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 35 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. Hawaii_corn 


Consistent daytime temps in the high 80s with evening temps never falling below 60 means no risk of freeze damage. This also results produces a tropical speedup phenomenon for faster turnaround times. In comparisons of the same seed planted in Puerto Rico and Hawaii on the same date in November, the Puerto Rican plot was almost two weeks ahead of the Hawaiian plot at harvest. The commute to Puerto Rico is shorter and less costly. Shipping from Puerto Rico to the Midwest is faster and less expensive. As a Commonwealth of the United States, Puerto Rico operates under Federal laws and agencies providing a regulatory framework familiar to companies from the US and around the world.
