DEVELOPMENT AND EVALUATION OF SELF- PROPELLED DRUM SEEDER MISRIYA K; AMNA K; FEMINA BANU K C; Edwin Benjamin, (Guide) Rice cultivation is increasingly affected by labour scarcity, rising production costs, water stress, and the limitations of conventional transplanted rice systems. Direct seeded rice (DSR) has emerged as a promising alternative due to reduced labour requirement, lower water consumption, and timely crop establishment. Among DSR methods, drum seeding of pre-germinated paddy is widely practiced, but the conventional manually operated drum seeder causes operator fatigue and has limited field capacity. To overcome these limitations, the present study entitled “Development of Self-Propelled Drum Seeder” was conducted at the Department of Farm Machinery and Power Engineering, KCAEFT, Tavanur. The study aimed to determine the physical and engineering properties of paddy seeds, optimize seeding parameters under laboratory conditions, develop a self-propelled drum seeder, and evaluate its field performance. Two rice varieties, Jyothi and Uma, were selected for the study. A laboratory test rig with a sticky belt mechanism driven by a variable frequency drive was fabricated to simulate different forward speeds. A factorial experiment was conducted to study the effects of variety, hole diameter, hole spacing, and forward speed on seeding performance parameters. The results showed that seeding performance was significantly influenced by the interaction of these factors. Among the combinations tested, the Uma variety with 9 mm hole diameter, 80 mm hole spacing, and 1.5 km/h forward speed was identified as the optimum configuration based on overall seeding performance. Based on these optimized parameters, a self- propelled drum seeder was developed by integrating a walk-behind power unit fitted with a 1.5 hp two-stroke petrol engine with a manually operated eight-row drum seeder. Field evaluation of the developed machine under puddled conditions showed an effective field capacity of 0.17 ha/h, field efficiency of 70.83%, fuel consumption of 0.28 L/h, and actual seed rate of 54.3 kg/ha. The study concluded that the developed self-propelled drum seeder effectively reduced operator drudgery while maintaining efficient seed metering, making it a practical and low-cost mechanized solution for wet direct seeding of paddy in small and fragmented fields

SEMI-AUTOMATIC GROWBAG FILLING MACHINE BINJU MS; NAJMA FARSANA T; AMRITHA S; Dipak Suresh Khatawkar, (Guide) Growbag cultivation has emerged as a significant component of protected agriculture, particularly for vegetable and seedling nurseries. However, manual growbag filling is a highly labour-intensive and ergonomically demanding operation that creates labour bottlenecks, causes inconsistent fill weights, and exposes workers to musculoskeletal injury risks. While fully automatic filling machines exist, their high commercial costs make them economically unfeasible for small- and medium-scale nurseries. To bridge this technology adoption gap, a study was undertaken to design, develop, and evaluate a sensor-based, semi-automatic growbag filling machine tailored to the operational needs of local nursery operators. The machine's structural components were engineered based on the physical characterization of a standard 1:1:1 volumetric potting mixture of soil, coir pith, and farmyard manure. This mixture exhibited a total porosity of 24.49%, and an angle of repose of 60°. The machine utilizes a volumetric cell metering mechanism consisting of four cylindrical mild steel cups driven at 90° intervals, working in tandem with a rotating turntable platform that features eight growbag holder positions spaced at 45° intervals. The control automation circuit integrates industrial-grade motion controllers with an optical feedback loop managed by an Arduino microcontroller. Power transmission to the turntable is driven by a high-torque NEMA 23 planetary geared stepper motor and an ES-D1008 servo drive, connected via a flexible jaw coupling to dampen mechanical vibrations. Position tracking and bag detection at the filling station are accomplished using a TCS3200 RGB colour sensor module. Upon validating bag presence, the microcontroller executes non-blocking timing logic to actuate the metering gate, discharging a precise volume of substrate before advancing the turntable to the next position. Performance evaluation of the fabricated machine demonstrated high functional reliability and operational efficiency under field conditions. The automated system achieved a stable throughput of 500 bags per hour, representing a significant improvement over manual rates while reducing operator fatigue. Volumetric filling consistency was high. Built using standard materials and off-the-shelf electronic components, the total cost of fabrication is about 45,000, presenting nursery entrepreneurs with an accessible and economically viable alternative to manual labour
