Assessment and Prediction of Whole Body Vibration Exposure in Agricultural Tractors During Tillage Operations Using Supervised Machine Learning
No full textRide comfort during field operation is required for the operator’s health and safety. The extended exposure to whole body vibration (WBV) can adversely impact operator health, causing fatigue, spinal injuries, and long-term musculoskeletal disorders. This study focuses on analyzing and predicting tractor ride comfort using supervised machine learning techniques. Ride comfort was evaluated using metrics such as Overall Vibration Value (OVV), A(8), and Seat Effective Amplitude Transmissibility (SEAT, %). Experimental data were collected from three different tractor models operating under different tillage operations. Variables such as engine power, engine speed, working depth, implement type, and the operator’s body mass were considered to understand their influence on vibration levels. The results revealed that the OVV and A(8) values exceeded the exposure values of ISO 2631-1:1997. These higher levels indicate a risk to operator health during prolonged tractor use. Supervised machine learning models, including Least Absolute Shrinkage and Selection Operator (LASSO) Regression, Support Vector Regression (SVR), Extreme Gradient Boosting (XGBoost) Regression, and Artificial Neural Networks (ANN), were developed to predict OVV values using the identified input features. The effectiveness of each model was assessed using evaluation metrics like Mean Absolute Error (MAE) and the coefficient of determination (R²). The results showed progressive improvement in predictive accuracy, with R² scores of 0.62 for LASSO, 0.74 for SVM, 0.82 for XGBoost, and 0.92 for ANN. The ANN model outperformed with the higher R2 value and lower Mean Square Error (MSE) value of 0.16
Optimization of Operating Parameters for the Performance of Remote Controlled Two-Row Root-washed Type Paddy Transplanter
No full textTransplanting of paddy remains a labour-intensive operation, involving significant human effort and high input costs. The performance of a paddy transplanter is also affected by the age of seedlings and the status of sedimentation after puddling. This study was undertaken to optimize two parameters, namely, seedling age and sedimentation period after puddling in order to maximize the output from a remote-controlled, root-wash-type paddy transplanter. The seedling age was varied from 15 to 30 days, and the sedimentation period from 8 to 48 h after puddling. Planting efficiency, effective field capacity and field efficiency were considered as dependent parameters. Using Response Surface Methodology (RSM), a statistical tool, a total of 13 experiments were conducted in a systematic manner. The measured dependent parameters were recorded and analyzed. It was found that both seedling age and sedimentation period significantly influenced planting efficiency. The study concluded that the maximum planting efficiency of 94.8%, with an effective field capacity of 0.059 ha h-1 and a field efficiency of 65.51%, could be achieved at a seedling age of 24 days and a sedimentation period of 30 h. Results of this study will guide in selecting the seedling age and sedimentation period to achieve maximum output from the remote-controlled, root-wash-type paddy transplanter
Rural Economy - Critical for Mechanization
No full textAgricultural mechanization is broadly defined as the process of utilizing engineering and technological innovations such as farm tools, machinery, equipment, and power sources to perform agricultural operations more efficiently and effectively. According to the Food and Agriculture Organization (FAO), mechanization encompasses not only the use of tractors and harvesters but also implements for land preparation, irrigation, sowing, weeding, harvesting, processing, and storage. It is an essential component of agricultural modernization, enabling farmers to enhance productivity, reduce drudgery, save time, and ensure timeliness in crop operations
Reimagining Rice Milling: India’s Shift to Smart, Sustainable Solutions
No full textRice has been one of the staple meals of people worldwide for thousands of years. Even today, one of the key players of the agricultural industry is the cultivation of rice. And one of the key players in global rice cultivation is India. Within the last few decades, India has evolved into one of the largest players in the global rice market. The areas around the Indo-Gangetic plains, the Eastern and Western Ghats, and the Brahmaputra Valley have the perfect climate, soil, and rainfall needed for rice cultivation. As such, rice and India have become inextricably intertwined with each other in the global market. However, the traditional rice milling practices are now facing limitations in this ever-evolving world. The increasing costs of the raw materials, the outdated technology, improper disposal of waste, financial problems: these are only some of the issues plaguing the development of rice production in India. These issues, and more, are resulting in an increasing need for transformation, which will better the efficiency, traceability, and sustainability of these practices
Solarizing Indian Agriculture – How Banks are Driving Adoption of Solar Energy
No full textSustainable farming is gradually making deep inroads into Indian agriculture with more energy conservation centric practices. Rising fuel costs and irregular electricity supply hampers farm productivity and income stability. As such access to reliable energy has become a critical factor for the farmers. In this context, solar energy has emerged as a transformative solution for the agriculture sector. However, the large-scale adoption of solar energy in farming requires more than technology, it needs regular financing support with seamless integration with government policy measures. This is where; Banks play a pivotal role as enablers and catalysts of solar energy adoption among the farming fraternity. Energy is an indispensable input across the Agri Value Chain, especially for supporting critical activities like irrigation, handling of post-harvest, storage, and processing. Traditionally, farmers have depended on diesel pump sets or irregular electricity supply, leading to higher operating costs and limited productivity. Solar energy offers a viable alternative by providing reliable and decentralised power for irrigation, significant reduction in costs as an alternative to diesel, lower carbon emissions addressing climate concerns and opportunities for additional income through surplus power generation. Solarisation not only promotes climate friendly farming but also strengthens the income of rural livelihoods
Renewable Energy Towards Sustainability
No full textEnergy is the basic necessity for human being to survive. Demand for daily energy requirements creates pressure on finite source of fossil fuel based energy, which is rapidly declining in different parts of the world. Agriculture is one sector, which consumes about 7-8% of total energy consumption of India. Pumping of irrigation water, use of heavy machineries for different farm operations, processing and value addition of farm produces etc. are major activities by which energy is consumed in agriculture sector. With the advancement of food production system from agrarian to a futuristic technology-driven system, there has been rapid increase in energy use in agriculture Agriculture sector has great scope in meeting this renewable energy target of the country and can be achieved through major two ways viz., the replacement of fossil fuel based farm operations with renewable energy sources and second is the contribution in renewable energy generation from agriculture sector
