Abstract

Studies were conducted to evaluate conventional and reduced-tillage systems for winter annual cover crops used for early season weed suppression in green bean ( Phaseolus vulgaris L.) and tomato ( Lycopersicon esculentum Mill.) grown in central Iowa. The tillage systems and cover crops were: 1) conventional tillage annual rye, 2) no-till annual rye, 3) no-till hairy vetch, 4) no-till annual rye + hairy vetch mixture, and 5) conventional tillage in fallow plots. Experimental treatment plots were established as a randomized complete block design with four replications at the Horticulture Research Station near Ames. Early and total yield of green bean were affected by the tillage and cover crop systems. Differences were also observed in pod tenderness. Early tomato yield was influenced by the tillage and cover crop treatments but total yields were similar among all treatments. Soil organic matter and root dry weights were similar among all treatments for both crops.
