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 × 104 g-1, 32.07 to 82.03 × 104 g-1 and 31.03 to 74.47 × 104 g-1 soil at 30, 60 and 90 days of transplantation of rice seedlings respectively. The highest and lowest values were encountered in N50P50 and N100P0 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
