Resumo: 	Farmers are interested in knowing whether applying inputs at variable rates across a field is economically viable.  The answer depends on the crop, the input, their prices, the cost of variable rate technology (VRT) versus uninform rate technology (URT), and the spatial and yield response variability within each field.  Methods were investigated for determining the range of spatial variability over which the return to VRT covers its additional cost compared with URT in fields with multiple management zones.  Models developed in this article, or variants thereof, could be used to help farmers make the VRT adoption decision.
