Abstract
Since Sri Lanka is approaching self sufficiency in rice more attention should now be paid to the development of subsidiary food crops (SFCs). The objective of this study is to develop an econometric model to explain the demand for cow pea,gingelly,green gram and groundnut. Demand stnicnine for SFCs would be useful as it would enable us to determine the effect of future changes in food policy on consumptiom pattens of SFCs and in the estimation of the food supply requirement of the country. The models were estimated using zellner's seeminaly unrelated regression (SUR)method.
The results indicate that the demand for cow pea, groundnut and gingelly was relatively less responsive to income but highly responsive to own price. However, the demand for green gram is less responsive to own price but highly responsive to consumer income.
