Abstract: This research was intended to determine the rate of organic soil treatment (OST) and the interval of Landeto solution application or their interaction on the growth of shallots grown on Regosol. This research was conducted in the green house of Department of Soil Science, Faculty of Agriculture Gadjah Mada University. A Randomized Complete Block Design, employing a factorial treatment was chosen. The first factor was rates of OST, i.e.: 0, 3, 6, 9 and 12 ton ha-1. The second factor was interval of application of Landeto Solution, i.e.: 3, 5 and 7 days. The combination treatments were repeated 3 times. Results of the research showed that: 1) the combination between rates of OST at 6 ton ha-1 and interval of application of Landeto solution at 5 days resulted highest values in leaf area, bulb number per hills, leaves number, and leaf area (32.03 cm, 10.07, 29.87, 384.80 cm2 respectively); 2) application of OST at 6 ton ha-1 had a significant effect on the plant height, the shoot-root ratio, the net assimilation rate; and 3) application of Landeto solution at different intervals had no significant effect on all growth components and crop yield.
