Abstract
The present field experiment was conducted to determine the efficacy of consortium of different bio-agents viz., Psuedomonas fluorescens + Trichoderma harzianum + Bacillus megatherium, organic amendments viz., neem cake, poultry manure and nematicides viz., carbosulfan, carbofuran and fluensulfone for the management of M. graminicola under direct-seeded condition during kharif 2019-20 at the University of Agricultural and Horticultural Sciences, Shivamogga. The results revealed that all the treatments were significantly superior over the untreated check with respect to plant growth parameters and nematode population. However, the plots treated with fluensulfone at 3g/plot was found to be the best treatment as it recorded highest plant height (78.87 cm), root length (18.90 cm) with lowest RKI (2.0), maximum grain yield (36.87 q/ha) and least nematode population (199.00/200g soil) followed by the consortium of bioagents P. fluorescens + T. harzianum + B. megatherium at 20g/m2, carbofuran 3G at 9.9g/ m2, carbosulfan 25 EC at 0.1%, neem cake at 100g/m2 and poultry manure at 100g/m2 respectively.
