In order to study the effect of farming systems on three Iranian garlic clones (Allium sativum L.), an experiment was conducted with split plot arrangements in 3 complete blockes in the growing seasons of the year of two successive years of 2004- 2005 at the experimental farm of the Environmental Science Research Institute of Shahid Beheshti University. Two factors were evaluated in the experiment: (a) farming systems in three levels (intensive, traditional and organic farming), as the main plots and, (b) garlic clones in three levels (Atoo, Hamedan and Virani clones), as the sub-plots.Results showed that the farming systems had significant effect (p¡Ü 0.01) on percentage of organic carbon, organic matter, total nitrogen, the availability of phusforus, potassium, EC and pH of soil. Amount of these parameters were increased in transition from intensive to organic system with the exception of pH. The highest value of this parameters were obtained in organic systems. Farming systems had significant effect (p¡Ü 0.05), on number of plant and bulb yields, too. The highest and the lowest bulb yields were obtained in intensive (9.5 ton/ ha) and organic(7.4 ton/ ha) systems, respectively. Though the yield was reduced as a result of organic farming, however, positive effect on soil structure, which consequents increase yield in long term can be expected.
