                                Technical Abstract: A study to evaluate the response of Deltapine 555 BG/RR at three different row patterns (one planted:one skipped, two planted:one skipped, and solid) and three specific plant spacings (3, 6, and 12 inches between plants) was conducted at the Mississippi State University Plant Science Farm in 2003 and 2004. At maturity, boll samples were hand harvested from all plots for analysis of boll size and lint percent.  Boll size was greater in the 12" plant spacing and 1:1 row pattern compared to the other treatments. Lint percent was affected by all row patterns. Lint percent for the solid, 2:1, and 1:1 was 47.44, 46.78, and 46.0, respectively. Yield data suggests that plant spacing exhibits essentially no effect on seedcotton or lint yield; whereas row pattern had a significant impact on lint yield A ̄1. Lint yield for 1:1, 2:1, and solid were 1318, 1383, and 1474 lbs A ̄1, respectively. These yields are based on a land acre basis. Plants were box mapped before harvest to determine the distribution of yield over the plant. The plant spacing had no effect on overall yield, but had a significant effect on the distribution. The amount of lint produced by vegetative nodes increased significantly with each increase in plant spacing. A higher percentage of yield produced by vegetative nodes will have management implications.
