The Variable-Rate Decision for Multiple Inputs with Multiple Management Zones

By James A. Larson, Burton C. English and Roland K. Roberts

Abstract

Research has evaluated the relative profitability of variable-rate versus uniform-rate application of a single input in fields with multiple management zones. This paper addresses the variable-rate decision for multiple inputs. The decision-making framework is evaluated for nitrogen and water applied to irrigated cotton in fields with three management zones.Crop Production/Industries,
