Certified wheat seed is different from other seed because it is subjected to rigorous inspection and testing by government agencies.
Some farmers, however, try to save harvested seed for later planting seasons in order to save money on fresh seed. This method poses greater risks of varietal impurity, poor seed germination, diseased seed and volunteer crops and weeds because the saved seed is removed from the original certified seed variety.
Tested certified seed varieties show they are better than saved seed in yield, quality and test weight.
Certified seeds like Syngenta’s AgriPro brand are able to ensure genetic purity, smoother plantability, seedling vigor, improved germination and emergence.
