AGRICULTURAL MECHANIZATION
HND 2015
Agricultural mechanization involves the use of machines for the provision of mechanized assistance
to agricultural production to reduce drudgery and bring more land under cultivation. A young
entrepreneur from the College of Agriculture Bafangreceives a support grant from the AFOP
program at the end of his training and decides to relocate the North West Region in order to start up
a maize farm. The entrepreneur finally settles in the Menchum area where many farmers have been
using animal traction for their crop production. The government of Cameroon had also created the
Wum Area Development Authority (WADA) in this area to boost agricultural production. WADA has
been equipped with tractors, tillage implements, combines, sprayers and other implements to ease
access to machines for people of this area. In order to diversify resources, apart from owning a
maize farm, the entrepreneur soon decides to attach extension services to other farmers and a
poultry production unit of 450 broiler birds.
a) Despite government efforts to change the state of mechanization in Cameroon, the level is
still relatively low. Explain four factors which could attribute to this low level of
mechanization. 4 pts
b) If a farmer in the area decides to seek advice on how to procure new draught animals.
Explain 4 criteria that the entrepreneur should advice the farmer to use in choosing his

d) Ownership of tractor involves two main costs. Give the two main cost items and two
elements each to be considered in each cost item. 2 pts
e) For the protection of the crops against pests as well as the protection of the birds against
diseases, the enterprise uses some chemicals. Give four precautions to be followed when
using chemical on the farm. 2 pts
f) The maize to be used in the production of feed is stored in a small crib to be designed by the
entrepreneur. Explain 4 design factors he should consider in his construction. 2pts
g) Given that the poultry house to be constructed will measure 8m by 3m by 3m, calculate the
number of blocks to be ordered if he intends to use blocks of size 20cmby10cm for the four
walls. 1pt
