Fig. 5. Soybean cyst nematode mean cyst population density [log₁₀ (cysts 100 cm^–3 of soil + 1)] ± standard error by soil type in Field A (open circles) and in Field B (closed circles) at (A) planting 1999, (B) harvest 1999, (C) planting 2000, and (D) harvest 2000. Soil types are sandy clay loam (SCL), sandy loam (SL), loamy sand (LS), and loam (L). Means with the same letter were not significantly different (protected LSD, 0.05 significance level).
