Abstract:
An investigation was carried-out at fruit research station, Department of Horticulture, JNKVV, Jabalpur during the season of 2014-15 on 5 years old orchard of mango, to evaluate the positive effect of foliar sprays of PGR’ and nutrients on fruiting, yield and quality characteristics in Amrapali mango. The experiment was laid out in Randomized Block design in three replications and treatments replicated thrice by using single tree as a units. Each treatment was carried out one tree for each replication. Spraying of combination of nutrients viz., KNO3 (2%), urea (2%), ZnSO4 (0.8%) and FeSO4 (0.4%) and growth regulators viz., NAA (50 & 25 ppm) and GA3 (30 & 20 ppm) was compared with control (no spray). The experimental results indicate that the foliar spray of GA3 30 ppm + KNO3 2% showed better performance in Higher number of fruits at initial stage (63.81), more fruit retention percentage at harvest stage (1.94%), fruit yield (14.70 kg/ tree), fruit weight (182.29 g), fruit length(9.91 cm), fruit width (6.90 cm), fruit volume (172.01 ml) and peel weight(31.36 g). Under the treatment T6 (NAA 50 ppm + KNO3 2%) was recorded significantly maximum pulp weight (105.73g) which were at par with T2. However, it was noted minimum in control (T17) and reverse trend was noted in case of stone weight. Significantly minimum stone weight (21.41g) was recorded in treatment T6 (NAA 50 ppm + KNO3 2%).Biochemical parameter like TSS, Acidity, Ascobic acid, Reducing sugar, Total sugar and Non-reducing sugar were observed. However the chemical composition of fruit viz., maximum TSS (22.05 0Brix), TSS: acid ratio (184.22), Ascorbic acid content (54.33 mg/100g), reducing sugars (6.90%), total sugars (18.09%) and minimum acidity content (0.12%) were recorded with the application of T14 (GA3 30 ppm + KNO3 2%) which was at par with T10(GA3 20 ppm+ KNO3 2%) during the year of experimentation.
