Abstract
This study was conducted to determine the effects of soil moisture on wilt and root rot of chickpea (Cicer arietinum), caused by Fusarium oxysporum f. sp. ciceri, F. solani f. sp. pisi, Pythium ultimum, and Thielaviopsis basicola. Three soil matric potential regimes (high =-40 to -20 kPa, medium =-260 to -40 kPa, low =-1,060 to -260 kPa) were used. Wilt and root rot increased with decreased soil matric potential, as did rhizosphere populations of each pathogen when present in soil alone or in various pathogen combinations (.)
