Effects of Bradyrhizobium and Vesicular Arbuscular Mycorrhizal (VAM) inoculation on symbiotic pproperties, yield and seed quality of groundnut [Sudan]
1996
Mohamed Zein, E.M.
A local and introduced Bradyrhizobium strains and a locally-isolated VAM fungi were used to study their effects on groundnut in clay (Shambat) and sandy (El-Rwakeeb) soil in a pot experiment. A field experiment was carried out at El-Rwakeed to study the effect of urea, superphosphate and chicken manure on inoculated or uninoculated groundnut. Inoculation signifcantly increased number of nodules, dry weight of shoot, root and nodules, plant N and P content, number and dry wieght of pode, yield and seed composition and quality in both pot and field experiments. Introduced strain (TAL 1000) was more effective than locally-isolated strain (ENRRI 16). All fertilizers added to inoculated or uninoculated groundnut significantly increased all measured parameters. Chicken manure reflected good results than urea and superphosphate, which showed comparable results. All treatments significantly improved the seed compositon especially protein and oil content
