The stover biomass gap of a crop grown in a certain location and cropping system is defined as the difference between the stover biomass under optimum management and the average stover biomass achieved by farmers. Stover biomass under optimum management is labeled as potential biomass (Bp) under irrigated conditions or water-limited potential biomass (Bw) under rain-fed conditions.Bp is location specific because of the climate, and not dependent on soil properties assuming that the required water and nutrients are non-limiting and can be added through management. Thus, in areas without major soil constraints, Bp is the most relevant benchmark for irrigated systems. Whereas, for rain-fed crops, Bw, equivalent to water-limited potential biomass, is the most relevant benchmark. Both Bp and Bw are calculated for optimum planting dates, planting density and region-specific crop variety which is critical in determining the feasible growth duration, particularly in tropical climatic conditions where two or even three crops are produced each year on the same field. To increase food production, identifying the regions with untapped production capacity is of prime importance and can be achieved by quantitative and spatially explicit estimates of Biomass gaps, thus considering the spatial variation in environment and the production system.

The unit is Megagram per hectare (Mg ha-1) which is equivalent to tons ha-1. The climate data at the national scale was made available from the National Aeronautics and Space Administration (NASA), Goddard Institute of Space Studies(https://data.giss.nasa.gov/impacts/agmipcf/agmerra/), AgMERRA.The dataset is stored at 0.25°×0.25° horizontal resolution (~25km). Soil parameter values were extracted from the soil property maps of Africa at 1 km x 1 km resolution (http://www.isric.org/data/soil-property-maps-africa-1-km). Fertilizer application (Nitrogen and Phosphorus) rates over seven years (2004 - 2010) at administrative zone level have been collected from the Central Statistical Agency, Ethiopia.
