Chapter Overview

After independence, India chose the path of planned development under a mixed economy model — combining public and private sectors under successive Five-Year Plans. The period 1950–1990 saw ambitious industrialisation, the Green and White Revolutions in agriculture, but also the stifling effects of the "permit-licence raj" and a frustratingly slow GDP growth rate.

This chapter covers the goals and evolution of Five-Year Plans, the Nehru-Mahalanobis heavy industry strategy, transformative agricultural revolutions, and the structural contradictions of the Indian economy before 1991 liberalisation.

Key Topics

Key Concepts at a Glance

Concept 1
Nehru-Mahalanobis Model 2nd Five-Year Plan model. Prioritised heavy/capital goods industries (steel, machinery) over consumer goods. Rationale: capital goods enable future growth. Led to PSU dominance in core sectors.
Concept 2
Green Revolution 1960s–70s. HYV (High Yielding Variety) seeds + chemical fertilizers + irrigation → dramatic increase in wheat and rice production. Mainly benefited Punjab, Haryana. Key figure: M.S. Swaminathan.
Concept 3
White Revolution Operation Flood (1970–1996) by Verghese Kurien / NDDB. Built dairy cooperatives across India. Made India world's largest milk producer. Amul is the iconic brand.
Concept 4
Hindu Rate of Growth Term coined by economist Raj Krishna for India's ~3.5% average annual GDP growth in 1950–1980. Widely seen as below potential due to excessive government controls.

Detailed Notes

Five-Year Plans — Goals and Strategy
India's Planning Commission (established 1950) designed Five-Year Plans with four broad goals: Growth (increase national income), Modernisation (adopt new technology and methods), Self-reliance (reduce dependence on imports and foreign aid), and Equity (distribute benefits widely, reduce inequality). The First Plan (1951–56) focused on agriculture and rehabilitation, including the Bhakra Nangal dam project, and largely met its targets.

Nehru-Mahalanobis Model (Second Plan, 1956–61)
Designed by statistician P.C. Mahalanobis and championed by Prime Minister Nehru, the Second Plan's strategy was to invest heavily in heavy industries — steel, machinery, chemicals — rather than consumer goods. The logic: capital goods (machines that make machines) would create the productive base for sustained long-run growth. This led to the establishment of major steel plants at Bhilai (Soviet collaboration), Durgapur (British collaboration), and Rourkela (German collaboration). The public sector expanded massively into what the Industrial Policy Resolution called "commanding heights" of the economy.

Green Revolution
By the early 1960s, India faced severe food shortages and was dependent on US food aid (PL-480). The Green Revolution was a technological breakthrough: introduction of High Yielding Variety (HYV) seeds (especially for wheat — the Mexican dwarf varieties), combined with chemical fertilizers, pesticides, and assured irrigation. Led by agricultural scientist M.S. Swaminathan, the results were dramatic — wheat production tripled, rice production doubled. India achieved food self-sufficiency by the mid-1970s. However, the revolution was geographically uneven (mainly Punjab, Haryana, western UP) and increased rural inequality between those who could afford inputs and those who could not.

White Revolution — Operation Flood
The dairy cooperative movement, spearheaded by Verghese Kurien through the National Dairy Development Board (NDDB) and the iconic Amul cooperative (Gujarat), transformed India's dairy sector. Operation Flood (1970–1996) created a nationwide network of milk cooperatives, connecting rural milk producers directly to urban consumers and eliminating middlemen. India became the world's largest milk producer — a success story of cooperative enterprise.

Permit-Licence Raj and Its Problems
To implement the plan, the government created an elaborate system of industrial licensing — any entrepreneur wishing to set up or expand a factory needed licences from multiple government departments. This "permit-licence raj" (also "Inspector Raj") became notorious for bureaucratic red tape, corruption, and inefficiency. It protected existing producers from competition but stifled innovation and entry of new firms. The system was a major reason for India's slow growth relative to East Asian economies.

Sample Practice Questions

Q1. The Second Five-Year Plan was based on which model?
  1. Harrod-Domar
  2. Nehru-Mahalanobis ✓
  3. Lewis two-sector
  4. Solow growth
The Second Plan (1956–61) was explicitly based on the Nehru-Mahalanobis model, which prioritised investment in heavy capital goods industries. P.C. Mahalanobis designed the mathematical framework; Jawaharlal Nehru provided the political vision.
Q2. Green Revolution in India primarily led to increase in production of:
  1. Rice and cotton
  2. Wheat and rice ✓
  3. Oilseeds and pulses
  4. Sugarcane and jute
The Green Revolution primarily boosted wheat production (tripled) and rice production (doubled). HYV wheat seeds were the initial breakthrough, followed by HYV rice. Cotton, oilseeds, and pulses were largely unaffected by the first phase of the Green Revolution.
Q3. (Numerical) India's GDP growth rate averaged 3.5% in 1950–1980. If GDP in 1950 was ₹100, approximately what was it in 1980 using simple (non-compound) growth?
  1. ₹135
  2. ₹200
  3. ₹205 ✓
  4. ₹250
Simple growth: 3.5% per year × 30 years = 105% total increase. Starting from ₹100: ₹100 + ₹105 = ₹205. Note: compound growth would give ₹100 × (1.035)³⁰ ≈ ₹281, but the question specifies simple growth.
