• Storage of agricultural produce is part of the tertiary sector because it involves services like storing, moving, and distributing goods. Therefore, Pair 1 is not correct.
• A dairy farm belongs to the primary sector, which includes activities related to farming and raising animals. Thus, Pair 2 is correct.
• Mineral exploration is also in the primary sector because it is about getting natural resources from the earth. So, Pair 3 is incorrect.
• Weaving cloth falls under the secondary sector, which involves making products and industrial work. Hence, Pair 4 is correct.

Correct Answer is Option (b)

•  A farmer's plough is seen as fixed capital because it is a long-lasting asset that the farmer uses over many planting seasons. Therefore, Pair 1 is incorrect. 
•  A computer is classified as fixed capital as it is a durable item used in the production process for several years. Thus, Pair 2 is correct. 
• Yarn that a weaver uses is regarded as working capital because it gets used up during the production of fabrics. Hence, Pair 3 is incorrect. 
• Petrol is considered working capital since it is consumed during the production process and must be regularly replaced. Therefore, Pair 4 is correct. 

Correct Answer is Option (d)

• The Digital India Land Records Modernization Programme (formerly known as the National Land Record Modernization Programme) was updated and changed into a Central Sector Scheme starting from April 1, 2016, with full funding provided by the Central Government. Therefore, statement 1 is correct.
• Significant progress has been made under the DILRMP Programme.
• Regarding key components, the Computerization of Land Records has achieved completion of 95.08 percent of the Records of Rights (RoR), with 625,062 villages out of a total of 657,396 villages in the country having been completed. Thus, statement 2 is correct.
• Additionally, 68.02 percent of the Cadastral Maps have been digitized, with 24,957,221 maps out of a total of 36,692,728 maps completed.
• To tackle the issue of language barriers in land governance, the Government, with the technical assistance of the Centre for Development of Advanced Computing (C-DAC) in Pune, has launched a project to convert the Records of Rights available in local languages into any of the 22 languages listed in Schedule VIII of the Constitution. Therefore, statement 3 is correct.

Correct Answer is Option (c)

Niger Seeds (Guizotia Abyssinica): 

• Niger seeds are tiny seeds that come from the Niger plant and are recognized for their various uses in cooking and traditional medicine.

Minimum Support Price (MSP): 

• The Government of India sets a Minimum Support Price for niger seeds as part of its MSP program, which covers 14 Kharif crops.
• This oilseed, which is not widely known, has one of the highest MSPs, determined by its production costs and market demand.
• Therefore, both statements regarding MSP are accurate.

Tribal Use of Niger Seed Oil: 

• In some tribal communities in India, niger seed oil is often used for cooking, especially because it has a high smoke point, making it great for frying and other cooking methods.
• This means that the third statement is also correct.

Correct Answer is Option(a)

•  The real sector of the economy includes activities that create goods and services. This includes sectors like agriculture, manufacturing, and various services that produce physical items. 
•  This sector is different from the financial sector, which is focused on financial transactions and services. 
•  The real sector performs better when there is a strong and healthy financial system. Thus, improving the financial sector helps the real sector to grow. 
• Important statistics in the real sector include: 
  • Production data from agriculture and industry
  • Gross Domestic Product (GDP)
  • Private investment and consumption
  • Wholesale and consumer price indices (inflation)
  • Employment rates
•  The real sector is focused on production, while the nominal economy relates to financial activities. 
• Examples of real sector activities: 
  • Farmers harvesting their crops
  • Textile mills turning raw cotton into fabric
•  Therefore, the first two statements about the real sector are correct. 
•  While financial activities support the real sector, they do not contribute significantly to production, except for the income they generate. 
• Examples of financial sector activities: 
  • A commercial bank lending money to a trading company
  • A corporate body issuing Rupee Denominated Bonds overseas
•  Thus, the last two statements about the real sector are not correct. 

Correct Answer is Option (b)

• Statement 1 is correct: Permaculture is a totally integrated design system that’s modelled on nature. Permaculture farming promotes multicropping and integrated farming systems. Agroforestry is its example.  
• Chemical farming is more suitable for monoculture cropping due to use of crop specific inputs like irrigation, chemical fertiliser and harvesting methods.  
• Statement 2 is correct:Chemical fertilizers will make the soil less fertile over time, which can lead to serious problems like soil salinisation. But such problems are not seen in permaculture farming as it relies on organic fertilizers.  
• Statement 3 is incorrect:Chemical farming is based on intense use of inputs like Chemical fertilizers and irrigation that make the soil less fertile over time, thus restricting its practise in semi-arid region. Thus, conventional farming is not suitable for semi-arid regions.  
• The concept of permaculture involves well-designed systems don’t produce waste and permaculture tries to mimic well-designed systems. Thus, permaculture tries to take into account the local conditions like arid climate. This helps in developing a suitable system to ensure sustainable production. 
• Statement 4 is correct:Mulching is an important component of Permaculture systems for promoting maximum efficiency.  
• Chemical farming does not consider it as essential, so farmers in general do not use mulching. 

