An experiment was conducted during the year 2012-13and 2013–14 to examine the effect of different doses of organic manure on flowering, fruiting and yield of peach (cv. Florida Prince). The experiment was consisted of 14 treatments each replicated three times in a randomized block design. All the treatments had significant response on flowering, fruiting and yield. The results obtained from the investigation showed that the maximum number of flowers per shoot (12.80 and 12.96), maximum initial fruit setting per cent (87.50 and 87.70%), minimum fruit drop (38.29 and 38.01%), highest final fruit setting per cent (38.12 and 38.24%), maximum number of fruits per tree (322.43 and 334.81) and fruit yield (17.52 and 18.94 kg/tree were recorded with the application of FYM 30 kg+vermicompost 10 kg+poultry manure 2.5 kg+neem cake 3 kg/tree, while minimum number of flowers per shoot (6.86 and 7.03), minimum initial fruit setting per cent (75.43 and 75.84%), maximum fruit drop (83.62 and 83.06%), minimum final fruit setting per cent (31.91 and 32.07), minimum number of fruits per plant (234.52 and 248.52) and minimum fruit yield (13.51 and 15.85 kg/tree were recorded with the application of N: P: K, 200: 150: 200 g/trre during both the years, respectively. Organic manure alone or in combination was helpful in improving the flowering, fruiting and yield of peach cv. Florida Prince.
