Experiments during three rice croppings to determine the possibility of introducing a non-indigenous blue-green alga (BGA) in a soil already with an indigenous species showed that the indigenous BGA established its growth better than did the introduced species. Application of the BGA, either surface-applied or incorporated in soil, did not show any significant effect in the total yield of algae biomass. Orthophosphate in floodwater and total solar radiation showed significant positive relationships with algae biomass. Addition of urea fertilizer suppressed the growth of BGA. Maximum algal biomass was higher in the dry than in the wet season prior to maximum tillering of rice or at about 60 days after transplanting.
