This study examined the potential economic returns of using four different sources of nitrogen on `calabaza' pumpkins, a low moisture variety consumed as starch by many foreign nationals. Yields were 12.4, 12.6, 8.2 and 9.5 kg/plant for ammonium nitrate, sodium nitrate, ammonium sulfate and urea, respectively. Assuming 1989 farm gate prices in Alabama and other appropriate cost for vaious inputs used, the estimated return at $0.30/lb of pumpkin was $10,003, $10,115, $6,105 and $7,371/acre for different sources of nitrogen, respectively. The relatively higher return from sodium nitrate use explains the use of this source of nitrogen on rented land. A sensitivity analysis of the enterprise budgets shows a breakeven price between $0.02 and $0.10/lb.
