dc.description.abstractABSTRACT The present investigation entitled “Canopy management of rejuvenated apple trees through pruning and prohexadione-Ca treatments” was carried out at Regional Horticultural Research and Training Station, Mashobra, Shimla during the years 2015 and 2016. Pruning treatment with no heading back-only thinning out suppressed the vegetative growth and markedly improved the fruit set, yield and yield efficiency. It also improved red colouration and firmness of the fruits at harvest. Heading back (25% removal of one year old growth) increased vegetative growth and improved fruit quality in terms of size and total soluble solids. Two foliar applications of prohexadione-Ca at a concentration of 150 ppm significantly restricted the vegetative growth. Further, it was found to be effective in improving fruit set, yield efficiency, fruit colour and firmness. Return bloom on the basis of blossom density was improved by combining no heading back-only thinning out pruning cuts with two foliar applications of prohexadione-Ca at a concentration of 150 ppm. In order to regulate vegetative growth and fruiting in rejuvenated apple trees, the combination of no heading back-only thinning pruning cuts and two foliar applications of prohexadione-Ca at a concentration of 125 ppm and 150 ppm can be recommended for sustainable apple production.en_US
