Abstract
This study was carried out to determine the effect of chemical fertilizer and two fermented types of pig slurry on the dry matter(DM) yield of three crops and chemical properties. The experiment design was a split plot with three replications. Main plots consist of three crops : $sorghum{\times}sudangrass$ hybrid('SS405'), sudangrass('Jumbo'), corn('DK501'). Sub plots consist of three treatments : chemical fertilizer (CF N-200, P-150, K-150 kg/ha), aerobic fermented pig slurry (APS 200kg N/ha), and aerobic fermented pig slurry treated with probiotics (APS+P 200 kg N/ha). Plant heights with three crops per sudangrass (380.3cm) was the longest (p<0.01). Dry matter yield of aerobic fermented pig slurry treated with probiotics was the highest the other treatments (p<0.01). Crude protein (CP) content were highest in $sorghum{\times}sudangrass$ hybrid than in the other crops. Cupper content(%) were highest in aerobic fermented pig slurry treated with probiotics than in the other treatments.
