Abstract

This study examined whether zone tillage was a viable alternative to conventional tillage for carrot [Daucus carota L. var. sativus (Hoffm.) Arcang.] and onion (Allium cepa L.) production on muck soils. Total and marketable yields under zone tillage were e qual to (carrot) or greater than (onion) yields under conventional tillage. Carrot yields did not differ between raised and flat bed treatments. Key words: Reduced tillage, conventional tillage, Daucus carota L. var. sativus (Hoffm.) Arcang.); Allium cepa L.
