Biological Nitrogen Fixation and Productivity of Soybean in Maize - Soybean Intercrop Under Tillage and Bradyrhizobium Inoculation on Alfisols of Northern Guinea Savanna, Nigeria
A field study was conducted in the 2011 cropping season to investigate the effect of tillage and bradyrhizobium inoculation of soybean on biological nitrogen fixa- tion (BNF) and yield components in maize-soybean intercropping systems. Treat- ments comprised of two tillage practices (conventional tillage (CT) and reduced tillage (RT)) as the main plot and bradyrhizobium inoculation at four levels ...
