DSSAT · Crop ModelingPrecision Nitrogen Management in Spring Rice
Chitwan, Nepal
The Problem
Farmers in Chitwan, Nepal were applying nitrogen fertilizers based on blanket recommendations, leading to inefficient resource use and environmental impact.
Approach
Applied DSSAT decision support tools to model nitrogen dynamics in spring rice (Oryza sativa L.) across multiple management scenarios.
Tools Used
Results
Identified optimized nitrogen application rates that could reduce input costs by an estimated 15-20% while maintaining yield levels.
Impact
Provided evidence-based recommendations for precision nitrogen management adaptable to smallholder farming systems in the Terai region.
Development · PythonDSSAT Graphical Visualization GB2
University of Florida
The Problem
Existing DSSAT visualization tools had limited interactivity and did not fully support the latest model outputs in v4.8.6.
Approach
Developing Graphical Visualization GB2 with enhanced data visualization capabilities, modern UI, and improved data processing.
Tools Used
Results
Creating a more intuitive and powerful tool for researchers to analyze and visualize crop model outputs.
Impact
Enhancing data visualization capabilities for the global DSSAT research community used by researchers in 100+ countries.
