Agriculture is the main occupation in India and about 75% of its
population depends directly or indirectly on agriculture for their
livelihood. It is the dominant sector that contributes 18% of the
gross domestic product. Thus, agriculture is the foundation of the
Indian economy. The maximum share of Indian exports is also from
the agriculture sector. As the population of the country is
increasing trem- dously, approximately at the rate of 19 million
every year over the existing popu- tion of more than 1 billion
(approximately 1. 18 billion), the food grain production must
necessarily be increased. This can be done by increasing crop
production to match the population growth rate of 2. 2% per annum,
which is expected to stabilize at 1. 53 billion around 2050. There
is no doubt that the Green Revolution in India during the late
1960s brought self-sufficiency in food grain production, mainly
through the increase in rice and wheat crop yields - the two main
crops of the country which play an important role from food
security point of view. However, the excessive use of fertilizers
and pesticides, and the neglect of organic manures for these crops,
has resulted in the deterioration of physical, chemical and
biological health of the ri- and wheat-growing soils. Owing to the
deterioration of the health of these soils, the productivity of the
rice-wheat cropping system has now either got reduced or in some
places has become constant for the last decade.
