In a study on effect of seeding rate (15, 30 and 45 kg/ha) and nitrogen fertilizers rates (60, 120, 180 and 240 kg N/ha) on forage yield and quality of sorghum [Sorghum bicolor (L.) Moench] x sudangrass [Sorghum sudanense (Piper) Stapf] hybrid, seeding rates and nitrogen fertilization did not affect significantly the green forage (GF) yield at the first cutting. The highest green fodder yield (5.0.8 tonnes/ha) was obtained from 45 kg/ha seed rate at the second cutting. There was no significant effect of N fertilization on dry-matter yield at the first cutting. The highest dry-matter yield was obtained from 60 kg N/ha and 45 kg/ha seeding rate in the second cutting. The effect of seeding rate and N fertilization on crude protein content was not significant at the first cutting, but nitrogen rate had significant effect on it at the second cutting.
