Effects of Plant Spacing with Companion Plants on Growth and Fruit Quality of Cherry Tomatoes

Urban Farm DB summary

This study investigated the effects of French marigold, zinnia, spearmint, and basil as companion plants at 10, 20, and 40 cm spacing on cherry tomato growth and fruit quality. Statistical differences were found in stem thickness and total number of fruits per plant, but not in plant height, total fresh weight of fruits, sugar content, fruit hardness, or vitamin C. Stem thickness decreased when spearmint and basil were planted at 20 cm or 40 cm compared to the control, and only zinnia at 40 cm increased the total number of fruits per plant.
