Abstract
A field experiment was carried out during agricultural season 2011/2012 to study the effect of sulfur addition with some organic fertilizers on plant growth and the yield of garlic Allium sativum L. which has been got as cloves from local markets. Experiment was conducted according to the randomized complete block designe withing factorial experiments by three replicates. Using Duncan test polynomial on possibility of 5% to compare averages of treatments, Eighteent sulfur addition was applied levels of zero and 1000 kg.ha-1 and poultry manures of 10 and 20 tons.ha-1. Some fertilizers and organic extracts such as Italpollin in levels 1 and 2 tons.ha-1. Afoiler organic extracts were applied on levels 2.5 and 5 ml.liter-1. The results showed that sulfur addition at a rate of 1000 kg.ha-1 caused a significant increase on chlorophyll leaves content and plants harvested, cloves number, mean clove weight, total heads yield and biological yield, poultry manure application at the level of 20 tons.ha-1 appeared also a significant increase as above, also intraction between sulfur and levels of added organic fertilizers increased the above studied properties, 1000 kg.ha-1 of sulfur with (20 tons.ha-1) of organic fertilized had a significant increase on studied properties accept mean weight of clove and
