It compares the gross margin (golden bars, representing variable costs only) and the net margin (turquoise bars, representing both variable and fixed costs) across the different crops. Overall, the figure indicates that summer grain production under irrigation in Limpopo and Northern Cape is profitable, except for soybeans. The figure also highlights that sorghum production in Limpopo and maize production in the Northern Cape is more profitable. INCOME AND PRODUCTION COST
