Inuence of feather meal on growth and yield of Amaranthus caudatus
Abstract
Inherent advantages of organic fertilizers are major factors making many farmers to consider their use in crop production systems. This has led to
evaluation of the inuence of feather meal on growth and yield of Amaranthus caudatus. The experiment involves both incubation study and
eld trials in two seasons. Completely Randomized Design was used for incubation study while Randomized Complete Block Design with four
replicates was used for eld trials. The treatments considered were feather meal, compost, mineral fertilizer (NPK 15-15-15) and control (no soil
additive). All the treatments (except control) were applied at 100 kg N/ha. The incubated treated soils were air dried and analysed for N. Data collected
from eld trials include growth parameters, fresh and dry yield. The data were subjected to Analysis of Variance (ANOVA) and means compared using
Duncan Multiple Range Test (DMRT) at 5 % probability level. The incubation study showed that feather meal had a higher release of N across the weeks of
incubation than NPK while control had the least. Results from the eld trials revealed that feather meal treatment (18 t/ha) at 4 weeks after sowing
signicantly (P<0.05) compared favourably with NPK 15-15-15 (20.21 t/ha) and compost (16.54 t/ha) while it resulted in better performances compared to
the control treatment (10.03 t/ha) on the fresh weight of amaranth plants during the dry season, while the rainy season trial followed the same pattern.
It could therefore be concluded that Feather meal is a good fertilizer for amaranth production.
