There was an observation on the influence of a plant growth regulator (NAA) and a foliar fertilizer (18-33-18 + Trace Elements) for mungbeans grown on four soils in a greenhouse of the Chainat Field Crops Research Center. Plants were sprayed in the evening 4 times at the 14, 21, 28 and 38 days of age. A combination of 15 gm. of 12-24-12 granule fertilizer and 2.40 kg/soil was to be the reference pot. Mungbean seed yields were collected at the 56th days. There was no significantly different effect between NAA (12 ppm conc.), foliar fertilizer (2250 ppm conc.) and the control pot which received no fertilizer for Pakchong (Pc), Donchadi (Dc) and Sanphaya (Sa) soils. These yields were lower than the reference pot by 295 %, 120 %, 75 % and 38 % for Pc, Dc, Cn and Sa soils, respectively
