Seedless Watermelon Production: Extension's Role in Supporting a New Crop Enterprise

Abstract

In response to a national increase in the consumption of triploid (seedless) watermelons, seedless watermelon production in Delaware has increased to 43% of the total watermelon acreage. Cultural practices for triploid watermelon production are similar to seeded (diploid) types. However, poor seed germination, high seed costs, erratic performance, and inadequate varieties limited their adoption until the early 1990s in Delaware. Univ. of Delaware Cooperative Extension has worked with Delaware growers to develop a “recipe” for successful triploid production. Extension programs, such as on-farm demonstrations, research trials, educational seminars, and one-on-one consultations, have enabled producers to provide high-quality fruit and yields. Intensive management and marketing are the keys tosuccess as Delaware producers have become leaders of triploid production in the Northeast region. As demand for triploid watermelon continues to increase, extension will remain a vital part of the $4.5 million industry. Growers continually deal with marketing issues in a supply and demand-driven market. As more seedless are on the market and profits lessen, growers will have to be diligent in their marketing and management practices.
