Abstract: Common bean (Phaseolus vulgaris L.) is an important cash crop and protein source for farmers in many parts of Ethiopia. However, its production is limited by phosphorus fertilizer. Therefore, field experiment was conducted at the Arba Minch farm field the main rain season of 2011 to investigate the responses of common bean to different levels of phosphorus fertilizer and its effect on growth, dry matter yield and yield component of the crop. Five phosphorus rates (0, 10, 20, 30 and 40kg ha-1) were used as treatments. Red Wolaita common bean variety was used as planting material. Recommended rate of N (60 kg/ha) was applied to all treatments. The experiment was laid out in a randomized complete block design with three replications. The effect of phosphorus was significantly increased dry matter yield, yield components and growth parameters such as leaf area and number of branches per plant, whereas its effect was not significant on plant height. Based on result obtained, application of 20P kgha-1is recommended for better production of common bean at Arba Minch and similar areas which have the same soil property.
