Growth and yield responses of barley and cowpea to irrigation management in salt-affected environment: A coupled experimental modelling approach

Objectives

1. Optimize irrigation management for barley and cowpea in a marginal environment affected by salinity
2. Determine the impact of deficit irrigation and salinity stress on the growth and yield of barley and cowpea
3. Calibrate and evaluate process-based crop models using field data
4. Determine the long-term effects of irrigating with saline water on soil salinity using the calibrated model under historical/future weather scenarios
