A greenhouse experiment was conducted to study the suppression of Fusarium wilt in suppressive and conducive soils. The soils were rendered suppressive by addition of endophytic bacterial antagonists through seed inoculation. Conducive soil was made by soil-inoculation Fusarium oxysporum f. sp. ciceris (FOC). An average of 64% to 96.4% of plant germinated in all the ten treatments where seed bacterization with endophytic bacteria was done. In case of control (only FOC) only 26% of plants germinated and in normal control (without any treatment) 60% of the plant survived. Pseudomonas fluorescens (EN-1) treated pots amended with 100 μM Fe3+ Edta showed maximum (96.4%) germination in conducive soils. The next highest germination (88.0%) was observed in Bacillus substalis (EN-3) treated with 50μM Fe3+ Edta amended conducive soils. The number of plant surviving after 40 days was recorded in all the treatments. None of the plant survived, in pathogen treated FOC but in normal soil 35.2% of plant survived. | Chickpea survivability after endophytic seed bacterization and soil application of Fe3+ edta in green house condition
