Wheat Production Under Alternative Production Functions

In an earlier study [1, pp. 407-415] it was assumed that a linear production function would be the best to depict the relationship between wheat production and explanatory variables in the Punjab. After a careful scrutiny, four of the explanatory variables, viz., area under Mexican Wheat varieties, area under local wheat, fertilizer application and rainfall, were employed to explain variations in wheat production. As this linear relationship gave a good fit, it was claimed that the equations, derived from 1967-68 to 1971-72 output and input data, can be useful in forecasting wheat production in the Punjab for future years well in advance of actual wheat harvests and, in fact, a forecast of wheat production in the Punjab for 1973-74 was published [2, pp. 106-112], based on the findings of that model
