Adaptability of soybean cultivar and lines to intercropping with corn and artificial shading. An experiment was conducted at Bogor from April to July 1990. Treatments of the experiment were arranged in a split plot design with two replications. The main plots consisted of the cropping systems, i.e : soybean in monoculture, intercropped, with corn and under artificial shading at 33 percent shading intensity. The sub plots consisted of 28 soybean cultivars/lines. The result showed that the yield and plant height were affected by genotype, cropping systems and interaction between genotype and cropping system. The yield of soybean under intercropping with corn and artificial shading decreased 6-52 percent and 2-56 percent, respectively. The highest soybean yield under intercropping with corn and artificial shading was found on Lamp/1248-4-4 (1,1 and 1,2 t/ha), respectively. The yield of Lamp/1248-4-4 decreased only by 10 percent and 6 percent under intercropping with corn and artificial shading respectively.
