Abstract
The application of organic and inorganic fertilizers to the soil is considered as good agricultural
practice because they improve the fertility of the soil and plant quality. The overall objective of the study is to compare
the effects of organic fertilizers (cow dung and chicken droppings) with inorganic fertilizer (urea) on the vegetative
growth of Amaranthus dubius. The data obtained showed that, levels of all parameters measured for both the organic
and inorganic fertilizers ranges; Stem length (7.5- 64.2) cm, Stem width (2.4- 8.1) cm, Leaf length (8.0- 19.3) cm, Leaf
width (3.3- 14.2) cm and Number of leaves per plant (09- 34). The mean values for the stem length, stem width, leaf
length, leaf width and number of leaves per plant were evaluated and found to be higher in plants grown with urea
treatment compared to values obtained from the treatments with organic manures. Data were analyzed using One-way
Analysis of Variance (ANOVA) and the results were expressed as percentage difference, the differences between the
mean values were determined at 95% confidence. Inorganic fertilizer resulted in significant effects at (p<0.05)
compared to values obtained from the organic manures.
