A field experiment in green house was conduct to use raw and treated dairy wastewater for watering Abelmoschus esculentus L. (Ladyfinger). In the present study 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. The effect was seen on the germination seed and growth of the plant. The results showed inhibitory effect from dairy effluent (WW) on seed germination and growth plant. Chemicals treatment showed statistically significant differences with other treatments. Treatment (TC2) at 20 Mg/l Al2(SO4)3 and pH 6.5 is improved all growth characters compare with WW and TW reached to 85%, 70.8 cm, 28.6 cm, 99.4 cm, 65.36%, 15.86% and 3.543 Mg\g FW for seed germination, shoot length, root length, seedling length, shoot dry matter, root dry matter and chlorophyll respectively. Also concentration 25% and pH 6.5 from dilution method treatment was improved all the qualities but at a lower level. Also maximum favorable effect was observed to (T3) physical treatment ranged from average to moderate in terms of impact. Hence those effluents from dairy. Thus, the dairy effluent, after chemical treatments and proper dilutions can be used as a potential source of water for seed germination and plant growth in agricultural practices. |
