Description Pot culture experiment was conducted in the net house of the Department of Nematology, College of Agriculture, OUAT, Bhubaneswar to study “The effect of AM fungus (Glomus fasciculatum) and oilcakes against root knot nematode (Meloidogyne incognita) infecting brinjal”. The experiment comprised of 16 treatments in order of T1 (AM fungus @ 5g/m²), T2 ( AM fungus @10g/m²), T3 (Neem cake @ 100g/m²), T4 (Neem cake @ 200g/m²), T5 (Mustard cake @ 100g/m²), T6 (Mustard cake @ 200g/m²), T7 (Sesame cake @ 100g/m²), T8 (Sesame cake @ 200g/m²), T9 (T1 +T3), T10 (T2 +T4), T11 (T1 +T5), T12 (T2 + T6), T13 (T1 + T7), T14 (T2 +T8), T15 (Carbofuran as standard check @ 0.3g a.i./m²), T16 (Untreated Inoculated Check). Each treatment was replicated thrice following complete Randomised Design. Results indicated that all treatments significantly increased the plant growth parameters and reduced root knot nematode population and other infection parameters over check. Also treatments where AM fungus was inoculated, there was significant rise in the population of AM fungus, its colonization in roots as well as availability of phosphorus in soil over check and other treatments. However among various treatments, T12 where mustard cake @ 200g/m² + AM fungus @ 10g/m² and T11 where mustard cake @ 100g/m² + AM fungus @ 5g/m² were applied in pot soil, results of plant growth parameters, population growth of root knot nematode and AM fungus as well as other infection parameters were found statistically at par. Both the treatments performing better than others contributed significantly increase in shoot length by 34.83% & 29.44%, number of leaves by 65.46% and 55.11%, fresh shoot weight by 77.17% & 70.14%, dry shoot weight by 116.78% & 113.86%, root length by 73.51% & 62.38%, fresh root weight by 69.33% & 54.42%, dry root weight by 93.78% & 79.09%, availability of phosphorus in soil by 76.3% & 63%, and colonisation of AM fungus in roots by 72.47% & 58.39% respectively with corresponding decrease in order of number of root galls by 94.16% & 90.66%, number of egg masses by 91.33% & 79.51%, root knot index by 57.17% & 42.82% and root knot nematode population by 92.63% & 91.13% over check (T16). Though T11 & T12 exhibited better result as compared to other treatments and over check (T16) , yet in view of cost effective and low cost management option, application mustard cake @ 100g/m² + AM fungus @ 5g/m² in T11 is considered the most promising management option against root knot nematode (M. incognita) affecting brinjal crop.
