    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-05) Pankaj Kumar
    The present investigation was carried out at Horticulture Research Centre, Pattharchatta, G. B. Pant University of Agriculture and Technology, Pantnagar, district- Udham Singh Nagar, Uttarakhand during the year 2015-16. The experiment was laid out in RBD (Randomized Block Design) with 10 treatments and 3 replications. The results showed that the foliar application of macro and micronutrients exhibited improvement in fruit set, fruit yield, quality and nutrient status of soil and leaf. The investigation has shown that the application of RDF (1000 g N : 750 g P : 1000 g K) + NPK: 20:20:20 @ 1% (2 spray: first-15 days and second- 45 days after fruit set) + foliar spray of ZnSO4 @ 0.4% + Boric acid @ 0.2% + CuSO4 @ 0.2% (2 spray at just before flowering and marble stage) was found very effective for increasing the number of fruit set per panicle at marble stage (3.29), yield plant-1 890(228.24 kg), yield ha-1 (22.82 tonnes), per cent increase in yield (197.41 %), fruit weight (254.60 g), fruit length (10.86 cm) and fruit width (5.65 cm). The content of TSS (19.18 0B), total sugar (15.38 %), reducing sugar (3.94 %), non-reducing sugar (11.47 %), total carotenoids (12.08 mg 100 g-1 pulp) and ascorbic acid (48.47 mg 100 g-1 pulp) were also increased with this treatment. The results have shown that there was no consistency with respect to the effect of macro and micronutrients on soil and leaf nutrient status. Thus, it is concluded that the foliar application of NPK (20:20:20) @ 1 % + ZnSO4 @ 0.4 % + Boric acid @ 0.2 % + CuSO4 @ 0.2 % along with RDF (1000 g N : 750 g P : 1000 g K) may be adopted for improving fruit set, yield and quality of mango cv. Dashehari.
