Variety and plant population affect soybean yield. The experiment was conducted at Cikeumeuh experimental farm in the dry season 1984. The design of experiment used was randomized complete block design with four replications. The main plot treatments were three soybean varieties: No. 29, Orba and Lokon, while the subplot treatments were three levels of plant population: 200.000, 400.000, and 500.000 plants/ha. The result showed that plant height increased with increasing plant population. The crop growth rate (CGR) also showed the similar pattern. At early growth stage, the net assimilation rate (NAR) was higher and then decreasing at the later stages. The highest leaf area index (LAI) was obtained at the highest plant population
