Rate and method of nitrogen fertilizer application for sesame production were studied in sandy loam soil in Sakon Nakhon Chachoengsao, Khon Kaen and Ratchaburi provinces in 1990-1991. Treatment consisted of three rates of nitrogen which were 4 8 12 kg N/rai and three methods of nitrogen fertilization: 1) basal underneath in planting row, 2) sidedressing after planting 20 days, 3) split application: 1/2 N basal and 1/2 N sidedressing after planting 20 days, phosphate and potash fertilizer were applied at the rate of 8 P2O5 and 4 K2O kg/rai, respectively. Result from the experiment showed that there were no statistically significant difference in sesame yield as the effect of nitrogen rate and method of application.
