dc.description.abstractInvestigations were carried out for two years each at Samaru in the Northern Guinea and Mokwa in the Southern Guinea savannah to observe the response of groundnut (Arachis hypogaea L.) to varying levels of phosphorus (6, 16 and 24kg P ha -1 ), potassium (0, 20 and 40kg ha -1 ) and boron (0.0 and 0.5kg 0 ha - 1 ) . At Samaru, increasing the level of phosphorus from 8kg to 16 and 24kg P ha-1 enhanced pod yield by an average of 23 and 16%, respectively. Other yield attributes such as mature pods per plont, shelling percentage and kernel weight were only slightly increased up to 24kg P ha-1 . In Mokwa, the application of 16kg P ha -1 appeared adequate for optimum groundnut production. The addition of potassium fertilizer generally did not result in increased pod production. However, at Mokwa where the level of soil potassium was relatively low there was a tendency for increased pod yield in the presence of added potassium fertilizer. Application of boron had no effect on groundnut production except in 1984 at Mokwa where the use of 0.5kg 0 ha-1 significantly increased the haulm yielden_US
