Table 1 Relative abundance of Ureide-N (RAU) at the R7 growth stage (mean ± SD; n = 3) for the treatments: control (non-inoculated), seed inoculation at planting, and additional inoculations at V4 (fourth trifoliate) and R1 (beginning of flowering) in seven environments (Env.) (KS1, KS2, KS3, KS4, MN, SD1, and SD2).

From: Soybean yield, biological N2 fixation and seed composition responses to additional inoculation in the United States
