Randomized survey experiments implemented in Uganda and Mali have tested the relative accuracy and cost effectiveness of crop production and yield measurement based on farmer-reporting vis-à-vis crop cutting. The empirical evidence has showcased systematic errors (and over-reporting) in farmer-reported crop production estimates (maize in Uganda and sorghum in Mali)--particularly in the lower half of the plot area distribution, with direct implications for the inverse scale-productivity relationship. The results from the methodological experiments have been further validated by analysis of the data collected as part of the LSMS-ISA-supported Ethiopia Socioeconomic Survey. LSMS-ISA is now considering the integration of crop cutting into future survey efforts, for selected crops and on a sub-sample basis.
