The progress of the monsoon is being closely monitored this year due to fears of the El Nino weather pattern, associated with scarce and highly uneven rainfall.India gets 75-80% of annual rainfall during the four-month long monsoon season, crucial for the planting of major crops such as paddy, pulses, and oilseeds.The kharif season, which starts in June, accounts for more than half of India's foodgrain production and its outcome is crucial for food inflation.
