A farmer is evaluating the purchase of a 15‑horsepower (hp) tractor to operate a 3‑point‑hitch‑mounted disc plough for preparing a 10‑hectare field. The plough has a working width of 1.2 m. The tractor can maintain a forward speed of 5 km h⁻¹ in the field. Because of turning, overlap and other losses, the overall field efficiency is 75 %. Fuel consumption of the tractor at this load is 5 L h⁻¹ and diesel costs ₦250 per litre. Manual labour cost for preparing the same field with a hand plough is ₦1 200 per hectare. Additional data: - Purchase price of the tractor: ₦1 200 000. - Service life: 5 years (straight‑line depreciation). - Annual maintenance cost: 5 % of the purchase price. - The tractor will be used only for field preparation on 120 days per year. Using the information above, answer the following:

Question Parts

( a )
Calculate the field capacity (in hectares per hour) of the tractor‑plough combination.
( b )
Determine the total fuel cost for preparing the 10‑hectare field once.
( c )
Compute the total cost per hectare of using the tractor for one season, including fuel, depreciation and annual maintenance. Assume straight‑line depreciation and that the tractor is used only for this operation each day.
( d )
Compare the tractor cost per hectare with the manual labour cost (₦1 200 ha⁻¹) and advise whether the purchase is economically justified for the first five years. Provide a brief justification.
