The nursery experiment was conducted to observe influence of microbial fertilizers on growth of oil palm seedlings for two consecutive years. Azotobacter chroococcum, Azospirillum brasilense, Bacillus megaterium, Frateuria aurantia and Glomus aggregatum were the microbial fertilizers used individually, combindly and integrated with chemical fertilizers. All the treatments were found markedly superior to the control with respect to morphological and growth characters of oil palm seedlings. Among the treatments, most convincing and highly significant results for seedling height (78.87cm), number of leaves (12.33), leaflets/leaf (52.08), leaf area (1391cm2), stem girth (16.62cm), number of primary roots (17.45), root volume (186.58 cc), net photosynthetic rate (13.85µmol m-2 s-1), total chlorophyll (1.63mg g-1) and dry matter (200.53g) recorded under integrated application of microbial fertilizers + 25% recommended dose of fertilizers. Among individual microbial fertilizers, Glomus aggregatum showed outstanding performance which was better than 100% RDF and it was equally effective when compared with combined use of microbial fertilizers in most of the growth parameters. Results of the study indicated that minimal dose of chemical fertilizers is required for exploiting the best possible benefits from microbial fertilizers. Based on excellent performance, integrated use of microbial fertilizers with 25% of recommended dose of chemical fertilizers is recommended for commercial application in oil palm nurseries in India.
