“…This technology's seed placement precision is critical for achieving optimal plant growth and yield. Ryu and Kim (1998) [7] designed a roller-type metering device that improved the uniformity of seed placements across various crops. This precision is particularly impactful in reducing seed waste and improving crop yields.…”

This review systematically analyses belt-type battery-operated seed metering mechanisms within precision agricultural planters, providing a critical comparison with traditional seed metering technologies. Utilizing studies from 1970 to 2023 sourced from databases like Scopus and IEEE Xplore, this paper explores these mechanisms' technological advancements, design variations, and operational efficiencies. Belt-type mechanisms offer adaptability across various seed sizes and environmental conditions, significantly reducing seed damage. In contrast, battery-operated mechanisms provide crucial benefits in portability and flexibility, making them especially suitable for precision planting in remote areas. Both technologies have been found to enhance seed placement accuracy, streamline operational processes, and offer substantial labour savings over conventional methods. However, they also face specific challenges, such as belt types, mechanical speed limitations and battery-operated systems' energy dependency. The review underscores the need for future research to enhance system durability, increase adaptability to diverse agricultural needs, and improve the energy efficiency of these planting technologies. These improvements are essential for advancing precision planters' capabilities and meeting modern agriculture's increasing demands.

“…The measurement of physical properties showed the mean length of the seed as 5.58±0.20 mm, however, the variation in the maximum dimension of length was noted in the range of 5.51 mm to 5.87 mm. The size and shape of the cells of the metering plate were designed considering the design parameters used" [12]. Fig.…”

An investigation was conducted with the aim of examining the physical and engineering properties of okra seeds. The physical and frictional characteristics of okra seeds play a crucial role in the design of a seeder, influencing decisions regarding cell size, shape, metering disc thickness, and material, as well as the inclination of the seed hopper. The study aimed to determine these properties of okra seeds. The primary findings indicated that the typical values for the length, width, and thickness of the seeds were 5.58 mm, 4.61 mm, and 4.18 mm, respectively. The maximum width and length of the seeds served as the basis for the design of the cell diameters and thickness of the seed metering rotor. The okra variety “VNR-Deepika” exhibited a geometric mean diameter of 4.79 mm, with sphericity and roundness values of 85.2% and 82.85%, respectively. The roundness and sphericity of the seed affected its ability to move through the seeder's components. Test weight, bulk density, true density, volume, porosity, angle of repose, and coefficient of static friction were measured as 57.06 g, 0.56 g cm-3, 1.12 g cm-3, 111.46 mm-3, 50.22%, 25.97° and 0.42, respectively. The depth of the vertical rotor cells was established at 6.25 mm, slightly exceeding the average seed length to ensure singular seed dispensing. Simultaneously, the width of each cell was calculated to be 6.98 mm, offering adequate space for accommodating one seed per cell. Featuring 14 cells positioned around the vertical rotor's circumference, the seed metering rotor was designed to have an 85 mm diameter.

“…Research has been conducted to enhance planting performance not only in garlic but also in other crops [11][12][13][14][15][16][17]. However, studies that utilized experimental approaches have limitations in design variables or operating conditions and are applicable only within specific sample ranges [3,[5][6][7].…”

In this study, the discrete element method was used to optimize the bucket size for the metering device in a garlic planter for enhancing the productivity of garlic farming according to the garlic size. Statistical information concerning the actual shape of garlic cloves was incorporated, and the mechanical properties of garlic were determined using the bulk density, sliding test, and repose angle test for enhancing the fidelity of the simulation model. The optimal bucket size achieving the target plant rate of 97.5% was determined using the developed discrete element model for the three garlic size groups. The linear search method was used for optimization, and batch simulation was performed to validate the optimized results and confirm the performance index of the metering device. A Gaussian distribution based on statistical information accounted for the various garlic sizes in each group. Finally, a metering test verified the reliability of the optimization technique. The differences between the simulation and test results were within 10% for all performance indices, including missing plant rate, multi-plant rate, and planting rate, indicating the high reliability of the analysis model. Subsequently, the larger garlic groups (Groups 2 and 3) exhibited metering performance close to the target plant rate.
