This research was conducted during 2006-2007 growing season on an experimantal area

devoted to organic agriculture at the Research Farm of Faculty of Agriculture, University of Mustafa Kemal. The onion cultivar Banko was used in the study. The effects of conventional and six different organic production sytems (1-Conventional, 2-Farmyard manure,3- Commercial organic fertilizer, 4- Zero input, 5- Green manure, 6- Green manure + commercial organic fertilizer, 7- Green manure + farmyard manure) on growth, yield and yield component of onion were evaluated. Common vetch (Vicia sativa) was sown and incorporated with soil at flowering stage as green manure. Composted cattle manure was applied at dose of 3 t/da to the plots before sowing as farmyard manure. As commercial organic fertilizer, the Efficient Microorganism Complex (EM™) was applied. Plant height (cm), stem diameter, bulb diameter (mm), bulb lenght (cm), number of foliage leaf, protein content (%), bulb dry matter (%) and bulb yield (kg/da) were determined. The highest bulb yield (2886.4 kg da-1) was obtained from the green manure + farmyard manure production system and followed by the conventional production system (2399.3 kg/da).
