Abstract

Yields of organic agriculture have been the center of many debates about the advantages or disadvantages of organic management. Recently, evidence has been accumulating that yields under organic management are, on average, 19%–25% lower than under conventional management. But there remain many open questions, including (1) the factors contributing to low or high yield gaps between organic and conventional agriculture, (2) whether yields on organic farming system trials can be replicated on farmers’ fields, (3) the impact of organic management on yield stability, and (3) the comparative yields of organic agriculture at the cropping system level. This chapter provides an overview of the existing evidence on each of these points, while also highlighting important knowledge gaps. In addition, this chapter highlights that - given the limited attention from agricultural research and extension that organic agriculture has received to date - there is ample room to address yield-limiting factors in organic systems and to improve organic yields.
