RHIZOBIAL POPULATIONS IN COASTAL SALINE SOILS OF BANGLADESH AND THEIR EFFECT ON LEGUME CROPS (Pages : 22 - 26)

M.S.I. KHAN, ZAHED U.M. KHAN, D. KHANAM AND M.I. UDDIN

The experiment was conducted in three coastal saline Upazillas viz. Kalapara Upazilla of Patuakhali district, Amtali and Borguna Sadar Upazilla of Borguna district along with a non saline Upazilla, Babuganj of Barisal district of Bangladesh during 2006-2007 to quantify the Rhizobium population in saline soils and their effect on legume crop production. Rhizobial populations, nodulation and yield of legume crops were reduced due to toxic effect of salt present in coastal soil. In saline locations the highest heterotrophic bacteria (14.0 x 106) including Rhizobium (4.26 x 106) were counted during March, the flowering period of the legume crops. Bacterial populations in saline soils were much lower than non-saline soil (8.86 x 106 and 38.60 x 106, respectively). Salinity stress adversely affected on plant growth, nodulation, biomass and seed yield. Nodule production by the legumes was almost half in saline soil than in non-saline soil. Biomass and seed yield in saline locations reduced 28% and 34%, respectively over non-saline location.Download
