Abstract

The need to improve soil productivity and elimination of wastewater pollution potential to the soil can be greatly achieved through the application of wastewater from the fish pond. This study evaluates the effect of irrigation with effluent from fish pond on the soil, growth rate and also on the yield of maize and okra. The application of wastewater from fish pond through surface irrigation system improves the physico-chemical properties of the soil in terms of soil electrical conductivity, total soil nitrogen, total organic carbon, total organic matter, soil minerals, exchangeable acidity, cation exchangeable acidity capacity. The statistical analysis shows significance influence of wastewater application on all these physico-chemical properties to the soil at P < 0.05 while, the non-significance effect was observed for zinc and iron among the heavy metals investigated. This can be strongly attributed to the low quantity of such metals and their duration in the soil. The performance of maize and okra plants parameters were greatly influenced by the application of wastewater from fish pond. The result of the experiment shows that the plant height, number of leave, leave area and cob weight, yield of maize, and okra yield performs better when compared with the control plot of maize and okra plot respectively. From (Tables 3 and 4) which show the influence of wastewater application on plant parameters gave the highest yield of 5.39 tone/ha for maize through the application of wastewater from fish pond and the lowest yield of 1.04 tone/ha for the control plot which was irrigated with underground water also for okra the same trend was observed, the highest yield of 0.35 tone/ha was obtained from the plot irrigated with wastewater and the lowest yield of 0.15 tone/ha was obtained from control plot. From these results obtained the application of wastewater from fish pond to the soil was found to be satisfactory to improve soil physical-chemical properties as well as yield of maize and okra respectively in the study area.
