Neco 2017 Agricultural Science Question 6
Practice objective / multiple choice question 6 from the 2017 Neco Agricultural Science examination.
A farmer has two ploughs. The single‑bottom plough requires a draft of \(150\) N per metre width, and its working width is \(0.30\) m. The three‑bottom plough requires \(400\) N per metre width and its working width is \(0.90\) m. The field area is 5 ha (\(50\,000\) m\(^2\)) and the soil moisture adds \(10\%\) to the draft force. Fuel consumption is proportional to the product of draft force and distance travelled. The single‑bottom plough can till 1 ha per hour, while the three‑bottom plough's speed is reduced by \(20\%\) because of the heavier draft. Which plough will use less fuel to till the whole field? Show your calculations.
