Change in technology in Indian agriculture started in 1960s with the introduction of high yielding variety of seeds, fertilizers and mechanisation. These modern inputs require assured water supply to the crops. The four modern inputs are as follows : 1. High Yielding Variety of Seeds: HYV seeds are the product of modem technology. It has increased the yield per hectare tremendously. Now, HYV seeds are used in almost every crop. New HYV of seeds for wheat and rice were brought to India from Mexico and Philippines respectively. HYV seeds for jowar and maize were also introduced. The use of HYV seeds increased the production of crops phenomenally. In 1966 – 67, area under HYV of seeds was only 1.89 million hectares and increased to 71.3 million hectares in 1994 – 95. In 2001, 90.6 percent of total wheat cropped area is under HYVs. Example of HYV seeds are : Wheat: Kalyansona, Sonalika. Rice: IR – 36, IR – 58. 2. Fertilizers: The use of fertilizers is an important factor of modern technological inputs in the agricultural field. The production and consumption of fertilizers has increased many fold after the independence. The consumption of fertilizers was only 760 thousand tones of nutrients in 1965-66. It rose to an all times high of 18,069 thousand tones nutrients in 1990-2000. 3. Modern Equipment’s of Agriculture: The modern equipments of agriculture have made the agriculture productive and easy. 4. Irrigation: The supply of water for irrigation through canals or tube wells has increased the production of crops and has also led to the increase in net cropped area
