Abstract:
The present investigation entitled “Effect of Different Concentration of Nutrient and PGRs on Physico-chemical Quality and Yield of Mango cv. Amrapalli under Valley Conditions of Garhwal Hill” was carried out at the Horticultural Research Centre and Department of Horticulture, Chauras campus, H.N.B. Garhwal University, Srinagar Garhwal (Uttarakhand), India during the year 2017. The experiment was laid out in Randomized Block Design with 14 treatments and 3 replications. The results revealed that maximum fruit weight (212.81 gm), fruit length (10.66 cm), fruit diameter (7.26 cm), fruit volume (209.54 cc), specific gravity (1.04 gm/ml), pulp weight (161.20 gm), stone length (4.71 cm), stone diameter (2.15 cm), yield/plant (10.50 kg/tree) and number of fruits/kg (4.26) were significantly recorded under the treatment NAA @ 50 ppm, whereas, in quality parameters, viz., TSS (19.73ºBrix), titratable acidity (0.15%), TSS/acidity ratio (131.53) 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.
