23 endemic birds
Many plant genetic resources
Blue Nile Water Falls
Negash Mosque- 2000 yrs old
Sofamar Natural cave
Axum Stelle- > 2000 yrs old
Lalibela rock hewn churches-built in the 12th C.
Axum Zion- the oldest church
Fasilede Palace –built in 16th C
To calibrate and evaluate CROPGRO-drybean, chickpea and cowpea under three water regimes in a semi-arid tropical environment
Table 1. Calibrated genetic coefficients of drybean, chickpea, cowpea using data from a well-irrigated experiment
1. Soil water
2. Days to flowering (dap)
3. Physiological maturity
4. Grain yield (kg ha-1)
5. Relative yield reduction
5. Simulated WSF vs. Measured LWP
