Q562. The primary advantage of integrating Medicinal and Aromatic Plants into traditional farming systems in Rajasthan is:
Explanation
Integrating Medicinal and Aromatic Plants into traditional farming systems offers significant advantages for Rajasthan’s farmers. These plants often provide higher economic returns compared to traditional food grains. Furthermore, many medicinal species are naturally avoided by stray cattle and wild grazing animals due to their bitter taste or chemical properties. This reduces the risk of crop damage and lowers protection costs.
Q563. Rajasthan is a leading producer of seed spices in India. Which region of Rajasthan is prominently known for spice cultivation?
Explanation
Rajasthan is a major hub for seed spice cultivation in India, with production concentrated in specific regions. The Hadoti region (southeastern Rajasthan) and the Jodhpur-Nagaur belt in the west are the primary areas for spice farming. These regions provide the necessary climatic conditions for crops like cumin, coriander, and fenugreek. Spice cultivation has become a backbone of the regional economy.
Q564. Which of the following seed spices constitutes a major agricultural export from Rajasthan?
Explanation
Cumin, or Jeera, is one of the most important agricultural exports from Rajasthan. The state accounts for a massive share of the national cumin production. This spice is highly valued in international markets for its quality and essential oil content. Western districts like Jalore and Barmer are famous for their high-quality cumin. Its export contributes significantly to foreign exchange earnings.
Q565. Identify the correct statement regarding Cumin (Jeera) cultivation in Rajasthan.
Explanation
Cumin is a delicate Rabi season crop in Rajasthan that requires careful management. It is highly sensitive to extreme cold and frost, which can severely damage the flowering stage. Additionally, the crop is prone to diseases like Alternaria blight and wilt, especially during cloudy weather. Successful cumin cultivation requires precise weather conditions and timely plant protection measures for a harvest.
Q566. The National Research Centre on Seed Spices (NRCSS) is located in which district of Rajasthan?
Explanation
The National Research Centre on Seed Spices is located at Tabiji in the Ajmer district. This premier institute focuses on research and development related to various seed spices like cumin, coriander, and fennel. It works on developing high-yielding varieties and standardized production technologies for farmers. The center’s location in Ajmer is strategic, given the district’s proximity to major spice-growing regions.
Q567. Match the items in List I with those in List II and select the correct answer using the codes given below:
| Spice | Prominent Cultivating District/Region |
|---|---|
| A. Cumin (Jeera) | i. Jalore and Barmer |
| B. Coriander (Dhaniya) | ii. Baran and Kota |
| C. Fenugreek (Methi) | iii. Nagaur |
| D. Fennel (Saunf) | iv. Sirohi and Tonk |
Explanation
Different regions of Rajasthan are specialized in the production of various seed spices. Cumin is a major crop in the Jalore and Barmer districts, while Coriander is predominantly grown in the Hadoti region’s Baran and Kota districts. Nagaur is famous for its high-quality Fenugreek, and Fennel is commonly cultivated in the Sirohi and Tonk areas. This regional specialization is traditional.
Q568. Coriander (Dhaniya) cultivation is predominantly concentrated in the southeastern districts of Rajasthan. What type of soil in this region supports its cultivation?
Explanation
Coriander cultivation in southeastern Rajasthan is supported by the presence of heavy black soils, scientifically known as Vertisols. These soils have high water-holding capacity and are rich in nutrients, making them ideal for the Hadoti region’s agricultural pattern. The combination of fertile soils and favorable winter climate allows for large-scale commercial production. Rajasthan remains a leading producer of coriander.
Q569. Which weed is a major biological constraint and parasitic threat to cumin cultivation in Rajasthan?
Explanation
Plantago, locally known as Zeeri, is a major weed that poses a significant biological constraint to cumin cultivation in Rajasthan. Its seeds are very similar in appearance to cumin, making it difficult to separate during and after harvest. Zeeri competes with the main crop for nutrients and moisture, leading to reduced yields and quality. Managing this weed is a challenge.
Q570. What is the economic significance of cultivating seed spices like cumin, coriander, and fenugreek in Rajasthan?
Explanation
Cultivating seed spices like cumin and coriander is economically significant for Rajasthan because they are short-duration cash crops. They require relatively less water compared to traditional Rabi crops like wheat, making them ideal for the state’s water-scarce environment. These spices fetch high prices in international markets, providing farmers with substantial returns in a short period. They drive rural prosperity.Answer key for these questions
