Kharif and Rabi Cropping Seasons

India’s kharif and rabi seasons are distinguished mainly by when crops are sown and the weather under which they grow. Kharif crops grow chiefly during the warm, rainy southwest monsoon, whereas rabi crops grow during the cool, relatively dry winter and mature in warmer spring or early summer conditions.

Kharif season: warm and rainy conditions

Kharif cultivation is closely linked to the onset, distribution and withdrawal of the southwest monsoon.

• Crops are generally sown with the beginning of rains in June-July and harvested in September-October, with regional variations.
• Most kharif crops require relatively high temperatures and humidity during growth, but their water needs differ considerably.
• Rice and jute generally need abundant water, while millets and pulses can tolerate comparatively drier conditions.
• Delayed, deficient or poorly distributed rainfall can reduce sowing and yields; floods and prolonged waterlogging may also damage crops.

Rabi season: cool growth and dry maturation

Rabi crops rely on cool winter conditions for vegetative growth and generally benefit from warm, dry weather during ripening and harvesting.

• They are generally sown from October to December and harvested from April to June, depending on crop and region.
• Because winter rainfall is limited over much of India, rabi farming often depends on irrigation or moisture retained in the soil after the monsoon.
• Light winter rainfall associated with western disturbances can benefit wheat and other rabi crops in northwestern India.
• Unseasonal rain, hail or excessive heat near maturity can damage grain formation and harvesting.

Core climatic contrast

• Kharif production is more directly dependent on the timing and spatial distribution of monsoon rainfall, while rabi production is more dependent on winter temperature, stored soil moisture and irrigation.
• Typical kharif crops include rice, maize, cotton, millets and groundnut; typical rabi crops include wheat, gram, peas, mustard and barley.
