The Green Revolution in India is a good example of a planned development initiative that brings out all the essential features of the development process. Until 1960 agriculture in India did not differ markedly from what it had been during the colonial period stretching back 200 years ago. The Green Revolution is usually described as the introduction of hybrid varieties of wheat and rice, but the adoption of hybrids alone is not sufficient to explain the phenomenal achievements of the Green Revolution. Success was made possible by a comprehensive and well-coordinated program involving multiple changes in the way society managed the production of food.
