Sažetak
The macronutrient uptake of A. cruentus under two soil types: Ikorodu (orthic Luvisol)
and Lagos state university LASU) Ojo campus, (Dystric Fluvisol) were investigated
under field conditions. Eight fertilizer treatments (1) control (no fertilizer), (2)
pacesetter’s Grade B (PGB) 100%, (3) PGB + NPK (75:25), (4) PGB + NPK (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. Data were analyzed using
ANOVA Test. Due to the high N status of the soil in Ikorodu (sandy clay loam) its
uptake was significantly (p<0.05) higher (87.1%) than that of LASU. The KPH and
PGB had the highest potential in A. cruentus production. At Ikorodu site, KPH + NPK
(75:25) had the nutrient uptake while at LASU, PGB + NPK (75:25) was optimum.
KPH + NPK (75:25) gave highest N, P, K, Ca and Mg uptake in A. cruentus
