EFFECTS OF MEAT PRODUCT WASTEWATER ON SEED GERMINATION OF RD 41 RICE (ORYZA SATIVA L.) FOR REUSE PURPOSER. PATSINGHASANEE, P. DHANMANONDA, S. BUALERT, O. PHEWNIL AND D. ONWIMOL
Meat product wastewater was investigated for the effects on seed germination of RD 41 rice seeds (Oryza sativa L.) due to its high quantity and possibility to reuse and mitigate water shortage situation. The wastewater with pH 7.66, EC 722 mS/cm, COD 960 mg/L diluted by deionized water to 0, 12.5, 25, 50, and 100 %, and 10, 20, 30, 40, 50, and 60 % concentrations by volume were applied to germinate 50 rice seeds by a between paper method for 5 days at 5 replicated. The germination percentage, total length, seed vigor index, wet weight/seedling, dry weight/seedling, and the mean germination time (MGT) of radical emergence were investigated. The significantly different of shorter MGT of radical emergence results for 10, 20, and 30 % concentration illustrated the better germination environment, therefore, 30% concentration was suitable to seed germination due to the highest quantity of wastewater to be reused.
