Abstract:

The efficacious nature of organic matter such as Calotropis procera and bio-inoculants like Glomus fasciculatum and Trichoderma viride was determined in okra cultivar �??Arka Anamika�?? when inoculated singly as well as concomitantly for the ecofriendly management of the root-knot nematode, Meloidogyne incognita in terms of growth parameters such as plant height, fresh as well as dry weights, number of flowers and fruits/plant, percent pollen fertility, chlorophyll content and mycorrhization. Combined applications of C. procera, bio-inoculants G. fasciculatum and T. viride caused greatest reduction in the multiplication of second stage juveniles of M. incognita in soil, number of root-galls and egg masses per root system. Consequently, the highest improvement in plant growth and total biomass of okra was observed in the same treatment. However, individual inoculation of C. procera and these bio-inoculants also showed significant improvement in growth parameters but was less as compared to concomitant inoculations. G. fasciculatum was found most efficacious against disease development caused by M. incognita followed by T. viride and C. procera. The agronomic parameters like NP and K contents were significantly enhanced in such plants which received combined inoculations of organic matter and bioinoculants. Soil application of organic matter also influenced the microbial activity of these bio-inoculants, more with the G. fasciculatum than T. viride. This investigation has further explained that inoculation of such bio-inoculants and organic matter may utilized successfully in field condition for ecofriendly management of plant-parasitic nematodes including M. incognita without altering existing harmony among beneficial micro-organisms.
