Comparing the effects of growing conditions on simulated Ethiopian tef and wheat yields

Tef and wheat are staple grains in Ethiopia and are an important part of Ethiopian food security. The DSSAT NWheat and DSSAT Tef models were used to examine the effects of nitrogen fertilizer, planting date, and atmospheric CO2 on tef and wheat grain yields across four locations in Ethiopia and a 30-year time period. Observed wheat yields were consistently higher than observed tef yields, but the models showed that tef could outproduce wheat in...
