The role of single inoculation and dubie and triple bacterial interaction Azospirullum brasilanse and VAM Glomuse Mossea and phosphate rock in availability NPK in the Rhizosphere Cucumber ( cucmuise stivease L. )‎

Abstract EN

Use biofirtilizer forming for quantity Bacterial Azospirullum braslieanse and VAM Glomus mossea and four levels of rock phosphate ( 0, 80, 140, 200 Kg.

ha -1) to study the single effect and double and triple interaction in the availability NPK In the Rhizosphere ( cucmuise stivease L.

).

Although the yield contains few nutrients but is considered one of the most important crops in Iraq ( 36).

It is fast growing and needs high fertilization of NPK ( 38).

It gave a solo biofertilizer bacterial and fungal and the level of rock phosphate 140 Kg ha -1 on characters NPK Measured in soil, achieving the highest significant increase in the values of treatments 50.43, 49.52, 50.70 mg N.

kg 1 and 16.02, 15.51, 16.26 mg P.

kg 1 and 191.54, 192.26, 192.32 mg K.

kg -1 On the sequence compared with Control.

The results of the double interaction in bacterial with fungal, bacterial interaction with phosphate rock, and fungi interaction with phosphate rock at 140 Kg -1.

ha Increase in characters NPK Measured in soil, , As it achieved the highest significant increase in treatments values 51.04, 52.5, 51.41 mg N.

kg - 1 16.28, 16.47, 16.81 mg P.

kg - 1 and 192.59, 192.24, 193.29 mg K.

kg -1 On the sequence in relation to its control.

The results of the triple interaction Bacterial, fungal, and phosphate rock was given at the level of phosphate rock 140 Kg.

Ha -1 increase in characters NPK Measured in soil, if triple interaction achieves the highest significant increase in the values of treatments 52.

84 mg N.

kg - 1 and 16.92 mg P.

kg m - 1 and 193.29 mg K.

kg m - 1 On the sequence in relation to its control.

The results showed that the triple interaction ( A.

braslieanse + Glomeas mossea + Phosphate rock ) at level 140 Kg.

Ha -1 Phosphate rock gave the highest significant increase in the values of nitrogen, phosphorus and potassium in the soil of the plastic house.

As the interaction between these microorganisms was positive and the impact of living one on the other was a catalyst in the increase of availability NPK.
