Abstract              In a field experiment, proso millet was grown under irrigation in early
                      summer (May-June,1983) and received eight levels of urea-N applied
                      before seeding. The application of 50 kg/ha N raised yield of fresh forage
                      from 16.4 to 33.5 tons/ha. Higher N applications up to 250 kg/ha did not
                      further increase this yield though applications at 300 and 350 kg/ha urea-N
                      reduced yield causing in sever toxicity to seedling. Although the N content
                      of the forage related well to rate of N application, it was remarkably
                      affected by the growth stage. At near maturity the N content fell to below
                      0.7% . Low recovery of the applied N from the soil indicated heavy losses
                      probably due to NH3 volatilization. The depth of soil sampling to coincide
                      with root nutrient uptake distribution need further investigation.
