Abstract: India is an agricultural country where small and marginal land holding farmers cultivate around 44 per cent of the area, and they involve in production of 60 percent of total food grain. So, there is need to develop precision machines, suitable for small farm. In check row planting, row-to-row distance is equal to plant-to-plant distance. Check row planting is an essential part of precision agriculture, which allows weeding in both directions and sunlight up to the bottom of the crop. The existing planters have the problems of misalignment of seeds along the transverse direction due to slippage of the ground wheel. It is also difficult to move the planter straight between the swath during planting operation. In order to overcome these limitations of existing planter, an electro-hydraulic row guiding system assisted check row planter with electronic metering unit was designed and developed. The hydraulically operated row guiding system was designed on the basis of force requirement to move the furrow opener through the soil while planting. The physical and mechanical properties of seeds were determined to design the seed metering system and seed box. The LIDAR distance sensor was used to sense the distance from the reflecting surface. The LIDAR sensor was calibrated in the laboratory and distance measured by the LIDAR sensor was close to the Bosch laser distance sensor with mean deviation of 0.45 cm. The rotation of the stepper motor in the metering system was controlled by the microcontroller on the basis of signal received from the LIDAR sensor at set distance. The performance parameters of the metering system were calculated at five different cell size (8.80, 9.73, 10.82, 11.90 and 12.83 mm) and cell speed (89.15, 99.46, 111.44, 123.41 and 133.72 mm.s-1 ). The average seed spacing was close to theoretical seed spacing for cell size of 11.90 mm and cell speed of 99.46 mm.s-1 . Multiple index, miss index and precision increased with increase in cell speed while the quality of feed index decreased with increase in cell speed. The optimised values for the cell size, cell speed, mean spacing, quality of feed index, multiple index, miss index and precision were found to be 11.90 mm, 99.46 mm.s-1 , 541.58 mm, 81.16%, 10.22%, 8.62% and 19.35% respectively. The check row planter was developed and assembled with the row guiding system. The prototype planter was tested in the field and different performance parameters were measured. The actual field capacity and field efficiency of the planter were 0.12 ha.h-1 and 75.2% respectively. The field machine index for the planter was 72.72 percent. The mean seed spacing along the row and across the rows were found as 40.32 cm and 41.25 cm respectively in field condition. The developed planter saves 84% of cost of operation over manual check row planting of maize. Keywords: Check row planting, Row guiding system, Electronic metering mechanism and LIDAR sensor.
