RESPONSE OF LENTIL CVS TO MELOIDOGYNE JAVANICA IN THE PRESENCE AND ABSENCE OF RHIZOBIUM IN THREE SOIL TYPES

Abstract

The response of lentil cvs Desi Masoor, K-75 and Malika Masoor to Meloidogyne javanica was studied in the presence and absence of Rhizobium sp. in three soil types. Plant growth of all the cultivars was best when grown in a mixture of 3:l clay:sand, followed by 2:2 and 1:3 c1ay:sand. However, susceptibility of the cvs to M. javanica increased in 1:3 c1ay:sand mixture and decreased in 3:l c1ay:sand mixture. The presence of Rhizobium had an adverse effect on nematode multiplication and galling in all the soil types. Soil type had no effect on nematode morphometric while the presence of Rhizobium and each of the cultivars affected all morphometrics parameters except stylet length and stylet knob width. Cv Desi Masoor was rated highly susceptible to M. javanica, K-75 as susceptible and Malika Masoor as tolerant.
