Five cotton cultivars were conventionally planted in rows spaced 76 cm and 102 cm and were no-tilled in rows spaced 76 cm apart. Seedling emergence was not influenced by rows spacing or tillage. Plant height was significantly reduced in rows 76 cm apart and by no-tillage. PIX(TM) (mepiquat chloride) reduced plant height In all instances.

Cultivars grown in rows spaced 76 cm were slightly earlier than cotton produced In rows 102 cm apart. Cultivar yield differences were observed at first harvest. Total lint yields were not influenced by cultivars, row spacing, tillage, or Pix(TM). No interactions were detected for any measured trait.
