Biomass Increment (T/Ha/An) per 100 mm Gross Irrigation Schedule: 15 mm Net, 7 Day Cycle

This dataset contains the yield increment with irrigation in South Africa, which is defined in this Atlas as (Irrigated Yield - Dryland Yield) / (100 mmGross Irrigation Demand). In light of increasing costs of irrigation water, which may vary from region to region according to its availability/scarcity, and the role played in irrigation scheduling by naturally occurring rainfall, yield increases need to be expressed with respect to the amount of irrigation water required by the plant for maximum yield over and above the natural rainfall utilised by the plant.
