Cotton is a fibre crop and an important commercial item in AP's crop mix. Official district lists for Guntur, Krishna and Ananthapuramu include it. The harvested lint connects agriculture to ginning, spinning and textile industry; Guntur's district page notes cotton ginning and spinning mills. This makes cotton a useful bridge between agriculture and the later Minerals, Industries and Ports book.
Cotton can be sensitive to rainfall, pests, seed choice and market price. An exam may use the phrase “black cotton soil,” but the soil's name is not proof that every cotton field is on one soil type. A district's current area and yield need the crop year. Keep cotton distinct from jute, sugarcane and paddy by product: lint is fibre, sugarcane is a sugar crop, and paddy is a cereal grain. An intercropping example with redgram belongs to agronomic practice, not the definition of cotton.
Worked example: Cotton is a fibre and commercial crop. An MCQ may contrast it with paddy, chilli and groundnut to test crop class. A cotton gin and a planted field can be in different districts, so a processing unit does not prove local acreage. For a yield question, use seed-cotton and lint terminology carefully and preserve the unit supplied by the source.
Active recall: Match cotton to crop class, harvested product and one AP district page that lists it.
