Development and Evaluation of a Light Weight Power Tiller Operated Seed Drill for Hilly Region

摘要

A light weight power tiller operated seed drill was developed for sowing wheat in hilly terraces where vertical interval between terraces is high. Field trials were conducted at the university farm and at the farmers' field to determine the performance of the seed drill in comparison to the traditional method of sowing. The effective capacity of the machine was 0.09 ha/h with field efficiency about 74 %. The machine was efficient and economical as indicated by net saving of 78 % labor and 62 % cost of sowing over the traditional method.
