Resum
The response of chickpea (Cicer arietinum) to Zn nutrition was studied in pot experiments under natural conditions using four acid soils of northwest Spain during 2007 and 2008. Five concentrations of Zn (0, 1, 2, 4 and 8 mg Zn pot�1) were added to the pots as Zn chelate. Chickpea responded to the soil Zn applications and there were highly significant differences between soils. At maturity plants fertilized with Zn had greater total dry matter production mainly due to increments in pods weight. The lowest yield (2.65 g plant�1) was obtained from 0 mg Zn pot�1, while the highest yield (3.52 g plant�1) was recorded at 4 mg Zn pot�1. The increased yields in Zn applied plants was the result of increased number of pods per plant. Furthermore, this yield component was closely correlated with the seed yield.