Correct Answer is Option (b)

• Statement 1 is incorrect: More than 80 percent of palm oil is grown in Southeast Asia, with Indonesia and Malaysia leading the world in production of the commodity. Oil palms were introduced to Malaysia and Indonesia in the mid-20th century from Africa, and large scale production followed. The growth has been rapid and widespread, and the natural forest and all that live in it face a dire future.
• Statement 2 is correct:Palm oil and its derivatives are present in at least 70% of cosmetic products, according to Croda, a global specialty ingredients supplier to the beauty and personal care industry.
• This goes to show that palm-derived ingredients are preferred by the manufacturers for their functional benefits.
• Statement 3 is correct:Generally, RBD palm oil is used to produce biodiesel due to the low FFA content (0.1-0.5%) and thus minimize the impact of saponification reaction. Darnoko and Cheryan (2000) studied the transesterification of RBD palm oil with methanol catalyzed by KOH.

Correct Answer is Option (d)

• Biochar is a stable, carbon-rich form of charcoal that is applied to the soil. 
• biochars from manures and food wastes recorded higher nitrogen and phosphorus levels. So #2 is right. 
• Some biochars can increase soil fertility, water holding capacity, and crop productivity. So #3 is right 
• There is only one option where #2 and #3 are together so the answer is “d”.

Correct Answer is Option (a)

• Sugarcane requires an annual rainfall of between 75cm. and 100cm. Irrigation is required in regions of low rainfall. So, #C was eliminated. 
• Cotton requires high temperature, light rainfall or irrigation, 210 frost-free days. 
• Jute: require es high temperature, heavy rainfall, and humid climate 
• Tea: requires a cool climate and well-distributed high rainfall throughout the year 
• Cotton: Cotton requires high temperature, light rainfall, 210 frost-free days. 
• Considering these descriptions, cotton seems to be the better choice among the given options.

Correct Answer is Option (d)

• Open burning of crop residues in the agricultural fields has become an environmental concern in India, particularly during the paddy harvesting season. ....The Union government is providing subsidies for Happy Seeders, Zero Till Seed Drill, etc. which can help to plant the seeds for the next crop without burning the previous crop. So, #1 is correct. Ref: Economic Survey 2019-20 Volume 2 page 186-189. 
• In the zero tillage, We are not disturbing the soil and we are not burning the previous crop Residue so that way, it could help in Carbon sequestration. So, #3 should be correct.

Correct Answer is Option (c)

NCERT vocational class 11 floriculture ist book page 84:  When an element forms precipitate with another substance commonly found in the irrigation water, it is not advisable to use this method. Phosphorus and anhydrous ammonia may form a precipitate in water with high calcium and magnesium content. So they are not used in fertigation. So 2nd statement is wrong by elimination we arrived at the answer “c”.

Correct Answer is Option (c)

Kurukshetra February 2018 Issue on Agriculture, page 43 has given three key features of conservation agriculture viz: i. minimum soil disturbance by adopting no-tillage or minimum tillage and reduced traffic for agricultural operations. So, #2 is right. This eliminates Option (a) ii. maximum soil cover by leaving crop residues on the soil surface. So, #4 is right. This eliminates Option (d) iii. adopt spatial and temporal crop sequencing/crop rotation. So, #5 is verbatim right. Hence final answer (c)

Correct Answer is Option (d)
Since UPSC has combined the preliminary exam of civil services and forest services, so few such odd questions are expected. There is no need to lose sleep if you can't solve it. But let's do it: NCERT Class 12 Biology Chapter 6: "Molecular Basis of Inheritance". It explains the benefits of human genome sequencing that- "It is the sequence of bases in DNA that determines the genetic information of a given organism. So, learning about the DNA sequences can lead to an understanding of their natural capabilities that can be applied toward solving challenges in health care, agriculture, energy production, environmental remediation." So on that logic, statements 1 and 3 should be possible, and if 1 and 3 are possible then statement 2 ought to be possible as well! So answer (d) all three statements are correct. Searching academic papers on Google Scholar engineer confirms that (d) is the answer.

Correct Answer is Option (c)
According to the Kurukshetra Magazine, November 2017 special issue on irrigation: Tillage exposes the soil to drying, conversely, reductions in tillage help conserve soil water. So #1 is right. The retention of crop residues helps in reducing water loss from the soil to the air and cools the soil. So, #3 is right. According to some random research papers & Google books, even gypsum application helps in water conservation so experts were divided between Option (c) or (d). But in the official answer key, UPSC has kept (c) as the correct answer.

Correct Answer is Option (c)
Both statements are correct as per Government notification.

