Other claims from this paper (19)
- Observation Eleven fungal isolates from chickpea roots were identified as Rhizoctonia solani, Fusarium solani and Sclerotinia sclerotiorum.
- Observation The isolated fungi proved pathogenic on chickpea cultivar Giza 3.
- Observation Chickpea cultivar Giza 1 was the most resistant to infection by the tested fungi.
- Observation Chickpea cultivar Giza 531 ranked after Giza 1 in resistance to the tested fungi.
- Observation The other tested chickpea cultivars were highly susceptible to infection by the tested fungi.
- Observation The response of chickpea cultivars to infection by the tested fungi was significantly varied.
- Intervention effect Trichoderma harzianum THM4 was the most antagonistic isolate to the tested fungi in vitro.
- Observation The other isolates were moderate or weak antagonists in vitro.
- Intervention effect Seed treatment with the antagonistic isolates significantly reduced damping-off, root and stem rot diseases in chickpea under greenhouse conditions.
- Intervention effect T. viride (TVM2) and B. megaterium (BMM5) proved the most effective isolates for controlling the diseases of chickpea.
- Intervention effect Under field conditions, all tested antagonistic isolates significantly reduced damping-off, root and stem rot in chickpea.
- Intervention effect T. viride (TVM2) and B. megaterium (BMM5) gave the highest reduction of damping-off, root and stem rot in all sowing dates under field conditions.
- Intervention effect Sowing treated seeds in the first of November gave the highest protection against root diseases in chickpea.
- Association The reduction in damping-off, root and stem rot severity was significantly reflected in increased chickpea seed yield.
- Intervention effect Seed treated with T. viride (TVM2) gave the highest chickpea seed yield in all sowing dates.
- Intervention effect Seed treated with B. megaterium (TVM5) gave the next highest chickpea seed yield, after T. viride (TVM2).
- Intervention effect First of November was the best sowing date for chickpea seed yield per feddan.
- Intervention effect The antagonistic isolates from chickpea rhizosphere were more active than the commercial biocide Rhizo-N in reducing chickpea root diseases in greenhouse and field conditions.
- Intervention effect The antagonistic isolates from chickpea rhizosphere increased chickpea seed yield more than the commercial biocide Rhizo-N in greenhouse and field conditions.
