Soil Requirement: Ginger grows best in deep, fertile, well-drained loamy soil rich in organic matter with a pH of about 5.5 to 6.5.

(4aii)
Land Preparation: The land is cleared, ploughed, harrowed, and ridged or raised into beds before planting.

(4aiii)
Planting Material: Healthy and disease-free rhizomes with viable buds are used for planting.

(4aiv)
Spacing: Ginger is commonly planted at a spacing of 30 cm × 30 cm.

(4av)
Method of Harvesting: Ginger is harvested by carefully digging up the rhizomes from the soil using hoes, forks, or cutlasses.

(4avi)
(PICK TWO ONLY)
(i) Washing the harvested rhizomes.
(ii) Peeling or scraping off the outer skin.
(iii) Slicing or cutting into smaller pieces.
(iv) Drying under the sun or in dryers.

(4bi)
Area of Farmland:
A = 1/2 × (a + b) × h
A = 1/2 × (46 + 60) × 30
A = 1/2 × 106 × 30
A = 53 × 30
A = 1590 m²

(4bii)
Spacing area per hole = 30 cm × 30 cm
= 0.30 m × 0.30 m
= 0.09 m²
Number of holes = Total area ÷ Area per hole
= 1590 ÷ 0.09
= 17666.67
≈ 17667 Stands
