(a) Four farming operations requiring electric power

1. Pumping of water for irrigation.
2. Lighting and brooding in poultry houses, and incubation of eggs.
3. Milking with milking machines.
4. Grinding/milling of grains and feed, and refrigeration/cold storage of produce.

(b) Three advantages and three disadvantages of each farm power

(i) Electricity

Advantages:

• It is convenient and easy to use and control.
• It is efficient and reliable where supply is steady.

Disadvantages:

• It is not available in many rural farming areas.
• It is expensive to install.
• It is dangerous (risk of electrocution) and is affected by power failure.

(ii) Animal (draught) power

Advantages:

• It is cheap to acquire and requires no fuel.
• It provides manure and, ultimately, meat and hide.
• It is suitable for small farms and rough terrain.

Disadvantages:

• It is slow and gives low power output.
• It must be fed and cared for even when not working.
• It can work only for limited hours and may be lost to disease or death.
