a)Fertilizers:
The use of chemical fertilizers has increased the production of food grains to large extent. In 1965-66 chemical fertilizers were used 97 thousand tonnes. In 2002-03, their use increased to 1441 thousand. b) High Yielding Variety of Seeds (HYV):
The use of HYV seeds have played major role in increasing agricultural production. For example, per hectare yield of wheat has increased from 1200 kgms to 4500 kgm. In case of rice the yield increased from 1000 kgms to 3500 kgms. So HYV seeds has increased the production tremendously.
