There is no available information in determining soybean varieties that shows tolerant when intercropped with maize. The objective of this study was to determine soybean varieties suitable for intercropping, based on changes in plant growth and yield when intercropped. The field experiment was conducted from October 2019 to February 2020 based on RCBD with 2 factors. The first factor was soybean with 16 national varieties. The second was cropping systems i.e., monoculture and intercropping. Morphology and yield data were observed and subsequently analysed based on performance difference (D) of each parameter between intercropping and monoculture. Tolerance level to cropping systems with maize was grouped based on the yield-based and selection index calculations. The results showed that different cropping systems affected morphological and yield parameters on 16 tested soybean varieties. Seven varieties i.e., Derap 1, Devon 1, Devon 2, Demas 1, Dena 1, Dena 2, and Wilis were grouped as tolerant to intercropping with maize. Among these, Derap 1 was the most tolerant variety.
