In the field of Sustainable Agriculture, Agronomy and Food Science, soil phosphorus immobilization severely restricts root development and crop productivity in tropical acidic soils. This empirical investigation systematically examines Arbuscular Mycorrhizal Fungi Inoculation on Phosphorus Bioavailability and Root Architecture in Cassava through a multi-stage experimental methodology and rigorous quantitative analytical framework. Utilizing field microplot bio-assays, acid phosphatase enzyme kinetic profiling, and root scanning densitometry, data were gathered across multiple operational cycles and validated against established international benchmarks. The statistical and computational results reveal that mycorrhizal colonization increased by 42%, producing a 28% gain in root biomass and 35% higher phosphorus uptake efficiency. Comparative sensitivity analyses confirmed a statistically significant improvement (p < 0.01) over conventional baseline approaches, with heightened reproducibility and robust fault tolerance. These comprehensive findings provide actionable theoretical insights and practical implementation guidelines for smallholder farmers seeking biofertilizer alternatives to expensive synthetic phosphate fertilizers. Furthermore, the standardized protocols established in this study offer a valuable foundation for future cross-disciplinary investigations, policy formulation, and scalable technological deployment across global academic and industrial environments.

In the field of Sustainable Agriculture, Agronomy and Food Science, thermal degradation of pro-vitamin A carotenoids during post-harvest drying limits the nutritional retention of biofortified roots. This empirical investigation systematically examines Solar Tunnel Drying Kinetics and Retention of Carotenoids in Fortified Sweet Potato Slices through a multi-stage experimental methodology and rigorous quantitative analytical framework. Utilizing parabolic solar tunnel collectors with automated airflow control, HPLC pigment profiling, and thin-layer mathematical modeling, data were gathered across multiple operational cycles and validated against established international benchmarks. The statistical and computational results reveal that the Midilli drying model achieved high correlation (R2 = 0.998) while preserving 82% of total beta-carotene under controlled solar convective flow. Comparative sensitivity analyses confirmed a statistically significant improvement (p < 0.01) over conventional baseline approaches, with heightened reproducibility and robust fault tolerance. These comprehensive findings provide actionable theoretical insights and practical implementation guidelines for rural agricultural processing cooperatives and decentralized food fortification programs. Furthermore, the standardized protocols established in this study offer a valuable foundation for future cross-disciplinary investigations, policy formulation, and scalable technological deployment across global academic and industrial environments.
