A field experiment was carried out during the rabi season of 2019-20 in the Instructional-cum-Research Farm, Assam Agricultural University, Jorhat for the management of M. incognita on Pumpkin. Pumpkin cultivar Karbi-I, was selected for the present investigation. The experiment was conducted in randomized block design with five treatments like T1- Trichoderma harzianum @ 20 kg/ha at time of sowing, T2- Mustard cake @ 750 kg/ha applied 15 days prior to sowing, T3- Trichoderma harzianum @ 10 kg/ha at time of sowing + Mustard cake @ 375 kg/ha applied 15 days prior to sowing, T4- Carbofuran @ 1 kg ai/ ha and T5- Control. Area of the experimental plot was divided in to 20 plots measuring 6 m x 3 m (18 m2) in each plot with four rows. The results of the field studies revealed that all the treatments were found to be effective in increasing the overall plant growth, number of fruits per plot and yield per plot of pumpkin over control. Carbofuran @ 1 kg ai/ha gave the best result in respect of yield (155.12 q/ha) as well as reducing the nematode infestation (59.67 i.e number of galls and 46.70 i.e. number of galls). Combined application of Mustard cake and Trichoderma harzianum at applied doses brought about a significant reduction in number of galls (63.333), egg masses (56.42) and final nematode population (235.05 per 200cc of soil) in soil with increased yield (140.07 q/ha) compared to control. Among the bio treatments for management of M. incognita under field condition, combined treatments Trichoderma harzianum and Mustard cake was found to be the best so far as yield of pumpkin and reduction of nematode population is concern.
