Response of Guar ( Cyamopsis teteragonolopa L.) to Bradyrhizobium Inoculations in Semi-arid Environment

Bio-fertilizers are environment friendly and protect the environment against the pollutant. Afield experiment was conducted in semi-arid environment ”North Kordofan of Sudan” in rainy seasons (2008/09) to investigate the effect of inoculation of Bradyrhizobium on growth and yield of guar (Cyamopsis teteragonolopa L.) in gardoud soil. The treatments used were: un-inoculated control, inoculated with TAL169 and Hi12 (introduced), and other12 strains (Local Isolated Strains). The experiment was arranged in a randomized complete block design with three replications. Estimated Parameters were: fresh and dry weight of shoot and root, plant height, number of fruiting branches, number of nodules, number of pods per plant, 100-seed (g) and total seed yield (ton/ha). The results showed that, the Bradyrhizobium significant increased growth and yield attributes of guar.
