ABSTRACT: The study investigate the abundance of phytoplankton in Glagah District. The objective was of the research to explore the relation of the nitrate and phosphate nutrients to the abundance of phytoplankton in the area. The study conducted on July to Agust 2014. The "brucin”methodwas utilized to analyzed the nitrate and "the stano cloride”todetermine the methodphosphate.The phytoplankton sampling applied the purposive sampling method to choose five observation stations. The results showed that there were 25 genera from 4 classes of phytoplankton which consists of Chrysophyceae (9 genera), Bacillariopyceae (7 genera), Dinophyceae (5 genera) and Chlorophyceae (4 genera). The nitrate content value was about 0.176-0.598 mg/L, mean while the phosphate content value was about 0.016-0.028 mg/L. The determination index was generated from the pearson product moment correlation was about 38.3% (psig< 0.05) showed that there was the sufficient correlation between nitrate nutrient and the abundance of phytoplankton, and 2% (psig>0,05) showed that there was the very weak correlation between phosphate nutrient and the abundance of phytoplankton.
