Implications of the Green Revolution for Land Use Patterns and Relative Crop Profitability Under Domestic and International Prices

Mohammad Afzal


The 'Green Revolution' of the late sixties was caused by the
development of high responsive seeds (HRS) and the increased
availability of irrigation water. New dwarf varieties of rice and wheat
developed for tropical and sub┬Čtropical regions have a higher
grain-nutrient response than traditional varieties. Potential increase
in yields per acre with the introduction of HRS are of the order of 50
to 200 per cent, given sufficient doses of chemical fertilizers and
proper cultural practices [2, p. 58]. Since the introduction of HRS is
confined to wheat and rice, the relative productivity of competing crops
has changed substantially. In addition to government policies of input
subsidies (water and fertilizers), price support (wheat and rice),
protection (sugar-cane), and an overvalued exchange rate have affected
the profitability of crops unevenly. This has provided an incentive to
the farmers to change their land use patterns. This paper analysis the
impact of the 'Green Revolution' and Government policies to assess the
resulting efficiency of land use.
