This review of past research results of fertilizer application in order to improve the yield of the major highland grain legumes in Ethiopia indicated that application of N on faba beans significantly increased grain yields. Similarly, application of P significantly increased faba bean grain yields in most trials. A highly significant increase in yield was obtained with the application of N and P fertilizers across Ethiopia. The combination of N, P and K increased faba bean grain yield by over 100. Response to fertilizer application was greater by the improved cultivars. Faba bean responded significantly when cropped after cereals and grain legumes but not after highland oilseeds. Chickpea did not respond significantly to N and P application at Debre Zeit, Adet and Ginchi. Lentil failed to show an increase of yield due to N and P applications at Ginchi and Dembi. Response to N application implied that inoculating the crop with suitable strains of Rhizobium might be an alternative for obtaining increased crop production as well as ameliorating the soil. Field peas responded to N and P applications in some places with a yield increase of over 61. But there was no significant response to N and P fertilizer at Holetta
