棉花是在马里科帕农业中心种植的，分三个氮肥水平和三个水位。水是通过每行下埋的滴灌支管来浇灌的。棉花产量不受氮素的影响，因为土壤中有足够的氮素可获得最高产量。滴灌水平分别为预计消耗量的0.6、0.95和1.2。低水分条件下产量显著降低，为0.6ET。在滴灌研究附近种植的沟灌棉花的产量与中等水分条件下滴灌的产量相似，为0.95ET。
Cotton was planted at the Maricopa Agricultural Center in plots with three rates of nitrogen (N) and three water levels. The water was applied through drip irrigation laterals buried under each row. Cotton yields were not affected by N because sufficient N was available in the soil for maximum yield. The drip irrigation levels were 0.6, 0.95 and 1.2 of the estimated consumptive use (ET). Yields were significantly lower with low water, 0.6 ET. Yields from furrow irrigated cotton planted adjacent to the drip study were similar to yields with drip irrigation at medium water, 0.95 ET.
