摘要：Assessment of cyanobacterial population in saline soil amended with three rates of each of N (0, 50, 100 kg ha -1 ) and P (0, 25, 50 kg ha -1 ) fertilizers in a factorial combination showed a significant variation during growth of rice. Quantitatively the population of cyanobacteria ranged from 26.90 to 70.83 × 10 4 g-1, 32.07 to 82.03 × 10 4 g -1 and 31.03 to 74.47 × 10 4 g -1 soil at 30, 60 and 90 days of transplantation of rice seedlings respectively. The highest and lowest values were encountered in N 50 P 50 and N 100 P 0 treatments respectively irrespective of the sampling intervals. Addition of P accentuated the proliferation of cyanobacteria while that of N inhibited their abundance significantly with increasing level of the applied fertilizers. Joint contribution of P and N stimulated significantly better growth of cyanobacteria. DOI: http://dx.doi.org/10.3329/jasbs.v39i2.17852 J. Asiat. Soc. Bangladesh, Sci. 39(2): 167-171, December 2013
