Agriculture

Consider the following statements:

• 1. India has more arable area than China.
• 2. The proportion of irrigated area is more in India as compared to China.
• 3. The average productivity per hectare in Indian agriculture is higher than that in China.

How many of the above statements are correct?

[amp_mcq option1=”Only one” option2=”Only two” option3=”All three” option4=”None” correct=”option1″]

Statement 1 is correct: India has a larger area of arable land (land under temporary crops, meadows, pastures) compared to China. Estimates vary, but India’s arable land is typically cited as around 155-160 million hectares, while China’s is around 120-130 million hectares.
Statement 2 is incorrect: China has a higher proportion of irrigated area relative to its cultivated land compared to India. China has made massive investments in irrigation infrastructure.
Statement 3 is incorrect: China generally has higher average agricultural productivity per hectare for most major crops compared to India due to greater mechanization, input use efficiency, and technological adoption.

– India possesses more available land suitable for cultivation.
– China has a higher reliance on and proportion of irrigated farming.
– China generally achieves higher yields per unit area in agriculture.

Despite having more arable land, India’s large population size results in lower per capita availability of cultivated land compared to China. Both countries face challenges related to water management and sustainable agricultural practices.

Among the following, which one is the least water-efficient crop?

[amp_mcq option1=”Sugarcane” option2=”Sunflower” option3=”Pearl millet” option4=”Red gram” correct=”option1″]

Among the given options, sugarcane is generally considered the most water-intensive crop. While the water requirement varies depending on the region, soil type, and climate, sugarcane needs a large amount of water throughout its long growing season compared to the other crops listed. Pearl millet (Bajra) and Red gram (Arhar) are typically grown as rainfed crops or require less water, especially Pearl millet which is known for its drought tolerance. Sunflower also requires less water than sugarcane. Therefore, sugarcane is the least water-efficient crop among the options.

– Water efficiency of crops refers to the amount of yield produced per unit of water consumed.
– Sugarcane is a long-duration crop with high water requirements.
– Pearl millet and Red gram are relatively drought-tolerant crops.

Water efficiency can also be measured by the yield per unit of water transpired (WUE – Water Use Efficiency) or applied (IRWUE – Irrigation Water Use Efficiency). Crops like sugarcane, rice, and cotton are known for high water consumption. Promoting water-efficient crops and practices is crucial for sustainable agriculture, especially in water-scarce regions.

With reference to the current trends in the cultivation of sugarcane in India, consider the following statements:

• A substantial saving in seed material is made when ‘bud chip settlings’ are raised in a nursery and transplanted in the main field.
• When direct planting of setts is done, the germination percentage is better with single-budded setts as compared to setts with many buds.
• If bad weather conditions prevail when setts are directly planted, single-budded setts have better survival as compared to large setts.
• Sugarcane can be cultivated using settlings prepared from tissue culture.

Which of the statements given above is/are correct ?

[amp_mcq option1=”1 and 2 only” option2=”3 only” option3=”1 and 4 only” option4=”2, 3 and 4 only” correct=”option3″]

Statements 1 and 4 are correct. Statements 2 and 3 are incorrect.

Statement 1 is correct because bud chip settlings (using small cane pieces with just one bud grown in a nursery) significantly reduce the amount of seed cane required compared to traditional methods. Statement 4 is correct as tissue culture is a viable method for producing disease-free sugarcane planting material. Statement 2 is incorrect; traditional direct planting uses multi-bud setts (typically 2-3 buds) for better germination and survival compared to single-budded setts. Statement 3 is incorrect; larger setts with more buds and reserves are generally more resilient to adverse weather conditions than smaller single-budded setts when planted directly.

Modern techniques like bud chip technology and tissue culture propagation aim to improve the efficiency and health of sugarcane cultivation. They help in conserving planting material, reducing disease spread, and achieving better crop stands.

Consider the following pairs:

Region	Well-known for the production of
1. Kinnaur	Areca nut
2. Mewat	Mango
3. Coromandel	Soya bean

Which of the above pairs is/are correctly matched?

[amp_mcq option1=”1 and 2 only” option2=”3 only” option3=”1, 2 and 3″ option4=”None” correct=”option4″]

The correct answer is D) None. Let’s examine each pair:
1. Kinnaur: Kinnaur district in Himachal Pradesh is famous for apples, grapes, and apricots. Areca nut (supari) is predominantly grown in coastal regions of South India and parts of Northeast India. This pair is incorrectly matched.
2. Mewat: Mewat region spans parts of Haryana and Rajasthan and is primarily an agricultural area known for crops like wheat, barley, mustard, and also dairy farming. It is not particularly known for large-scale mango production compared to traditional mango-growing belts in India. This pair is incorrectly matched.
3. Coromandel: The Coromandel Coast is the southeastern coast of India. While agriculture is practiced, it is not primarily known for large-scale soya bean production. Soya bean cultivation is concentrated in states like Madhya Pradesh (often called the “Soya State”), Maharashtra, and Rajasthan. This pair is incorrectly matched.

Geographical regions are often known for specific agricultural products based on climate, soil conditions, and traditional practices. Knowing the primary produce of different regions in India is relevant for geography and economics.

Areca nut cultivation is significant in states like Karnataka, Kerala, Assam, and Meghalaya. Major mango-producing states include Uttar Pradesh, Andhra Pradesh, Telangana, Karnataka, Bihar, and Maharashtra. Madhya Pradesh is the largest producer of soya bean in India.

Consider the following crops:

• 1. Cotton
• 2. Groundnut
• 3. Rice
• 4. Wheat

Which of these are Kharif crops?

[amp_mcq option1=”1 and 4″ option2=”2 and 3 only” option3=”1, 2 and 3″ option4=”2, 3 and 4″ correct=”option3″]

The correct answer is C) 1, 2 and 3. Cotton, Groundnut, and Rice are all Kharif crops.

Kharif crops, also known as monsoon crops, are sown at the beginning of the southwest monsoon season (typically June-July) and harvested at the end of the monsoon season (typically September-October). Rice, cotton, and groundnut are prominent examples of Kharif crops in India. Wheat is a Rabi crop, sown in winter and harvested in spring/summer.

Other examples of Kharif crops include Maize, Jowar, Bajra, Tur (Arhar), Moong, Urad, Jute, Soybean, etc. Rabi crops are sown after the monsoon (October-December) and harvested in spring (April-May); examples include Wheat, Barley, Gram, Rapeseed and Mustard, Lentil, etc. There is also a short season called Zaid during summer for crops like watermelon, cucumber, and vegetables.
