No full textManual cono weeding in rice cultivation demands significant labor and energy. To address the same, a power-operated cono weeder was developed at the Agricultural Engineering and Research Institute, Tamil Nadu Agricultural University, Kumulur, Trichy, between 2018 and 2020. The new design incorporated a main frame, a 1 kW petrol engine, a power transmission system, a handle, plastic molded ground wheels, a slider crank mechanism for weeding cone motion, an adjustable depth control lever, and plastic molded weeding cones with MS blades. It offers adjustable depth settings from 15 mm to 70 mm. Field performance was assessed across three operational speeds (0.28 m s-1, 0.42 m s-1 and 0.56 m s-1) and water levels (10 mm, 25 mm, and 40 mm). Results showed maximum weeding efficiency (85%) and field capacity (0.026 ha h-1) at an operational speed of 0.42 m s-1 and a water level of 25 mm. Minimal plant damage (1.2%) occurred at an operational speed of 0.28 m s-1 and a water level of 10 mm. The weeder demonstrated an operational efficiency of 86.5% in the field. This power-operated cono weeder offers a promising solution to the labor-intensive manual cono weeding in rice cultivation. Its adjustable depth control and efficient field performance indicate potential for enhancing productivity while reducing labor costs and environmental impact
Integration of Digital Innovation in Urban Farming: A Review towards Advancing Sustainable Food Security in South and Southeast Asian Cities
No full textFactors like population growth, climate change, rural-urban migration and depletion of limited resources have significantly intensified demands placed on the food chain supply. Recently, urban farming has been receiving attention due to its potential to make a notable contribution to sustainable food production systems. To address the research gaps such as technology adoption factors, high cost, environmental benefits, geospatial data integration and policy framework etc., a systematic review of urban farming systems in the South and Southeast Asian countries was performed. Review was conducted using screening and exclusion-inclusion criteria based on the ‘preferred reporting items for systematic reviews and meta-analysis’ (PRISMA) method. The databases were taken from Scopus and Web of Science considering keywords such as ‘urban farming’, ‘vertical farming’, ‘food security’, ‘urban sustainability’, as well as various combinations thereof, focusing on the Southeast and South Asian countries. The review revealed that sustainability is a multi-dimensional factor in the context of urban farming, as it decreases the negative effects on environment and foster its long-term sustainability. Urban farming may help development of more sustainable food systems by increasing the efficiency of smart water usage and managing trash properly. The adoption of energy-efficient technologies powered by sustainable energy resources can play a crucial role in decreasing the carbon emissions associated with the operations of urban farming as well as urban self-sufficient food systems. Urban farming automation can facilitate the optimization of land exploitation and generation of increased yields per unit of land. Urban farming with the fusion of technological advancements have the ability to establish more self-reliant and ecologically conscious systems for producing food, thereby guaranteeing the welfare and food security of urban populations. This article will help innovative researchers, farmers and policy makers in advancing urban farming in an integrated and advancing manner toward sustainable food security
