WAEC AGRIC SPECIMEN & GUIDELINES
▪ SPECIMEN A – Ammonium Sulphate (Labelled)
Description: A white crystalline inorganic fertilizer.
Importance/Uses :
i. Supplies nitrogen to plants, essential for leaf and stem growth.
ii. Improves soil fertility, especially in alkaline soils (it’s slightly acidic).
iii. Commonly used in vegetables, cereals, and pastures.
▪ SPECIMEN B – Muriate of Potash (Labelled)
Description: Also known as potassium chloride (KCl), a reddish or white salt.
WAEC 2025 AGRIC PRATICAL SPECIMENS
Importance/Uses :
i. Rich in potassium, essential for fruit development and disease resistance.
ii. Promotes root development and water regulation.
iii. Used in root crops like cassava and potatoes.
▪ SPECIMEN C – Cow Dung
Description: Animal waste excreta, often used in raw or composted form.
Importance/Uses :
i. Acts as organic manure, improving soil structure and microbial activity.
ii. ncreases water retention and fertility in poor soils.
iii. Used in biogas production and organic farming.
▪ SPECIMEN D – Compost (Labelled)
Description : Decomposed organic matter from plant and animal remains.
Importance/Uses :
i. Serves as natural fertilizer, returning nutrients to the soil.
ii. Enhances soil texture and moisture-holding capacity.
iii. Encourages sustainable farming by reducing chemical input.
▪ SPECIMEN E – Cutlass
Description: A handheld cutting tool with a broad blade.
Importance/Uses:
i. Used for clearing bushes, weeding, and harvesting crops.
ii. Essential in manual farm operations, especially in small-scale farms.
iii. Aids in land preparation before planting.
▪ SPECIMEN F – Spade
Description: A digging tool with a flat, broad blade and long handle.
Importance/Uses:
i. Used for digging, turning, and lifting soil.
ii. Helps in planting, transplanting, and soil amendment.
iii. A key tool in nursery and garden maintenance.
▪ SPECIMEN G – Wheelbarrow
Description: A one-wheeled cart for transporting loads.
Importance/Uses:
i. Used for carrying soil, manure, tools, and harvested crops.
ii. Reduces manual labor and increases efficiency.
iii. Essential in construction and landscaping on farms.
▪ SPECIMEN H – Yam Beetle
Description: A destructive insect pest that bores into yam tubers.
Importance/Uses:
i. Demonstrates pest damage symptoms on crops.
ii. Aids in teaching integrated pest management (IPM).
iii. Important for studying post-harvest loss in yams.
▪ SPECIMEN I – Cowpea Weevil
Description: A beetle that infests cowpea seeds in storage.
Importance/Uses:
i. Used to study storage pests and infestation.
ii. Helps in learning preventive and control measures like airtight storage.
iii. Demonstrates effects of poor storage practices on legumes.
▪ SPECIMEN J – Centrosema pubescens
Description: A creeping leguminous cover crop with purple flowers.
Importance/Uses:
i. Used for soil cover and erosion control.
ii. Improves soil nitrogen content through nitrogen fixation.
iii. Serves as forage for livestock.
▪ SPECIMEN K – Spear Grass
Description: A common perennial weed with spear-like sharp tips.
Importance/Uses:
I. Used to teach weed identification.
ii. Helps in understanding weed control strategies.
iii. Demonstrates competition between crops and weeds.
▪ SPECIMEN L – Gizzard (Chicken)
Description: A muscular part of a bird’s digestive system.
Importance/Uses:
i. Shows adaptations of poultry for grinding food.
ii. Helps in explaining mechanical digestion in birds.
iii. Important in comparative anatomy with mammals.
▪ SPECIMEN M – Goat Skin (Fresh, With Hairs Intact)
Description: Skin from a goat, unprocessed, with hair.
Importance/Uses:
i. Used to explain structure and functions of animal skin.
ii. Demonstrates adaptations to the environment (e.g., hair for protection).
iii. Used to teach about hide and leather processing.
▪ SPECIMEN N – Horn
Description: A hard, pointed projection from the head of animals like goats or cattle.
