A field experiment was conducted to study the influence of inoculation and micronutrients (Mo an.d 80) application in combination with starter nitrogen (SN) at the rate of 15 kg/ha at planting on nodulation, N uptake and dry matter yield of groudnut at the pod-filling stage on a sandy loam soil (Plinthaqua/j) in the Sudan-savana zone of Ghana. The results revealed possible presence of effective native rhizobial strains capable offorming root nodules on groudnut in the soil. Although the application of SN alone tended to reduce nodulation, total N uptake and total dry matter yield of the crop, a combination of the SN with 3 kg/ha of sodium molybdate appreciably increased nodulation and total dry matter yield, and significantly increased the total N uptake of groudnut (P=0.5). Inoculation had no significant effect on any of the parameters studied.
