Second phase of Green Revolution is termed from:

The correct option is mid 1970s to mid 1980s.

Explanation:

The Green Revolution in India refers to a period when Indian agriculture was converted into an industrial system due to the adoption of modern methods and technology such as high-yielding variety (HYV) seeds, tractors, irrigation facilities, pesticides, and fertilizers. It is generally divided into two distinct phases:

1. First Phase (mid-1960s to mid-1970s): During this initial phase, the use of HYV seeds was restricted to relatively affluent states such as Punjab, Andhra Pradesh, and Tamil Nadu. The benefit of the Green Revolution primarily favored wheat-growing regions.

2. Second Phase (mid-1970s to mid-1980s): During this phase, the HYV technology spread to a larger number of states and benefited a wider variety of crops (including rice and others). This phase marked a more widespread and inclusive growth across different regions of the country.

Therefore, the second phase of the Green Revolution is termed from the mid-1970s to the mid-1980s.
