Abstract

Abstract There were no significant yield differences among tillage systems of carrots ( Daucus carota L. cv. Danvers 126) planted into a rye mulch, soybean stubble, and conventionally tilled plots. Secondary root growth of carrot was greater in soybean than either rye or conventionally-tilled carrot plots. Irrigation decreased secondary root growth in conventional tilled and rye mulch plots, but not in the soybean stubble.
