Impact of Pseudomonas aeruginosa MAJ PIA03 affecting the growth and phytonutrient production of castor, a primary host-plant of Samia ricini

Castor (Ricinus communis L.) is a primary food plant of eri silkworm, Samia ricini Donovan endemic to Northeast India. Plant growth promoting rhizobacteria (PGPR) plays crucial role in growth and productivity of agricultural crops. Eighty-five Pseudomonas strains were isolated from thirty rhizospher...
