Introduction. Water availability , from precipitation or watering, is an important factor for crop growth. The amount of water availability is first going to affect the growth of plant vegetative structures: roots, leaf area, production of branches, etc. The general plant performance is also affected. Therefore, the reproductive structures are affected. The objective was to define the effect of water availability on the plant structures and yield of common bean. Materials and Methods. Water amount of 189, 242, 292, 344, 394, 446, 550 and 601 mm were applied to Type I beans, sown in pots. Results. The stem dry weight, the number of seeds per pod and the weight per seed were not affected by water availability. The pod weight, pods per plant and number of seeds per plants were affected by the water availability. The 449 mm treatment produced the highest yield. Conclusion. Water availability affects bean growth.
