The experiment was carried out at the Germplasm Centre, Department of Horticulture, Bangladesh Agricultural University (BAU), Mymensingh during the fruiting season of 2005-06. Investigations related to bio-chemical analysis were carried out in the Department of Biochemistry of BAU, Mymensingh. The eight years old Amrapali plants with a plant spacing of 5x5m were used in the study. The factorial experiment was laid out in a Randomized Complete Block Design with three replications. Fertilizer at the rate of cowdung 25 kg, urea750g, TSP400 g, MoP 250 g, gypsum 250 g and zinc sulphate 15 g per plant proposed in the Manual on mango cultivation in Bangladesh by Hossain, (1989) were used as fertilizer dose in the study. Four fertilizer doses i.e. T1 : 50% of the fertilizer dose (cowdung 12.5 kg, urea 375 g, TSP200g, MoP125 g, gypsum 125 g and zinc sulphate 7.5 g per plant), T2 : 100% of the fertilizer dose (cowdung 25 kg, urea 750 g, TSP400 g, MoP 250 g, gypsum 250 g and zinc sulphate 15 g per plant), T3 : 150% of the fertilizer dose (cowdung 37.5 kg, urea 1125 g, TSP 600 g, MoP 375 g, gypsum 375 g and zinc sulphate 22.5 g per plant), and T4 : control (no fertilizer) along with three splits of application i.e. A1 : One installment (whole fertilizer applied at a time on 15 September), A2 : Two installments (15 September and 15 March) and A3 : Three installments (15 September, 15 March and 15 May) were included as treatments. Basin type very light furrows were prepared around and 1.0 meter away from the base of each plant. Fertilizers were applied in the furrows and then thoroughly mixed up with the soil. In one installment (A1), the whole fertilizer was applied at a time on 15 September. In case of two installments (A2), the total amount of cowdung, TSP, gypsum and zinc sulphate and ½ of urea and ½ of MoP was applied on 15 September and the rest amount of urea and MoP applied on 15 March. In the case of three installments (A3), the total amount of cowdung, TSP, gypsum and zinc sulphate and ½ of urea and ½ of MoP was applied on 15 September, then ½ of the remaining amount of urea and MoP was applied as second installment on 15 March and the rest urea and MoP were applied as 3rd and final installment on 15 May. Very light irrigation was given at each time of fertilizer application. Very light irrigation was also provided to control (no fertilizer) plants in each time of fertilizer application. The parameters recorded were date of harvest, number of fruits per plant, fruit weight, length, breath and thickness, yield, edible portion, stone pulp ratio, peel pulp ratio, shelf-life, TSS, titratable acidity, vitamin C, dry matter, reducing sugar, non reducing sugar and total sugar content. After harvest, 10 randomly selected fruits were allowed to ripen at room temperature and fruit quality was determined using 10 fruits per tree. Total Soluble Solid (TSS) of 10 fully ripened fruits for each treatment was estimated by a hand refractometer and the average was worked out. The titratable acidity, vitamin C content, reducing sugar content and total sugar content of mango pulp were determined following the methods of Ranganna (1979) Plummer (1971), Miller, (1972) and Jayaraman (1981) respectively. The data were analyzed statistically by F-test and the treatment means were separated by Least Significant Difference (LSD) test at 5 % level of significance.
