Waec Model Questions Vol1 2022 Agricultural Science Question 3 diagram

A farmer is using a hand hoe to prepare a rectangular plot of land. The plot measures 10 m in length and 5 m in width. The farmer starts at one corner and works in parallel rows 0.5 m apart, moving the hoe forward 1 m and then returning along the next row. A stopwatch records that the farmer completes the entire plot in 2 hours 30 minutes. The soil moisture meter reads 12 % at the start and 10 % at the end, indicating a slight reduction due to tillage.

Question Parts

( a )
Calculate the total area cultivated per hour by the farmer.
( b )
A motorised tiller can prepare the same plot in 45 minutes but consumes 4 L of diesel at ₦180 per litre. Assuming a manual labour wage of ₦150 per hour, compare the cost of the hand‑hoe method with the fuel cost of the tiller and state which method is more economical.
( c )
Discuss two agronomic advantages of using a motorised tiller over a hand hoe in this context.
