This study conducted at the net house of Faculty of Sustainable Agriculture, University Malaysia Sabah, Sandakan. The objective of this study was to compare the effect of incorporated of organic and inorganic fertilizers on growth, yield and eating quality of the local yellow glutinous maize (Zea mays ceratina Kulesh). Biochar and chicken manure, Urea, Triple Single Phosphate (TSP), and Muriate of Potash (MOP)) and BRIS soil were used in this experiment. Four treatments were used namely treatment 1 (control, 120:60:60 NPK), 2 (120:60:30 NPK + organic fertilizers), 3(120:60:90 + organic fertilizers) and 4 (120:60:120 NPK + organic fertilizers). Each treatment applied different rates of potassium but same rate of others organic and inorganic fertilizers except treatment without organic fertilizers. The experimental design was Completely Randomized Design (CRD) with five replications. Data on plant height and numbers of leaf were recorded every one week. Parameters for yield components such as length of the cob, weight of the cob with and without husks, circumference of the cob, number of kernels, 100 grains fresh weight, 100 grains dry weight and sweetness of the corn were taken after harvesting. Nitrogen, hydrogen and carbon analysis also carried out by used of CHN machine. After that, results were analyzed using SAS and the treatment means were compared by Least Significance Difference (LSD) test at s % significant level. In this study, treatment 3 which was the treatment with adequate organic and inorganic had the positive effects on the plant height, circumference of the cob, number of grains, fresh weight of 100 grains, dry weight of 100 grains and sweetness of the maize although this treatment did not showed good effects to others parameters. Therefore, treatment 3 can be considered as the better treatment to improve growth, yield and eating quality to the maize.
