Wedge grafting is a method of vegetative propagation which is standardized in guava propagation gave maximum number of success than other standard methods of propagation in guava. Present study revealed that wedge method of grafting was tried in guava (Psidium guajava) cultivars Allahabad Safeda Lucknow 49 and Lalit under greenhouse (GH) as well as in open field conditions with and without polycap. The grafting operation performed in greenhouse with polycap gave significantly higher success of grafts compared with other conditions of wedge grafting in all taken cultivars. However, maximum success of grafts was obtained in greenhouse (81.71%) and minimum in open field conditions (when grafting was carried out during September to December in all three cultivars. Grafting under greenhouse significantly reduced the time taken (12–13 days) for sprouting than those grafted in open field conditions. The temperature range of 24 to 26°C and 70 to 80 per cent RH were found most conductive for achieving maximum success.
