ABSTRACT
The life cycle and pathogenicity of root-knot nematode (Meloidogyne incognita) studied on Capsicum under polyhouse as well as screen house conditions for comparision. Nematode development was observed faster under polyhouse condition (35 days) as compared to screen-house (40 days). The pathogenicity of root-knot nematode at the different inoculum levels viz., 0, 10, 100, 1,000 and 10,000 J2 of Meloidogyne incognita /pot resulted into significant reduction in plant growth parameters at pathogenic level of nematode at and above 1,000 J2 inoculum level under both the conditions but plant growth parameters like shoot length (37.7 cm), fresh shoot weight (10 g), dry shoot weight(3 g), fresh root weight(9.3 g), dry root weight (2.9 g) and nematode reproduction parameters viz. number of galls per root system, no. of egg masses per root system and final nematodes population was recorded higher under polyhouse conditions due to optimum condition for both, plant and nematode.
Key words: Polyhouse, screen house, root-knot nematode, Capsicum, life cycle, pathogenicity and growth parameters.
