Groundnut is an important food, feed and cash crop in Eastern Africa but in Kenya it has a yield gap of 2.5 t ha-l and this is attributed to low soil fertility, diseases, poor seed quality and poor husbandry practices. Soil exhaustion being ranked as the major groundnut production constraint in Sub Saharan Africa and particularly in Western Kenya it was necessary to evaluate the response of growing high yielding and disease tolerant (groundnut rosette virus disease) varieties with the use of various fertilizer types and rates. This would ensure increased productivity for the smallholder farmers who predominantly produce the crop at a profitable production regime. On-station experiments (fertilizer types and rates) were conducted in two sites, which included Kenya' Agricultural Research Institute (KARl) site at Alupe in Busia district and Ministry of Agriculture's Agricultural Training Centre (ATC) site at Siaya district during the long rain (March - July 2007).
