Effect of soil and foliar application of macro and micronutrients on flowering, fruit set and yield of mango cv. Dashehari

The experiment 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 earlier (February10-February 19) panicle emergence, maximum duration of flowering (27.66 days), number of fruit set per panicle at marble stage was found significantly higher (3.69), higher yield plant⁻¹ (228.24 kg) and maximum shelf life (12.33 days) were found with the application of T₁₀: RDF + 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). The maximum flowering intensity percentage was found maximum (48.48%) in T₇ [RDF + ZnSO4 @ 100 g + CuSO4 @ 50 g + Boric acid @ 50 g (soil application) + Foliar spray of ZnSO4 @ 0.2% + CuSO4 @ 0.1% + Boric acid @ 0.1% (2 sprays at just before flowering and marble stage], the minimum flowering intensity (32.66%) percentage was obtained in T₁ [Control (RDF)].
