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

The lack of reference price information is often regarded as one of the most pervasive aspects of incomplete commodity markets in developing countries. Previous studies on the effects of price information emphasize the market participation and perfor

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

Smallholder farmers in Africa typically only have access to blanket fertilizer recommendations which are defined over very broad areas and may not be optimal for local production conditions. The response to such recommendations has generally been poo

The aim of this paper is to study the association between weather shocks (droughts and floods) and agricultural market performance in Mozambique. To do so, we employ a dyadic regression analysis on monthly maize prices, transport costs, and spatial i

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
