| dc.description.abstract | A greenhouse study comparing the application of Silicate (lemongrass
leaves and rice straw) versus Phosphate-Solubilizing Organisms (phosphate solubilizing bacteria and phosphate-solubilizing fungi) in reducing P retention
and its effects on corn plant growth in Andisol soil. This study used a Non Factorial Randomized Block Design (RBD) with treatments consisting of: control,
lemongrass leaf silicate (433,20 g/pot ), straw silicate (120,42 g/pot ), phosphate solubilizing bacteria (30 ml/pot), and phosphate-solubilizing fungi (30 ml/pot),
with each treatment combination replicated 5 times. The observed parameters
were soil pH (H2O), soil organic carbon, soil P-available, soil P retention, plant
height, dry weight of plant canopy, dry weight of plant roots, and plant P uptake.
The results of this study indicate that the application of lemongrass leaf silicate
and straw silicate are more effective than the application of phosphate solubilizing organisms in reducing P retention, increasing plant height, dry
weight of plant tops, dry weight of roots, and phosphorus uptake. The phosphate solubilizing bacteria were able to increase the available phosphorus in the soil
the most, followed by the treatment with silicate from lemongrass leaves, the
control group, phosphate-solubilizing fungi, and silicate from rice straw,
however, overall, these effects were not statistically significant | en_US |
