Project Abstract

This study presents an integrated approach to advancing sustainable smallholder agriculture through a synergistic framework combining IoT-based climate control, hydroponic design, post-harvest preservation, precision irrigation, biostimulants, solar-powered cold storage, waste-to-energy, plant tissue culture, animal feed optimization, grain drying, genetic diversity for drought tolerance, biodegradable mulches, biological pest management, post-harvest robotics, fungal enzyme production, agroforestry, valorization of agro-industrial by-products, rainwater harvesting optimization, and aquaponics. The core objective is to develop and validate a modular, data-driven platform that enhances productivity, reduces losses, and lowers input footprints across diverse farming systems. The integrated greenhouse subsystem employs an array of environmental sensors (temperature, humidity, CO2, light intensity, soil moisture) connected to IoT gateways and a cloud analytics engine that leverages machine learning to optimize climate control, irrigation schedules, and energy use, thereby improving crop uniformity and resource efficiency. Parallel development of a small-scale hydroponic unit targets urban food production, with nutrient solution dynamics and aeration control tuned via real-time data streams to maximize yield per unit area while minimizing water and nutrient inputs. Post-harvest treatments using natural preservatives are evaluated for efficacy against microbial spoilage and sensory quality degradation, informing protocol recommendations for different fruit categories. The precision irrigation system integrates soil moisture readings and local weather forecasts to deliver accurate irrigation, reducing over- and under-watering and conserving groundwater resources. Biostimulants are assessed for their ability to enhance germination rates, seedling vigor, and stress resilience in climate-robust cultivars, with responses quantified through vigor indices and early growth metrics. In addition, the project explores a solar-powered cold storage solution enabling year-round post-harvest handling in rural greenhouses, complemented by waste-to-energy pathways converting agricultural residues into biogas to offset energy costs and feed users on-site. A microtiller-based tissue culture protocol accelerates propagation of high-value crops, supported by aseptic techniques and genotype-specific media optimization. Feed formulation research focuses on digestibility and nutrient balancing for sustainable livestock production, while CFD-driven simulations optimize a compact grain dryer to minimize drying losses and energy consumption. Genetic diversity assessment and marker-assisted selection for drought-tolerant rice varieties are conducted to identify robust genotypes for future deployment, and biodegradable mulch films derived from agricultural waste are evaluated for soil moisture retention and biodegradability. The pest management component tests biological control agents within an IPM framework for tomato cultivation, and post-harvest robotics enable automated sorting and packaging to improve handling efficiency. A fungal bioreactor explores enzyme production from agricultural by-products to valorize waste streams, while agroforestry designs promote soil health and biodiversity. Sensory and nutritional analyses of alternative protein sources from agro-industrial by-products inform upcycling strategies. Modeling and optimization of rainwater harvesting informs irrigation scheduling, and the valorization of cow dung and crop residues into organic amendments closes nutrient loops. Finally, a low-cost aquaponics system demonstrates integrated fish and vegetable production. The project employs a mixed-methods evaluation, including field trials, statistical analysis, life-cycle assessment, and user-centered usability studies to ensure scalability, adaptability, and economic viability across diverse contexts.
