Iju/itaogbolu,
Akure North Local Government Area, Ondo State, Nigeria (Department of Agriculture,
Ondo State, Nigeria) |
Variety: Amaranthus
cruentus
Planting
date: late season of 2000
Soil
type: unknown
Replications:
three |
Vitazyme
application: a seed treatment only with 5% Vitazyme, air dried
before planting |
Vitazyme application significantly improved
plant height, leaf number per plant, leaf area per plant, and fresh shoot weight above
the control treatment. [No data is available.]
Comments:
Vitazyme applied to the amaranthus
seeds only before planting produced significant growth stimulation effects throughout
the 6-week growing period. Especially noticeable was the effect of Vitazyme
to initiate more efficient fertilizer utilization, making plant height, leaf number,
leaf area, shoot weight, and plant biomass as great with the 100 kg/ha NPK level as
with the 200 kg/ha NPK treatment with no Vitazyme. This effect of encouraging
more efficient nutrient use is especially important for countries such as Nigeria
where nutrient applications, because of high costs, may be suboptimal, but where Vitazyme
can increase fertilizer effectiveness so the farmer can approach optimum yields in
spite of this reduced application rate.
