Abstract
The effects of inoculation with single or dual cultures of nitrogen fixers on biomass accumulation, mineral nutrition, and activities of nitrogenase and dehydrogenase in cotton plants was studied. The results showed that inoculation with each of the four species Azotobacter sp., Azospirillum brasilense NO40, Bacillus polymyxa CF, and Rhizobium sp. separately significantly enhanced the N uptake, nitrogenase and dehydrogenase activities, and the total chlorophyll and phosphorus content. High nitrogenase and dehydrogenase activities of rhizosphere were obtained with Azotobacter sp. All the four species significantly increased the plant dry weight of cotton. C 2H 2 reduction and dehydrogenase activities of rhizosphere were significantly higher when dual inocula of Azotobacter combined with Rhizobium or As. brasilense NO40 were used than that of Azotobacter culture alone. Meanwhile, the significantly positive effects of inoculation with dual cultures on lint yield and N uptake were also observed.
