Kharif Crops- cultivation and harvesting of any domesticated plant sown in the rainy (monsoon) season on the Asian subcontinent. Such crops are planted for autumn harvest and may also be called the summer or monsoon crop in India and Pakistan. Kharif crops are usually sown with the beginning of the first rains in July, during the south-west monsoon season. In Pakistan the kharif season starts on April 16 and lasts until October 15. In India the kharif season varies by crop and state, with kharif starting at the earliest in May and ending at the latest in January, but is popularly considered to start in June and to end in October. Examples include Millet, Paddy, etc.
Rabi Crops-refers to agriculture crops sown in winter and harvested in the spring. It is the spring harvest (also known as the "winter crop") in Indian subcontinent.The rabi crops are grown between the months mid November to April. The main Rabi crop is wheat.The water that has percoalted in the ground during the rains is main source of water for these crops. Rabi crops require Irrigation.So a good or bountiful rain may tend to spoil the Kharif Crops but it is good for Rabi crops.These crops are taken after the departure of monsoon rains. The seeds are sown after the rains have gone and harvesting begins in April/May.Major Rabi crop is wheat in India followed by barley, mustard and peas.
