A field experiment was conducted to observe the effect of residual phosphorus on the yield and quality of sorghum fodder in three soils i.e. Loamy sand (Torripsamment), clay loam (Ustochrept) and sandy clay loam (Haplargid). Different quantities of residual P in different soils significantly improved the fresh yield (t ha-1) and quality traits like dry matter content, P concentration in plant, crude protein and crude fiber content (%) in sorghum fodder. Maximum fodder yield of 36, 45 and 37 t ha-1 was obtained where residual P was 26, 33 and 31 mg P kg-1 in sandy loam, clay loam and sandy clay loam soils, respectively. After the harvest of sorghum fodder, still adequate quantity of residual P was there in all the soils.
