Abstract

The aim of this study was to evaluate the effects of mulch on irrigation management of common bean (Phaseolus vulgaris L.). The randomized block design with four replications was applied on five mulch rates: 0% (0 t/ha), 25% (2,25 t/ha), 50% (4,5 t/ha), 75% (6,75 t/ha) and 100% (9,0 t/ha). The study was set up at the Experimental Station of Embrapa – CNAF, Santo Antonio de Goias, 16°2’ south, 49° 17’ west and 820 m altitude from June to September, 1997 in a Dark – Red Latosol soil. A microsprinkle irrigation system was used. The results showed:-bean yield was not affected by mulch treatments;-the irrigation number was decreased when mulch application was higher than 50%.
