A pot culture experiment was conducted during Kharif season in the year 2021- 2022 at Green polyhouse, Department of Nematology, College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha in order to study effect of different inoculum level of M. incognita on chlorophyll content of pigeon pea. The experiment was laid out in Completely randomized design (CRD) with 5 treatments i.e T1 (500 J2/plant), T2(1000J2 / Plant), T3(1500J2/plant), T4(2000J2/plant), T5(Control)and 4 varieties were UPAS-120(R), IPA-15-1 (MR), IPA 14-7(S), CO-6(HS). To find out the effect of increase in inoculum level of nematode on chlorophyll content of pigeon pea leaves showed that highest reduction in chlorophyll in treatment T4 then T3, T2 and then T1 over control T5. The results have demonstrated that nematode infestation leads to highest decreased by 41.75% total chlorophyll content (a+b) in UPAS -120(R)) in the leaves and highest decrease found in case of high inoculum level inoculation of nematodes in the pigeon pea plant.
