Title: Evaluation of Rock and Super Phosphates Effects on Yield and Yield Components of Rice (Oriza sativa L.) With and Without Phosphate Solubilizing Bacteria
Abstract: Impact of phosphorus application which is one of the major nutrient elements that could limit agricultural production was studied in form of phosphorus solubilizing bacteria (PSB), Bacillus coagulans, with and without various amounts of phosphorous fertilizer on rice under both pot and field experiments. The filed experiment was conducted in spring season of 2005 at the Rice Research Institute located in Tonekabon- Iran at 50.53, N and 36.49, E. A RCBD design with three replications was used. Fertilizer treatments included of granule bio-phosphate (100 kg ha ), phosphate solubilizing bacteria (Bacillus coagulans), rock phosphate (A 1 rock phosphate + phosphate solubilizing bacteria. Some of studied experimental variables were comprised grain yield, full filled grain, effective tiller (fertile tiller), 1000-grain weight and length of panicle. The results of this study indicated that, there were no significant differences in fertile tillers and length of grain in both pot and field conditions. But significant differences in 1000-grain weight and number of filled grain were observed in both pot and field experiments. The results also showed that grain yield was increased by combined treatments PSB inoculation with rock phosphate or TSP. In the meantime the most grain yield per panicle was observed in the PSB and the least in the control treatments. The lowest and the highest dry weights were obtained in plants treated with A+PSB and TSP, respectively at the anthesis.
