The aim of this research was to determine the effect of abattoir wastewater on the growth and yield of tomato plants. The Physicochemical properties of the wastewater such as colour, odour, PH, Total Dissolved Solid (TDS), temperature, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) and heavy metals were determined using standard analytical procedure. It was found that most of the physicochemical parameters were within the permissible limit stipulated by the World Health Organization (WHO, 1996). A pot experiment was conducted in the botanical garden of the Federal University Dutse. Tomato seeds obtained from JASCO were sown and transplanted into experimental pots with each of the pots watered with different concentrations of Dutse abattoir wastewater. The abattoir wastewater was prepared in the following concentrations (0ml of DAWW +23kg of soil =0%), (200ml of DAWW +23kg of soil =25%), (400ml of DAWW +23kg of soil =50%), (600ml of DAWW +23kg of soil =75%) and (800ml of DAWW +23kg of soil =100%) while distilled water was used as control, the experiment were carried out in complete randomized design with three replications. Statistical analysis using ANOVA revealed that the plant height, number of leaves, flowers and fruits differed significantly (p<0.05) compared to control. It was found that the growth and yield were concentrations dependent in all the weeks after transplanting. Highest growth and yield were observed in tomato plants treated with 800ml (100%) of abattoir wastewater. Abattoir wastewater from Dutse can be utilized for irrigation at best concentration of 100%.
