Maize seeds were inoculate with broth cultures containing 106±107 cfu ml
Seeds dipped in broth
alone were used as control. Separate plots were pre-
pared for each treatment (plot size = 6.75 m2) in
triplicate. The plots at each site were adjacent to
each other, and the plots for dierent treatments
were separated from each other by an adequate gap
between the plots and a raised bund (15 cm above
ground) in the middle.
