Puerto_rico_cornIllinois Crop operates a winter farm in Puerto Rico, where the growing conditions are ideal due to the region’s warm climate, rich soil and drip irrigation system.

Illinois Crop has over 30 years of experience on the island. While not without its challenges Puerto Rico offers one of the best options for winter work for plant breeders and seed producers. The farm also supports other seed companies on the island by offering seed certification and phytosanitary inspections.

Further, the Puerto Rican south coast offers several advantages over other common winter-farm locations.
