      abstract = {The quantity of wheat supplied in the RSA and the  different production regions arc significantly innucnced by  a variety of factors, including time, climate, wheat  prices, prices of production substitutes such as maize,  mutton, wool and sorghum, and input costs. By using  multiple regression techniques the effects of these factors  on the area under wheat and the production of wheat in the  various production areas were isolated and quantified The  different supply equations seem to yield significant  results within acceptable statistical norms and can thus be  fruitfully used for predictions.},
