Cotton producers in the United States have made continued attempts to grow the crop on various row spacing and row configurations. Configurations used include double rows on beds ranging from 6 inches to 14 inches and single rows ranging from 19 inches to 40 inches. Narrow row cotton culture has increased about ten-fold during the past 20 years. Most narrow row cotton currently consists of 30 inch, 32 inch, and some 36 inch systems. Increased yields is the most common rationale for narrow row cotton, but convenience of growing it with other crops which lend themselves to 30 or 32 inch rows in also important. Other benefits reported include water savings, earliness, better response to the growth regulator pix, improved lint quality, fewer pesticide applications, and better use of solar radiation.
