Abstract
The twin objectives of increasing agricultural production and profitability at crop farm level have received widespread attention in farm production economies across the world. This is more so in India where agriculture continues t dominate in economic development, accounting one third of the gross domestic product and one fifth of foreign exchange. This sector absorbs about 52 percent of the total lab our force(2004-2005) in the country and its contribution through links with manufacturing, distribution and services are very significant. Nearly 80 percent of the country’s population still live in rural areas and are wholly or significantly dependent on agriculture and allied activities for their livelihood. The input system of the country too presents the fact that India is a country of ever expanding resource structure capable of meeting out the demand for agriculture, particularly in the context of increasing crop yield.
