Three high-yielding and three low-yielding grain sorghum hybrids were grown for a full season for grain yield and total dry weight of forage with two levels of irrigation (dry and wet) and two levels of nitrogen (0 and 100 lbs /acre). The experiment was conducted at the University of Arizona Marana Agricultural Center. The combined high nitrogen fertilizer and high water irrigation increased grain yield and total dry matter of sorghum over the dry moisture condition and no nitrogen fertilizer application more than the applied increases of nitrogen fertilizer or irrigation water alone as expected. Both high- and low-yielding groups of sorghum hybrids had the same basic relative percentage potential for increased grain yield from additional nitrogen fertilizer under either wet or dry conditions.
