Abstract

The application of blue green algae and Azospirllum Significantly increased the total nitrogen content of rice grains . the highest increase (7.01%) over the control was observed in the treatment which received the bioinocula of imported algae strain and Azospirillum. The application of 20 and 40 kg N/fed, of urea led to highly sig­nificant increase in the total nitrogen content of rice grains. The highest increase (58.1 1%) over the control was observed in the treatment hav­ing 40Kg N/fed. The amino acids content of rice grains were also affected by bid­noculation and chemical fertilization. The inoculation with algea and Azospirillum and fertilization with 20 kg N/fed., Showed high amounts of both essential and nonessential amino acids in the grains.
