PATHOGENICITY OF MELOIDOGYNE INCOGNITA ON CORCHORUS OLITORIUS

O. S. Balogun, O. Babatola

Abstract


Two experiments were carried out to study the pathogenic effects of Meloidogyne incognita on two cultivars of Corchorus olitorius. Plant height, mean number of leaves per plant, mean leaf area, fresh and dry shoot weight and chlorophyll content decreased with increases in initial inoculum levels far both cultivars in the two experiments. N.P.K. 15:15:15 was found to improve the tolerance of the plants infected by M. incognita by markedly reducing the yield losses compared with plants which received no fertilizer treatment, even at lower inoculum levels.
