Abstract
In India farm mechanization plays important role in achieving modernization in agriculture. But farmers suppose that mechanization means only use of self-propelled, robotics and tractor operated machinery while mechanization is the use of machinery that will let off the wedge labour and drudgery of farmers. Used machinery may be manual, animal drawn or self-propelled. Main power source available in India for small marginal farmers is of bullock power. About 82% of farmers belongs to small marginal land holding. Though there are very less bullock drawn machinery available and developed specially for sowing operation. Sowing is heart of whole agricultural practices hence needs precision while sowing, so that plant spacing is maintained. In case of Automatic precision planter power source is the bullock power and solar power so that small marginal farmers can afford, as no labour requirement and easy to operate. In order to maintain accuracy while planting mechanical transmission system replace by automatic transmission consist of Rotary encoder, PLC and Stepper motor and it also causes reduction in weight of machine (45 kg). Average draft requirement is of 52 kg. The theoretical field capacity actual field capacity and field efficiency of planter was 0.19 ha/hr, 0.165 ha/hr and 86.84% respectively. Average speed of operation was 2 km/hr. Average seed and fertilizer rate obtained is 69-78 kg/ha and 85-102 kg/ha respectively. Only one labour is sufficient to operate the planter.
