Agro technology:
Soil and climate: Climate is tropical with rainfall 500-750 mm. It can be grown in a wide variety of soils.
Propagation: Cotton is mostly propagated by seeds. It can be propagated vegetatively by cuttings.
Manure: Apply Farm yard manure compost 12.5 t/ha for rainfed crop. Apply N: P2O5: K2O each 35 kg/ha as basal dressing.
Irrigation: Irrigate the plants once in two weeks. Copious irrigation during flowering will ensure good pod setting and good fibre quality.
Plant protection: Sucking pests like jassids, aphids, and thrips are attacking the plant. Main diseases are bacterial blight diseases, and Alternaria leaf spots.
Harvesting: The bolls start bursting 100-120 days after sowing and will be ready for harvest at this stage. This crop is usually harvested in 3 or 4 pickings, taken at suitable intervals. Harvesting from half – open or immature bolls yields cotton containing large percentage of immature fibres and trash.
