dc.description.abstract The study was conducted to assess the effect of Rhizobium inoculation and intercropping systems on soil nutrients improvement and biological nitrogen fixation as influenced by two legumes (Phaseolus vulgaris and Dolichos lablab). To achieve this aim, the field experiments were conducted at Selian Agricultural Research Institute (SARI) for two seasons. The fertility status of the soils and their suitability for cereal/ legumes production at the experimental site was evaluated based on technical indicators of soil fertility. From the soil analytical results, the major soil fertility limitations included low soil organic matter, low total nitrogen and medium available phosphorus for season 1 hence the soils were categorized as of low fertility status and moderately suitable for cereal/ legumes production. This was opposite in season 2 due to legumes biological nitrogen fixation and incorporation of legumes crop residues into the soil as the results of the first season harvest. A randomized complete block design was used in a 3-factorial arrangement with two levels of Rhizobium (with and without rhizobia), 2 legumes (P. vulgaris and D. lablab) and 5 cropping systems. The results showed that Rhizobium inoculation was significantly (P ≤ 0.001) on nodules number per plant; nodules weight (g) and biological nitrogen fixation (kg N ha-1) in season 1 and 2. Based on these findings, it is thus recommended that, Rhizobium inoculation is the most profitable biofertilizer for soil fertility restoration. en_US
