Abstract

Pot experiment was conducted to find out effective management of root-knot nematode, M. incognita in potato cv. Lady Rosseta during November 2017 to February 2018 at department of plant nematology, C.P. College of Agriculture, S.D.A.U., Sardarkrushinagar. Pots containing 10 kg infested soil having initial nematode population of 120 J2/100 g soil with different treatments viz., organic amendments (poultry manure, castor cake), bio-control agents (Purpureocillium lilacinum and Pseudomonas fluorescens) alone and in combination with the organic amendments and carbofuran 3G nematicide alone. After seventy five days of germination, recorded observations revealed that maximum increase in plant growth parameters were recorded in combined application with poultry manure (22.30 g pot-1) enriched with P. lilacinum 106 cfu g-1 (0.022 g pot-1). Among alone treatments (without combination of organic amendments and bio-agents) maximum increase in plant growth parameters was recorded in the treatment with poultry manure. Whereas, lowest root-knot index on root as well as tuber and number of galls plant-1 root (1 g) were observed in treatment with poultry manure enriched with P. lilacinum 106 cfu g-1. Integrated management of M. incognita in potato revealed significant reduction in nematode population parametersin all the treatments compared to infected check. Maximum reduction in nematode population parameters was observed in treatment with poultry manure enriched with P. lilacinum 106 cfu g-1. Among alone treatments (without combination of organic amendments and bio-agents), maximum reduction in nematode population parameters was recorded in the treatment with poultry manure, but in soil nematode population and total nematode population build up this treatment was statistically at par with the treatment castor cake (4.46 g pot-1).
