Abstract
Productive tillering, grain and straw yields and N-contents of indica rice IR-28 were increased more by urea fertilizer at 48 or 96 kg N/ha along with Inoculation by cyanobacteria than by using 144 kg N/ha without inoculation. Fertilizer N-use efficiency was increased by the cyanobacteria and decreased with increasing amount of urea fertilizer. Further enhancement was obtained by soil application of calclum superphosphate at 36 kg P2O5/ha or sodium molybdate at 1 ppm Mo along with cyanobacteria and/or urea. Application of phosphate, however, slightly diminished the enhancement by molybdate.
