Explanation:

Ans. Boro 

Kharif Rice in WB is known as Boro . Boro rice is cultivated in waterlogged, low-lying or medium lands with irrigation during November to May. This type of rice has been cultivated traditionally in river basin deltas of Bangladesh and Eastern India including Eastern U.P., Bihar, West Bengal and Assam. In these regions, water accumulates during monsoon months and cannot be drained out in winter months. This practice is spreading even to those non-traditional areas where irrigation is available.
