Development of a power tiller operated paddy transplanter for conventional seedlings

Abstract

Transplanting of paddy seedlings is a very tiresome and labour consuming operation and labour shortage is experienced during planting. As a solution to reduce the high cost of cultivation and labour shortage in paddy transplanting, a power tiller operated paddy transplanter is an essential need of hour. The APAU paddy transplanter was evaluated after rectifying the defects at KCAET instructional farm, Tavanur.

Based on the field experiences and considering the all problems in APAU paddy transplanter, an improved version of power tiller operated paddy transplanter was developed and fabricated at KCAET Tavanur and tested during September-October 1994. The convensional root washed paddy seedlings ready to manual transplanting were used. When the power tiller is operated at a forward speed of 1.20 km per hr, the transplanter could transplant 2 to 4 seedlings per hill at a spacing of 100 to 120 mm. The average field capacity was found to be 0.13 ha per hr. A saving of Rs.800 per ha which is 50 per cent and reduction of 296 man-hr per ha which is 92.5 per cent was achieved for transplanting operation alone compared to manual transplanting.
