What is the role of Technological and Institutional reforms in agriculture?

Technology has taken human from land to sky. Today almost in every field we can see its impact. It is not different with agriculture. New technological machines can do the same work in an hour which will be difficult for man farmers to do in almost a day. Earlier sickle was used for harvesting but now we have developed harvesters. It certainly helps our production to increase many folds in a small period of time.
