Abstract

Root-gall nematode disease of okra as affected by Jatropha curcas and the consequent pod proximate composition were studied. This was on sandy loam soil endemic in Meloidogyne incognita. A 2x4 factorial experiment in randomized complete block design with four replications was used. Ground J. curcas seeds and leaves were separately applied at 0,20, 40 and 60g/plant. Results showed that okra root-galls decreased as application rate of J. curcas increased. Percentage carbohydrate, protein, fibre and moisture contents however correlated negatively with root-gall responses. The reverse was however true for crude fat content.

Keywords: Jatropha curcas,, nematode, okra, proximate composition and root-gall
