Due to low A. flavus infection and low aflatoxin contamination under the natural condition in 1988, Inoculation methods of A. flavus to study the response of aflatoxin contamination to nitrogen application was employed since 1989. A silk channel and a pin-bar method were tested. It was 3 to 4 percent in average of A. flavus infections by the silk channel method. Average 61 and 98 percent of infections in 1990 and in 1991 were obtained by the pin-bar method. Significant differences in nitrogen applications were not observed in control and silk channel inoculation. Although significantly was not tested in 1990, 2369ppb, 1293ppb, 1375ppb and 129ppb in N:0, N:10, N:20 and N:30 (kgN/rai) plots were seen. In 1991, average aflatoxin in nitrogen plots were 1962ppb, 2190ppb, 1408ppb and 1563ppb. Significant difference on aflatoxin contamination between low Nitrogen (N:0 and N:10) and high nitrogen (N:20 and N:30) applications was observed.
