A replicated pot culture experiment was conducted to study the comparative efficacy of different oil cakes on management of root knot nematode (Meloidogyne incognita) infecting tomato. The results revealed that barring the untreated check, all other treatments significantly increased the plant growth parameters, total chlorophyll content and reduced root knot nematode population as well as number of galls. Among various treatments, T8 where neem cake @ 100g/m² and T7 where mahua cake 100g/m² were applied in pot soil, resulted plant growth parameters, total chlorophyll content and population growth of root knot nematode were found statistically at par. Both the aforesaid T8 and T7 treatments performing better than others contributed significantly as percentage of increase in plant height by 85.91% and 73.84%, fresh shoot weight by 60.66% and 55.85%, root length by 89.50% and 78.43%, fresh root weight by 87.04% and 78.98%, total chlorophyll content by 83.09% and 72.88% with corresponding decrease in order of number of root galls by 78.91% and 68.06% over untreated inoculated check (T10). Though T7 and T8 exhibited better results as compared to other treatments and over check (T10), yet in view of easy availability and low management option, application of neem oil cake @ 100g/m2 in T8 is considered the most promising management option against root knot nematode (Meloidogyne incognita) infecting tomato.
