A field experiment was conducted at Dongola University Farm at Al-Seleim to study the effects of Rhizobium leguminosarum biovar viceae and Bacillus megatherium var. Phosphaticum (BMP) inoculation and phosphorus and nitrogen fertilization on the symbiotic properties, and yield of faba bean (Vicia faba L.) cultivar seleim. Rhizobium inoculation significantly (P≤0.05) increased nodulation, shoot and nodule dry weight, nitrogen and phosphorus content in shoot and yield. BMP inoculation significantly (P≤0.05) increased nodulation, nodule, shoot and root dry weights, nitrogen and phosphorus content in shoot Rhizobium and BMP co-inoculation significantly (P≤0.05) increased nodulation, nodules, shoot and root dry weights, nitrogen and phosphorus content and yield. Application of chemical fertilizers increased shoot and root dry weight, nitrogen and phosphorus content and yield. The 4-way interaction significantly (P≤0.05) increased shoot dry weight and phosphorus content. © 2010, American-Eurasian Network for Scientific Information. Source

A field experiment was conducted at Dongola University Farm at Al-Seleim - Dongola University Farm, Northern State to study the effects of Rhizobium Ieguminosarum biovar viceae and Bacillus megatherium var. Phosphaticum (BMP) inoculation and phosphorus and nitrogen fertilization on the yield and seed quality of faba bean (Vicia faba L.) cultivar seleim. Rhizobium inoculation significantly (p≤0.05) increased yield, seed ash, fat, crude protein and 100-seed weight. BMP inoculation significantly (p≤0.05) increased seed moisture, fat, crude fiber and crude protein content. On the other hand, Rhizobium and BMP Co-inoculation significantly (p≤0.05) increased yield, seed ash, protein content and 100-seed weight. Application of chemical fertilizers increased yield, seed ash, fat, crude protein content and 100-seed weight. In addition to that, nitrogen fertilization significantly (p≤0.05) increased the hydration coefficient. Nitrogen fertilization in the presence of Rhizobium significantly (p≤0.05) increased the cookability. © Asian Network for Scientific Information, 2010. Source

A field experiment was conducted at Elbagair area, central Sudan, for two successive seasons 2009/2010 - 2010/2011 to study the effects inoculation with five introduced or locally isolated Rhizobium or Bradyrhizobium strains each alone or with Bacillus megatherium var. phosphaticum strain (BMP) alone, and combination of each rhizobial strain with Bacillus megatherium var. phosphaticum strain (BMP) on the symbiotic properties, and yield of pigeon pea (Cajanus cajan). Rhizobium and BMP inoculation separately significantly (P≤0.05) increased nodulation, nodules dry weight, root dry weight, shoot dry weight, nitrogen and phosphorus content in shoot and seed yield of pigeon pea plants in comparison to the un-inoculated control. Rhizobium and BMP co-inoculation significantly (P≤0.05) increased nodulation, nodules, root and shoot dry weights nitrogen and phosphorus content in shoot and seed yield. The results of this study revealed the need for biological fertilizers with compatible effective strains for application to inoculate pigeon pea, especially this crop is cultivated in Sudan without fertilization.

A field experiment was carried out in season 2007/08 in two sites in a semi-arid zone in the Northern State of Sudan to study the effects of Rhizobium inoculation and urea fertilization on the symbiotic properties and yield of faba bean cultivar seleim (SM-L). Rhizobium inoculation individually significantly (P≤0.05) increased shoot and nodule dry weight, nitrogen content in shoot and yield. Inoculation with Rhizobium with addition of urea as starter dose (20 kg N/ha) increased number of nodules, shoot and root dry weights, nitrogen content and yield. Urea fertilization significantly (P≤0.05) increased shoot dry weight, number of pods and yield. The results of the study indicated the efficiency of using biofertilizer based on Rhizobium isolate ENRRI 9 in increasing the yield of faba bean in the studied sites in a semi-desert zone in Sudan.

A field experiment was conducted at Ummdagarsi area in Gezira state, central Sudan to study the effects of inoculation with Rhizobium and Bacillus megatherium var. Phosphaticum (BMP) and phosphorus and nitrogen fertilization on yield and seed quality of chick pea plants variety Bergag. Inoculation with root nodule bacteria significantly (P≤0.05) increased nodule number, shoot dry weight, root dry weight, nodule dry weight, shoot nitrogen content and chick pea seed yield. Inoculation with phosphate solubilizing bacteria was found to cause a significant (P≤0.05) increase in nodule number, dry weight of shoot, root and nodule, shoot nitrogen and phosphorus content and yield. Results revealed that the use of chemical fertilizers significantly (P≤0.05) increased shoot dry weight, root dry weight, nodule dry weight, shoot nitrogen and phosphorus content and yield. Source
