Abstract

Low solubility of phosphorus in the soils of Iran due to their alkalinity, and the reaction of phosphorus with Ca compounds are the most complicated problems in soil fertility in our country. Phosphate solubilizing microorganisms are among the most important bio-fertilizers that can help plant uptake of phosphorus. Bacillus and pseudomonas are the most genus of Phosphate Solubilizing Bacterias (PSBs). In contrast to chemical fertilizers, application of bio-fertilizers is difficult because their vitality is very sensitive and soil drought and solar radiation can effectively reduce the quality and quantity of the bacteria. Available phosphorus sources in soil could also affect the efficiency of PSBs. This experiment was conducted in order to evaluate the effect of water deficiency on two bacteria on the planting period of WHEAT in 2007-2008 in a greenhouse at Tarbiat Modares University (Iran) in a completely randomized design with two factors: bacteria genus with two levels: BACILLUS SUBTILIS and PSEUDOMONAS PUTIDA and drought stress on bacteria at 5 levels: application of bacteria one week before irrigation, application of bacteria two days before irrigation, application of bacteria one day before irrigation, application of bacteria just before irrigation, and application of bacteria in soil when the soil moisture content is at the field moisture capacity. Results of this experiment showed that plants with application of bacteria in the field moisture capacity produced the most grain yield, but there was no significant difference with the former treatment with application of bacteria one or two days before irrigation. Application of each of the bacteria one week before irrigation had no effect on plant grain yield. So it is recommended to farmers that they can use the pseudomonas and bacillus bacteria in soil at a maximum two days after irrigation. Total phosphorus uptake in WHEAT plants was high with application of bacteria at the field moisture capacity.
