Abstract EN

A factorial experiment with RCBD was conducted to test the developed manual planter-fertilizer and compare it with undeveloped manual planter-fertilizer and hand method for planting different crops: Okra, Cotton, Zeymays and Sunflower.

Productivity, time of planting, broken seed percent and emergence percent, were studied in this experiment.

The developed of cotton manual planter-fertilizer has been carried out by many modification for all tool parts .The old tool should be fixed on the place where seed should be plant by pressing it by hand to drill seed bed, but the developed tool works to push the seeds and fertilizers in the same time while it moves simply by hand on soil by tires.

In the method we don’t used high work to seeding and controlling the seeds depth easly in the soil.

The results showed that tool productivity (hectare / hr) of the developed tool was increased by 263 % from the old tool and by 700 % from the manual method, the time of seeds planting for one hectare was reduced to 72 °A hours by developed tool while it takes 80 % by old tool, broken seeds percent were reduced in both tools to zero and.

Seed emergence % of the developed tool was increased by 7 % from the manual method and by 4.4 % from the old tool.

The results showed that significant differences for fertilizer or fertilizer and planter between old and development tool and manual method.

The crops did not have a significant effect on seed emergency, ratio of broken seed, productivity, time.
