Abstract
Abstract Field studies were conducted on an Orangeburg sandy loam soil (Typic Paleudults) in central Alabama to determine the effects of tillage methods (complete, strip, and no-tillage), nitrogen rates (100 and 200 kg/ha), and rye ( Secale cereale ) cover crop on growth and yield of tomatoes ( Lycopersicon esculentum Mill.). Marketable tomato yields tended to decrease as amount of tillage decreased. The 3-year average yields for complete-tillage, strip-tillage, and no-tillage treatments were 29.9, 27.0, and 26.0 MT/ha, respectively. There was no consistent effect from N-rate on marketable yields. Average yields from the lower N-rate were greater than the higher N-rate in the two driest years and were similar or higher from the higher N-rate in the year of more average rainfall. Marketable yields tended to be greater on no-rye plots than on rye plots, with yields averaging 2.2 MT/ha higher for no-rye plots.
