Data attained for crops during the wet season
(Table 1), are less complete. The wet season was
statistically similar to the dry season, with 19% of the
total damage occurring at ripening (confidence limits
8–30%). Farmers estimates of yield for the 1999–2000
wet season data were 10% higher than quadrat
estimates, but 42% lower for the 2002 dry season.
Based on all other data, farmers tended to underevaluate
yield by about 20% on average (Fig. 1).
Quadrat samples were assumed to be more accurate
estimates of rice yield.
