Pant University of Agriculture and Technology, Pantnagar (Udham Singh Nagar), Uttrakhand during the year 2012-13 and 2013-14. The experiment was conducted on 4 year old peach trees of cv. Florida Prince consisting of fourteen treatments in ‘Randomized Block Design’ with three replications. Maximum tree height, relative trunk girth increment, average tree spread, tree volume, chlorophyll (a, b and total), leaf area, number of flowers per shoot, initial fruit setting per cent, final fruit setting per cent, number of fruit per tree, fruit yield, fruit weight, fruit volume, fruit length, fruit breadth, weight of pulp, specific gravity, stone weight, organoleptic rating, T.S.S., ascorbic acid, reducing sugars and total sugars, leaf nitrogen, phosphorus, potash, boron, zinc and iron content and minimum fruit drop, titrable acidity, physiological loss was found with the application of FYM 30 kg + vermicompost 10 kg + poultry manures 2.5 kg + neem cake 3 kg tree-1 in both years. The maximum pulp stone ratio was obtained with the application of neem cake 7 kg tree-1. The application of Poultry manures 5 kg tree-1 gave the higher value of non-reducing sugar. Increased in TSS, reducing, non-reducing and total sugars from day of harvest for 3 days of storage then it denied under all the treatments while titrable acidity and ascorbic acid was continuously decreasing from the day of harvest during both the years. Maximum TSS, reducing sugars, total sugars, ascorbic acid and minimum acidity was found with the application of FYM 30 kg + vermicompost 10 kg + poultry manures 2.5 kg + neem cake 3 kg tree-1 for 4 days of storage during both the years. The application of FYM 30 kg + vermicompost 10 kg + poultry manures 2.5 kg + neem cake 3 kg tree-1 is useful for improving the growth, yield, quality and shelf life of peach cv. Florida Prince.ennullThesis
