The objective of this poster is to present results of a study aiming at optimizing irrigation and nitrogen use by a cotton crop grown with a Low Pressure System (LPS™). Drip lines were buried 6-7 inches deep under every row. Treatments consisted of nitrogen rates equivalent to 60, 90 and 120 lb N per acre injected weekly during 8 weeks, beginning at first square. Irrigation treatments consisted of 85% PET and 65% PET.
