Abstract: The present experiment was carried out at Guava orchard of ICAR, KVK- Vijayapura-1 during Mrig Bahar to find out the effect of Gibberellic acid (GA₃) and Naphthalene acetic acid (NAA). Five treatments were employed viz., T₁- control, T₂-100 ppm GA₃, T₃- 200 ppm GA₃, T₄- 150 ppm NAA, T₅- 250 ppm NAA and each treatment were replicated for three times. All treatments significantly performed better as compared to control. According to the results obtained, the maximum plant height was recorded in the plants treated with 150 ppm NAA (T₄ treatment), whereas, minimum plant height was noticed in control treatment of no growth regulator treatment (T₁). In the same way, maximum number of flowers/plant (63.22), maximum fruits per plant 48.20), higher fruit weight (178. 41 g), higher fruit diameter (7.18 cm) and maximum fruit yield per plant (24.53 kg) was recorded in T₄ treatment of 150 ppm NAA foliar feeding and minimum values for all these parameters were recorded in control treatment (T₁). Therefore, foliar feeding of NAA (150 ppm) followed by GA 3 (200 ppm) are recommended better growth, flowering, fruiting and final yield of guava and which is may be used for commercial cultivation of guava with good economic returns.
