Abstract:

This study was conducted as split plot factorial based on randomized complete block design in 3 replicates and 18 treatments were carried out during 2011-2012 at Agronomy and Plant Breeding Department, College of Agriculture and Natural Resources, Razi University, Kermanshah, Iran. In this experiment the main plots consisted of a factorial combination of manure (0, 10 and 20 tons.ha-1) and sulfur (0, 250 and 500 kg.ha-1) and subplots includes Thiobacillus bacteria (no use and use), respectively. The result of the experiment revealed that application of manure at various levels with recommended dose of Thiobacillus bacteria enhanced the growth and yield attributes in garlic over control. Analysis of soil nutrients using animal manure in organic carbon showed significant difference for traits including available nitrogen, phosphorus, potassium, manganese and zinc. In the all of parameters mentioned in 20 tons of manure treatment and treatments of sulfur, phosphorus, potassium, manganese, iron and zinc in soil pH caused significant difference that in all aforementioned traits other than manganese treatment 500 kg of sulfur has the amount of highest. However, we find out that the presence of Thiobacillusbacteria reduced soil pH and rate of iron absorbed is increased. The interaction between bacteria and sulfur, zinc and pH effects on the triple interaction was significant difference at the five percent level.
