| Abstract | ||||
| Experiments were carried out to manufacture and evaluate the performance of a combination unit suitable for water harvesting, planting, and soil conservation under rain fed agricultural conditions. The machine performance was studied as a function of change in machine forward speed and plowing depth. Performance evaluation of the manufactured machine was carried out in terms of bulk density, and infiltration rate as a soil measurements; crop yield as a crop measurements; runoff and water use efficiency as a water measurements; field capacity and efficiency, required power, energy requirements and operational cost as a machine measurements. The experimental results reveal that runoff volume, energy and cost were minimum while crop yield was maximum under the following conditions: - The use of the developed unit for effective water harvesting and soil conservation. - Machine forward speed of between 3.5 to 4.5 km/h. - Plowing depth of between 10 to 15 cm. | ||||
