Cultural operations

Pruning of the shoot tips encourage tertiary branch growth, with many flowers and bolls. Increase in productivity up to 30% has been recorded through proper pruning.

Weed management

The first 2 months after sowing is crucial for cotton growth. Regular weeding at 25 days and 55 days after sowing is required. Mulching could be practiced to suppress weed growth. Sanitation of the field after weeding is necessary to prevent further occurrence.

Water requirements

Cotton requires very less water during its early stages of growth. Water requirement is essential during flowering and boll formation stage. The soil moisture should never go below 50% at any time. Black soil cultivation requires protective irrigation every 20 days in case of monsoon failure. Irrigation by furrow and alternate furrow method are most effective for cotton crops. Drip irrigation is also suitable. The use of mulches and other measures to reduce evaporation is however, recommended under rain-fed conditions.
