The retail value of yellow and red bell peppers is usually three to five times higher than that of the green ones. However, colored bell pepper production in Alabama is presently limited because most growers do not wait the additional 3 to 6 days needed for marketable green pepper to develop color. Hence, drip-irrigated yellow `Admiral' and `Goldcoast' and red `Bell Star' and `Capsitrano' bell peppers were grown in single row and bare-ground, and harvested as needed between July and October 1997 at the 0/3 (green), 1/3 or 2/3 colored stages. The interaction variety × picking method was not signficant (P > 0.50). Early (9,136 kg/ha) and total (32,363 kg/ha) yields of green (0/3) peppers were significantly (P < 0.05) higher than those of the 1/3 and 2/3 colored ones (5,166 and 27,235 kg/ha, respectively). Higher green yields were mainly due to increased numbers of marketable fruits rather than increased fruit size. The longer the pods stayed on the plants, the more likely was sunscald to occur. Retail values (/ha) for the early fancy grade were $10,800 and $20,500 for the green and colored peppers, respectively (using $2 and $6/kg, respectively). These results suggest that the present higher retail value of the colored bell peppers off-sets the lower expected yields.
