Effect of different concentration of nutrient and PGRs on quality of mango (Mangifera indica L.) cv. Amrapalli under valley conditions of Garhwal hill

The experiment was carried out to study the “Effect of Different Concentration of Nutrient and PGRs on Quality of Mango cv. Amrapalli under Valley Conditions of Garhwal Hill” at the Horticultural Research Centre and Department of Horticulture, Chauras campus, H.N.B. Garhwal University, Srinagar Garhwal (Uttarakhand), India. The experiment was laid out in Randomized Block Design with 14 treatments and 3 replications. The results of the analysis of variance revealed that the mean sum of squares due to treatment were significant at 5% level for almost all parameters except pulp stone ratio which was found non-significant. The results revealed that maximum peel weight (15.25 gm), pulp weight (161.20 gm), pulp and peel ratio (10.75), stone weight (23.67 gm), pulp and stone ratio (4.48) were significantly recorded under the treatment NAA @ 50 ppm, whereas, in quality parameters, viz., total soluble solid (19.73ºBrix), ascorbic acid (41.43 mg/100 gm pulp), vitamin A (1037.67 IU/100 gm), total sugar (13.61), non reducing sugar (8.98%), reducing sugar (4.40%) were also found significantly in treatment KNO₃ @ 0.4%. Hence, NAA @ 50 ppm and KNO₃ @ 0.4% could be recommended to enhance the production of good quality of Mango cv. Amrapalli, under valley conditions of Garhwal hill.
