The dataset includes data from detailed field experiments across a temperature gradient at four locations along the River Nile. Measurements included plant density, aboveground biomass, anthesis and maturity dates, grain yield of spring wheat etc. Wheat was sown under full irrigation and fertilization with two planting dates. Observed data was used to test three DSSAT-Wheat models (CERES, NWHEAT and CROPSIM) to study climate change.

Some corrections:
* ASWN1101.WHA.txt has treatment no 7 and 8 while the other years and the design (ASWN1101.WHX.txt) indicates treatments 1 - 6. For ASWN1101.WHA.txt we mapped 7 to 5 and 8 to 6.
* In case of BeniSue (V2,P1) we corrected the ADAT from 89 into 59
