Q252. Identify the odd one out among the major diseases affecting Cumin (Jeera) in western Rajasthan.
Explanation
Red Rot is a major disease specifically affecting sugarcane, characterized by the reddening of the internal stalk tissues. In contrast, Cumin in western Rajasthan is frequently plagued by Blight, Powdery Mildew, and Wilt. These fungal diseases are the primary threats to cumin yields and require careful management and chemical treatment to prevent widespread loss of the valuable spice harvest.
Q253. What is the most appropriate reason for the concentration of Cumin (Jeera) cultivation in districts like Jalore, Barmer, and Jodhpur?
Explanation
Cumin is concentrated in Jalore, Barmer and Jodhpur because the cool, dry winters and light sandy-loam soils of this region suit it.
Q254. Which of the following agricultural practices is deemed critical during the harvesting stage of Cumin (Jeera) to maintain its export quality?
Explanation
Harvesting cumin requires precise timing to maintain export quality. Farmers must uproot or cut the plants as soon as they turn yellowish-brown to prevent the ‘shattering’ of the small, dry seeds. If left too long in the field, the seeds will fall off easily, leading to significant yield loss. Proper drying and careful threshing are also critical to preserve the aroma.
Q255. Match the Horticultural Crops in List I with their Leading Producing Districts in Rajasthan in List II:
| Horticultural Crop/Fruit | Leading Producing District |
|---|---|
| A. Kinnow (Mandarin) | i. Sawai Madhopur |
| B. Orange (Santra) | ii. Jhalawar |
| C. Guava (Amrood) | iii. Barmer / Jalore |
| D. Pomegranate (Anar) | iv. Ganganagar / Hanumangarh |
Explanation
Kinnow is the pride of Ganganagar and Hanumangarh. Oranges are the staple of Jhalawar, known as the state’s citrus hub. Guava production is highly concentrated in Sawai Madhopur, while Pomegranate cultivation has seen rapid growth in the arid districts of Barmer and Jalore through drip irrigation. This match illustrates the diverse fruit-growing regions of Rajasthan.
Q256. What is the primary cause of increasing soil salinity in the Indira Gandhi Canal command area?
Explanation
In the Indira Gandhi Canal command area, the introduction of large volumes of water into a desert environment has caused the water table to rise. As this water moves upward through capillary action in the soil, it carries dissolved underground salts to the surface. When the water evaporates, these salts are left behind, gradually increasing soil salinity and creating the ‘Sem’ problem.
Q257. Match the Agricultural Challenges in List I with the Regions most severely affected in Rajasthan in List II:
| Agricultural Challenge | Region |
|---|---|
| A. Waterlogging (Sem) | i. Nagaur - Ajmer belt (Banka Patti) |
| B. Severe Wind Erosion | ii. Hanumangarh - Ganganagar |
| C. Gully Erosion (Ravines) | iii. Jaisalmer - Barmer |
| D. Fluoride contamination in groundwater | iv. Dholpur - Sawai Madhopur |
Explanation
Waterlogging is a major issue in the irrigated north. Wind erosion is most severe in the arid western districts of Jaisalmer and Barmer.
Q258. Consider the following statements regarding the ‘Mukhyamantri Krishak Sathi Yojana’ in Rajasthan:
I. It aims to provide financial assistance to farmers and agricultural laborers in case of death or disability due to accidents during agricultural work.
II. It promotes the distribution of free micro-irrigation equipment to all farmers.
III. The scheme covers accidents caused by agricultural machinery and electrocution.
IV. The financial assistance amount provided under the scheme can range up to 2 Lakh for accidental death.
V. It was launched exclusively for farmers growing commercial cash crops.
Which of the above statement(s) is/are correct?
I. It aims to provide financial assistance to farmers and agricultural laborers in case of death or disability due to accidents during agricultural work.
II. It promotes the distribution of free micro-irrigation equipment to all farmers.
III. The scheme covers accidents caused by agricultural machinery and electrocution.
IV. The financial assistance amount provided under the scheme can range up to 2 Lakh for accidental death.
V. It was launched exclusively for farmers growing commercial cash crops.
Which of the above statement(s) is/are correct?
Explanation
The Mukhyamantri Krishak Sathi Yojana provides social security to farmers and laborers. It offers financial assistance of up to 2 Lakh in case of accidental death or disability during farm work, including machinery accidents or electrocution. It is not limited to commercial crop farmers and does not primarily focus on distributing free micro-irrigation equipment, though other state schemes may cover those needs.
Q259. The ‘Rajasthan Millets Mission’ was launched by the state government with an initial budgetary allocation to promote the cultivation and processing of millets. In which financial year budget was it prominently announced?
Explanation
The Rajasthan Millets Mission was prominently announced in the state budget for the financial year 2022-23. The mission aims to promote the production, consumption, and value addition of millets like Bajra and Jowar. By establishing processing units and providing incentives to farmers, the state seeks to leverage its position as a leading millet producer to enhance nutritional security and farmers’ income.
Q260. Which statement is correct regarding the implementation of the PM-KUSUM scheme in Rajasthan?
Explanation
Rajasthan has been a leader in implementing the PM-KUSUM scheme, which focuses on solarizing the agricultural sector. The first solar power plant under Component-A of this scheme was commissioned at Bhaloji village in Jaipur. This initiative allows farmers to generate solar energy on barren land, providing them with a steady source of income while promoting the use of clean energy for irrigation.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.
