Twenty-four varieties of peppers were grown at the Horticulture Research Center (HRC) outside of Fort Collins, Colorado during the 2004 growing season. Transplants were started in the greenhouse on April 1st. Seeds were planted into 72-cell trays filled with Sunshine No. 3 brand soil mix and topped with vermiculite to aid in keeping the seeds moist. Seedlings were fertilized once a week with fish emulsion fertilizer fed through an injector. An average of 20 plants of each variety were transplanted at the HRC on May 26th into black plastic mulch on beds with 30″ centers, in a double row at 18″ in-row spacing with one line of drip tape. Plastic hoops were used to support row cover from transplanting time until mid-July.

Unfortunately we were hit with a severe golf-ball sized hail storm on August 10, 2004. That storm plus a cool season lended to poor pepper production (see our Study Area web page for more weather information). Therefore we are not reporting yield data per plant for severely hail damaged varieties, however average weight per pepper, photos, and comments for each of the varieties are below. Yield data is available for varieties that had negligible hail damage, although again, keep in mind the unusually cool season. We will continue with pepper variety trials in 2005.
