Spillover impacts of sorghum research

A technological breakthrough in agriculture often leads to increased yields, or improves the quality of output, or enhances the efficiency of input use. If the new technology has applicability beyond the confines of the location for which it was generated, or beyond the commodity for which it was developed, such an effect is commonly referred to as spillover effects. A review (Deb and Bantilan 2001) of the spillover impacts of agricultural research has covered the evolution of the concept over time, different types of spillovers dealt in literature and techniques to quantify spillover impacts by different studies on the subject...
