The World Bank estimates growth rates for the combined set of commercial and
noncommercial farms for the period 1974 to 1990 (World Bank 1993b, p. 25). Area and production
of maize are reported by the Bank to have increased by 8 and 10 percent, respectively, over the
period, with yields declining by about 2 percent. Results here, on the contrary, suggest modest
declines in maize production on commercial farms on the order of 3 to 7 percent, and modest
increases of from 1 to 6 percent in maize production on noncommercial farms. It should be noted that
the World Bank starting point for growth rate calculations is 1974, a momentary trough in output,
which may account for the high calculated rates. Again, the highly volatile nature of the data cannot
be overemphasized.
