Influence of Verticillium dahliae Infested Peanut Residue on Wilt Development in Subsequent Cotton
Figure 1
Effect of infested peanut residue rates on inoculum density of Verticillium dahliae in soil (microsclerotia/cm3). 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. Soil samples collected in February 2008 were void of V. dahliae inoculum prior to artificial incorporation of infested peanut residue. Linear quadratic equation was used to calculate intercept (), slope (a) and curvature (b).
