The purpose of this study was to determine the growth response of tomato (Lycopersicon esculentum Mill.) and bell pepper (Capsicum annuum L.) transplants to corn gluten meal, an organic by-product of the corn wet milling process with allelopathic and herbicidal properties. Replicated greenhouse studies were conducted to evaluate the effect of corn gluten meal applied at rates of 0, 2, 4, 6, 8, and 10 grams/plant to 5, 6, or 7 week old transplants. Shoot dry weight, root dry weight, and total leaf area decreased as the rate of corn gluten meal increased in the five week old tomato transplants. When the transplants were six or seven weeks old differences in shoot and root dry weights were similar for all treatment rates. Significant differences in shoot dry weight and leaf area of the 5, 6, or 7 week old bell pepper transplants were not observed. However, root dry weight of 5 week old bell pepper transplants decreased with increasing rates of corn gluten meal.
