Abstract Common bean (Phaseolus vulgaris) is susceptible to Zinc (Zn) deficiency. The objective of this study was to verify the influence of foliar application of Zn on irrigated bean yield in north-west Spain. The work was carried out during 1999 and 2001 in the province of León. The design was a split-plot design and the primary and secondary factors were, respectively, Zn dose (0, 50, and 100 g Zn/ha) and the number of Zn applications (1 or 2). Yield was increased with Zn foliar application to 20.74 g/plant at 50 g Zn/ha (17.0% increase) and 20.62 g/plant at 100 g Zn/ha (16.3%). However, there was no significant difference between applied Zn concentration and the number of applications. Pods per plant were increased when foliar Zn was applied (12.3% at 50 g Zn/ha and 14.5% at 100 g Zn/ha, to 12.27 and 12.52 pods/plant, respectively). The increased yield was the result of the increased number of pods/plant.
