Aims: Snap bean (Phaseolus vulgaris L.) productivity is low in Rwanda. Investigations were carried out to assess the productivity of Snap bean using pot experiments. Methodology: The experiment was laid out in a completely randomized design with seven (7) treatments: Compost (T0), Cow manure (T1), Sheep manure (T2), Compost with diammonium phosphate (DAP), DAP alone (T3), Cow manure with DAP (T4), Sheep manure with DAP (T5) and control (T6) on Andisol and Oxisol replicated three (3) times. Results: The results showed that the pod yield was the highest in Andisol (2.39 tha-1) and the application of sheep manure significantly (P<.001) increased the leaf area, the number of leaves (P = .01) and the plant height (P= .
