UNH Scientists Successfully Grow Onions Overwintered in Low Tunnels

As we get into the heart of a very cold winter, the demand for year-round produce is one thing that isn’t freezing over. Researchers with the New Hampshire Agricultural Experiment Station have developed an onion production model that is sustainable through the colder months, and will help farmers in more severe climates maintain productivity. The main components of the system are the low hanging tunnels that shelter the onion cultivars from the harsh conditions. Planted during the fall, these crops saw a survival rate between 65 and 100 percent. If growers are able to harvest and sell these onions during the winter, it would provide a great opportunity for direct-market sales. Learn more about the NHAES project below:
