The research work was done on six pruning time’s i.e. 15th May, 15th June, 15th July, 15th August, 15th Sept and Control and seven different genotypes such as Sardar, RHR-Guv-58, RHR-Guv-60, RHR-Guv-14, RHR-Guv-16, RHR-Guv-3, and RHR-Guv-6. The experiment was laid out in a factorial randomized block design with forty-two treatments replicated two times. The Minimum time required for initiation of new shoots was observed in 15th May pruning time and in Sardar and also in their interactions. Similarly, a maximum number of sprouted shoots per tree was noted in pruning time Control and Sardar genotype.
15th May time of pruning, genotype Sardar and interaction between them were found significantly better for total yield per plant, but marketable yield free from fruit fly infestation were significantly recorded higher in 15th July time of pruning and its interaction with Sardar, followed by RHR-Guv-14. Pruning time of 15th September was found to be better in the escape from fruit fly infestation but fruiting was minimum in September pruning as compared to other pruning time, followed by 15th August pruning time.

Key words: Psidium guajava, Pruning time, Shoot sprouting, Fruit fly incidence, Fruit yield
