| Title : | COMPARISON BETWEEN SYNTHETIC CHEMICAL FERTILIZERS AND SOME BIOFERTILIZERS ON THE ROOT ENDOPHYTIC FUNGI AND RICE GROWTH |
| Abstract : | Rice (Oryza sativa) is the most consumed cereal in the world. However, the widespread use of synthetic chemical fertilizers in rice cultivation in Sri Lanka has compromised the sustainability of rice farming. A pot experiment was conducted to explore the impact of nitrogen-fixing bacteria; Azospirillum spp. and phosphorus-solubilizing bacteria Pseudomonas spp., Bacillus spp., and Trichoderma spp. based biofertilizers on the endophytic fungal population and rice growth. The fungal endophytes isolated from six treatments: T1: normal soil, T2: nitrogen-fixing Azospirillum spp., T3: phosphorus-solubilizing Pseudomonas spp., Bacillus spp.+rock phosphate, T4: Trichoderma spp., T5: Azospirillum spp.+Pseudomonas spp., + Bacillus spp.+Trichoderma spp.+ rock phosphate, T6: recommended dose of synthetic inorganic fertilizer. Aspergillus flavus, Aspergillus niger, Aspergillus spp., Penicillium spp., Fusarium spp., Trichoderma spp., and Bipolaris spp. were isolated as root endophytes. However, the statistical analysis using one-way ANOVA and the Tukey’s pairwise comparison test indicated that there was no significant difference in the diversity and abundance of root endophytes among the treatments (p>0.05). Furthermore, considering various biometric parameters of rice, including shoot length, root length, number of tillers per plant, flag leaf length, dry biomass, 100-grain weight, number of grains per panicle, and harvest index showed significant differences (p<0.05) when comparing the control and the respective treatments. Moreover, there were significant variations in soil nitrogen and phosphorus concentrations, pH, and conductivity among the treatments. This suggested that the development and use of such biofertilizers could be served as a sustainable alternative, reducing the reliance on synthetic chemical fertilizers in rice cultivation in Sri Lanka. |
