Impact of Crop Rotation and Bio-covers on Soybean Cyst Nematode

Fig. 2. Changes in soybean cyst nematode (SCN) 0- to 15-cm over time (2004-2006) at the Research & Education Center at Milan, TN, by crop sequence (Ct = cotton, Cr = corn, S = soybean) averaged across bio-covers in 2004 (A), 2005 (B), and 2006 (C) and by bio-cover averaged across crop sequence in 2004 (D), 2005 (E), and 2006 (F). Error bars denote 95% confidence interval (±2*std. error).
