39. The influence of timing and position of scion on graft take success of lemon

Abstract

The Propagation of lemon (Citrus lemon L.) trees is possible by seed, cuttings, layering, budding and grafting. Grafting require compatible rootstock and scion wood. Keeping in view the importance of vegetative propagation in lemon the present research was designed to find out the most suitable time and grafting side for the successful T-grafting of lemon. This study was conducted at Jabban Agriculture Extension Department Dargai Malakand during the year 2015. The experiment was carried out in Randomized Complete Block Design (RCBD) with two factors, replicated three times. There were five treatments in each replication. The lemon were grafted on sour orang rootstock with three different time interval (21^nd June, 29^th June, and 06^th July) and three grafting sides north, east and west. The results of study showed that all parameters were significantly affected by time interval and scion position. The mean values for graft direction shows early sprouting (28.1 days) was at east side, maximum graft length (9.8cm), number of branches graft^-1 (2.3) and number of leaves (12.6) at west side, maximum leaf area (16.9 cm²) at east side, while the mean values for the different grafting timing of the experiments shows early sprouting (29.1 days) at 29^th Jun, maximum graft length (9.9cm), maximum number of leaves (11.9) and maximum number of branches graft^-1 (2.0) at 6^th July, maximum leaf area (16.4 cm²) at 29^th Jun. On the basis of statistical analysis and result first week of July and east direction significantly affected most of the observed parameters, so therefore it is recommended that the 1^st  week of the month of July and east side is best for grafting in Lemon under the agro ecological conditions of Malakand valley Khyber Pakhtunkhwa.
