Growth Response of Corn to Nitrogen-Fixing Bacteria Enriched Compost

U.T. Pupathy and O. Radziah

Abstract:
Efforts are made to introduce strains of selected N-fixing bacteria; Bacillus subtilis and Bacillus licheniformis, as free living ‘asymbiotic N fixers’ into compost that made from Empty Fruit Bunches (EFB) and Palm Oil Mill Effluent (POME). A total of 7 soil treatments were established to evaluate the influence of N2-fixing bacteria-enriched compost on vegetative growth and performance of corn; 4 treatments of selected N2-fixing bacteria strains (namely BT28, BT29, BT30 and BT31) into compost meanwhile 1 treatment with nil inoculum and 2 treatments of control plots of 100% of inorganic fertilizer applications. All treatments were replicated 4 times and arranged in a randomized complete randomized design. The results showed that application of Bacillus sp. inoculated EFB compost significantly (p<0.05) increased total dry weight as compared to those plots applied with inorganic fertilizers. Growth of corn was significantly affected by the application of selected N2 fixing strains of Bacillus subtilis and Bacillus licheniformis particularly on the vegetative growth and performance of corn. Soil pH, nutrient concentration especially K and Mg were significantly increased due to presence of Bacillus sp. enriched EFB compost.
