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