Extension

Our long term goal is to develop effective strategic management approaches for diversification and intensification of SGP cropping systems. We are evaluating novel crops and crop rotation systems, crop productivity, and water use and precipitation-use efficiency.

Evaluating novel crops and crop rotation systems

Evaluation of novel crop and rotation in two locations in KS. Data from the experiments described above will be collected at two-week intervals during the growing seasons beginning two weeks after planting.

Greenhouse

Water use and precipitation-use efficiency

Site-specific weather data will be used to develop water budgets. These water budgets will allow us to estimate the impacts of drought stress on the crops and to calculate the precipitation use efficiency.

Water Droplets

Calibration and validation of models

Field data related to crop growth will be collected and utilized to adjust APSIM or DSSAT models for predicting biomass and yield at the system-scale.
