ABSTRACT
Out of four antagonists tested, Trichoderma harzianum showed significantly maximum growth inhibition (76.19%) and grew over the F. oxysporum f.sp. ciceri colonies followed by T. viride as 72.05 per cent growth inhibition. In field condition all the bio-agents were found significantly superior in minimizing the disease over control. Trichoderma harzianum@ 6g/kg seed was found most effective, maximum seed germination(70.00 and 69.25 per cent ) and lowest disease incidence of 18.51 and 19.58 per cent as against 42.26 and 44.08 per cent in check during 2014-15 and 2015-16, respectively. Groundnut cake amendment was found most effective in reducing the disease during both the years of testing. The incidence was noted 39.98 and 41.00 per cent as compared to 56.50 and 63.88 per cent in control (unamended soil) during 2014-15 and 2015-16, respectively. Incidence of wilt decreased progressively as the planting of chickpea delayed, the minimum disease incidence (40.00 and 41.00 per cent) being in the plants sown on 25th November during 2014-15 and 2015-16. An increasing trend of disease was observed with the increased interval of irrigation during both the years of experimentation. Applying irrigation at 6-days interval resulted maximum disease incidence of wilt in 2014-15 and 2015-16.
