Abstract:

The differential tolerance of Spinach (Spinaceae olearecea L) cultivars was examined for a period of five weeks (April-June) using different concentrations of waste water - majorly washed plate residues, collected from food vendors and restaurants within Keffi Metropolis of Nasarawa State. The parameters examined included the height and s of sprouted leaves of the cultivars after treatment with series of waste water Concentrations (WWC) (10%, 50%, and 100%), obtained as a percentage of the waste water diluted in a given volume of clean water. A Randomized Complete Block Design (RCDB) technique was used to set the experiment. Analysis of the results showed that waste water has some effects on the growth and development of Spinach Cultivars. This was shown by a mean coefficient of three percent (3%) increase in height from sixty five percent (65%) to sixty eight percent (68%) on days ten and twenty one respectively. Similarly the analysis of the sprouted leaves was found to be highly significant with an F. calculated value of 8.56 as against 3.38 value of the F. Tabulated at 5% d. f. The calculations on the Least Significant Difference (LSD) to deduce which treatment had a major influence over the others had the treatment designated M2 showing very high superiority over M1, followed by J1 and P1 respectively. Varying growth, small leaf size, yellowing of leaves and poor performance on cultivars were observed mostly in plots treated with higher concentrations of waste water. It is however necessary to imbibe the culture of waste water management for irrigation through appropriate guidelines and legislations by individuals, homes, communities and industrialist
