This study was conducted from February 2019 to March 2019 at Crop Science Experimental Area, Crop Science Department under the College of Agriculture Systems and Technology, Pampanga State Agricultural University, PAC Magalang, Pampanga. The experiment aimed to determine the influence of legume-based fermented plant juices (FPJ) on the growth and yield of upland kangkong. The experimental design used was Randomized Complete Block Design (RCBD) with three replications. The treatments were as follows: T1 - Control (Water), T2 - Fermented ipil-ipil, T3 - Fermented Tamarind, T4 - Fermented Pigeon pea and T5 - Farmers practice. The result revealed that there was significant effect of fermented plant juice on the plant height, stem diameter and computed yield per hectare. Based on the findings there were significant effect of farmers practice on the number of leaves and computed yield per hectare comparable with T3 - Fermented Tamarind leaves in computed yield per hectare.
