Effect of different levels of inocula of Meloidogyne incognita on plant growth of Pea (Pisum sativum L.) and reproduction of nematodes

Abstract

An experiment was carried out to study the effect of Meloidogyne incognitaon growth of Pisum sativum (Cv. Kashi Nandini) under glass house conditions by inoculating different inoculums levels i.e. 0 (control), 10, 100, 1000, 10,000 second stage juveniles (J2) of M. incognita along with supernatant. The results revealed that the increase in inoculum level of M. incognita, there was a progressive decrease in growth parameters of the crop as the levels of inocula increased. Significant reduction in plant height, root length and fresh and dry weights of roots and shoots were declined. Maximum galls, egg masses and eggs per egg mass were recorded more pronounced and significant reduction was observed at higher inoculum levels i.e. 1000 and 10,000 J2/pot.
