Abstract

To find out the ideal factors which affect the graft success of walnut, an experiment was carried out at experimental farm of Central Institute of Temperate Horticulture during 2008-2009 with three environmental conditions (open field, polytrench and polyhouse), two grafting methods (wedge grafting and tongue grafting) and four grafting times (15 February, 1 March, 15 March and 1 April ). Polyhouse recorded highest percentage of sprouting (65.51 %), graft success (54.46 %) and plant growth (168.75 cm). Wedge grafting was found superior to tongue grafting in respect of sprouting percent (62.22 %), graft success (52.45 %) and plant height (151.5 cm). Amongst the grafting times 15 March recorded the highest graft success (58.00 %) and plant growth (163.78 cm). The highest sprouting (80.00 %) and graft success (64.62 %) was found under polyhouse with wedge grafting performed on 15 of March under Kashmir conditions can be adopted for mass multiplication.
