Abstract
Uses of wastewater in agriculture are a viable option in solving water scarcity, food security and improving environmental hygiene. Vegetable being a good source of plant protein, fat and carbohydrates is not readily available round the year due to shortage of irrigation water. Effect of wastewater irrigation on the macronutrients contents of Celosia argentea vegetable was investigated. Three wastewater types (laundry/bathroom, BW, abattoir wastewater, AW and cassava effluent, CE) were used to grow the vegetable in potted experiment. The vegetable was also grown with rainwater to serve as a control. Harvested vegetable from the different wastewater treatments were analyzed for their macronutrient contents. The Analysis of variance (ANOVA) of the results was performed at a confidence level of 95 % (p < 0.05), and the mean was separated using DMRT in Statistical Package for Social Sciences (SPSS). Analyses revealed that protein content of the vegetable decrease in the order BW (18.03%) > AW (15.64%) > CE (8.68%) > RW (8.52%). The fat content was in the order AW (6.27%) > BW (5.95%)> CE (4.72%) > RW (4.22%). The effect of different wastewater used was not significantly different on carbohydrate content of the plant which is between 24.9 and 26.0%. The effect of the treatments on the moisture content of plant was found not to be significantly different from the control (p< 0.05) (AW (11.24%); BLW (11.01); CE (11.23) and RW (11.23)).
The results of the experiments show that irrigating with wastewater improves the macro nutrients of Celosia argentea vegetable. It however recommended that more works be done on wastewater effect on other proximate values of the vegetables.
