ABSTRACT
Potato production is being affected by many bacterial and fungal diseases hence most farmers incur heavy pre and post-harvest losses. Among the bacterial diseases soft rot is one of the most severe disease. Soft rot is a potato disease caused by bacteria called Pectobacterium carotovora. lt is a seed borne disease and it is difficult to control. The research focuses on increasing resistance of potato to soft rot disease. The experiment was conducted at Africa University campus during the 2013/2014 season. A 3*4 plus control factorial experiment in a randomized complete block design with three replications was carried out in the field. Potato varieties and different calcium sources were the two blocking factors used. The treatments were calcium nitrate (19%ca), calcium chloride (36%ca), and calcium sulphate (22% ca). The control had no calcium. Sprouted tubers of Amethyst, Mondial and BP1 were inoculated with bacterial soft rot solution and then the inoculated tubers were planted with different calcium fertilizers. All the calcium fertilizers were applied basally. Soft rot incidences and severity was significantly low (P
