Observation of the effects of depth of planting on growth, flowering and productivity of apple trees cv. 'Elstar' on M.9

Abstract

The results obtain during five years of study shown that depth of planting significantly affected growth, flowering and cropping efficiency. Trees planted of the place of budding 7 cm under the ground (the deeplyest) had significantly bigger trunk cross section area, volume of crown and the lowest cropping efficiency than planting the place of budding 15 cm upper the ground (the shallowest). The trees planted the deeplyest gave about twice lower flowers per tree and 1ha of orchard than others planted upper.