Correct Answer is Option (b)
A soil health card provides information about 12 soil parameters, so farmer can use appropriate fertilizers. hence only 3 is the correct statement. Statement 1 and 2 are irrelevant.

Correct Answer is Option (c)
(i)This initiative aims to demonstrate the improved production and post-harvest technologies in an integrated manner to catalyze increased production of millets in the country. The scheme, through processing and value addition techniques, is expected to generate consumer demand for millet-based food products. Poor, small, marginal, and tribal farmers have a larger stake in this scheme.
(ii) 1st and 2nd statements are right. The policy aims to give free kits but “wanting to shift commercial crop farmers to millet” doesn’t fit logic. There is no such mention in the scheme, nor any talk about giving micro-irrigation equipment. Hence 3rd statement is wrong.

Correct Answer is Option (b)
(i)In order to safeguard and support the world’s agricultural heritage systems, in 2002 FAO started an initiative for the dynamic conservation of Globally Important Agricultural Heritage Systems (GIAHS). The GIAHS Initiative promotes public understanding, awareness, national and international recognition of Agricultural Heritage systems. It aims to identify and ensure global recognition of the importance of unique traditional agricultural systems for food security and sustainable development. The GIAHS initiative explicitly recognizes that change in “traditional” political, social, and economic processes is inevitable; they cannot be frozen or re-created.
(ii) There is no provision to give Geographical indication to “ALL” varieties. Hence statement 3 is wrong. By elimination method, we are left with answer (b) only 2.

Correct Answer is Option (c)
'Agreement on Agriculture', 'Agr eement on the Application of Sanitary and Phytosanitary Measures' and 'Peace Clause' are related to World Trade Organisation.

Correct Answer is Option (b)
Agricultural Produce Market Committee Acts of respective states are responsible for markets in agricultural products.

Correct Answer is Option (c)
Excessive/inappropriate use of nitrogenous fertilizers increases the acidity of soil and the Leaching of nitrate into the ground water.

Correct Answer is Option (b)
The seed village concept is to promote the quality seed production of foundation and certified seed classes. The area which is suitable for raising a particular crop will be selected and raised with a single variety of a kind. A suitable area for seed production will be identified by the Scientists. The foundation/ certified seeds or University labeled seeds will be supplied by the University through Krishi Vigyan Kendras (KVKs) and Research Stations at 50% subsidy cost to the identified farmers in the area. The farmers will use these quality seeds and take up their own seed production in a small area (1 acre) for their own use. The crops are Rice, Pulses, and Oilseeds.

Correct Answer is Option (b)
Capital-augmenting technological progress results in the more productive use of existing capital goods; for example, the substitution of steel from wooden ploughs in agricultural production.

Correct Answer is Option (c)
Vegetative reproduction is a form of asexual reproduction in plants. It is a process by which new organisms arise without the production of seeds. It helps in the development of clones. Vegetative propagation involves only mitosis, this ensures that the genetic information in the DNA of vegetative progeny (child) is the same as in the mother plant and can be practiced throughout the year. However, it does not helps in the elimination of viruses. A plant once systematically infected with a virus usually remains infected for its lifetime. Thus any vegetative parts taken for propagation remain infected.

Correct Answer is Option (b)
Guar gum is used in hydraulic fracturing technology during shale gas extraction.

Correct Answer is Option (c)
Integrated Watershed Management Programme (IWMP) was launched during 2009-10. It aims at Prevention of soil runoff, Rainwater harvesting, and recharge of groundwater table, and Regeneration of natural vegetation.

Correct Answer is Option (d)
The draught-prone area program is by the ministry of Rural development to minimize the adverse effects of drought on the production of crops and livestock and productivity of land, water, and human resources. The desert development program is also by the ministry of Rural development to minimize the adverse effect of drought and control desertification. National Watershed Development Project for Rainfed Areas is by the ministry of agriculture.

Correct Answer is Option (b)
NPK (fertilizers) can be applied at the rate of 112 kg, 25 kg, and 48 kg per acre, respectively through inorganic or organic methods. Hence statement #3 is wrong, this eliminates (a), (c), and (d). therefore, answer (b) 1,2,4 only.

Correct Answer is Option (d)
All three statements are correct as Maize can be used for the production of starch. Oil extracted from maize can be a feedstock for biodiesel. Alcoholic beverages can be produced by using maize.

Correct Answer is Option (d)
Cytoplasmic male sterility and gene silencing are used for the creation of transgenic crops. Grafting and budding in fruit plants are not used for transgenic crop production but used during regular horticulture practices.

Correct Answer is Option (d)
Kinnaur (Himachal) is famous for apples. Areca nut is mostly confined to Karnataka, Kerala, and Assam. Mewat in Haryana is not famous for mango. UP is famous for mango. Similarly, the coromandel coast is not famous for soya beans. The top two producers of soya are Madhya Pradesh and Maharashtra which are outside the coromandel coast. Therefore, (d) is the correct option.
