UPSC CSE Prelims
Agriculture Previous Year Questions (PYQs)

Detailed Explanation:

Statement 1 — Incorrect.
RAD explicitly promotes Integrated Farming Systems (IFS), which combine multi-cropping, rotational cropping, horticulture, livestock, fishery, and agro-forestry. Monoculture is contrary to the scheme's philosophy.

Statement 2 — Incorrect.
RAD targets rainfed areas — regions without assured irrigation. Expanding rice cultivation in already-irrigated regions falls entirely outside its mandate.

Statement 3 — Correct.
The core objective of RAD is precisely to enhance productivity and build climate resilience through IFS, diversifying income sources to protect farmers from droughts, floods, and crop failure.

Key Point: RAD under NMSA is fundamentally about diversification and resilience in water-scarce, rain-dependent farming zones — the opposite of monoculture or irrigated expansion.

Answer: Option 2 — Only three

Simple Explanation:

Pair I — Correct. Cassava (tapioca/manioc) is a woody shrub, grown for its starchy roots.

Pair II — Correct. Ginger is a herb with a pseudostem (made of leaf sheaths, not a true stem); the part we eat is the rhizome.

Pair III — Correct. Malabar spinach is a soft, herbaceous climber — commonly grown as a leafy vegetable.

Pair IV — Incorrect. Mint is NOT a shrub — it's a perennial herb with soft stems that spread via stolons (runners).

Pair V — Incorrect. Papaya is NOT a woody shrub — it's actually a herbaceous tree ("giant herb") with a soft, hollow stem.

So 3 pairs (I, II, III) are correct; IV and V are wrong.

All three statements about niger (Guizotia abyssinica) are correct. The Government of India provides MSP for niger seeds as it is one of the 14 Kharif crops under the MSP scheme. Niger is indeed cultivated as a Kharif crop, primarily in hilly and tribal areas with poor soils. Niger seed oil is traditionally used for cooking by tribal communities in states like Odisha, Chhattisgarh, and Madhya Pradesh.

✅ Statement 1 – Correct: Niger seed is one of the 14 Kharif crops for which the Government of India announces Minimum Support Price (MSP) through the Commission for Agricultural Costs and Prices (CACP).

✅ Statement 2 – Correct: Niger is primarily cultivated as a Kharif (monsoon season) crop in India, especially in hilly and tribal regions with poor soil conditions.

✅ Statement 3 – Correct: Niger seed oil is traditionally used for cooking by tribal communities in various states, and also has other uses like lighting, lubrication, and in soap making.

📝 Short Notes: Niger Crop & MSP

• Niger (Guizotia abyssinica): A minor oilseed crop belonging to the Asteraceae family, also known as ramtil or black sesame in some regions.
• Cultivation Season: Primarily grown as a Kharif crop (sown in June-July, harvested in October-November).
• Growing Regions: Mainly cultivated in Odisha, Chhattisgarh, Madhya Pradesh, Maharashtra, Karnataka, and Jharkhand.
• Soil Requirements: Can grow in poor, marginal soils; suitable for hilly and tribal areas where other crops may not thrive.
• MSP Coverage: Part of 22 mandated crops (14 Kharif + 6 Rabi + 2 other commercial crops) for which Government announces MSP.

Detailed Explanation:

Answer: Option 2 — Many marginal farmers in an area organize themselves into groups and synchronize and harmonize selected agricultural operations

The 'Small Farmer Large Field' (SFLF) model is a participatory collective action approach where small and marginal farmers with contiguous land holdings voluntarily form groups to collectively perform key agricultural operations like land preparation, sowing, irrigation, and harvesting. This farmer-led model helps overcome the limitations of fragmented land holdings by achieving economies of scale in input procurement and output marketing, while individual farmers retain ownership of their land. The model was adapted from Vietnam's successful 'Large Field' approach and has been piloted in states like Odisha to address challenges faced by marginal farmers.

Why other options are incorrect:
• Option 1 describes a refugee resettlement and rehabilitation program with collective farming, not the SFLF model.
• Option 3 describes corporate farming where farmers surrender land to a corporate body for a fixed term—this involves loss of operational control, unlike SFLF.
• Option 4 describes contract farming where a company provides inputs and technical support to farmers who produce specific crops for the company's requirements—this is company-driven, whereas SFLF is farmer-driven and focuses on collective operations rather than specific crop contracts.

📝 Short Notes: Small Farmer Large Field (SFLF) Model

• Origin: Adapted from the 'Large Field' model successfully implemented in Vietnam
• Objective: To help small and marginal farmers overcome constraints of land fragmentation, low bargaining power, and lack of economies of scale
• Key Feature: Farmers with contiguous land holdings voluntarily organize into groups to synchronize selected agricultural operations
• Ownership: Individual farmers retain complete ownership of their land—only operations are collectively performed
• Operations Synchronized: Land preparation, sowing, irrigation, plant protection, harvesting, and marketing
• Benefits: Economies of scale in input purchase, better bargaining power, reduced cost of cultivation, improved productivity, and better market access
• Implementation in India: Piloted in Odisha and other states as part of initiatives to support marginal farmers
• Nature: Farmer-led participatory model, not corporate-driven or contract farming

Detailed Explanation:
