Final answer:
The Green Revolution improved agricultural production mainly through the introduction of high-yield crop varieties, expanded irrigation, and the use of chemical fertilizers. The implementation of organic farming was not a part of the Green Revolution, thus making it the outlier among the given options.
Step-by-step explanation:
The Green Revolution refers to a series of technological advancements that occurred between the 1940s and the 1970s aimed at increasing agricultural production worldwide. Significant developments included the introduction of high-yield crop varieties, such as the semi-dwarf wheat and rice, which were designed to produce more grain per plant and resist certain diseases. These high-yield varieties (HYVs) also responded positively to chemical fertilizers and expanded irrigation systems, allowing them to produce significantly higher yields under optimal conditions. The Green Revolution also saw the increased usage of chemical fertilizers and synthetic pesticides to enhance crop growth and prevent losses from pests and diseases. However, the implementation of organic farming was not a part of the Green Revolution; in fact, the movement was characterized by its adoption of modern, synthetic inputs to boost agricultural outputs.
Although the Green Revolution led to substantial yield improvements and helped to prevent the predicted famines of the 1960s, it also resulted in socio-economic and environmental issues. These included increased dependency on synthetic inputs, which impacted traditional farming practices and led to social inequality and environmental degradation such as soil erosion and loss of soil fertility. While it brought an expansion of food production, the Green Revolution's preference for modern agriculture techniques did not generally include organic farming methods, which prioritize the use of natural substances and processes for pest control and soil fertility.
The option that does not improve agricultural production via the Green Revolution is c) implementation of organic farming, making it the correct final answer.
