Studies on influences of pre-soaking treatments, application of growth promoting substances and method and season of grafting on seed germination, growth enhancement of Khirnee rootstock and graft success in sapota respectively were conducted during 1996 to 2000. The study revealed that pre-soaking of Khirnee seeds (Rootstock of Sapota) in cowdrug slurry for 24 hours resulted in higher (66.83%) seed germination. Khirnee seedlings sprayed with GA-200 ppm at 3rd and 6th month has enhanced the seedling growth. Inarching method of grafting had higher success of grafts during June-July season.
