Is there any way one can grow more from the same land?

One can grow more on a piece of land by the method of multipple cropping.In this method the farmers should grow more than one crop on a piece of land.By using H.Y.V's,chemical fertilizers,pesticides and modern irrigation facilities the production on a given piece of land can be increased.Farmers of Punjab,Haryana and western U.P used modern farming methods and increase the production in 1960 which is known as green revolution.
