(4a) Cotton Cultivation
(i) Planting Material
Cotton is typically planted using seeds. High-quality seeds are essential for optimal germination and yield.

(ii) Spacing
Proper spacing (usually 30-100 cm between rows and 10-30 cm between plants) ensures adequate sunlight, air circulation, and nutrient uptake.

(iii) Two Varieties
(i)Upland cotton (Gossypium hirsutum) Most widely cultivated, suitable for various climates.
(iii)Pima cotton (Gossypium barbadense): Known for extra-long staple fibers, often used for high-quality textiles.

(iv) Harvesting
Cotton is usually harvested using mechanical pickers or hand-picking, depending on the scale and type of cultivation.
(v)
(i)Bollworms : Larvae that feed on cotton bolls, causing damage.
(ii)Aphids : Small insects that suck sap, potentially transmitting diseases.

(vi)
(i)Textiles Cotton fibers are used to produce clothing, bedding, and other fabric products.
(ii) Oil productionCottonseed oil is used in cooking, cosmetics, and industrial applications.

(4b)
(i)Improved yield: New varieties may offer higher yields, increasingBollworms*: Larvae that feed on cotton bolls, causing damage.
(ii)Aphids : Small insects that suck sap, potentially transmitting diseases. productivity.
(ii)Disease resistance : Some new varieties may be resistant to specific diseases, reducing pesticide use.
