Effect of Rhizobium Innoculation on Growth, Nodulation Count and Yield of Soybeans Glycine Max Grown in Biochar Amended Soil of Sounthern Guinea Savana of Nigeria

Replenishment of depleted soil nitrogen depends largely on addition of inorganic fertilizers but due to problems of scarcity and high the cost of these fertilizer. Rhizobia inoculation is a cheaper, easier and safer option to improve soilnitrogen fixation and increase productivity of grain legumes.The experiments were conducted during 2016 and2017 rainy season with the aimed of evaluating the potentials of rhizobium inoculation on growth, nodulation count and yield of soybean planted in biochar amended soil. The results showed that Rhizobium inoculation of soybeans and biochar soil amendment didnot showed any significant increase on allgrowth parameter at 8 weeks after planting in 2016 and 2017 cropping seasons. However, inoculated soybeans produced significantly higher number of 25.35 and 23.42 roots nodules per plant compare to the control. Rhizobium inoculation and biochar soil amendment had a significant increase on all the yield parameter assessed in both years of cropping. All the soybeans that were inoculated with rhizobium produced the highest number of flowers 58.45 and 56.84 highest number of pods per plant 48.15 and 35.34 and highest seed weight of 2.67 and 2.85 t ha .1 Application of 10 t ha 1 of biocharproduced the highest number of flowers 63.26 and 68.21 highest number of pods per plant 53.45 and 54.25 and highest seed weight of 2.53 and 2.69 t ha 1 in 2016 and 2017 cropping seasons respectively.
