Abstract:
Two groundnut cultivars treated with Rhizobium strain with two concentrations and isolated local
Mycorrhiza fungi chosen for this study compared with chemical fertilizers. The strains were
screened in pots at the College of Agricultural Studies, Sudan University of Science and
Technology.The study was performed to investigate the effects of Rhizobium strains and isolated
local Mycorrhizal fungi from sorghum rhizosphere on groundnut plant in terms of (plant height,
top dry weight, colour rating, nodulation, yield and tissue content of nitrogen, potassium and
phosphorus). The performance of the combination between Mycorrhiza fungi and Rhizobium
strain enhanced and developed the growth of groundnut plants. The performance of the
Mycorrhiza fungi alone enhanced the groundnut plant on nutrient uptake and plant and over the
inoculated plants and control. Rhizobium positively affected groundnut the plant growth traits
and nutrient uptake; The performance of urea fertilizer enhanced the plant weight of groundnut
M383 cultivar, also affected by the addition of Rhizobium bacteria as a single treatment and the
Mycorrhiza fungi in all measurements. The Ahmadi cultivar was also affected by the treatment
of Rhizobium bacteria in the yield, number and weight of root nodules. |
