Figure 1. Yield of maize in 32 farmers’ paired-plot trials in NWFP, Pakistan. Data were pooled<br />
from 1999 (11 farmers), 2000 (15 farmers) and 2001 (6 farmers) and are ordered by the yield of the<br />
non-primed plot (light bars) in each trial. Overall mean yield (non-primed) = 1.23 t ha -1 ; overall<br />
mean yield (primed) = 1.71 t ha -1 .
