The lower Gangetic plain, with its humid climate and high temperatures, provides ideal conditions for the cultivation of paddy and jute due to their specific agronomic requirements. Paddy, being a water-intensive crop, thrives in the region's wet, low-lying fields, while jute prefers the warm and humid conditions that enhance its fibrous growth. Both crops are also well-suited to the alluvial soil found in this area, which is rich in nutrients essential for their development. This alignment of climate and soil conditions underscores the suitability of the chosen crop pair for the lower Gangetic plain, consistent with agricultural principles found in standard UPSC study materials.
