Q232. Arrange the following districts of Rajasthan in descending order based on their general contribution to groundnut production in recent years:
I. Bikaner
II. Jodhpur
III. Jaipur
IV. Dungarpur
Select the correct order from the options given below:
I. Bikaner
II. Jodhpur
III. Jaipur
IV. Dungarpur
Select the correct order from the options given below:
Explanation
Bikaner has emerged as the leading producer of groundnut in Rajasthan, particularly in the Lunkaransar area. It is followed by Jodhpur and Jaipur, which also have significant areas under cultivation. Dungarpur in the south produces groundnut but at a lower total volume compared to the major northern and central hubs. This ranking reflects the recent expansion of groundnut farming.
Q233. Which statement is correct regarding the distribution of Groundnut in southern Rajasthan?
Explanation
In southern Rajasthan, districts like Chittorgarh and Bhilwara are notable for groundnut cultivation. Farmers in these areas utilize the local red and black soils, which provide suitable conditions for the crop during the Kharif season. Unlike the irrigated northern tracts, groundnut here relies more on seasonal rainfall, though it remains a significant contributor to the regional agricultural output.
Q234. Identify the odd one out with respect to major pests and diseases that affect groundnut cultivation in Rajasthan.
Explanation
The pink bollworm is a major pest specifically associated with cotton crops, not groundnut. Groundnut cultivation in Rajasthan is frequently threatened by the white grub, tikka disease, and collar rot. Identifying the correct pests is crucial for farmers to implement effective crop protection strategies and prevent significant yield losses in the state’s diverse oilseed and fiber crop sectors.
Q235. Which place in Rajasthan is popularly known as the ‘Rajkot of Rajasthan’ due to its high production and excellent quality of groundnut?
Explanation
Lunkaransar, located in the Bikaner district, is famously called the ‘Rajkot of Rajasthan’. This title is earned due to its exceptionally high production and the superior quality of groundnut grown in the region. The development of irrigation facilities in this arid belt has transformed it into a major commercial hub for groundnut, mimicking the importance of Rajkot in Gujarat’s agriculture.
Q236. Why is loose, friable, and well-drained sandy loam soil essential for successful groundnut cultivation?
Explanation
Loose and friable sandy loam soil is essential for groundnuts because the plant undergoes a process called ‘pegging’. After pollination, the flower stalks must grow downward and penetrate the soil to develop pods underground. Hard or compacted soil would prevent this penetration, leading to poor pod formation. Well-drained soil also prevents the rotting of the developing pods in the ground.
Q237. Match the Cotton Varieties in List I with their Prominent Regions in Rajasthan in List II:
| Cotton Variety/Type | Prominent Region |
|---|---|
| A. American Cotton (Narma) | i. Jhalawar, Kota, Banswara |
| B. Malvi Cotton | ii. Ganganagar and Hanumangarh |
| C. Desi Cotton | iii. Udaipur and Chittorgarh |
| D. Bikaneri Narma | iv. Bikaner and surrounding irrigated tracts |
Explanation
American Cotton, often called Narma, is the mainstay of Ganganagar and Hanumangarh. Malvi Cotton is grown in the south-eastern districts like Jhalawar and Kota. Desi Cotton is common in Udaipur and Chittorgarh. Bikaneri Narma is specifically cultivated in the irrigated tracts of Bikaner. These varieties are selected based on the regional availability of water and specific soil types across Rajasthan.
Q238. Consider the following statements regarding American Cotton cultivation in the Ganganagar- Hanumangarh belt:
I. It is predominantly a rainfed crop requiring no artificial irrigation.
II. It possesses longer staples compared to the indigenous Desi cotton varieties.
III. The availability of canal water (like the Indira Gandhi Canal and Gang Canal) has made this belt the top producer in the state.
Which of the above statement(s) is/are correct?
I. It is predominantly a rainfed crop requiring no artificial irrigation.
II. It possesses longer staples compared to the indigenous Desi cotton varieties.
III. The availability of canal water (like the Indira Gandhi Canal and Gang Canal) has made this belt the top producer in the state.
Which of the above statement(s) is/are correct?
Explanation
American Cotton in the Ganganagar- Hanumangarh belt is highly dependent on canal irrigation and is not a rainfed crop. It is preferred because it possesses longer fibers or staples than indigenous varieties. The availability of water from the Indira Gandhi and Gang Canals has successfully transformed this northern region into the state’s leading producer of this high-value commercial fiber crop.
Q239. Consider the following statements and select the correct option:
Statement I: The Pink Bollworm is a major threat to cotton cultivation in northern Rajasthan.
Statement II: The adoption of Bt Cotton has permanently eradicated all pest issues in the state.
Statement I: The Pink Bollworm is a major threat to cotton cultivation in northern Rajasthan.
Statement II: The adoption of Bt Cotton has permanently eradicated all pest issues in the state.
Explanation
The Pink Bollworm remains a major biological threat to cotton farming in northern Rajasthan, causing significant damage to the bolls. While Bt Cotton was introduced to resist certain pests, it has not permanently eradicated all issues, as pests can develop resistance over time and other non-target pests may emerge. Constant monitoring and integrated pest management are still required for successful cultivation.
Q240. The following question consists of two statements, one labeled as Assertion (A) and the other as Reason (R). Select the correct answer using the codes given below:
Assertion (A): Sri Ganganagar and Hanumangarh are the leading districts in cotton production in Rajasthan.
Reason (R): These districts are characterized by the availability of assured canal irrigation networks and fertile alluvial soils.
Assertion (A): Sri Ganganagar and Hanumangarh are the leading districts in cotton production in Rajasthan.
Reason (R): These districts are characterized by the availability of assured canal irrigation networks and fertile alluvial soils.
Explanation
Sri Ganganagar and Hanumangarh lead Rajasthan in cotton production because they possess the two most critical requirements: fertile alluvial soil and an assured supply of canal irrigation. The dry climate of the north is also conducive to cotton growth provided water is available. This synergy between infrastructure and natural resources explains the regional concentration of the state’s fiber production.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.
