Garlic (Allium sativum L.) is an important medicinal herb that is readily available everywhere. It contains a substance called Allicin, which has anti-bacterial properties that are equivalent to weak penicillin. In order to investigate the effects of various planting beds on yield and yield components of garlic, a field experiment was conducted based on randomized complete block design with four replications at the Agricultural Research Station, Azad University of Torbat Jam, during growing season of 2009-2010. Treatments including 20 and 40 t.ha-1 manure, 20 and 30 t.ha-1 sand and 5 and 10 t.ha-1 wheat straw and control. The results indicated that the planting bed had significant effects (p≤0.05) on the leaf dry weight, bulb number, biological yield and economical yield of garlic. The highest biological and economical yield of garlic were observed in 40 kg manure with 1085.4 and 723.5 g.m-2, respectively. There was a positive correlation between leaf weight and bulb number with economical yield of garlic. So, it concluded that the agronomic operations enhanced growth characteristics and bulb number of garlic.
