The original idea of the green revolution came from the southern Asia in the mid 1960`s. the purpose of the revolution was to use modern technology in agriculture in developing countries in order to increase food production.
The rapid increase in cereal food production is what is called the green revolution.
The green revolution involves the introduction of use of high yielding varieties (high breeds) of cereals like rice, wheat, maize (corn) and millet, improvement in farm technology and fertilizer production and use of chemicals such as weed killers and insecticides are also being encouraged and extension of irrigation to avail water when it is needed in the field.
GENERAL FEATURES OF THE GREEN REVOLUTION
High yield varieties of cereals are being encouraged for example wheat, rice, maize, barley and many others. These replaced the low yielding traditional strains. Irrigation farming system has been introduced in the system to cater for periods of low rainfall.
There is increased use of farm machineries for example tractors, combune harvesters and many others which boosts mass production of cereal.
The development of new hybrids with a shorter growing season for example in Asia which has promoted double cropping of rice a practice which was never heard of.
The development of cereal types which resist diseases, drought and many others. This is done by inter breeding, grafting the traditional breed with the new fast yielding developed in Mexico.
Increased use of fertilizers to increase te fertility of the soil and subsequent productivity.
The wider provision of credit by the government so that irrigation pumps could be bough and new wells sunk to tap water, machines installed and many others.
