Production of Maize on Subsistence and Underutilised Farmland

Data was derived from the following sources: * Extent of underutilised and subsistence farmland, data obtained from Department of Agriculture, Forestry, and Fisheries. * On such land, maize potential was calculated from data published by Schulze (2007) on maize-growing potential. * Grain, Oil, and Residue (Stover) production was calculated based on grain yields, and aggregated to meso-zones for planning and feasibility analysis. * Grain, Oil and Residue ratios were derived from literature. * Exploitable fraction of residue was reported based on assessment of yields and published literature
