Multiple regression analysis has been widely used to examine the impact of weather on crop yield, but with little success because annual rainfall has almost invariably been used as a measure of the weather conditions. The purpose of this paper is to propose a composite weather index which takes into account all aspects of weather, treating it as a multidimensional phenomenon. This index is then used to explain variations in the yield of the apple crop in four districts of Himachal Pradesh.
