The statement is -False.
The amount of people working into the agricultural field, despite the much increased population of the country, has remained largely the same. This is a result mainly due to the mechanization. Since the mechanization is enabling the farmers to work on the land much quicker and more efficiently, with the mechanization replacing lot of labor human force, the amount of farmers is pretty much the same, but the production has increased significantly. As the technology develops, the same amount of people are managing to produce more and more, and human labor force is just not needed in large amounts, as the mechanization is doing most of the job.
