Jute is primarily cultivated during the Kharif season in Assam. Kharif is the rainy season in India, which runs from June to October. Jute is a tropical plant that requires a lot of water to grow, so it is planted during the monsoon season. The main jute-growing areas in Assam are the Brahmaputra Valley and the Barak Valley. The Brahmaputra Valley is the largest jute-growing area in India, accounting for about 60% of the country’s jute production. The Barak Valley is the second largest jute-growing area in India, accounting for about 20% of the country’s jute production.
The other options are incorrect because they are not the rainy season in India. Rabi is the winter season, which runs from November to March. Zaid is the summer season, which runs from April to May. Winter is not a suitable season for growing jute because it does not receive enough rainfall.
