Soils from Ikorodu (Orthic
Luvisol) and Lagos State University (LASU) Ojo campus (Dystric
Fluvisol) were used in greenhouse experiments to determine
N, 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,
requirements for A. cruentus at Ikorodu and LASU were 45.0
and 67.5 kg N/ha-1 respectively.
