Effectiveness of Bradyrhizobia and Lime on Yield of Groundnuts and Maize Under Intercrop System in Acids Soils of Western Kenya
Abstract
125 words
Bradyrhizobia is the rhizobia species that fixes nitrogen in the
groundnut crop. Soil acidity is a constraint to effective
bradyrhizobia activity. Western Kenya is characterised by acid
soils and thus unconducive for bradyrhizobia activity. The aim
of this study was to select the best liming material to bring the pH
to optimum levels for effective bradyrhizobia activity and to
establish the best bradyrhizobia inoculants that fix the highest
amount of nitrogen for enhanced groundnut and maize yields.
Dolomitic lime raised pH to optimum levels and bradyrhizobia
A6w and V2w performed best in increasing both groundnut and
maize yields. This package, i.e., Dolomitic lime with either
bradyrhizobia strain A6w and V2w should be promoted in acidic
soils of western Kenya for ground nut and maize production.
