Neco 2021 Agricultural Science Question 3 diagram

The diagram shows three commonly used farm hand tools arranged on a wooden board. Tool A is a hand hoe, Tool B is a garden fork, and Tool C is a shovel. The dimensions of the handles and the angles between the handle and the blade are indicated.

Question Parts

( a )
List the three main parts of each tool as labelled in the diagram.
( b )
For each tool, describe a farming operation where it is most effective and justify why its design is suitable for that operation.
( c )
The farmer records that using the hand hoe (Tool A) reduces the time required to break up a 0.5 ha plot from 8 hours (when using a simple spade) to 5 hours. Assuming labour cost is ₦150 per hour, calculate the monetary saving per hectare when the hand hoe is used instead of the spade. Also, if the hand hoe costs ₦12,000 and has a useful life of 4 years with 150 working days per year, determine the daily depreciation cost and state whether the saving per day justifies the purchase.
