Step 1: Geographical Factor - Favorable Climate.
The geographical factor responsible for West Bengal being the leading producer of jute is its favorable climate. The state has a humid tropical climate, which is ideal for the cultivation of jute. The warm and wet weather, especially during the monsoon season, provides the necessary conditions for jute to thrive.
Step 2: Soil Conditions.
Additionally, the alluvial soil found in the region, particularly along the banks of the Ganges and other rivers, is rich in nutrients and supports the healthy growth of jute crops.
