ABSTRACT

Wheat plays a very important role in maintaining the country's sustained food security. The only way to increase its production is obviously through enhancement, in its productivity. In this paper, our purpose is to critically examine the pattern of statewise wheat productivity data during the period 1973–74 to 1996–97 in respect of four major wheat growing States, viz. Punjab, Haryana, Uttar Pradesh, Rajasthan as well as at the all-Innia level. To this end, attempts were made to apply a number of nonlinear mechanistic growth models. Logistic and Gompertz models were found to be quite successful in describing the path of wheat productivity. Forecast values were also computed on the basis of the selected models. A comparative study indicated that Haryana's performance was the best among the major wheat growing States
