Field trials were conducted to determine the effect of algal biofertilizers(Aulosira fertilissimaandAnabaena doliolum), alone or in combination with different doses of N-fertilizer (0#x2013;120 kg N/ha) supplied as urea, on biomass yield and nutritive value of rice. All doses of N-fertilizer, together withA. fertilissimaorA. doliolum, significantly increased plant height, number of tillers/hill, root length, leaf length, chlorophyll content, number of panicles/hill, number of seeds/ear, seed weight, grain yield, protein, and N content of grain. However, lower doses of N-fertilizer resulted in more efficient and rapid responses. Maximal qualitative improvement in rice production was found with 90 kg N/ha together with 12.5 kg/ha algal biofertilizer. The responses to these biofertilizers appear to be strain-specific since application ofA. fertilissimayielded better results than application ofA. doliolum.Application of the former saved about 25 of the chemical N-demand of the crop.
