Abstract
Municipal waste water can be a source of nutrients in addition to meet the crop water requirements in
areas facing nutrient depression and water scarcity. Due to increased nutrient loss and water scarcity, use
of unconventional water sources for example waste water in Arable lands has now become important.
However, inclusive information on the effects of waste water on crop production and soil health is
necessary for such intervention. This study was designed to evaluate the effects by demonstrating the
contribution of waste water on the growth rate of maize (Zea mays).
Three application treatments of waste water were done 111 experiment 1, experiment 2, and control
experiment to determine the effects of waste water on the stem height, leaf length and number of leaves
of the maize plants. Experiments I, 2 and control were carried out with use of I 00% waste water, 70%
waste water and tape water respectively were used.
Three application treatments were done and tested in pots, where application of waste water was by
irrigation. Three applications were made, one week before planting, three weeks after germination and
six weeks after germination.
Plant height, leaf length and leaf number increased from applications of I 00% and 70% waste water over
the control treatment where tap water was applied. Although plant height, leaf length and leaf number
increased for both proportions of waste water, 70% waste water application contributed to maximum
plant height, leaf length and leaf number.
Municipal water could be used for biomass production of bioenergy crops and further studies are
required to test the composition of waste water before use and its impact on human through food chain.
