Q1. The major soybean-producing region of Rajasthan is:
A Semi-Arid
B Hadoti Plateau Correct
C Mahi Basin
D Eastern Plains
Explanation
Rajasthan's main soybean belt lies in the Hadoti Plateau, especially around Kota, Bundi, Baran and Jhalawar, where rainfall and black-soil conditions support the crop. The semi-arid region is more associated with hardy dryland crops and oilseeds suited to lower rainfall. The Mahi Basin is important for irrigated agriculture in the south, but it is not the principal soybean-producing region of the state. The Eastern Plains grow several crops, yet soybean concentration is strongest in Hadoti. Hence the answer is Hadoti Plateau.
