What do I need to know about organic sweet pepper production and where can I get the information?
E.N.KansasAnswer: The following comments touch on the main points associated with pepper production. A list of Resources follows.Peppers are a warm-season crop. They are in the nightshade family, which includes tomatoes, eggplants, and potatoes. Do not plant peppers after other nightshades to avoid diseases.There are two main categories of peppers: sweet bell peppers and hot peppers. However, there are dozens of pod types and varieties of peppers. Many varieties are available to choose from. Colored, pungent, and uniquely-shaped varieties are often grown as “specialty” crops. Peppers are raised for both fresh and processing markets.Sweet bell peppers are commonly established from transplants and plugs on market farms and in commercial vegetable production. Hot peppers are often direct-seeded on large acreage farms.When direct seeding is used, seed priming and gel seeding are practices that can improve stand establishment. When peppers are raised for mechanical harvest, plants established by the direct-seed method are better suited to mechanical harvest (due to morphology and plant architecture) than plants established by transplanting.Depending on cultivation equipment and planting materials, row spacing can be 18 to 36 inches. Inrow spacing is 12 to 16 inches. Twin rows on beds with or without plastic mulch is a common method of production.Peppers are commonly grown on bare soil and managed by clean cultivation. Other systems include plasticulture (plastic mulch combined with drip irrigation) and organic mulches.Plastic mulches increase pepper yields in moderate climates, because the plastic mulch traps solar energy and results in higher soil temperatures, which enhances early vegetative growth and fruiting. Plastic mulches may reduce yields in the South, because the soil can reach extreme temperatures and thus affect flowering, pod set, and fruiting.Insect pests of peppers include flea beetles, Colorado potato beetles, aphids, leafhoppers, pepper weevils, tomato hornworms, and tomato fruitworms. Pepper diseases include Phytophthora root rot, anthracnose, bacterial leaf spot, tobacco mosaic virus, Alternaria fruit rot, southern blight, and sunscald.Certain insect or disease pests may become troublesome in specific regions of the U.S.; e.g., bacterial leaf spot in the Northeast, pepper weevil in the Southwest, southern blight in the Southeast. Green bell peppers are picked when they are fully firm and well-shaped. Colored bell peppers have extra flavor, nutrition, and aesthetic appeal, and therefore fetch a higher market price. Colored peppers are obtained by leaving the fruits on the bush until they reach mature color (e.g., red, yellow, orange). Greenhouse-grown peppers, including Dutch bell peppers imported from The Netherlands, make up a portion of the colored pepper market.Hot peppers are raised for processing and fresh markets.Significant hand labor is involved in picking and packing fresh market pepper fruits; mechanical harvesting is done on spice peppers intended for the processing market.Many organic growers consider peppers to be a fairly easy crop to grow. Specialty peppers are a steady seller at farmers’ markets and roadside stands. Read the ATTRA publication Organic Tomato Production for organic production methods for tomatoes and peppers; also see Overview of Organic Crop Production and Resource Guide to Organic and Sustainable Vegetable Production.The Cooperative Extension Service can provide Extension fact sheets and bulletins with variety recommendations and standard cultural practices.ResourcesATTRA Publications: Organic Tomato Production Organic Crop Production Overview Resource Guide to Organic and Sustainable Vegetable ProductionAnon. 1994.

DeWitt is the editor of Chile Pepper magazine and has also compiled a bibliography on peppers. This book provides a nice introduction to pepper pod types and varieties, the history of pepper growing, and raising peppers in the home garden and for commercial production. Seed sources and supplies are listed in the back. This book belongs on every pepper grower’s bookshelf.
The Whole Chile Pepper Book by Dave DeWitt and N. Gerlach. 1990. Little Brown and Co., Boston, MA. 373 p.
Another book by DeWitt that should be especially useful to the hot pepper grower.
Peppers: The Domesticated Capsicums by Jean Andrews. 1984. University of Texas Press, Austin, TX. 170 p.
Andrews’ book is a classic treatise on peppers. It contains chapters on agronomy, biology, history, and economic uses. It also contains an exhaustive description of pepper types (Poblano, Jalapeno, Hungarian Wax, Bell, etc.). The information in this book could be especially helpful in developing tip sheets and marketing brochures for sale of peppers at farmers’ markets.
