2023 WAEC GCE AGRICULTURAL SCIENCE PRACTICAL ANSWERS:
(1a)
A - Clay soil
B- Sandy soil
(1b)
Sandy
(1ci)
Cylinder A:
Percentage of water retained = (Water collected / Water added) x 100
= (10 cm³ / 30 cm³) x 100
= 33.33%
(1cii)
Cylinder B:
Percentage of water retained = (Water collected / Water added) x 100
= (25 cm³ / 30 cm³) x 100
= 83.33%
(1d)
(PICK ANY TWO FROM EACH)
A - wheat, barley,oats
B - Carrots, radishes, sweet potatoes
(2a)

(2b)
The seeds are planted in the farm tool containing the required soil. The set up is placed in the sun with frequent supply of adequate water. After leaving for few weeks,the seeds starts to germinate and it's then transplanted to the field properly.
(3a)
The plant population of groundnut can be determined by using the formula:
Plant Population = Area of Farmland / Spacing
In the table, the area of farmland for groundnut is given as 3 hectares, and the spacing is given as 1m * 0.5m.
First, let's convert the area from hectares to square meters (1 hectare = 10,000 square meters):
Area of Farmland (in square meters) = 3 hectares × 10,000 square meters/hectare
=30,000 square meters
Now, we can use the formula:
Plant Population = 30,000 square meters / (1m × 0.5m)
Plant Population = 30,000 square meters / 0.5 square meters
Plant Population = 60,000
So, the plant population of groundnut is 60,000.
(3b)
To calculate the expected plant population for maize, we will use the formula:
Plant Population= (Area of Farmland)/(Spacing) × Germination Percentage
Given that the area of farmland for maize is 5 hectares (50000 square meters) and the spacing is 1m×1m, the formula becomes:
Plant Population= (50000/1×1) ×0.9
= 45000
