| Abstract | ||||
| The experiments of this study were carried out to investigate how soil temperature is influenced by different soil moisture content regimes during soil solarization. The ten plots were brought to five volumetric moisture regimes (M1-M5). The moistened soils were mulched with 100-μm-thick black and transparent polyethylene covers. Maximum and minimum soil temperatures for depths of 10, 20 and 30 cm were recorded from 1 June to 30 July, 2010at Faculty of Agriculture, Omar Al-Mukhtar University, El-Beida, Libya. For black and transparent covers, the results showed that the maximum soil temperatures decreased with increasing soil moisture content. Moreover, soil solarization efficiency decreased with increasing moisture content. The higher temperatures under the M4 (0.39 and 0.37 m3/m3 at start solarization) irrigation regime resulted in faster eradication of the pathogenic fungus. | ||||
