Symbiotic N2-Fixation Estimated by the 15N Tracer Technique and Growth of Pueraria phaseoloides (Roxb.) Benth. Inoculated with Bradyrhizobium Strain in Field Conditions

<div>Sources and amount of plant N (g/m2) harvested per treatment during the four-month experiment period. Ndfs = nitrogen derived from soil, Ndff = nitrogen derived from fertilizer, and Ndfa = nitrogen derived from atmosphere. IP = inoculated Pueraria, NIP = noninoculated Pueraria. In a column, values correspond to the amount of N (g/m2) per N source (soil, fertilizer, and atmosphere). One-way ANOVA using CropStat ver. 7.2 was applied to the same N source for IP, NIP, and Ipomoea and no significant difference was observed except for Ndfa between IP and NIP with different letters.</div>
