Abstract: (209 Views)
This research aims to investigate the effect of potassium and zinc fertilizers management on the quantitative and qualitative traits of rainfed wheat with six fertilizer treatments including, T1 or control (Application of all chemical fertilizers based on soil testing except potassium and zinc), T2 (Application of all potassium fertilizers from potassium-sulfate, based on soil testing in autumn), T3 (Application of 33% potassium-sulfate in fall and 67% remaining from potassium-sulfate solution containing zinc chelate in spring), T4 (Application of all zinc fertilizer from zinc-sulfate source based on soil testing in autumn), T5 (Application of all potassium-sulfate and zinc-sulfate based on soil testing in autumn), T6 (Application of 33% of potassium-sulfate and zinc-sulfate in autumn and the remaining 67% from the source of potassium-sulfate solution containing zinc-chelate in spring) was done in 3 replications and in a randomized complete block design (RBCD), during 2021-2022. The results showed that the highest leaf area index (LAI) (45.25 square centimeters) and the highest grain protein content (14.65%), grain yield (4472 kg. ha-1), potassium concentration in the grain (4880 mg.kg-1) and zinc concentration in the grain (34.60 mg.kg-1 ) were the sixth treatments. The highest Proline (568 µg. g-1 FW) and Glycine Betaine contents (3.85 µg. g-1 FW) were the fourth and sixth treatments, respectively. Considering the results and the significant effect of the treatments on the performance indicators, it is recommended to use potassium sulfate and zinc sulfate simultaneously before planting as preside-dressing applications during spring rains in rainfed wheat.
