摘要：Introduction and objective. Water is one of the most important precious resources found on the earth, and are most oftenaffected by anthropogenic activities and by industry. Pollution caused by human beings and industries is a serious concernthroughout the world. Population growth, massive urbanization, rapid rate of industrialization and modern techniques inagriculture have accelerated water pollution and led to the gradual deterioration of its quality. A large quantity of wastewater disposed of at sea or on land has caused environmental problems which have led to environmental pollution,economic losses and chemical risks caused by the wastewater, and its impact on agriculture. However, waste water whichcontain nutrients and organic matter has possible advantages for agricultural purposes. Therefore, the presented studywas undertaken to assess the impact of Dairy Effluent (treated and untreated waste water) on seed germination, seedlinggrowth, dry matter production and the biochemical parameters of lady’s fingers (Abelmoschus esculentus L.).Materials and methods. A field experiment in a green house was conducted to use raw and treated dairy wastewaterfor watering lady’s fingers (Abelmoschus esculentus L.). The plants were watered using (WW) raw dairy wastewater, (T1)chemicals treatment, (T2) physical treatment, (T3) dilution method treatment and tap water (TW) in pot experiments. Tenplants of each treatment /3 replicate were randomly selected and labelled for the collection of data. The data was collectedsequentially, starting with chlorophyll content pre-harvest, vegetative qualities (shoot, root and seedling length) and drymatter quality (shoot and root dry matter) pos-tharvest.Results. The effect was seen on the germination seed and growth of the plant. The results showed inhibitory effect from dairyeffluent (WW) on seed germination and plant growth. Treatment with chemicals showed statistically significant differenceswith other treatments. Chemical treatment (TC2) at 20 mg/L Al2(SO4)3 and pH 6.5 improved all growth characteristics, comparedwith WW, and TW reached 85%, 70.8 cm, 28.6 cm, 99.4 cm, 65.36%, 15.86% and 3.543 Mg\g FW for seed germination, shootlength, root length, seedling length, shoot dry matter, root dry matter and chlorophyll, respectively. Also, 25% concentrationand 6.5 pH from the dilution method treatment improved all the qualities, but at a lower level. A maximum favourableeffect was also observed in the (T2) physical treatment, and ranged from average to moderate in terms of impact.Conclusions. Thus, dairy effluent, after chemical treatment and proper dilution, can be used as a potential source of waterfor seed germination and plant growth in agricultural practices
