Background and Objective: Chickpea (Cicer arietinum L.) occupies the largest cultivated area among legumes in Iran. Nutrition management through the application of organic and mineral fertilizers can significantly increase yield. Therefore, this research was conducted with the aim of investigating the efficiency of soil application and foliar spraying of zinc sulfate and humic acid in dryland chickpea production.
Methods: This field experiment was carried out using a split plot design within a randomized complete block framework. The land was divided into 4 blocks and each block had 28 plots. The main plots included the control, soil application of zinc sulfate, humic acid, and zinc sulfate + humic acid. The sub-plots included the control (without foliar application), foliar spraying of zinc sulfate, humic acid, and zinc sulfate + humic acid in a single application at pod formation and in two applications before and after flowering.
Results: The highest pod no. per plant (12.5), grain no. per pod (1.1), plant height (67.8 cm), 100-grain weight (34.9 g), root dry weight (12.3 g), node dry weight (4.6 g), nodule no. per root (11.4), grain yield (1431 kg/ha), biological yield (3365 kg/ha), grain nitrogen (3.6%), and grain protein (22.5%) were achieved through soil application and foliar spraying of zinc sulfate and humic acid before and after flowering.
Conclusion: Among the soil application treatments, the application of zinc sulfate + humic acid, and among the foliar spraying treatments, two-stage application of zinc sulfate + humic acid before and after flowering, had the greatest impact on the yield and yield components of chickpeas. Grain yield in these treatments increased by 34% and 55%, respectively, and biological yield increased by 30% and 32%, respectively, compared to the control.
