Limitation of planting area can be managed by optimizing the immature with alley cropping. The purpose of this research is to analyze the increase in crop productivity with a variety of fertilizer doses and analyze dosage used on intercrops. The experiment was conducted at KUD Tunas Muda, Siak Regency, Riau, November 2018 until March 2019. This experiment used a nested randomized complete block design (RCBD) the treatment consisted of two treatment factors, fertilization treatment as the main factor and crop treatment as a sub-plot. Fertilization treatment consisted of three levels, P1 (fertilizer recommendation), P2 (manure 5 tonsha −1 + 1/2 fertilizer recommendation) and P3 (manure 2.5 tonsha −1 + 1/2 fertilizer recommendation). The treatment of plants consisted of four levels, T1 (without the crop), T2 (soybean monoculture), T3 (intercropping corn + soyben (1:2)), T4 (monoculture corn). The intercropping pattern in oil palm plantations can increase land productivity. The soybean intercropping patterns affect yield components. The P3 treatment (2.5 tonsha −1 manure + 1/2 recommended fertilizer) is the optimum fertilizer dosage for corn and soybean cultivation in the oil palm area (TBM-1) by intercropping based on the results of the land equality ratio of 1.76.
