Row Spacing
Row spacing is the second factor that determines canopy closure and yield components. Row spacing can either refer to the space between plants in the same row or the distance between two rows. Row spacing determines the degree of plant to plant competition. Rows planted closer together in a population will decrease the space between plants. Closer row widths increase plant to plant competition for nutrients and water but also increase sunlight use efficiency. According to former Iowa State University Soybean Extension Specialist Palle Pedersen, current recommendations are to plant rows that are less than 30” apart. This increases light interception and decreases weed competition.

Famous quotes containing the word row:
“When people ask me how I develop recipes, I have to respond: “travelling, eating, watching, experimenting, and constantly asking myself: ‘Do I want to eat this dish again?’” Will I yearn for it some evening when I’m hungry? Will I remember it in six months’ time? In a year? Five years from now?”
