Abstract

SYMBIOTIC EFFECTIVENESS OF RHIZOBIUM LEGUMINOSARUM BV. VICIAE WITH PEA PLANTS AS INFLUENCED BY AZOTOBACTER CHROOCOCCUM

Highlights

Pre-sowing seed inoculation of legume crops with symbiotic bacteria, commonly known as rhizobia, is an important agricultural practice intended to increase nitrogen fixation and seed yields of these crops [Bushan 1998, Graham, Vance 2003, Deaker et al 2004]
Various strategies have been studied to improve efficacy of rhizobium inoculants applied to legumes grown on soils colonized with high natural populations of symbiotic bacteria and those include: selection of Journal of Ecological Engineering vol 16(4), 2015 rhizobial strains for increased N2 fixation capacity or higher competitive ability, in-furrow application of liquid inoculants or application of mixed inoculants of rhizobia with other plant growth promoting bacteria, like Azotobacter, Azospirillum and Pseudomonas [Burns et al 1981, Bashan 1998, Graham, Vance 2003, Deaker et al 2004]
The solid-state carrier – milled brown coal – used in this study was a suitable material for preparation of inoculants containing monoculture of R. leguminosarum bv. viciae (Rlv) or mixed culture of Rlv and A. chroococcum
