’ shelf lives can be impacted by storage temperature and humidity levels. The seed’s coat and plant embryos can both be protected from harm by handling seeds carefully.

Storage of Seeds Temporarily
To preserve the quality and survival of the seed, it must be treated and stored carefully from the time it is delivered to the farm and when it is planted (within six months). When feasible, save seeds in their original, unopened packaging from the seed provider or seed firm. Consider putting goods that have been opened in a container with a sealed container lid, like a can jar or sealed plastic bin. Suppose that after a seed packaging is unsealed, the seeds’ self-life will shorten.
Seed should, whenever feasible, be planted in the same year that it was provided or purchased. But, on occasion, producers want to carry over seed and plant it in a subsequent season because it was not utilized during the year for which it was planned. Vegetable seeds can typically be stored for a year without noticeably reducing their germination percentage or seedling vigor. 3 To improve consistency, the expert advises using every seed within two years from the date of purchase. Before the seeds are planted, it is advised that the reproduction rate of the seed be checked at a facility authorized by the International Seed Testing Association (ISTA) at least every year.
The Ideal Temperature and Relative Humidity Range for Seed Cold Storage
Seed germination and vigor will be decreased by high temperatures and high humidity levels. Avoid keeping seeds in regions with high temperatures (over 70°F) or high humidity levels (above 60%). Seeds should be stored at a temperature of 35 to 40 °F and a relative humidity of under 40%. In most freezers, the temperature stays around 40°F, although the relative humidity is considerable. To maintain low moisture levels, seeds should indeed be retained in containers with tight seals and kept in freezers.
Use primed seeds during the current planting season if you buy them because they don’t store well. It is challenging to sow pelleted seeds because significant changes in relative moisture can affect the pellet’s integrity. stored pelleted seed
