A line source with a five-band irrigation experiment was used to determined the total common bean water demand under conventional and no-tillage systems. Irrigation controlled by two tensiometer sets installed in second band parallel source. The system resulted 20% reduction as compared system. estimated based on class “A” evaporation tank overestimated for systems 11% 29%, respectively. KEY-WORDS: No-tillage; tensiometer; irrigation.
