Under tropical soils, the precise requirement of inorganic fertilizer and its possible substitute is yet to be 
validated for the production of Amaranthus cruentus L. The nutrient requirement of A. cruentus under two  soil types and yield quality under field conditions. Field experiment was conducted at two locations in Lagos State: Ikorodu (Orthic Luvisol) and Lagos State (LASU) Ojo Campus (Dystric Fluvisol) to  investigate the  effects of organic and organomineral and NPK fertilizer treatments on the quality of Amaranthus  cruentus L. Eight fertilizer treatments. (1) Control (no fertilizer), (2) Pacesetter’s Grade B (PGB) 100 %, (3)  PGB + NPK (75:25), (4) PGB + NKP (50:50), (5) Kola Pod Husk (KPH) 100 %, (6) KPH + NPK (75:25), (7)  KPH + NPK (50:50) and (8) NPK (100 %) were tested at first planting. Residual effects of the fertilizers were  assessed in the second and third planting periods. The experiment was arranged in a randomized complete  block design in four Replications. Parameters assessed include proximate analysis. Data were analysed using  ANOVA. The KPH + NPK (75:25)resulted in significant (p<0.05) higher crude protein content (19.8 and  14.9 %), ether extract (8.5 and 8.2 %) while crude fibre (9.5 and 10.8 %) was lower than control at Ikorodu  and LASU respectively. The KPH and PGB had high potential in A. cruentus production. At Ikorodu, KPH +  NPK (75:25) was the best while at LASU, PGB + NPK (75:25) was optimum. KPH + NPK (75:25) gave  highest crude protein content, ether extract and lowest crude fibre in A. cruentus.
