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

I: Incubator
Uses: It is used for hatching eggs by providing a controlled environment with a specific temperature and humidity.

II: Panga
Uses: It is often used for cutting vegetation, clearing land, and harvesting crops.

III: Syringe and Needles
Uses: It is used for administering medications, vaccines, or other medical treatments.

IV: Feedrack
Uses: It is used to hold and dispense animal feed

V: Weighing Balance
Uses: It is used to measure quantities of seeds, fertilizers, or other materials, ensuring accurate and consistent application in farming practices

Seeds are sown in individual cells of the tray, allowing for organized growth and easy transplanting. The tray helps in maintaining optimal moisture, temperature, and spacing conditions, promoting healthy seedling development 'copied from e x p o c o d e . n e t free' before they are ready to be transplanted into the field or larger containers.

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
