Q242. Sugarcane cultivation in Rajasthan is predominantly localized in which of the following pairs of districts?
Explanation
Sugarcane cultivation in Rajasthan is primarily concentrated in districts like Chittorgarh and Bundi. These areas have relatively better water availability and suitable soil conditions compared to the western desert. While sugarcane is grown in small pockets elsewhere, these districts provide the necessary environment for this water-intensive and long-duration crop, which is often linked to local sugar mill operations.
Q243. Which of the following pairs of Sugar Mills and their respective locations in Rajasthan is correctly matched?
Explanation
The Mewar Sugar Mills is located at Bhopal Sagar in the Chittorgarh district and was the first sugar mill established in Rajasthan. Other matches are incorrect; for example, the Rajasthan State Ganganagar Sugar Mills is located in Sri Ganganagar, and Keshoraipatan Sahakari Sugar Mills is in Bundi. These mills were historically important for processing the sugarcane grown in their command areas.
Q244. Which of the following statements about the climatic requirements for sugarcane in Rajasthan is incorrect?
Explanation
Hot, dry winds known as ‘Loo’ are actually harmful to sugarcane as they increase transpiration and can dry out the stalks, negatively impacting growth. Sugarcane prefers a humid, subtropical climate. While it needs warmth for growth and is damaged by frost during ripening, the presence of extreme dry winds during the summer is a major climatic constraint rather than a benefit.
Q245. What is the primary cause for the limited and declining area under sugarcane cultivation in Rajasthan?
Explanation
The primary reason for the declining area of sugarcane in Rajasthan is the increasing scarcity and cost of irrigation. As groundwater levels drop and water costs rise, growing a year-long, water-intensive crop like sugarcane becomes economically unviable for most farmers. Many have shifted to less demanding crops or those with shorter growing cycles that offer better returns on limited water resources.
Q246. Match the Spice Crops in List I with their Leading Producing Districts in Rajasthan in List II:
| Spice Crop | Leading Producing District |
|---|---|
| A. Coriander (Dhaniya) | i. Jalore / Barmer |
| B. Fenugreek (Methi) | ii. Nagaur |
| C. Cumin (Jeera) | iii. Baran / Jhalawar |
| D. Fennel (Saunf) | iv. Sirohi / Tonk |
Explanation
Coriander production is centered in the Hadoti region, specifically Baran and Jhalawar. Fenugreek is a specialty of Nagaur, particularly the fragrant variety. Cumin is the dominant spice of the western districts like Jalore and Barmer. Fennel is largely produced in Sirohi and Tonk. This distribution reflects the specific soil and moisture needs of each spice across Rajasthan’s different agricultural zones.
Q247. Consider the following statements regarding seed spices in Rajasthan:
I. Rajasthan holds a near monopoly in the production of Coriander and Fenugreek in India.
II. The Hadoti region is famous for its large-scale coriander cultivation.
III. Nagaur is internationally renowned for its fragrant ‘Pan Methi’ (Kasuri Methi).
IV. Seed spices are primarily Kharif crops requiring heavy monsoon rains.
V. The National Research Centre on Seed Spices is located at Tabiji, Ajmer.
Which of the above statement(s) is/are correct?
I. Rajasthan holds a near monopoly in the production of Coriander and Fenugreek in India.
II. The Hadoti region is famous for its large-scale coriander cultivation.
III. Nagaur is internationally renowned for its fragrant ‘Pan Methi’ (Kasuri Methi).
IV. Seed spices are primarily Kharif crops requiring heavy monsoon rains.
V. The National Research Centre on Seed Spices is located at Tabiji, Ajmer.
Which of the above statement(s) is/are correct?
Explanation
Rajasthan is a powerhouse in seed spice production, particularly coriander in Hadoti and the famous Pan Methi in Nagaur. The National Research Centre on Seed Spices in Ajmer provides critical scientific support. However, seed spices are primarily Rabi crops, not Kharif, as they require the cool and dry winter months rather than the heavy rains of the monsoon season.
Q248. Which geographic region of Rajasthan is overwhelmingly dominant in the cultivation of Coriander (Dhaniya)?
Explanation
The Hadoti plateau, comprising districts like Baran, Kota, and Jhalawar, is the most dominant region for coriander cultivation in Rajasthan.
Q249. Which of the following is not a prominent spice crop commercially grown in Rajasthan?
Explanation
Cardamom is a tropical plantation crop that requires high rainfall and specific high-altitude forest conditions, which are not present in Rajasthan. Conversely, Rajasthan is a leading producer of seed spices like Cumin and Fenugreek, and also grows large quantities of Garlic. The state’s dry climate is perfectly suited for these seed and bulb spices, but entirely unsuitable for cardamom cultivation.
Q250. Select the correct sequence of the following districts of Rajasthan in generally descending order of Cumin (Jeera) production:
Explanation
The western districts of Jalore, Barmer, and Jodhpur are the top producers of Cumin in Rajasthan. Jalore typically leads the production due to its favorable sandy loam soils and traditional expertise in cumin farming. These three districts form the core of the cumin-growing belt in the state, benefiting from the specific arid winter conditions required for this sensitive spice crop.Answer key for these questions

Key facts from Rajasthan Geography
- The RPSC syllabus lists Rajasthan’s location, extent and physiography, rivers and lakes, climate, vegetation, biodiversity, soils, agriculture, livestock, irrigation, population, urbanisation and tribes.
- Many questions ask for a number or a name: the area of the State, a district’s density, the length of a canal, the home district of a mine.
- Rajasthan is the biggest State of India by area, and several chapters test the contrast between the arid west and the humid south-east.
- Minerals, irrigation and wildlife are the chapters with the most name-based questions, so keep a list of districts and projects.
- Population questions use Census 2011 figures.
