【 摘 要 】

The objective of this study was to determine the effect of the compost of spent mushrooms that was composted with different starting materials on the growth and performance of kangkong. This study was performed using a randomized block design, consisting of two factors. The first factor was the compost starter combination that consists of three levels (effective microorganism + CaCO3 effective microorganism + fertilizer of urea and phosphate). The second factor was the application dosages of compost that consists of 4 levels (5 tons/ha, 10 tons / ha, 15 tons/ha and 20 tons/ha). The results showed that the application of spent mushroom compost with diverse materials of initial compost starter showed a significant interaction in the width of the leaf at 10 days after planting (DAP), the height of the plant at 30 DAP, dry weight, and leaf area ratio at 20 DAP. In comparison with the controls, the significant influence occurred in plat height at 30 DAP, dry weight at 10 DAP, the width of the leaf at 10 and 20 DAP, and the ratio of the leaf area at 20 DAP. The combination of effective microorganisms + urea and effective microorganisms + phosphate fertilizer gave a good result in the growth and yield of kangkong.
