Abstract
A pot experiment was conducted to evaluate the efficacy of different oil cakes against the
root knot nematode. Root knot nematodes are the major agricultural pest of wide range of crops
worldwide. Chickpea, Cicer arietinum L., family Fabaceae, is a high yielding proteinaceous pulse crop
with India being the leading producer. Root knot nematodes are one of the major biological constraint that
reduces per capita yield of this pulse crops. In the present investigation, studies were made to determine
the efficacy of different oil cakes viz. Azadirachta indica (Neem), Brassica campestris (Mustard) and
Gossypium hirsutum (Cotton). Two doses (50 and 100 g) of each neem, mustard and cotton oil cakes
were applied to reduce nematode infestation in chickpea. Results revealed that root gall development due
to Meloidogyne incognita were significantly reduced in all the treatments and enhance all the plant
growth characters of C.arietinum. Higher dose of neem oil cake was found to be most effective as
compared to other treatments. Hence, it may be concluded that oil cakes are better substitute against
nematicide for the effective control of root-knot nematode and reduce environmental hazards for
ecologically safe environment.
