AbstractUse 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 .
