Abstract:
A field experiment was conducted to know the influence of weather parameters on growth, yield and crop water balance in Mallika mango hybrid at “C” and “I” block, UAS, GKVK, Bengaluru during 2020-21. The plantations of Mallika hybrid of different ages (20 and 28 years), with and without plant protection chemicals were selected and data was analysed using FRBD with five replications. Among the different age of trees, mango trees of 28 years has shown higher tree height, volume and girth (5.91 m, 324.7 m³ and 1.33 m, respectively) compared to 20 years of age trees. Maximum number of flowers was noted in 20 years of age trees (1091.7), which were significantly higher than 28 years of age (1078.0) and spray treatment had shown significantly higher number of flowers (1100.7) compared to control (1069.1). Mango trees with 20 years of age had shown significantly higher volume of the fruit and mango yield (401.2 and 60.30 kg/tree) compared to 28 years old plantation (344.4 and 40.90 kg/ tree). But among the spray treatments, with spray treatment recorded significantly higher volume of the fruit and yield (387.1 and 58.02 kg/tree) compared to control (358.5 and 43.19 kg/ tree).
