This study was conducted to evaluate the effect of different fermented manure- sawdust composts(FMSC) application on Chinese cabbage growth in the field. Chinese cabbage was cultivated in sandy loam applied with 30t/ha of fermented pig manure-sawdust compost(FPMSC), fermented fowl manure-sawdust compost(FFMSC), fermented cattle manure-sawdust compostFCMSC) respectively, and control. The results obtained were as follows ; 1. FMSC treatments increased the Chinese cabbage yield by 31-41% while the decrease of N 120㎏/ha, P 100㎏/ha fertilizers compared to control. Effects of three FMSC on yield of Chinese cabbage were in the order of FPMSC>FFMSC>FCMSC. 2. Soil bulk density and hardness were decreased while OM, T-N, Mg, K in the soil were increased by FMSC after harvest. 3. Compare to three FMSC control or control+compost plot at 30day after transplanting soil NH4-N content was increased but at 60days after transplanting NH4-N content wasn't increased, and at harvest NH4-N content was decreased. Soil NO3-N content was increased from early growth to yield of Chinese cabbage. 4. Inorganic element absorption on 12th of November was increased by three FMSC. FPMSC treatment increased T-N absorption and FPMSC, FCMSC increased P2O5 absorption in Chinese cabbage more compared to different FMSC. Key words : Compost, Fermented Manure, Sawdust, Chinese cabbage.
