| Sumario: | Maize is the most important cereal food
crop is sub-Saharan Africa though yields are below
their potential. Among the factors which limit yield,
drought stress is one of the most pervasive. The ability
of a crop to produce grain under drought (water) stress
is governed by many factors including nematodes. The
aim of the current study was to determine the response
of drought tolerant maize inbreds to nematode attack,
understand the interaction between nematode infesta-
tion and water stress on maize growth and yield. The
study comprised three factors: optimal irrigation
against water stress, five nematode treatment condi-
tions and ten maize inbreds. Results showed irrigation
option

genotype interaction to significantly affect
growth of the maize crop from 6 weeks after planting.
Water stress favoured the reproduction of lesion
nematodes (
Pratylenchus zeae
), 50 times more than
root knot nematodes (
Meloidogyne incognita
), which
showed an increase in most inbreds only under optimal
irrigation. Inbreds ACR.SYN-W, La Posta Seq. C7,
TZL Comp1C4 and 5057 displayed resistance to
P.
zeae
and
M. incognita
under water stress, although cobMaize is the most important cereal food
