VARIETAL INTERACTION IN REDGRAM-RHIZOBIUM SYMBIOTIC ACTIVITIES IN THE ACID LATERITIC SOILS OF VAMBAN

Abstract

Poor nitrogen content due to soil reaction is one of the problem: in Vamban soil series. Different rhizobial strains were screened fo: their performance with different cultivars of redgram. Rhizobial see bacterization enhances the nodulation, plant biomass and grain yiel in different cultivars of redgram under acid lateritic soil of Vamban. Among the cultivars, maximum grouth, nodulation and yield attributes were recorded with T 21 followed by CO 5 and A 3-1. Due to inoculation with rhizobia redgram seed yield was increased from 16.66 to 58.335 over uninoculated control.

Keywords: Symbiosis, Acid lateritic Soil, Redgran-Rhizobium.
