The author offers guidelines in canopy management. He suggests that canopies should be large enough to get most available light but not over-large as it causes increased lodging and poor penetration of light to lower pods. The principles of achieving the ideal canopy are discussed. Building a canopy depends on careful management of nitrogen and plant growth regulator (PGR), with a goal to achieve green area index (GAI) of 3.5 at mid-flower.
