One of the solutions to fulfil the demand is optimizing large area of land between oil palm before the fused canopy. This study aimed to determine the potential of soybean as ground cover plant and intercrop in immature oil palm plantation and to obtain the information on soybean varieties that have been developed as added value for farmers income (RC ratio). The study was conducted in Tanah Laut district, South Kalimantan province. The treatments used a new superior variety namely Anjasmoro, Dena 1 and Grobogan. As ground cover plant, soybean was planted when oil palm plantation was under 3.5 years. The result showed that using recommended fertilizers 40 days after planting, soybean has been able to cover 98%, 95%, and 93%. Until the 50th day, the ground will be covered 100%. Whereas using fertilizers done by farmers, the land cover was 93%, 94%, and 93%, and on the 50th day, it also reached 100%. The result of an economic analysis based on the R/C was profitable with the value of 1.42 by applying fertilizer according to cropping calendar recomendations.
