The present investigation entitled “Effect of different Inorganic, Organic and Bio-fertilizers on plant growth of Sweet Orange (Citrus sinensis Osbeck)” were carried out at experimental field, Department of Horticulture, Allahabad School of Agriculture, Sam Higginbottom Institute of Agriculture, Technology and Sciences Allahabad (Uttar Pradesh) during the year (2015-2016). The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments and each replicated thrice. The treatment T6 (20 kg/plant Farm Yard Manure, 10 g/plant PSB, 10 g/plant Azosprillium, Nitrogen 337 g/plant, Phosphorus 112 g/plant and Potash 75g/ plant was found to be the most suitable in terms of maximum plant height (119.87 cm), maximum number of leaves (400.90), maximum number of branches (29.83), maximum stem diameter (2.40 cm), maximum spread of canopy (75.62 cm2), maximum Leaf area (32.46 cm2), maximum length of inter-nodes (8.60 cm) and minimum incidence of disease percentage (1.10 %) followed by treatment T12 (20 kg/plant Farm Yard Manure, 10 g/plant PSB, 10 g/plant Azosprillium, Nitrogen 225 g/plant, Phosphorus 75 g/plant and Potash 50 g/plant, whereas the minimum parameters were found associated with (T0) control. The nutrient status of soil like EC, Nitrogen, Phosphorous and Potassium were also higher with treatment T6 and the maximum pH was recorded with (T0) control. The results of the present study suggested that combination of Inorganic, Organic and Bio-fertilizers are responsible for increased growth of sweet orange.
