Explanation:

The Green Revolution in India, initiated in the mid-1960s, primarily focused on dramatically increasing the production of major cereal crops, particularly wheat and rice, through the introduction of High-Yielding Varieties (HYVs), improved irrigation, and chemical fertilizers. While it significantly boosted the output of wheat, rice, and to some extent maize, its impact on other crops like barley, pulses, and oilseeds was limited. Barley did not experience a substantial increase in production as a direct result of the Green Revolution's core strategies. Rice, wheat, and maize all saw considerable gains.
