Effects of seeding rates and phosphorus levels on the productivity of Atylosia scarabeoides (Benth.)

Abstract
Glasshouse investigations were carried out to investigate the development and yield of Atylosia scarabeoides on soils of the northern guinea savanah zone of Nigeria. Seeds were sown at four rates 50, 75, 100 and 125 kg/ha. Single superphosphate (SSP) fertilizer was applied at sowing at four rates 0, 60, 90 and 120 kg/ha. Seeding (plant) population at one month and at harvest was significantly (p < 0.01) influenced by seeding rate but not fertilizer level. Fresh herbage yield was strongly (p < 0.01) dependent on fertilizer level, with the highest (not significant) dry matter yield at 90 kg SSP/ha. Seeding rate had no significant effects on herbage yield. The crude protein content of herbage rose with increase in fertilizer level although there were no significant differences between the various seeding and phosphorus rates. No significant interactions were observed between seeding rate and phosphorus lever. The yields were generally high, indicating good prospects for pasture development with A. scarabeoides in the zone, although field trials would be of benefit.
