Field experiment was conducted at Khon Kaen province with the aim of studying the effect of N fertilizer and Rhizobium inoculation on nodulation and yield of groundnut cultivar Khon Kaen 60-1. The soil where the experiment took place was a loamy sandy soil, having a pH of 4.8 (1:5 H2O), 0.7 percent organic matter, 9 ppm available P and 36 ppm exchangeable K. The field was continuously cropped with non-legumes. Groundnut cultivar Khon Kaen 60-1 was given 0, 19, 38 and 56 kg/Nha as ammonium sulfate with or without rhizobia inoculation. No significant difference among N fertilizer treatments and between rhizobia inoculation treatments was observed in terms of nodule number, nodule dry weight and pod yield. It is suggested that N fertilizer and Rhizobium inoculation is not necessary in this area.
