The correct answer is High Yielding Variety

Key Points

  • The term High Yielding Variety (HYV) refers to seeds that are engineered to produce more crops per area planted compared to traditional varieties.
  • The introduction of HYV seeds was a crucial component of the Green Revolution, which significantly boosted agricultural productivity, particularly in developing countries.
  • These seeds are often more resistant to pests and diseases and can grow in a variety of climatic conditions, making them highly adaptable.
  • The use of HYV seeds typically requires the application of modern agricultural techniques, including the use of fertilizers and irrigation.
  • While HYV seeds have contributed to increased food production, they also necessitate careful management to avoid issues such as soil degradation and water resource depletion.

Additional Information

  • The Green Revolution began in the 1960s and was marked by the adoption of new agricultural technologies, including HYV seeds, chemical fertilizers, and pesticides.
  • It led to a substantial increase in food grain production, particularly in countries like India and Mexico.
  • The Green Revolution played a significant role in transforming agriculture from subsistence farming to commercial farming, making many countries self-sufficient in food production.
  • However, the Green Revolution also brought challenges such as environmental damage, increased inequality among farmers, and the marginalization of smallholders.
