Green Revolution — Study Notes
Overview
The Green Revolution was a landmark transformation in Indian agriculture during the mid-1960s that dramatically increased food grain production, particularly wheat and rice. For UPSSSC PET candidates, this topic is crucial because it appears in questions about economic planning, agricultural development, and India's journey from food scarcity to self-sufficiency. You must understand the key scientists involved (Norman Borlaug and MS Swaminathan), the technology package (HYV seeds, irrigation, fertilizers), and the uneven regional impact that favored Punjab, Haryana, and western UP while leaving eastern regions behind.
The Green Revolution began around 1966-67 when India faced severe food shortages and relied heavily on PL-480 food imports from the USA. The introduction of High Yielding Variety (HYV) seeds, combined with chemical fertilizers, pesticides, and assured irrigation, resulted in spectacular productivity gains. Within a decade, India moved from "ship-to-mouth" existence to becoming self-sufficient in food grains by the early 1970s. This achievement not only solved the immediate food crisis but also laid the foundation for India's agricultural policy for decades to come.
Understanding both the achievements and limitations of the Green Revolution is essential. While it brought food security, it also created regional imbalances, environmental concerns, and socio-economic disparities that persist today. Exam questions often probe these dual aspects—the successes and the associated problems.
Key Concepts
• **HYV Seeds**: High Yielding Variety seeds are dwarf varieties of wheat and rice that respond strongly to chemical fertilizers and irrigation, producing 3-4 times more yield than traditional varieties. These seeds required a complete package of inputs—irrigation, fertilizers, and pesticides—to deliver promised results.
• **Technology Package Approach**: The Green Revolution was not just about seeds but a complete package—HYV seeds + assured irrigation + chemical fertilizers + pesticides + farm mechanization. All components had to work together; missing even one element would drastically reduce effectiveness.
• **Food Self-Sufficiency**: By 1971, India achieved self-sufficiency in food grains, ending dependence on foreign food aid. Wheat production rose from 12 million tonnes (1964-65) to 28 million tonnes (1970-71). This was the primary achievement that saved India from chronic famines.
• **Regional Concentration**: The Green Revolution succeeded primarily in Punjab, Haryana, western Uttar Pradesh, and parts of Andhra Pradesh and Tamil Nadu—areas with assured irrigation facilities. Eastern states like Bihar, West Bengal, and Odhra remained largely untouched, creating a "green revolution divide."
• **Crop-Specific Impact**: Initially focused on wheat (1960s), later extended to rice (1970s). Other crops like pulses, oilseeds, and coarse cereals did not benefit, leading to imbalanced crop production patterns that persist today.
