Summary

Nitrogen fertilizer requirements and potential forage yield of maize and two millet types grown under irrigation in Saudi Arabia were assessed. Nitrogen application at 50 kg/ha produced mean yields of up to 15.7 t/ha in maize variety Pioneer H.3147. Splitting the nitrogen application did not significantly affect yield. Nitrogen above 100 kg/ha did not significantly increase DM yield of Proso millet (Panicum miliaceum). Mean total DM yields of 17.6 t/ha of Setaria italica were produced, after 111 days, with 150–200 kg/ha of nitrogen; 150 kg/ha of P2O5 produced a mean DM yield 7.9% higher than 75 kg P2O5/ha.
