Influence of Verticillium dahliae Infested Peanut Residue on Wilt Development in Subsequent Cotton

Figure 2

Effect of infested peanut residue rates on germination of cotton seeds (%). Infested peanut residue rates 0, 370, 925, 1850, 2775, 3700, 18495, and 37000 kg/ha were log₁₀ transformed and were expressed as 0, 2.6, 3.0, 3.3, 3.4, 3.6, 4.3, and 4.6 on X-axis. Linear quadratic equation 𝑓=𝑦⁰+𝑎𝑥+𝑏𝑥² was used to calculate intercept (𝑦⁰), slope (a) and curvature (b).
