Manually Operated Seed Sowing Machine

Agriculture in developing countries still relies heavily on traditional methods of seed sowing, which are labor- intensive, time-consuming, and often result in non-uniform seed distribution. To address these limitations, this research focuses on the design and development of a manually operated seed sowing machine that is economical, simple to operate, and suitable for small and marginal farmers. The proposed machine aims to improve sowing efficiency by ensuring uniform seed placement, proper spacing, and controlled depth of sowing while reducing human effort and operational time. The design incorporates key components such as a seed hopper, metering mechanism, furrow opener, seed delivery tube, and ground-driven wheel mechanism. Standard engineering design principles and material selection criteria were applied to achieve durability, ease of maintenance, and low manufacturing cost. Performance evaluation of the developed prototype was conducted under field conditions, and results indicate improved seed placement accuracy, reduced labor requirement, and higher field efficiency compared to traditional manual sowing methods. The developed manually operated seed sowing machine offers a practical and sustainable solution for enhancing agricultural productivity in resource-limited farming environments.
