Question 4 WAEC_MODEL_QUESTIONS_VOL1 • 2018 • AGRICULTURAL_SCIENCE • practical

A small diesel‑engine tractor is employed for primary tillage on a 5‑hectare farm. The tractor pulls a 2‑point plough with a total working width of 2.4 m. It is driven at a forward speed of 5 km h⁻¹ and the field efficiency is estimated at 75 %. The tractor’s fuel consumption at this load is 5 L h⁻¹. Diesel costs ₦180 per litre.

Question Parts

( a )
Calculate the theoretical field capacity (ha h⁻¹) of the tractor using the formula: Capacity = (Width (m) × Speed (km h⁻¹) × Field Efficiency) ÷ 10.
( b )
Determine the total time (in hours) required to till the entire 5‑ha field, assuming the calculated capacity is maintained throughout.
( c )
Calculate the total volume of diesel fuel required for the operation and the corresponding cost in naira.
( d )
i) List two advantages of using this tractor for tillage compared with animal‑drawn ploughing.\nii) List two disadvantages.\niii) Recommend one routine maintenance practice that can improve the tractor’s fuel efficiency, and briefly explain how it helps.
