This study investigates the use of chabazitic zeolite as a soil amendment to enhance the growth and yield of Fragaria × ananassa (strawberry). Recognized for its high cation-exchange capacity and excellent water retention properties, chabazitic zeolite was incorporated into sandy loam soil at four concentrations: 0% (control), 2.5%, 5%, and 10% w/w. Over a 90-day period in a greenhouse, growth metrics including plant height, leaf number, chlorophyll content, and fruit production were evaluated. Additionally, soil moisture levels and macronutrient availability (N, P, K) were monitored. Results demonstrated significant improvements in plant height, foliage development, chlorophyll content, and fruit yield at the 5% zeolite level. Compared to the control, this treatment increased fruit yield by 32%, improved leaf count by 25%, and enhanced chlorophyll content by 15%. Soil analysis revealed improved moisture retention and higher nutrient concentrations in the rhizosphere, promoting better nutrient uptake. However, a decline in plant performance at the 10% level suggests that excessive zeolite may reduce soil porosity, hindering root development and gas exchange. These findings highlight the potential of chabazitic zeolite to improve water and nutrient use efficiency in strawberry cultivation. Specifically, a 5% amendment was identified as the most effective dose for optimizing plant physiological performance and maximizing yield. This approach supports sustainable agriculture practices by reducing reliance on irrigation and fertilizers, and could be particularly beneficial in regions facing water scarcity and soil degradation.
