Profitability Analysis of Zero Tillage among Smallholder Farm Households in the Karak Region of Jordan

There is rich literature on the biophysical benefits of zero tillage (ZT) while that on its economic benefits, especially in the context of small and medium-scale farmers, is scanty. Using a combination of Propensity Score Matching (PSM) and Endogenous Switching Regression (ESR) models and a case study from a large project which promoted a number of technologies including zero tillage in the Karak region of Jordan, this study attempts to provide evidence on the profitability of ZT.
