Abstract: A field experiment was conducted at Ummdagarsi area in Gezira state, central Sudan to study the effects of inoculation with Rhizobium and Bacillus megatherium var. Phosphaticum (BMP), phosphorus and nitrogen fertilization on yield and seed quality of chickpea plants variety Bergag. Rhizobium inoculation significantly (p<0.05) increased yield, ash, fiber, tannin and protein content of chickpea seeds. BMP inoculation significantly (p<0.05) increased ash, fiber, protein content and cookability. Rhizobium and BMP co-inoculation significantly (p<0.05) increased yield, 100 seed weight, ash, fat, protein content and cookability. Application of chemical fertilizers significantly (p<0.05) increased yield, 100 seed weight, ash, fat and protein content.
