Abstract: 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 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 treatment 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) was found very effective for increasing yield plant-1 (228.24 kg).The results related to soil and leaf nutrient status are varied and showed that higher available nitrogen (212.47 kg ha-1) in soil was found with the application of T10 treatment whereas, the higher available phosphorus (75.79 kg ha-1) and potassium (223.46 kg ha-1) in soil were found with the application of T8: RDF + IIHR Mango Special @ 5 g/l (2 sprays at two months before flowering and marble stage).The micronutrient status of soil showed that the available boron (1.70 ppm) and iron (22.92 ppm) were found higher in soil with the application of T10 treatment However, higher zinc (0.91 ppm), copper (3.24 ppm) and manganese (26.09 ppm) content in soil were found with the application of T8 treatment. The significantly higher leaf nitrogen (1.96 %), phosphorus (0.99 %), potassium (0.87 %), iron (198.27 ppm), boron (19.87 ppm) and manganese (60.88 ppm) were found with the application of T8 treatment whereas, zinc (33.14 ppm) and copper (37.40 ppm) were found higher with the application of 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).
