Abstract

An experiment was conducted on integration of Trichoderma, Pseudomonas and fungicides for the control of Collar rot disease of Chickpea during 2013–14 and 2014–15. Results indicated that the most effective treatment was Trichoderma harzianum @ 8q/ha–1 (Soil) + Hexaconazole @ 3ml/kg–1 seed with minimum mortality (4.30 and 2.25%) which was at par with treatment Pseudomonas fluorescens @ 8q/ha–1 (Soil) + Hexaconazole @ 3ml/kg–1 seed (5.80 and 2.59%) and Trichoderma harzianum @ 8q/ha–1 (Soil)+Tubeconazole @ 3ml/kg–1 seed (6.15 and 4.09%) whereas maximum mortality 15.70 and 12.35%) was recorded in control plot. Maximum no. of pods per plant (41.30 and 49.75) was recorded in treatment T7 = Trichoderma harzianum @ 8q/ha–1 (Soil) + Hexaconazole @ 3ml/kg–1 seed which was at par with T8= Pseudomonas fluorescens @ 8q/ha–1 (Soil) + Hexaconazole @ 3ml/kg–1 (38.7 and 45.95) and significantly superior over rest of the treatment. In case of grain yield highest grain yield was increased in treatment T7 = Trichoderma harzianum @ 8q/ha–1 (Soil) + Hexaconazole @ 3ml/kg–1 seed (44.85%) followed by T8= Pseudomonas fluorescens @ 8q/ha–1 (Soil) + Hexaconazole @ 3ml/kg–1 (43.61%) and T10= Pseudomonas fluorescens @ 8q/ha–1 (Soil) + Tubeconazole @ 3ml/kg–1 seed (29.63%).

Trichoderma harzianum @ 8q/ha–1 (Soil)+Hexaconazole @ 3ml/kg–1 seed and Pseudomonas fluorescens @ 8q/ha–1 (Soil)+Hexaconazole @ 3ml/kg–1 was found most effective treatment for the control of collar rot of chickpea under field condition. As compare to alone application Trichoderma harzianum or Pseudomonas fluorescens or Hexaconazole integrated application of Trichoderma harzianum or Pseudomonas fluorescens and Hexaconazole showing minimum mortality and maximum plan growth and yield of chickpea under field condition.
