An experiment to determine the effect of stem number per plant and media container on the growth and yield of sweet pepper (Capsicum annuum var. grossum L.) was conducted at the Indonesian Vegetable Research Institute (IVEGRI), Lembang (1250 m a.s.l.), West Java from May 2006 to February 2007. Two factor treatments i.e., 1) number of stems per plant (2, 3 and 4 stems) and 2) media container (Polybag-10 L of media and Slab-16 L of media) were arranged in a randomized complete block design with three replications. Burned rice husk was used as the growing media. The 2 and 3 stems treatments were carried out in two media containers i.e., polybag and slab, while the 4 stems treatment was only in polybag. The stem density was kept at 8.3 stems m-2 for all treatments. The results of the experiment indicated that the sweet pepper plants with 4 stems had a 3 kg m-2 lower yields compared to plants with 2 or 3 stems per plant. The yields of fruits in class >200 g in plants with 4 stems was also lower compared to the weight yield of plants with 2 and 3 stems per plant. No significant differences in terms of weight yields of fruits in class >200 g were found between plants with 2 stems and with 3 stems per plant. In terms of media container, the plants grown on polybag tended to have a higher total yields and yield of fruits in class >200 g compared to yields of plants grown on slab, however, the differences were not significant. Production of sweet pepper using 3 stems per plant and polybag container could be recommended as alternatives in growing sweet pepper.
