Present study deals with the effect of grafting on fruit setting and bearing pattern of Pyrus pashia grafted with Pyrus communis var. Bartlett. The rootstock exert a pronounced effect on nutrient uptake, growth, longevity, productivity and fruit quality of the cultivars grafted on them. 5.0 and 7.5 cm girth size rootstocks of Pyrus pashia were grafted with the scion of Pyrus communis var bartlett having four buds. During first and second year of study no fruit setting was observed in either root stocks while maximum fruit setting was recorded to be 66.00 and 63.15% in 5.0 cm. and 7.5 cm girth size rootstock respectively. During third year, the fruit bearing was recorded to be 44 and 47% in 5.0 cm and 7.5 cm girth size rootstocks respectively.
