Abstract

 This study investigates the potential to reduce the recommended mineral nitrogen dose (NRD) for wheat without compromising yield by utilizing zeolite amendment and potassium silicate spraying. The experiment included main plot treatments of 100%, 80%, and 60% NRD (ammonium nitrate, 33%N). Subplots incorporated zeolite at a rate of 1.2 ton fed-1 (applied or not), and sub-subplots involved potassium silicate spraying at 0.0, 750, and 1000 mg L-1. Key measurements included plant height, fresh and dry weights, leaf area, chlorophyll content, grain and straw yield, carbohydrates, protein content, and soil NPK levels. Results demonstrated that applying zeolite with 80% NRD and potassium silicate at 1000 mg/L outperformed the traditional 100% NRD application in terms of plant growth and yield parameters. Additionally, the zeolite amendment significantly enhanced soil NPK availability. These findings suggest that reducing the NRD to 80% when combined with zeolite and potassium silicate can maintain or even improve wheat productivity while enhancing soil fertility. Generally, integrating zeolite amendments and optimal potassium silicate application can effectively reduce nitrogen fertilizer usage without reducing wheat yield. Future research should focus on long-term impacts and the economic feasibility of this approach.
