| dc.description.abstract | The present study entitled “Pathogenicity and life cycle studies of Meloidogyne incognita in capsicum including its integrated management under protected cultivation” was carried out in the Department of Nematology, RPCAU, Pusa, Samastipur, Bihar to study the incidence and frequency of distribution of root- knot nematode, Meloidogyne incognita in Samastipur, Muzaffarpur, Darbhanga and Vaishali districts of Bihar in capsicum grown under polyhouses, pathogenicity and life cycle of M. incognita under polyhouse and management using different organic amendments. During survey, mean population density of M. incognita ranged between 1035 – 3205 nematodes per 200 cc of soil, was recorded. Maximum nematode infestation was observed in Muzaffarpur district. Pathogenicity level to cause significant loss in plant growth was recorded at initial inoculum density of 1,000 J2/plant, inverse relationship between plant growth parameter and inoculum density and direct relationship between nematode multiplication parameters and initial inoculum density was observed, maximum damage to crop was observed at highest inoculum density of 10,000 J2/plant. Meloidogyne incognita completed its life cycle from J2 to adult in 33 days, during the study temperature inside polyhouse was recorded at 10o C to 36o C. All the organic amendments when combined with Trichoderma viride @10 g/pot, have improved plant growth and yield while decreased nematode multiplication parameters. Highly significant treatment was Trichoderma viride @10 g/pot + neem cake @ 100 g/pot, which increased crop yield by 77 % compared to untreated check. | en_US |
