  Product information is based on data from various trials conducted by CIMMYT in eastern Africa in 2016.

art. inoc. = artificial inoculation
DAP = Days after planting
GLS = Grey leaf spot
HD = High density (80,000 plants per ha)
LGB = Large Grain Borer
Low N = managed low nitrogen
masl = meters above sea level
MD = managed drought
MLN = Maize Lethal Necrosis
MSV = Maize Streak Virus
MW = Maize weevil
NUE = Nitrogen use efficient
OPT = Optimum management
RS = Random stress
TLB = Turcicum leaf blight
