AbstractThe present study was aimed to evaluate the pathogenicity of Meloidogyne incognita at different levels of inoculation (10, 100, 500, 1000, 5000 and 10000 J2/plant) on okra cv. Pusa Green Gold. The maximum plant growth, reaching 51.06 cm height was observed with 10 J2/plant, while the shortest plants were recorded in the group inoculated with 10000 J2/plant, measuring 23.23 cm. Highest number of galls per plant was observed in 10,000 J2 inoculated okra plants. The study revealed 1000 infective juveniles per kg soil exhibited pathogenicity, and caused significant suppression in the plant growth of okra cv. Pusa Green Gold.
