Abstract: 

The effects of application of zinc sulfate by different methods and times on grain yield and protein content of chickpea was studied. An experiment was conducted in a completely randomized block design with a factorial arrangement of treatments (control=Zn0, soil application=Zns, foliar spray in early flowering = Znf1, foliar spray in early podding = Znf2 and their components as Zns Znf1-Zns Znf2-Znf1 Znf2-Zns Znf1 Znf2 two planting date: D1= fall and D2= spring) with three replications. Soil application of ZnSO4 was 20 kg/ha and in foliar application solution concentration was 0.2 percent. Results indicated that the effects of year, fertilizer treatments ,planting dates and their interactions on yield were significant (a=1%). The maximum yield was obtained in treatment of D1 ZnS Znf1 (soil application and one foliar spray of ZnSO4 in early flowering in fall planting) and treatment D1Zns (soil application of ZnSO4 in fall planting) with the yields of 1524 and 1522 kg/ha, respectively. Results indicated that application of zinc sulfate increased Zn uptake, grain yield and protein content by soil application at fall planting. It was also observed that in fall planting, an application of zinc sulphate in preplanting (20 kg/ha) and foliar spray in early flowering and in spring planting, and a foliar spray in early flowering could be recommended.
