The apple trees of ‘Jonagold’ on rootstocks P 22, M.9, P 60, M.26 were planted in the orchard as grafted rootstocks (spring 1994) and as maiden trees (spring 1995). The clone of rootstock had the greatest effect on the growth and yield of estimated trees. Irrespective of propagation methods and irrigation, the yield obtained from ‘Jonagold’ apple trees on P 22 was lower than from those on other rootstocks. Planting grafted rootstocks directly in the orchard seemed to be a good method for M.9 rootstock. The highest yields were obtained from trees grafted on M.9 rootstock with the use of irrigation, which also positively affected the yield of trees grafted on P 60 rootstock.
