Abstract: This study was conducted to analyze the fate of agriculture land-use change (LUC) for major crops of the country viz. rice, wheat, maize, cotton and sugarcane, during 1961-2014, grounded on previously available data. Improvement in area and yield was a result of the use of high yielding cultivars and government policies and strategies of fertilizer-use during the period. Fertilizer-use in all major crops increased from 1961-2014, however, its efficiency with time decreases significantly. Per capita production of all major crops improved during 1961-2014, illustrating that more population was engaged in agriculture during this period and overall cereal production boosted during this time. Similarly, an increase in production per unit area and yield per capita was observed because of increased input, particularly chemical fertilizer during 1960s. However, a drop in yield per unit chemical fertilizer appears to be an outcome of fertilizer satiety, soil problems, natural hazards like floods, earthquake, less availability of irrigation, as well as, economic and social issues. The problems of increasing industrialization, urbanization, and inadequate reclamation of land resources, growing food demand can be overcome principally by augmented land productivity. Current study may help policy makers to design sustainable land-use policies for future.
