Course overview

Crop yield estimates often guide seed and fertiliser procurement, irrigation allocation, food-security early warning, crop insurance, contract farming and market planning. Yet estimates can fail when weather records are incomplete, soil profiles are poorly defined, cultivar parameters are borrowed without testing, or model outputs are reported as certain predictions. Crop modelers need to connect field observations, weather data and management records to defensible projections that decision-makers can use.

This five-day course develops the technical and analytical skills required to build, calibrate, validate and apply crop simulation models for yield prediction and management decisions. Participants work with process-based modeling approaches used in DSSAT, APSIM and AquaCrop, covering weather and soil inputs, crop genotype and management files, calibration against observed data, validation metrics, sensitivity analysis and scenario design. The course also addresses seasonal climate scenarios, irrigation and nitrogen management, remote-sensing observations, district-level aggregation and communication of uncertainty.

Teaching combines focused technical briefings with guided software demonstrations, agricultural case work, group analysis and structured model interpretation. Cases reflect common decisions in commercial farming, agricultural extension, development programmes and food-security monitoring. Participants leave with a reusable crop-modeling workflow package, including input-data specifications, calibration and validation templates, scenario matrices, reporting formats and an application plan for a priority crop or production area.

The course is designed for agricultural professionals who already work with crop production data, agronomy, irrigation, climate information or agricultural programmes and need stronger methods for converting those data into documented yield forecasts and management advice.

How the course runs

Training methodology

The course uses short technical briefings followed by guided interpretation of crop-model inputs, outputs and performance diagnostics. Participants examine agricultural cases involving rainfall variability, irrigation limits, cultivar choice and nutrient management. Group work focuses on checking data quality, setting calibration priorities, interpreting validation results and comparing scenarios. Trainer-led simulations show how DSSAT, APSIM and AquaCrop represent crop growth and water stress. The final sessions convert technical results into forecast briefs, decision triggers and individual application plans.

Requirements and prerequisites

Participants should understand basic crop production concepts, including planting dates, crop stages, fertiliser, irrigation, soils and yield measurement. Experience handling agricultural datasets in spreadsheets is expected, along with confidence reading tables, charts and simple descriptive statistics. Familiarity with weather data, GIS, R or crop simulation software is useful but not required. The course explains model configuration and performance metrics from first principles. Advanced programming, prior use of DSSAT, APSIM or AquaCrop, and formal training in statistics are not required.

Frequently asked questions

Participants need basic knowledge of crop production, soils, weather and yield measurement, plus confidence using spreadsheets. Previous experience with crop-modeling software, GIS, programming or advanced statistics is not required.

Bring a laptop with spreadsheet software and, where possible, non-confidential examples of weather, soil, crop or yield data from your work. Training datasets and guided model files are supplied for the classroom work.

It suits agronomists, researchers, food-security analysts, irrigation specialists, extension managers and agribusiness planners. It is intended for professionals who need to interpret or produce crop yield predictions, rather than for participants seeking basic agronomy training.

General agronomy courses focus on crop husbandry, while precision agriculture courses commonly focus on sensors, machinery and spatial field operations. This course focuses on using weather, soil, crop and management data within simulation models to estimate yield and test future scenarios.

Participants can use the workflow to prepare model inputs, assess prediction accuracy and compare management scenarios for a priority crop or location. The reporting formats also support communication with programme managers, farm managers, procurement teams and technical partners.

The course runs from 08:30 to 16:30 each day, providing about 6.5 contact hours daily. Time is divided across model concepts, data preparation, software-guided analysis, calibration and validation, scenario work, communication and workflow planning.
