The purpose of the study was to examine the effects of industrial and municipal liquid wastesrnon the growth (leaf number, leaf length, and leaf width), biomass productivity and plant tissuerncomposition of three different vegetable species. Furthermore, the study attempted to detect therntoxicity symptoms and concentration of some of the heavy metals (Cd, Cr, Cu, Ni, Pb, and Zn)rnon the vegetables as a result of the treatment.rnThree different vegetable species Beta vulgaris var. cic/a (swiss chard), Lactllca sativarn(lettuce) and Brassica oleracea var. capitata (cabbage) were allowed to grow under threerndifferent treatments, i.e., tap water(control), industrial and municipal liquid wastesrn(experimental). Fluvial soil, which was free from industrial and municipal liquid wastes wasrnsample, for experiment. Industrial and municipal liquid wastes were brought from Akaki textilernfactory and Bulbulla river respectively.rnThe experiment was conducted under glasshouse condition. The growth parameters of thernvegetable species were recorded at every seven days interval. Plant material analysis has beenrnadministered at two stages, after the 6th week and during harvest. The descriptive statistics, andrnanalysis of variance were applied to analyze the effect of the treatments on the vegetablernspecies. The physical and chemical properties and concentrations of heavy metals in the soilrnsamples were determined using laboratory analysis. The concentrations of heavy metals werernanalyzed using atomic absorption spectrophotometer (AAS).rnThe result showed that vegetables treated with municipal liquid waste exhibited a relative betterrngrowth in leaf number, leaf length, leaf width and shoot biomass productivity than the otherrntwo treatments. Similarly, the distribution of total organic carbon, organic matter, totalrnnitrogen, available phosphorus, exchangeable bases, soil pH and CEC were observed to bernsignificantly high in the soil samples treated with the municipal liquid waste than tap water andrnindustrial liquid waste treated soils.rnIn addition, the leaf number, leaf length, leaf width and dry matter yield of vegetables treatedrnwith municipal liquid waste were found to have a positive and significant correlation with soilrntotal organic matter, total organic carbon, organic matter, total nitrogen, available phosphorusrnand exchangeable bases. Yet, except for Cd, and Pb, an increase in the concentration of somernof the heavy metals (Cr, Cu, Ni, Zn) was observed on the analyzed soil samples treated withrnboth industrial and municipal liquid wastes. On the other hand, however, the research findingsrnindicated that the difference in the level of concentration (accumulation! of heavy metals as arnresult of industrial and municipal liquid wastes application, between the sampled vegetablernspecies was insignificant for Cd, Ni, and Zn. However, the concentration difference for Cr, Curnand Pb within and between the vegetables was significant. In the study, neither toxicityrnsymptoms nor reduction of yields in biomass was observed in all sample vegetables.rnFurthermore, from the findings it was observed that the degree of concentration of heavyrnmetals in each of the sampled vegetables was below the range of toxicity level.
