Bacterial diversity of wheat–maize–legume cropping system

Seema Rawat, Asifa Mushtaq

Abstract :

 Thecropping systems are of central interest to explore for sustainable agriculture.This study focused on  the characterization of rhizobacteria of wheat–maize–legume cropping system. In the field chosen for the  present study, maize–legume intercropping is done.The wheat rhizobacterial population (log10cfu) varied from 6.48  to 9.57.Bacillus was documented to be dominant population of zero day (40%) whilePseudomonas was the dominant  population (33%) on 30th day of cropping. On 60th day of cropping Pseudomonas became a predominant population  (50%) while on 90th day of cropping Pseudomonas and Corynebacterium were the dominant population (30%).The  maize rhizobacterial population (log10cfu) varied from 5.4 to 9.5.Alcaligeneswas documented to be dominant population of zero day (40%). Klebsiella was the dominnatrhizobacteria on 30th day (40%) while Pseudomonas and Alcaligenes were equally dominant on 60th day (30%). Pseudomonas was dominant on 90th day (60%) as well as 120th  day (47%). The rhizobacterial population (log10cfu) of legume varied significantly from 5.44 to 7.36.The rhizobacterial  population was found to vary in species richness from 0d to 90d of cropping. Bacillus was documented to be dominant population of zero day (40%) while Pseudomonas was the dominant population (33%) on 30th day of cropping.  On 60th day of cropping Pseudomonas became a predominant population (50%) while on 90th day of cropping Pseudomonas and Corynebacterium were the dominant population (30%). These isolates exhibit a significant plant growth  promotion attributes viz., siderophore production, phosphorus solubilization, protease and rhamnolipid production.
