โฆ Synopsis
Components of the radiation and energy balance are described and related to the growth, physiology, and structure of crop canopies. The net radiation below the canopy is used to evaluate inter-row advection in narrow-row and wide-row sorghum.
The light environment in crops is discussed with respect to the reflective properties of plant leaves and the soil surface. A simplified model to predict the intercepted photosynthetically active radiation for a sorghum canopy is presented. When the light model is applied to narrow-and wide-row sorghum, the plants in the narrow-row spacing intercepted more light and predicted an 11.6% increase in net photosynthesis over the wide-row sorghum.
