Abstract: Cassava (Manihot Esculenta Crantz) demand by 700 million people and cultivated in 105 countries between Tropic of Cancer and Tropic of Capricorn within 2300m elevations globally for food security and the cultivation impact on biodiversity require biofertilizer to mitigate climate challenges, crop sustainable development and regenerative agriculture. Nigeria is the world largest producer with a global average yield of 11.80 t/ha, cassava yields can reach 80 t/ha, compared to the current world average yield of just 12.8 t/ha. Biofertilizer solves the traceability problem of chemical farm inputs, suitability and nutrient use efficiency as an integral function of the rhizosphere microbiome via plant microbe interactions for improved soil health quality and crop degradation management. Cassava cultivation with biofertilizer will reduce hydrogen cyanide (HCN) levels in the crop as an integral bioavailability of soil organic matter and nutrient use efficiency. Plant growth-promoting rhizobacteria (PGPR) in the biofertilizer will ameliorate plant abiotic stress and bio-control diseases management. Easily accessed agrobacterium inoculant in biofertilizer has potential for transgenic cassava cultivar development for improved yield and nutrient biofortification. This book chapter encapsulate the case studies trilogy research article papers on biofertilizer impacts on soil microbiome during cassava cultivation for crop yield, soil health, regenerative agriculture, value chain development, food and nutrition security.

Biofertilizer Impacts on Soybean [Glycine max (L.)] Cultivation, Humid Tropics : Biological Nitrogen Fixation, Yield, Soil Health and Smart Agriculture Framework (Published)

Biological nitrogen fixation (BNF) soybean cultivar TGx 1440 -1E cultivation for grain yields and soil microbiome with different soil amendments in humid tropics in the late cropping season of 2010, Abeokuta, Nigeria, at Latitude 70 121 N and Longitude 30 251 E in randomized complete block design (RCBD) replicated three times. Treatments application includes: agro-waste recycled to biofertilizer in anaerobic biodigester with two biofertilizer formulations (GF1 and GF2), sunshine fertilizer (SF) and chemical fertilizer (NPK 20:10:10).  Soybean vegetative growth parameters, nodulation, amount of nitrogen fixed, yield and yield components were determined at 8 weeks after planting (WAP). GF2 had significantly (P < 0.05) higher number of leaves. GF1 had significantly (P < 0.05) higher number of pods and seed weight/plant with lower biological nitrogen fixation, compared to other treatments. Soybean cultivars breeders should integrate biofertilizer into seed development programme, that bypass the naturalized soil rhizobia and nodulate only with highly effective inoculant strains under environmental stress, improved  soil resilience for climate mitigation with rhizosphere-microbial interactions to manage soybean cyst nematode (SCN). Smart agriculture framework developed impacts on trans-disciplinary approach, soyabean cultivation nitrogen use efficiency (NUE), remote access to agriculture data in real-time, crop development, supply chain management, proftability and biofertilizer varietal characteristics.
