The intercropping system with the right dose of phosphorus will show higher yields than the monoculture planting system. The study was carried out with the aim of: (i) comparing crop yields between intercropping and monoculture planting systems, (ii) comparing the efficiency of land use of each planting system, and (iii) phosphorus doses which provide the highest yield for each cropping system. The study was conducted at the Experimental Garden of the Faculty of Agriculture, University of Sultan Ageng Tirtayasa Cikuya Karang Kitri District Serang, starting from April to July 2019. The experiment used a factorial randomized block design. The first factor is the planting system consisting of three levels, namely the system of soybean monoculture planting, maize monoculture planting system, and intercropping system of soybean+corn. The second factor is the dose of phosphorus fertilizer consisting of two levels, namely 25 kg.ha −1 and 100 kg.ha −1 . Each treatment combination was repeated three times. To find out the purpose of the study used the Land Equity Ratio (LER) indicator and Variant Analysis of observational data which included: plant height, number of leaves, weight per plant, crop weight per plot and seed dry weight. The plant growth with corn monoculture is better than intercropping system. The yield of plants with intercropping systems is higher than that of monoculture systems. Plant yields in both cropping systems (intercropping and monoculture) were higher by giving phosphorus doses of 100 kg.ha −1 compared to 25 kg.ha −1 .
