The demand for shallot, as a national strategic commodity, is very high and increasing. <br /> <br /> This leads to an increase in the area of shallot harvest nationally. But the increase in <br /> <br /> harvested area is not accompanied by increased productivity. The main problem facing <br /> <br /> shallot farmers to improve productivity is the low availability of quality seeds and <br /> <br /> disease free. <br /> <br /> True Shallot Seed (TSS) derived from generative propagation or seed is an alternative <br /> <br /> to produce healthier seeds. TSS can be planted directly (direct seedling), through <br /> <br /> seedling, or through the production of mini tubers. <br /> <br /> Mini tuber production using PGPR (Plant Growth Promoting Rhizobacteria) plant with <br /> <br /> organic compost input can be used as one of environmentally friendly technology <br /> <br /> solution to increase the productivity of shallot. The study was conducted at screen <br /> <br /> house ITB Jatinangor using Completely Randomized Design (RAL) with four different <br /> <br /> PGPR concentration treatments and five replications. The data were analyzed using <br /> <br /> One Way Anova Analysis and if it was found to have a significant effect on further test <br /> <br /> using Duncan Multiple Range Test (DMRT) at &#945; = 5%. If the data is not normally <br /> <br /> distributed, Kruskal-Wallis analysis is used. <br /> <br /> The use of compost with different concentration of PGPR (Plant Growth Promoting <br /> <br /> Rhizobacteria) did not affect the growth and yield of shallot mini bulbs from TSS Tuk <br /> <br /> Tuk seed varieties. The concentration of PGPR (Plant Growth Promoting <br /> <br /> Rhizobacteria) 0 g / L (without PGPR), 5 g / L, 10 g / L, and 15 g / L with a dose of 20 <br /> <br /> ton / ha compost produced healthy growth with equally good yields resulting in average <br /> <br /> yield of dry bulbs that fit the optimal mini bulb criteria, ie weighted 2-5 grams and 1-2 <br /> <br /> cm diameter. However, there is a tendency that the compost dosage and PGPR (Plant <br /> <br /> Growth Promoting Rhizobacteria) with a concentration of 5 g / L potentially provide <br /> <br /> the best shallot mini tubers yield
