Corn and Soybeans in a Strip Intercropping System: Crop Growth Rates, Radiation Interception, and Grain Yield Components

Table 1

PAR interception (IPAR) (Mj m⁻²). Locations 1, 7, or 12, corresponds to the northern, central, and southern rows, respectively. In monoculture, measurements were made in the center of the plot. Means in a column followed by same letter are not significantly different (𝑃<0.05).
