2.1 INTRODUCTION

Before the introduction of seed sowing machine, most seeds are planted by hand broadcasting, an impressive and wasteful process with a poor distribution of seeds and low productivity. With the help of seed sowing machine, seeds are distributed in rows however distance between each seed can be adjusted. This allows plants to get sufficient sunlight, nutrients and water from the soil. Before the operation of the seed drill, the ground must be plowed and harrowed. The use of seed sowing machine saves time of labour.

2.2.1 NEED STATEMENT

A seed sowing machine is a device that sows the seeds by positioning them in the soil and burying them to a specific depth, ensuring that the seeds are covered by soil.
