Abstract: In Ethiopia, huge amount of flower residues are generated in each flower farm and damped into the environment leading to various problems. This initiated this work to utilize the wastes for soil amelioration and protection of the environment by composting via mixing the flower cuts with cow dungs (Pile1) and Effective Microorganisms (EM) plus molasses (Pile2) using Windrow method of compostingseparately in Ethio-highland and ZK farms. Samples were regularly taken from three locations of each pile for pyhsico-chemical and microbiological analysis over the 98 days of composting. The data showed three phases of temperature shifts, increase in macronutrients and TN as well as GI but reduction in C: N and NH4-N: NO3-N ratios and elimination of Agrobacterium spp. in both farms, in pile 1 and pile 2. In composting better in cow dung amended than EM plusMolasses added. The final compost products were found to be good quality in terms of plant nutrient, heavy metal and microbial composition. The composting activity of the flower cut should be encouraged and continued using cow dung in different flower farms to overcome environmental problems and use as fertilizer to improve agricultural productivity.
