Abstract
Investigations 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 yield
