Abstract

Among all treatments pots without growing rice plants containing N. muscorum showed the highest amount of mineral-N and P. boryanum was the lowest. On the contrary, treatments with rice plants containing all BGA species the amounts of NH4-N and NO3-N remaining were more or less equal to the fertilizers treatments. Among BGA species and fertilizers the highest amount of NH4-N and NO3-N were found at the 90 mg N pot-1 with urea and ammonium sulphate and A. doliolum gave the highest amount in comparison to other four species.

Key words: Mineral-N, Nitrification, Denitrificatoin, Bluegreen algae, Rice yield.
