GROWTH, YIELD AND ABSORPTION OF CARBONDIOXIDE (CO2) POTENTIAL DAYAK ONION (Eleuteherine americana Merr) ON PEAT SOIL

The purpose of this study was to determine the growth, yield and potential for carbondioxide absorption dayak onion plants given four types manure on peat soil. This experiment used a completely randomized design with treatments six replications. tried were chicken, swallow, cow, goat manure. results showed that type had an effect plant growth yield. height number leaves planted soil cow grew significantly higher more leaves, lowest found in fed swallow highest obtained fertilized 30 t ha-1 tuber weight 41.50 g clump-1, larger diameter, but tubers by diameter smaller. biomass, stored carbon dioxide 6.6; 3.3 12.11
