Abstract

Close analyses of the present investigation revealed that the foliar application of nutrients were able to increase the yield of banana cv. ‘Grand Naine’. Present study was carried out at the field of Banana Research Station, Nanded (M.S.). The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments and three replications. Among these treatments maximum height of plant (183.6 cm) was recorded by treatment T11, i.e. spraying of potassium (0.5%), the significant maximum girth of stems (73.2 cm) was recorded in treatment T7 i.e. spray of, number of leaves per plant (14.17) was recorded with treatment T10. The treatment T10 was significantly influenced in maturity parameters viz. minimum days required from flowering to maturity (122.83 days), minimum days required from maturity to ripening (8.33 days) and minimum crop duration (368.83 days). The treatment T10, i.e. foliar application of Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%) was significantly superior in yield contributing attributes to other nutrient treatments. The highest number of fingers per hand (19.26), maximum length of finger (17.63 cm), maximum weight of finger (114.86 g), maximum circumference of finger (11.9 cm), maximum number of hands per bunch (9.61), highest number of fingers per bunch (186.09), maximum weight of bunch (21.64 kg) and maximum yield (96.19 Mt/ha) was recorded in treatment T10 i.e. Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%). Among the thirteen different treatments sprays with Zn (0.5 %) + Fe (0.2 %) + Cu (0.2 %) + B (0.1 %) was found to be more effective in increasing the yield and yield contributing characters.
