DEVELOPMENT AND TESTING OF A MANUALLY OPERATED PADDY DIBBLER

Abstract

A manually operated three row paddy dibbler for dry sowing of paddy has been developed and tested. When the dibbler operated. the roller passing vertically through the centre of seed box would move upward by the soil pressure against the spring pressure. As the roller moves upward. the portion of the roller having the vertical slot would come in contact w1th seeds which arc then moved and earned to this slot. When the equipment is taken out from the soil. the soil pressure on the roller is released and due to the spring pressure, the roller moves downward and the seeds in the slot are released and fall through the seed tube by gravity into the soil. The number of seeds dropped arc in the range of 4 to 6 per hill. The area covered by the dibbler is 0.022 ha/h with a field efficiency of 68%.
