Abstract

Soil fertility is one of the limiting factors for sweet corn crops. To overcome it, the wise use of fertilizer is a must to maintain long soil sustainability. Our previous study showed that a rhizobacteria consortium had a significant positive effect on crop growth and productivity; even the chemical NPK performed better. But a long and continuous chemical NPK used has been reported negatively impacting soil and the environment. Thus, combining the application of biofertilizer and chemical NPK could be a practical option. This study aims to isolate bacteria from the sweet corn crop rhizosphere and use them as biofertilizer agents in dual application with NPK. The applied NPK doses were 25%, 50%, and 75% of the recommended dose, while mixed rhizobacteria was 16% of the total volume suspension containing 1.5% molasse. It found five pure rhizobacteria isolates, R1, R2, R3, R4, and R5, which could solubilize phosphate and potassium. It coincided as Burkholderia cepacian, Pantoea dispersa, Enterobacter cloacae, P. dispersa, and P. cypridii, respectively, based on the 16s RNA gene similarity. Application of mixed rhizobacteria dual with 50% and 75% of NPK showed apparent support for crop growth and productivity. Those supports were significantly similar to those performed after 100% NPK (control). This meant that by reducing chemical NPK and adding rhizobacteria, the growth and productivity of sweet corn crops could be maintained well as if 100% chemical NPK was applied.
