Given its remarkable productivity and earnings benefits, the low uptake of SRI seems rather puzzling. One mooted cause of such low uptake is that SRI requires more labor inputs. While the use of hired labor is common, it is usually limited to simple tasks, such as transplanting and harvesting, for which hired workers are paid piece rate wages. Core activities that require greater care and judgment are implemented exclusively by family labor. A detailed analysis of our data confirms that family labor inputs per hectare are statistically significantly larger for SRI plots than non-SRI plots, that is, 64 versus 54 person days. Barrett et al. (2004) find that SRI’s labor requirements fall with greater years of SRI experience. In our data, however, there is no discernible change in family labor input per hectare on SRI plots out to seven years of SRI experience.
