A 10-year study of 4 vegetation management regimes in an apple ( Malus domestica Borkh.) orchard showed that a mowed sod ground cover resulted in less efficient trees than those with cultivation, residual or nonresidual herbicides. Considerable differences were found among treatments in the kind and population density of orchard weeds. Of the 6 rootstocks tested, seedlings produced the largest but least efficient trees. Trees on Mailing (M) 4, M 1 and M 7 rootstocks gave the greatest yield efficiency during the 10-year period. No interactions were found between rootstock and orchard floor management practices.
