Abstract: Foliar fertilization is way of supplying supplementary doses of minor and major nutrients, plant hormones, and other beneficial substances to plants. A pot experiment was conducted at the Crop Farm, Eastern University Sri Lanka to identify the effects of folair application of Hydrangea macrophylla L. leaf extract (HmLE) on the growth and yield of mungbean (Vigna radiata L.) var. ‘MI 5’. The experiment was arranged in Completely Randomized Design with 5 treatments and 4 replications. Once a week HmLE was applied at four different concentrations (T2: 10%, T3: 20%, T4: 50% and T5: 100%) and distilled water was applied as control (T1). The crop performance was recorded from two weeks after planting (WAP) to eight WAP. Analysis of variance was performed to compare effectiveness of treatments. Foliar application of HmLE had significant (P<0.05%) effects on measured parameters of Vigna radiata over the control. Application of 20 % HmLE increased plant height (32.81%), root length (21.78%), leaf chlorophyll content (48.27%), leaf area (113%), Number of flowers per plant (50%), number of pods per plant (85.71%), Dry weight of shoot (132.93%), Number of effective nodules (224.32%) and Inter node length (72.59%) over the control. This could be due to availability of micro, macro and gibberellins in the HmLE. From the findings it could be concluded that, application of 20% HmLE could be recommended for mungbean (Vigna radiata L.) cultivation as an environment friendly practice to improve growth and yield.
