Cereal Nitrogen Use Efficiency in Sub Saharan Africa

47 countries in SSA
wheat (Triticum aestivum)
corn (Zea mays)
rice (Oryza sativa)
sorghum (Sorghum bicolor)
millet (Pennisetum glaucum)
oat (Avena sativa)
rye (Secale cereale)

Improving Nitrogen Use Efficiency for Cereal Production  Agron. J. 91:357-363 (pdf)

Objectives:  To document cereal N use efficiency in SSA, and to delineate potential needs for improving NUE and production.

Issues:  Climatic regions, NUE in the 10 poorest, versus rest of SSA. Only inorganic versus organic? 

"discuss organic N additions" that would not be included in our computations.
