Abstract
The productivity of upland rice is still low as compared to that of irrigated rice. A cultivation effort needs to be done to increase productivity. One effort can be made by providing additional biostimulants to promote growth and beneficial bacteria. The study was conducted to determine the effect of some biostimulants on the root and population of phosphate solubilizing bacteria in upland rice (Situ Patenggang varieties). The tested treatment was a combination of biostimulants derived from seaweed, humic acid, and organic compounds. Each treatment was repeated 5 times. Parameters observed were the length and weight root, pH analysis, phosphate and C-organic levels in the soil and population of phosphate solubilizing bacteria. The results showed that the combination of biostimulant gave significant effect on plant growth parameters. The combination of a humic acid with seaweed extract gave the highest length and weight root. Humic acid also has a significant effect on the total population of phosphate solubilizing bacteria. The total population of phosphate solubilizing increased up to 150,000 cfu/mg.
