The experimental results revealed that, In respect of growth and yield parameters viz., height of tree, plant spread, tree canopy, per cent fruit set, number of flower per branch, fruit drop, fruit diameter, fruit volume, fruit weight, number of fruits per plant and yield per plant significantly influenced by different chemical treatments. Among the different treatments, T₆ (Kaolin 8%) increased the tree height (0.67 m) and tree canopy (13.72 m³) significantly, whereas the effect of different chemicals on increase in plant spread shows non-significant effect. While, T₄ (KNO₃ 2%) shows positively significant effect on number of flower per branch (2726.15), per cent fruit drop (61.50%).

The yield parameters viz., fruit weight (319.67 g), fruit diameter (9.36 cm), fruit volume (295.15 ml) and yield per tree (102.98 kg) were significantly maximum in T₄ (KNO₃ 2%). however, significantly maximum number of fruits per plant (343.04) were recorded in T₆ (Kaolin 8%).

On the basis of overall performance for growth character T₆ (Kaolin 8%), and for yield parameters T₄ (KNO₃ 2%) was found to be best management strategy for getting higher quality production and productivity. It can be beneficial for effective and economic management practices for sweet orange.
