A field trial was carried out on seed production pattern of centro (Centrosema pubescens) in the year of establishment in a sub humid environment of Nigeria as influenced by sowing date and phosphorus application levels. The herbage residue and its crude protein content were also determined after pod harvest. The variation in seeds per pod for plantings between June 21 to August 2 was from 16.5 to 14.5, while for unfertilized and fertilized plots seeds number varied between 12.6 and 16.2 per pod. The weight of 1000 seeds decreased with delayed planting. Phosphorus application improved seed weight. Seed yield was highest (1000 kg per ha) for July 5 sowing with phosphorus application of 60 kg per ha P2O5 combination. The variation in mean seed yield for planting between June 21 and August 2 was 782.0 to 360.3 kg per ha. The application of 0 to 60 kg per ha P2O5 resulted in mean seed yields of 405.7 to 776.8 kg per ha. Herbage residue was favoured more by June 21 sowing and the application of 60 kg per ha P2O5. The crude protein content was better with August sowing and 60 kg per ha P2O5.
