Monoculture is the agricultural practice of producing or growing a single crop or plant species over a wide area and for a large number of consecutive years. It is widely used in modern industrial agriculture and its implementation has allowed for large harvests from minimal labour. However, this ratio remains true only if the accounting for labour required is limited to the number of workers employed on the farm. If the indirect work of employees involved in producing chemicals and machinery are taken into account, the ratio of labour to output is higher.

The Introduction of High-yielding varieties of seeds and the increased use of fertilizers and irrigation are known collectively as the Green Revolution, which provided the increase in production needed to make India self-sufficient in food grains, thus improving agriculture in India. Genetically modified high-yielding wheat was first introduced to India in 1963 by Dr. Norman Borlaug. A proper facility of irrigation water was also key feature of the agricultural strategy behind Green Revolution.
