Field peas are successfully grown only in those regions with a cool growing season, in fact, they will withstand quite heavy frosts. High temperatures accompanied by high relative humidity are decidedly injurious. Excellent crops are grown at 7, 000 to 8, 000 feet in the San Luis Valley of Colorado. They do well on most types of soil..
