Investigating the Effects of Bioslurries on Some Agronomic Properties of Common Vegetablesrius

Blessing Funmbi Sasanya

The increasing costs, dwindling supply, and the environmental effects associated with the uses of petroleum products call for attention. It is, therefore, appropriate to look out for environmentally sustainable alternatives to inorganic fertilizers which have direct links to agricultural production and sustainable food supply. The aim of this study is to investigate the potency of digested organic manure (bioslurry) for the production of common vegetables. Six growth parameters of two vegetable types- Amanranthus hybridus and Corchorus olitorius were investigated on five soil treatments in three replicates. The wastes and soil samples were also analyzed before and after the experiments. At 95% level of confidence, the soil amendments had no significant difference in the plant's heights, root lengths, Leaf Area Index, an Average number of leaves and fresh plant weight since 6.39>F=1.50,1.00,0.59,0.69 and 0.36 respectively, 14 days after planting. The same trend was noticed for 21 and 28 days measurements since 6.39>F=1.02,2.59,0.51,0.55 and 0.83 respectively for 21 days measurements. However, there are significant differences between the two plant types for the parameters measured. Duncan Multiple Range Test (DMRT) more often than not revealed better performances of poultry bio-slurry. Bio-slurry can thus serve as good replacements for inorganic fertilizers for the production of common Nigerian Vegetables.
