| Abstract | Mostly, contamination of Escherichia coli and Salmonella spp., always expose when using non-composted cow manure as organic fertilizer for growing vegetables, However, composting the manure for at least 98 days is enable to either decrease or decontaminate these microbes, This research was aimed to compare the contamination of E, coli and Salmonella spp. in soil and plants by application of composted and non-composted cow manures, This experiment was designed as a split plot with 3 replications where main plots were kind of vegetables namely asparagus, kale, coriander, stink weed, and peppermint, while the subplots were the kind of fertilizer (composted cow manure, non-composted cow manure and without manure).Research work was carried out at Mae Hai Agricultural Research Station and Training Centre, Chiang Mai University during January-April 2010. Soil from each treatment was periodically sampled at 7,21,35 and 49 days after planting, while sampling of vegetables was done once at 49 days for determination of E. coli and Salmonella spp. Application of composted cow manure did not show any contamination of E. coli in either soil or vegetable samples, except that of asparagus growing soil at 49 days. On the other hand, using of non-composted manure resulted in contamination of both E. coli in all soils (3.29-4.93 log MPN/g) and asparagus. Kale, coriander and stink weed at 2.78, 3.11, 4.38 and 2.78 log MPN/g, respectively with the exception of peppermint. Contamination of Salmonella spp. In soils of all treatments was fluctuated upon sampling period. However, most of vegetables fertilized by non-composted cow manure were contaminated with Salmonella, except peppermint, but the contamination was not found in those using of composted cow manure. This finding ensures that the application of composted cow manure could effectively decrease the possibility of contamination E. coli and Salmonella spp. In farmed vegetables. |
