Abstract
Nodulation on clus terbean (Cyamopsis tetragonoloba L. Taub.) is usually poor leading to low productivity of this co mmercially important crop. Recently, A CC (1-aminocyclopropane-1-carbo xylate) utilizing rhizobacteria have been found to lower the level of nodulation inhibitor ethylene leading to improved nodulation and plant growth of legumes. In this study, Pseudomonas isolates obtained from the rh izosphere of clusterbean were screened for uti lizati on of A CC. On ly 38.9% Pseudomonas isolates showed growth on ACC supplemented plates. Inoculation of clusterbean with ACC + Bradyrhizobium isolate GSA11 or Rhizobium isolate GSA 6 formed 45 and 40 nodules, respectively at 60 days of growth under sterilized chillu m jar condit ions. The coinoculation of ACC + Pseudomonas isolate CPA123 with ACC + Bradyrhizobium isolate GSA11 caused 220.7% increase in plant dry weight in co mparison to control uninoculated plants at 60 days of gro wth. In co mparison to coinoculation with A CC - Pseudomonas isolate CPA 152, the co inoculation of Pseudomonas isolate CPA123 showed more enhancements in symbiotic parameters of clusterbean. Thus, ACC + rhizobacterial cultures could act as better inoculants for enhancing nodulation and plant growth of clusterbean under field conditions.
