Crop yield estimation from satellite data requires field observations to fit and evaluate predictive models. However, it is not clear how much field data collection methods matter for predictive performance. To evaluate this, we used maize yield esti

Highlights • We examine inter- and intra-plot heterogeneity of productivity in maize plots. • We find high inter- and intra-plot variabilities in plant population and yield. • Intra-plot heterogeneity overrides inter-plot heterogeneity in small

Highlights • The accuracy of farmer’s elicitation and miniaturized spectrometers is assessed in rural Ethiopia. • Farmer’s elicitation do not converge with objective metrics. • Miniaturized spectrometers provide accurate data for the identi

Highlights • Following a strong El-Niño, some regions of Ethiopia experienced major droughts during the 2015/16 agricultural season. • This study investigates the effect of terraces and contour bunds on yields during the 2015 drought. • At the

Highlights • Accurate measures of yield are essential for evaluating agricultural productivity. • Substantial heterogeneity in yield estimation protocols has received little critical attention. • Alternative protocols differ widely in yield est

Accurate crop varietal identification is the backbone of any high-quality assessment of outcomes and impacts. Sweetpotato (Ipomoea batatas) varieties have important nutritional differences, and there is a strong interest to identify nutritionally sup
