The effects of soil temperature (10, 15, 20 and 25�C) and moisture (45% water holding capacity (WHC), 65% WHC, and flooding) on the pathogenicity of five fungi, both alone and in combinations, were investigated to determine the involvement of these fungi in a severe root rot disorder of subterranean clover in Western Australia. Fusarium avenaceum, Pythium irregulare, and Rhizoctonia solani were highly pathogenic while Fusarium oxysporum and Phoma medicaginis, particularly when used singly, were only weakly pathogenic. Compared with individual fungi, fungal combinations increased the severity of root disease and decreased plant survival and plant fresh weight. While the fungi investigated caused root rot over the range of soil temperatures and moisture conditions of this investigation, the most severe root rot occurred at 10�C, with less at 15 and 25�C, and least at 20�C. Temperature had a marked effect on the disease severity and its effect varied with individual fungi and their combinations, in particular, combinations involving P. irregulare (severest root rot at 10 and 15�C). The most severe root rotting, compared with the control, occurred at 65% WHC, with less at 45% WHC, and least under flooding conditions. There was often a significant interaction between temperature and moisture for the various fungi and fungal combinations tested.

In a field experiment yields of barley were lower, regardless of moisture, when the mean minimal soil temperature was near 27 °C than near 9 °C or 18 °C. The highest yields were obtained at 18 °C. Application of fertilizer increased final yields and uptake of N, P, and K at 9 °C and 18 °C but not at 27 °C. At 9 °C and 18 °C response to added fertilizer occurred as the moisture content of the soil was raised from near the wilting point to field capacity. During the early stages of growth an increase either in temperature or moisture increased the uptake of N, P, and K. Percentage P in the plant material during early growth was related to yield near heading stage when soil temperature conditions were considered. The protein content of the grain was increased at the higher soil temperature for all moisture conditions.
