Abstract:


Soils from Ikorodu (Orthic Luvisol) and Lagos
State University (LASU) Ojo campus (Dystric Fluvisol) were
used in greenhouse experiments to determine N, P and K
requirement of
Amaranthus cruentus L. using five
rates of NPK 15:15:15 at 0, 150, 300, 450 and 600 kg ha1.
The experiment was arranged in a completely randomized
design with four replications. Soil treated with 300 and 450
kg ha-1 NPK 15:15:15 significantly (p<0.05) enhanced plant
height number of leaves shoot fresh and dry weight and plant
N-uptake compared to other treatments at Ikorodu.
Corresponding values were obtained from soil treated with
450 and 600 kg ha-I NPK 15:15:15 at LASU. Optimum N, P and K
requirements for A. cruentus at Ikorodu and LASU were 45.0
and 67.5 kg N/ha-1 respectively.

 
Key words: Orthic luvisol, Dystric Fluvisol, soil, nutrient
uptake, yield.
