Utilization of gamal biomass (Gliricidia sepium) as organic mulch on corn (Zea mays L.) plants on dry land

This research aimed to determine the effect of giving gamal leaf mulch on nitrogen uptake of maize (Zea mays L). The purpose of this research is to provide information to farmers to develop and improve the yield of corn plants through the use of organic mulch leaves. This study used a randomized block design (RBD), which consisted of 3 treatments repeated 3 times so that 9 experimental units were obtained. Each treatment was: without mulch (control plot) (M0), plastic mulch (M1), gamal biomass mulch (M2). The results obtained in this study indicate that the treatment of gamal leaf organic mulch (M2) showed the best results based on the observation of weight production of 100 plants with production reaching 8.87 kg, on observing the weight of 100 seeds which weighed 26.22 g for 100 seeds, and weight seeds/production plots reach 177.33 kg/plot and reach 4.43 tons/ha if converted to ha.
