Summary: | The initiative taken in the late 1960s and early 1970s to make the country
self-reliant to meet the food requirement resulted in a shift from traditional
agriculture to intensive farming involving stepped up use of chemical fertilizers and pesticides (Goyal, 2001; Tandon, 1992). The steps that
brought the green revolution in the country in the long run have turnedCONTENTS5.1 Introduction ... 169

pesticides contaminated the ground water, which gets reected in our daily
diet. These detrimental effects of current agricultural practices can be appreciably reduced by using biofertilizers in combination with organic manure
and chemicalfertilizers and induce long-term sustainability in agricultural
production (Tandon, 1992). |
