The maximum soil temperature average was increased °C by soil solarization alone at the 15 cm soil depth of soil in the first year. Soil solarization alone and in combination with CM increased the mean of maximum soil temperature by and °C respectively, at the 15 cm soil depth in the second year. Root galling caused by M. incognita in tomato plants in the soil solarization plus organic amendment plots (CM or OPW) was lower than in plots that underwent the other treatments. In addition, tomato yields in plots subjected to soil solarization and soil solarization in combination with organic amendment (CM or OPW) were similar to those in plots subjected to Dazomet and soil solarization plus half doses of Dazomet.
