Abstract: The investigation entitled “Effect of foliar feeding of plant growth regulators and nutrients on morphological and yield attributing characteristics of Guava (Psidium guajava L.) cv. Gwalior-27” was carried out in the Fruit orchard, Department of Horticulture, R.V.S.K.V.V, CoA, Gwalior district of Madhya Pradesh during mrig-bahar of 2021-22 and 2022-2023. The field experiment was laid under FRBD (Factorial randomized block design) which comprised of 20 treatments combinations of various PGR’s and nutrients and were replicated thrice. The results implied that among all the morphological characteristics i.e., polar diameter (8.13 cm), equatorial diameter (8.11 cm), average fruit weight (212.08 g) and fruit volume (209.47 cm³) and among all the yield attributing characteristics i.e., number of fruits per plant (225.50), yield / plant (45.40 kg) and yield / hectare (126.10 q), the highest value were found in the treatment combination P₄M₁ (Gibberellic acid 100 ppm + Borax 0.4%) followed by P₄M₂ (Gibberellic acid 100 ppm + ZnSO₄ 0.5%) as compared to P₀M₀ (control).
