Agricultural Revolutions — Set 12

Correct Answer: B. Nanotechnology-based liquid urea developed by IFFCO that can replace bag urea for nitrogen supply

Nano urea is a liquid nitrogen fertilizer developed by IFFCO using nanotechnology, where urea is in nanoparticle form that can be sprayed directly on leaves. A 500 ml bottle of nano urea can replace one bag (50 kg) of conventional urea for nitrogen supplementation. This revolutionary technology reduces nitrogen fertilizer use by 50%, cuts input costs, reduces environmental pollution from excess urea, and represents India's innovative contribution to the Second Green Revolution.

Correct Answer: B. Cooperative model owned by farmer-members with professional management, not government-controlled

The White Revolution's cooperative model was owned by the dairy farmer-members themselves with professional management — unlike typical government schemes run by bureaucrats. This gave farmers ownership, profit-sharing, and motivation to supply quality milk. The Amul model's three-tier structure ensured transparency and democratic governance. Verghese Kurien insisted on farmer-owned, professionally managed cooperatives rather than government bureaucracies, which was the key to their sustainable success.

Correct Answer: B. Increased from ~124 grams/day (1950s) to ~427 grams/day (2022)

India's per capita milk availability increased dramatically due to the White Revolution — from about 124 grams per day in 1950-51 to 444 grams per day by 2021-22, exceeding the WHO recommendation. This improvement in dairy availability significantly enhanced India's nutritional situation, providing protein, calcium, and micronutrients, particularly for children and women. The cooperative dairy network made affordable milk accessible across urban and semi-urban India.

Correct Answer: B. Using AI, IoT, satellite data, and digital platforms to transform agricultural decision-making and services

Digital agriculture represents the newest phase of agricultural revolution, using AI/machine learning for crop monitoring, IoT sensors for precision irrigation and soil monitoring, satellite remote sensing for crop mapping, and digital platforms for market access, advisory services, and financial inclusion. India's Digital Agriculture Mission aims to create a digital ecosystem for agriculture using Agri Stack (farmers' database, land records, crop sown layer) as foundation for targeted service delivery to farmers.

Correct Answer: B. Indian Council of Agricultural Research — network of 100+ research institutes generating technologies for all agricultural revolutions

ICAR (Indian Council of Agricultural Research), established in 1929, is the apex body coordinating 100+ research institutes and agricultural universities across India. ICAR institutes developed HYV crop varieties for the Green Revolution (IARI), improved animal breeds for the White Revolution (NDRI), fisheries technologies for the Blue Revolution (CMFRI), and continues generating technologies for all agricultural sectors. ICAR is the scientific backbone enabling each of India's sequential agricultural revolutions.

Correct Answer: B. Seeds and crop genetic diversity that enabled Green Revolution should be freely shared, not privatized

The concept of plant genetic resources as 'common heritage of mankind' argues that crop genetic diversity accumulated over millennia by farmers worldwide should be freely available for breeding programs that enable agricultural revolutions. This principle, championed by India and developing countries at FAO, counters the trend of plant variety patents and corporate monopolization of seed genetics. The International Treaty on Plant Genetic Resources (2001) balances farmers' rights with access and benefit-sharing principles.

Correct Answer: B. Among top 2-3 globally in milk, pulses, tea, jute, spices; top 5 in rice, wheat, cotton, fruits, vegetables

India's agricultural revolutions have made it a global agricultural powerhouse: world's largest producer of milk, pulses, jute, spices, and bananas; 2nd largest in rice, wheat, cotton, sugarcane, fruits, and vegetables; top fish producer; major exporter of rice, spices, cotton, and buffalo meat. This production diversity reflects the cumulative success of all the sectoral revolutions — Green, White, Blue, Yellow, Golden, and Silver — over six decades.

Correct Answer: B. Integrated trees, crops, and sometimes livestock on the same land for sustainable productivity

Agroforestry integrates trees with agricultural crops and/or livestock on the same land, creating diversified production systems. Trees provide multiple benefits: improve soil health through leaf litter, fix nitrogen, provide shade and microclimate benefits, diversify income through fruits/timber, and sequester carbon. Agroforestry embodies Evergreen Revolution principles — it increases productivity while enhancing ecological sustainability, biodiversity, and climate resilience simultaneously.

Correct Answer: B. Developing processing, storage, transport, and marketing infrastructure to increase farmer's share of consumer price

Value chain development for agricultural produce involves creating infrastructure (cold storage, processing units, grading, packaging, logistics) that reduces post-harvest losses, increases shelf life, adds value through processing, and improves market access. Farmers capturing more value from the chain — rather than middlemen — is central to Doubling Farmers Income. FPOs and cooperatives help farmers move up the value chain from raw commodity sales to processed and branded products.

Correct Answer: B. Converting crop residue and agricultural waste into biogas, biofuels, and bioproducts for additional farmer income

India generates enormous quantities of agricultural waste (crop residue, animal dung, food processing waste) that has significant bioeconomy potential. Converting these into biogas (energy), bio-CNG, biofertilizers, biochar, and bioplastics creates additional farmer income, reduces pollution from crop burning, and advances India's circular economy goals. GOBARdhan (Galvanising Organic Bio-Agro Resources Dhan) scheme harnesses dung and agricultural waste for biogas, exemplifying this bioeconomy revolution.
