Abstract

The demand for corn (Zea mays L.) is steadily increasing due to its use as food, animal feed, and industrial raw material. This situation highlights the need for sustainable corn cultivation, particularly on Java Island, where arable land is shrinking. Intensification is considered a key strategy to enhance corn productivity without expanding agricultural land. This study aims to evaluate the interaction effects of SP-36 fertilizer and Galuh Agritama (GA) organic fertilizer dosages on the growth and yield of BISI 2 variety corn. The hypothesis tested is that there is a significant interaction between SP-36 and GA fertilizer dosages on the growth and yield of BISI 2 corn. The main findings are: (1) Significant interactions were observed for plant height (at 20, 35, and 50 days after planting), leaf number, stem diameter, dry kernel weight per plant, and the weight of 1000 dry kernels at 105 days after planting. (2) No significant interaction or main effects were found for the number of ears per plant at harvest. (3) The highest dry kernel weight per plant (96.74 g/plant or 9.674 tons/ha) was obtained with 150 kg/ha SP-36 and 6 tons/ha GA organic fertilizer
