Green revolution | high yielding grain varieties

Green Revolution is a significant increase in agricultural productivity which is resulted from the introduction of grain varieties that are high-yielding, application of insecticides and pesticides, and well-developed management techniques. 

Doctor Borlaug is the father of the Green Revolution.  He revolutionized the agricultural industry.  He introduced the high yielding varieties of wheat in 1950.  Doctor Borlaug had a concept that for the production of Agricultural goods a man should not depend upon nature.  Man efforts can increase agricultural goods. The green revolution has increased the quality and quantity of outputs of agriculture.

Factors responsible for the Green Revolution

  •     Miracle seeds 

   High yielding varieties of seeds brought about a revolution in agriculture. The yield of agriculture per hectare has very much increased by the introduction of new seed varieties.  In 1971-72 the wheat yield was 11 89 kg per hectare in Pakistan, 

Agricultural Research 

    Reproduction outputs are results of the research of agriculture that has the main objective of producing higher-yielding plant varieties.

  • Fertilizers 

 The rapidly increasing agricultural production is due to the application of chemical fertilizers.

  • Multiple cropping 

 New varieties of seeds mature early, so from the same piece of land instead of one or two crops farmers can get three or four crops in a year.

  • Modern machinery 

Blocks cultivation is replaced by modern machinery such as threshes harvesters Tractors and tube wells. This modern machinery is time-saving,  so the farmers can grow and harvest crops in a short time period.

Advantages of the green revolution

 There are the following positive impacts of the Green Revolution.

  • The crops that have the ability to resist pests and herbicides are the main best gift of the Green revolution.
  • Why modern farming techniques farmers are able to regrow the same crop without danger of fallowing their lands.
  • By using modern techniques farmers can grow crops in most types of land.  Fertile banks of the river are not necessary to start forming.
  • Before the Green Revolution, most of the worldwide farmers were poor,  after the green revolution today’s farmers are richer. The monoculture system of farming has been neglected with modern farming techniques.
  • The green revolution has much more improved health and diet.
  • The green revolution has increased the productivity of croplands without increasing the acres,  it also has made the food prices cheaper.
  • The green revolution has also protected our environment, due to higher yield few forests are converted into land for agriculture for the production of food.
  • Poor harvest always resulted in a poor season.  By the use of modern farming techniques, the annual harvest is constant each year.
  • Inner lower-income nations poverty has been reduced by the Green Revolution,  due to Healthy foods that are produced by hybrid crops.

Some drawbacks of Green Revolution

There are some drawbacks of the Green Revolution.

  • Intense agriculture has destroyed the fragile agroecosystem
  • Green revolution has reduced the  natural fertility of the soil
  • Water resources are diminishing due to modern farming techniques.
  • Soil toxicity and erosion of soil is resulted in such forming techniques.
  • Fertilizers are polluting the underground water resources.
  • The green revolution also causes Global Warming
  • The salinity of underground water has been increased
  • Over adopted agricultural techniques have increased livestock and human diseases.
  • Soil water and air are gradually polluted by the indiscriminate chemical uses.
  • Urea is rich in nitrogen,  urea is used beyond the recommended level so  Global warming results.
  • Poisonous Chemicals have reduced the fertility of Agricultural lands of millions of hectares.
  • Indiscriminate use of agrochemicals has poisoned the underwater resources, pond water, and the water of rivers.
