Answer:
30 years ago, rain water, wells, rivers, animals etc were used for irrigating the fields. Even the produce was handpicked as there was no machines. Later, pump wells, tube wells, Persian wheels, pulley system, chain pump came into use. After green revolution, drip irrigation, sprinkler techniques were introduced. In the 1990’s, during the "seventh five year plan", emphasis was laid on completion of dam building projects so that canals could be build to supply water to fields. Due to the introduction of "fertilisers and irrigation methods", production increased drastically.
