What is the Green Revolution primarily associated with?

The Green Revolution is primarily associated with significant advancements in agricultural technology that transformed farming practices in many parts of the world, particularly between the 1940s and the late 1960s. This period saw the introduction of high-yielding varieties of staple crops, such as wheat and rice, along with better irrigation and fertilization techniques. These innovations aimed to increase food production to meet the needs of growing populations, especially in developing countries.

The introduction of hybrid seeds, the extensive use of chemical fertilizers and pesticides, and advancements in irrigation methods all played a crucial role in improving crop productivity during this era. The focus was on maximizing yields to combat hunger and enhance food security, which fundamentally changed agricultural practices globally.

In contrast, the other options do not encapsulate the essence of the Green Revolution. New herbicides, organic farming techniques, and conventional crop rotation practices may relate to agricultural developments but are not the defining characteristics of the Green Revolution, which is primarily marked by its technological innovations aimed at enhancing food production.
