Poor quality and fruit fly infested fruit in the rainy season and failure to manipulate production periods are common problems for guava production in India. So, the research work was carried out with a management practices point of view to overcome these problems. Growth characters were significantly influenced by different genotypes. The plant spread, number of sprouted shoots was recorded maximum in cv. Sardar. Marketable yield free from fruit fly infestation were significantly higher recorded in 15th July time of pruning and its interaction with cv. Sardar. As concerned with qualitative attributes the genotype Sardar was observed better in T.S.S. as compared to other genotypes. RHR-Guv-14 genotype was found to be maximum in ascorbic acid. Sugar: acid ratio was observed higher in RHR-Guv-60. Similarly maximum shelf life of fruit was recorded by the RHR-Guv-14. Very crispy pulp texture and fruit luster was observed in all genotypes except cv. Sardar. From the present investigation, it was found that 15th July pruning time was found to be better with respect to marketable yield. Pruning time of 15th September was found to be better in the escape from fruit fly infestation but fruiting was very less. The genotype RHR-Guv-14 may evaluate for the cultivation as hast bahar crop.
