Abstract

The study evaluated the quality of organic fertilizer on the different ratios of cow manure and laying hens manure. The study used a completely randomized design with five treatments, such as T0 (100% cow manure), T1 (75% cow manure and 25% laying hens manure), T2 (50%cow manure and 50% laying hens manure), T3 (25% cow manure and 75% laying hens manure) and T4 (100% laying hens manure). The parameters observed in this study contained nitrogen (N), phosphor (P), potash (K), carbon (C) organic, C/N ratio, and pH. The results showed the ratio of cow manure and laying hens manure had a significant effect (P<0.05) on the content of the N, P, K, C organic, and the C/N ratio, but no significant effect (P>0.05) on pH. The fertilizer with laying hens manure had the highest (P<0.05) contain N (1.57%), P (1.39%) and K (1.31%), but the lowest of the C/N (14.67%).
