The experiment was conducted in an agricultural land belonging to Al-Fayhaa Company for Poultry Egg Production, located in village of Sinjar, Babylon province , for the year 2021, to study the effectiveness of the interaction between calcium silicate and Pseudomonas fluorescens bacteria in relieving water stress of wheat and its impact on the effectiveness of biomass in the soil and availability of some elements for the plant. The experiment included two factors, the first is the addition of calcium silicate and Pseudomonas bacteria and their interactions at four levels (without addition, Pseudomonas bacteria 10 ml, calcium silicate at an average, Pseudomonas bacteria + calcium silicate) and symbolized by the symbol (b3, b2, b1, b0), and the second factor is irrigation periods Which included three irrigation periods (7, 14, 21) days and symbolized by (C2, C1, C0).The results showed that the interaction of Pseudomonas bacteria + calcium silicate (b3) was significantly excelled on the rest of the other treatments and gave the highest average of biological activity 24.83 mg/g, the highest average of biomass carbon MBC 701.33 (mg.g-1 ). The phosphorous content of the leaves is 16.46 mg/gm and the potassium content in the leaves is 35.35 mg/gm. Also, the treatment of calcium silicate (b2) excelled the nitrogen content in the plant 25.66 mg / g, grain yield 4.16 tons / ha, The results also showed that the treatment of irrigation periods every 21 days (C2) was significantly excelled on the rest of the other treatments and gave the highest average of biomass carbon 1040.12 mg / g, nitrogen content in the plant 29.23 mg / g, phosphorous content in the plant 20.66 mg / g, potassium content In the plant 36.54 mg/gm, while the treatment of irrigation periods every 14 days (C1) gave the highest rates of the biological activity traits for releasing CO224.75 mg/gm, and the highest bacterial density 25×107.While the results of the interaction between bio fertilization and irrigation periods showed a significant effect on the studied traits, the (b1C2) treatment significantly excelled on the rest of the other treatments and gave the highest rate of biomass carbon 1350.50 mg/g, phosphorous content in the plant 25.5 mg/gm, nitrogen content In the plant 37.05 mg / g, The potassium content in the plant is 39.01 mg/g, and (b2C0) treatment was significantly excelled , and the highest values for grain yield were 4.26 tons/ha. We conclude from this study that the bacterial silicon interaction improved the biological activity, biomass and elemental content in the leaves and reduced the water stress on the wheat crop.
