Sclerotium rolfsii is a soil-borne plant pathogen that causes root diseases in hundreds of plant species. It also causes collar rot disease in chickpea (Cicer arietinum L.). The present pot study was carried out to investigate the effect of soil amendment with dry biomass of a weed Chenopodium album L. and two antagonistic fungi, namely Trichoderma harzianum and T. viride, on growth and yield of chickpea variety Noor 2009 in soil infected with S. rolfsii. The pathogen-contaminated soil was amended either with 1, 2, or 3% C. album dry biomass, T. harzianum, and T. viride alone, or combinations of either of the two Trichoderma species and plant dry biomass. The lowest shoot and root dry biomass and grain yield of chickpea were recorded in S. rolfsii inoculation alone without any soil amendment (positive control). Plant growth and yield were significantly and gradually increased over positive control with an increase in C. album dry biomass application in the soil. Likewise, soil application of either of the two Trichoderma species significantly enhanced plant growth and yield over positive control under biotic stress of S. rolfsii. Combined application of either T. harzianum or T. viride with 3% dry biomass of C. album also proved highly effective in alleviating biotic stress of S. rolfsii on growth and yield of chickpea.

藜麦干生物量和两种木霉属土壤改良剂对鹰嘴豆生长的影响。2009年Noor 2009在Sclerotium rolfsii污染的土壤中

菌核菌是土壤传播的植物病原体，可导致数百种植物的根部病害。它还会引起鹰嘴豆（Cicer arietinum L.）的衣领腐烂病。本盆栽研究旨在研究杂草藜麦和两种拮抗性真菌哈茨木霉和特立木霉的干燥生物量对土壤的改良对鹰嘴豆品种Noor 2009在感染土壤中生长和产量的影响。罗非鱼 用1、2％或3％的C. Album干生物量，Harzianum和T. viride单独或两种木霉属物种和植物干生物量的组合修正病原体污染的土壤。在不加任何土壤改良剂（阳性对照）的情况下，单独接种S. rolfsii时鹰嘴豆的最低芽和根部干生物量及籽粒产量均最低。随着土壤中C. album干生物量的增加，植物的生长和产量显着并逐渐超过阳性对照。同样，在罗勒链球菌生物胁迫下，两种木霉菌种中任何一种的土壤施用均显着增强了植物的生长和产量，超过了阳性对照。哈茨木霉或藜科木霉与3％的干衣藻的干生物量的组合施用也被证明在减轻罗氏链球菌对鹰嘴豆生长和产量的生物胁迫方面非常有效。
