Explanation
Why Correct: The Green Revolution, launched in the mid-1960s with high-yielding variety (HYV) seeds of wheat and rice, dramatically increased wheat productivity, especially in Punjab, Haryana, and western Uttar Pradesh. It also widened regional inequalities because states with assured irrigation and better infrastructure adopted the new technology faster, while rain-fed areas lagged. Interpersonal inequalities grew as large farmers, who had better access to credit, fertilizers, and extension services, captured most of the gains, leaving small and marginal farmers behind.
Distractor Analysis: Examining the statements: Wheat productivity increased markedly due to HYV seeds, chemical fertilizers, and irrigation, making that statement true. Regional inequalities increased because the Green Revolution's benefits concentrated in a few well-irrigated states, while other regions remained stagnant. Interpersonal inequalities increased because richer farmers could afford the costly inputs and mechanization, while poorer farmers could not, widening the income gap.
Takeaway: The Green Revolution primarily boosted wheat and rice yields, but its uneven spread contributed to the rise of regional disparities and the concentration of benefits among larger landowners, a pattern often tested in Indian economy exams.
