General Information

:

The gorru consists of a simple frame on which hitch bracket, handle, furrow openers and furrow closure are mounted. The furrow openers are very similar to country plough having adjustable / replaceable share points. A square bar provided at the rear covers the seed which can be easily lifted by means of a rope when clods or trashes are accumulated. Two bowls each having three holes are mounted at a convenient height for manually metering the seeds and fertilizers respectively. The three holes of the each bowl are connected to the three furrow openers by plastic pipes. Provision is made in the furrow openers to place the seed and fertilizer side by side and at different depths. The seed and fertilizer rates and their uniformity in the rows depend mainly on the skill of the operators. Three persons are required, one to operate the unit, one to meter the fertilizer and the other to meter the seeds.
