Abstract
Field studies were conducted on Plinthic and Typic Paleudult soils in central Alabama to determine the response of tomatoes (Lycopersicon esculentum Mill), to furrow, sprinkle, and trickle irrigation with and without in-row chiseling. Irrigation by all methods and in-row chiseling increased plant heights which ranged from 70 to 120 cm at first harvest. Marketable tomato yields were influenced more by irrigation (37% increase) than by chiseling (8% increase). Yields averaged 36.7 metric tons/ha with no irrigation and 50.1 metric tons/ha with irrigation. No difference was found between irrigation methods. Amounts of irrigation water applied per season averaged 34.5 cm for furrow, 37.4 cm for sprinkle, and 16.0 cm for trickle. In-row chiseling increased yields an average of 3.7 metric tons/ha, but was significant in only 1 of 3 years.
