Our laboratory is working on the development of sustainable cultivation practices with a focus on field and plantation crops, rhizosphere management, and the development of high-value fruit and medicinal plant systems. We investigate plant–soil–microbe interactions in diverse agroecosystems, aiming to enhance nutrient cycling, soil health, and crop productivity under changing climatic conditions. A major thrust of our work lies in rhizosphere ecology and nutrient management, where we explore natural and organic amendments to improve resource-use efficiency, stress resilience, and carbon sequestration. We integrate these approaches with plantation crops and high-value fruit species, designing innovative cultivation models that optimize productivity while conserving natural resources.
