Introduction of high yielding varieties (HYVs) coupled with expansion of irrigation
facilities, and increased use of chemical fertilizers and other agro-chemicals have brought about
spectacular increases in the yield of crops, particularly rice and wheat. About half of the total
increase in food grain era has been attributed to the use of fertilizers and more than one-third of
this increase is due to N fertilizes alone. The country has still about 65 per cent area under rainfed,
and only about 35 per cent area under under irrigation. Low water use efficiency (WUE) has been
the concern as the availability of water for agriculture is decreasing day by day. For saving and
effective utilization of this vital resource, proper management strategies involving agro-techniques
should be developed. Inefficient inputs/fertilizer use is a key factor pushing the cost of cultivation and pulling
down the profitability in farming. Total factor productivity (TFP) is used as an important measure
to evaluate the performance of a production system and its declining trend is a serious issue. A
fatigue in the ratio between the inputs and output is indicative of TFP deceleration with
concomitant unsustainability of crop productivity. The challenge is how to increase food
production in the country by around 60 per cent over next two decades without jeopardizing the
soil and water resources which are already under great stress. With increased demand for cereals,
pulses and cooking oil, the productivity per hectare or unit input is decreasing. Thus the risks of
degradation of natural resources soil
