This book describes Effect of plant densities on growth and yield of three dry beans varieties in the highlands Abardare Ranges.The study evaluated three dry beans (Chelelang, Ciankui, and Mwitemania) and recommend the best performer(s) to the farmers for commercial production. Since Chelelang and Ciankui are new varieties, little information is available for their production. Therefore, gastronomical practices that can improve their yields are of great importance. From the investigation, it is apparent that plant densities influence production across most of the cultivars. Therefore, under Abardare Highlands condition the optimum plant density the study would recommend is two seed per hill.
