Pathogenicity of Meloidogyne javanica to chickpea (Cicer arietlnum) in relation to soil types, Rhizobium treatment, size of pots and time interval*
Abstract
An experiment was carried out to see the pathogenicity of Meloidogyne javanica in relation to soil types, size of pots and time interval in taking various observations on growth parameters in chickpea. It was found that initial inoculum of 10,000 larvae/plant in smaller pots (15 cm) after two months of inoculation and 1000 and 10,000 larvae/plant in large pots (25 cm) after five months of inoculation proved to be pathogenic in all the three type of soils. Although, plant growth characters were better in sandy loam soil but pathogenic level remained the same in all types of soil. Similarly, Rhizobium treated seeds showed better growth characters than untreated seeds but there was no difference in pathogenic level in both the treatment (treated and untreated). However, fresh root weight was more in plants where treatment was done with Rhizobium culture.
