The variety of raw materials for making liquid compost will certainly affect nutrient content and useful microbial content. This study was aimed to examine the effect of compost tea from various compost sources enriched with biological agents to improve the growth and yield of rice plants that are cultivated organically. This study used Randomized Complete Block Design with 10 treatments and repeated three times. The treatments tried included p<sub>0</sub>: control; p<sub>1</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from cow compost; p<sub>2</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from chicken coop compost; p<sub>3</sub>: liquid compost from mushroom waste; p<sub>4</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from cow compost + <em style="mso-bidi-font-style: normal;">Pseudomonas flouresence</em>; p<sub>5</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from compost chicken coop + <em style="mso-bidi-font-style: normal;">Pseudomonas flouresence</em>; p<sub>6</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from waste mushroom + <em style="mso-bidi-font-style: normal;">Pseudomonas flouresence</em>; p<sub>7</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from cow compost + <em style="mso-bidi-font-style: normal;">Trichoderma harzianum</em>; p<sub>8</sub>: compost tea from chicken coop compost + <em style="mso-bidi-font-style: normal;">Trichoderma harzianum</em>; p<sub>9</sub>: <span style="mso-spacerun: yes;"> </span>liquid compost from waste of mushroom + <em style="mso-bidi-font-style: normal;">Trichoderma harzianum</em>. The variables observed included plant height, number of tillers, leaf greenness, leaf area, LAI, number of productive tillers, panicle length, number of seeds per panicle, percentage of filled grain, and grain yield. The results showed that the application of <span style="mso-spacerun: yes;"> </span>liquid compost enriched with useful microorganisms had not shown its effect in increasing the growth and yield of Sintanur variety in organic cultivation. The highest yield were achieved in the treatment of liquid compost from baglog mushroom enriched with <em style="mso-bidi-font-style: normal;">Trichoderma harzianum</em> at 3.06 tons ha<sup>-1</sup>.</span>
