In 2005-06 we began investigations comparing the yield and maturity response of 38 cm (15') row spacings and conventionally spaced cotton while attempting to manage the two row spacings for Pix and nitrogen management separately. The 38 cm row spaced cotton did not need to be managed differently to the conventionally spaced crop in any of the three experiments for this season. In one of the three experiments the 38 cm spaced cotton had higher yield than conventionally spaced cotton. Research is continuing to understand how 38 cm row spaced cotton systems can be managed to give yield or maturity benefits.
