Abstract
The impacts of biofertilizer (OBD) on cassava rhizosphere microbiome holistic soil function produced from anaerobic bio-digested from biowaste inoculated with beneficial microbes applied alone and in commination to cassava cultivation under rainfed conditions with inorganic fertilizer NPK (15:15:15) on an Ultisol soil Igbariam, Nigeria in 2012/2013 cropping seasons to determine the crop yield and growth components. Cassava stakes each measuring about 25cm was then planted at 1m x 1m spacing on top of the ridges. The treatments were arranged in a randomized complete block design replicated three times OBD-Biofertilizer in combination with NPK gave significantly higher cassava root yield (P < 0.05) than the control. Application of recommended dose of NPK fertilizers along with biofertilizer resulted in significantly higher growth attributes in addition to dry matter production and tuber yield. With application of biofertilizer to low marginal soils for cultivation of cassava, the macronutrients and micronutrients enhanced by biofertilizer microbial inoculants that transforms roots development, photosynthetic rate, replenished extracted soil nutrients by cassava harvest and improved nitrogen use efficiency. Biofertilizer can improve highly weathered and leached Oxisols, Ultisols and Alfisols soils where cassava is cultivated in the tropics and mitigate environment degradation. Biofertilizer applied cassava production soil provides interactions produces stability and resilience of soil with respect to functional characteristics. The trilogy papers illuminate the biofertilizer impacts on the functions of rhizosphere microbiome on cassava crop cultivation, development and protection (Graphical Abstract).
