Growth and production of sweet corn (Zea mays) using monoculture and intercropping systems on gambier plants (U. gambir). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. 8–33). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Gambir (Uncaria gambir Roxb.) is a plant that grows in tropical regions and is used as a remedy for chickenpox. The relatively wide planting space of gambir leaves unused areas that have not been optimally utilized. This study aimed to determine the growth and yield of sweet corn (Zea mays) grown in monoculture and as an intercrop with gambir. The research was conducted from November 2007 to January 2008 at the Experimental Farm of the Faculty of Agriculture, Sriwijaya University, Indralaya, Ogan Ilir Regency. The method used in this study was a Randomized Block Design (RBD) with two treatments, namely J0 (sweet corn monoculture) and J1 (polyculture with gambir), each replicated four times, resulting in eight experimental units with 40 plants per unit. The analysis of variance showed that the planting pattern treatments (monoculture and intercrop) had a significant effect on crop yield. The study explained that the growth of sweet corn in treatment J0 (monoculture) was better than in treatment J1 (intercrop). The fresh and dry weights of sweet corn biomass in the monoculture pattern (J0) were higher than those in the intercrop pattern (J1). Thus, the growth and yield of sweet corn were better when planted in monoculture compared to polyculture as an intercrop with gambir.]]>
