Abstract:
Role of Parthenium hystereophours on population built-up of Meloidogyne incognita on brinjal was studied. The observations recorded revealed that, number of galls soil population, egg population, total root population, total nematode population and multiplication factor of nematode was significantly lower in all the treatment in comparison to treated check. The highest soil population, egg population, total root population, total nematode population, multiplication factor and number of galls was recorded (1938.5), (577.50), (183.75), (78045.25), (15.60) and (173.50) respectively in untreated check with the minimum (536.70), (93.60), (36.25), (9932.75), (1.98) and (25.75) in treated check respectively. Among the Parthenium and compost treatments the most effective treatment for the management of root knot nematode Meloidogyne incognita was Parthenium leaf compost @ 7.5% + compost. It was followed by Parthenium leaf compost @ 5% + compost, Parthenium leaf compost @ 7.5%, Parthenium leaf compost @ 5% + compost, Parthenium leaf compost @ 5%, Parthenium compost @ 5% and compost @ recommended dose in ascending order for the management of root-knot nematode, Meloidogyne incognita. highest multiplication rate 15.60 in untreated check, 11.58, 9.70, 8.86, 8.18, 7.44, 5.95 and 3.98 with the minimum (1.98) in compost @ the recommended dose, Parthenium compost @ 5%, Parthenium leaf compost @ 5%, Parthenium compost @ 5% + compost, Parthenium leaf compost @7.5%, Parthenium leaf compost @ 5% + compost, Parthenium leaf compost @ 7.5% + compost and treated check respectively.
