Keywords: world fertilizer consumption, predicted world pesticide use, major inputs into farming systems, Green Revolution technology for rice was based on high-yielding varieties of wheat and rice that responded to high inputs of nitrogenous fertilizers and irrigation, fertilizer efficiency is reduced in the tropics due to rapid leaching of nitrogen and greater degree of phosphorous fixation, components of sustainable agricultural systems, pesticides are often used as recommended by chemical dealers or on an insurance basis, many of the applications used may be unnecessary and/or economically unsound, herbicide applications can be replaced by use of mechanical control, use of crop rotations, cultivations –use of the moldboard plows that involves high energy consumption to pull the plow, low input systems of involving crop rotations, strip cropping, lighter machinery, organic matter inputs, crop breeding, integration of components
