Abstract
This study was conducted to determine the effects of foliar-applied zinc (Zn) and iron (Fe) doses on selected agronomic and yield traits of dwarf common bean (Phaseolus vulgaris L.). The experiment was established in 2025 under two distinct agro-ecological conditions in Erzincan Province using a randomized complete block design with split plots and three replications. Four increasing Zn doses (0, 0.25, 0.50, and 1%) and five Fe doses (0, 0.25, 0.50, 1, and 2%) were applied once as foliar treatments at the beginning of the flowering stage. The traits evaluated included days to flowering, number of pods per plant, pod length, number of seeds per pod, hundred-seed weight, and seed yield. The results indicated that individual applications of Zn and Fe caused statistically significant differences in the examined traits. Moreover, the combined application of Zn and Fe further enhanced these effects. Overall, the combined application of 0.5% Zn and 0.5% Fe resulted in the highest mean values for most growth and yield components. In contrast, notable reductions in the evaluated traits were observed in the control plots and at higher application doses. The location effect was found to be highly significant (p<0.01) for all parameters, indicating that plant responses to micronutrient applications were strongly influenced by environmental conditions. These findings suggest that balanced and combined foliar application of Zn and Fe, considering location-specific conditions, is an effective strategy for improving yield and yield components in common bean.
