Effect of Micronutrients and Sea Weed Sap on Fruit Set, Yield and Quality of Mango (Mangifera indica L.) cv. Dashehari

The present investigation was carried out at GBPUA&T, Pantnagar, U.S. Nagar, Uttarakhand during the year 2015 to study the effect of micronutrients and sea weed sap in mango cv. Dashehari. The investigation has shown that the application of RDF + foliar spray of ZnSO4 @ 0.4 % + CuSO4 @ 0.2 % + Boric acid @ 0.2% (2 sprays at just before flowering and marble stage) was found to be most effective for increasing number of fruits per panicle at pea and marble stage (9.67 and 4.58, respectively), yield plant-1 (271.51 kg), yield ha-1 (27151 kg), per cent increase in yield (56.40 %), TSS (18.51 oB), total sugar (12.88 %), ascorbic acid content (43.62 mg 100 g-1 pulp) with reduced acidity (0.149 %). The higher fruit weight (221.98 g), fruit length (10.87 cm) and fruit width (6.54 cm) were observed with the application of RDF + 10 % sea weed sap (2 sprays at panicle emergence and marble stage) + ZnSO4 @ 200 g + CuSO4 @ 100 g + Boric acid @ 100 g (soil application). Thus, it is concluded that the basal application of recommended dose of fertilizer (RDF) with foliar spray of micronutrients may be helpful in upliftment of yield and quality of mango cv. Dashehari.
