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 .

The current experiment has been conducted to study the effect of foliar application of seaweed extract (AIGA CIFO 3000) at three concentrations; 0, 1.5 or 6mg. L-1 and NPK fertilizer at three concentrations also; 0, 1.5 or 3 g. L-1 and their combination on some growth parameters and yield of cucumber Cucumis sativus L. cv. Selion. The experiment was carried out in a plastic house at the College of Agriculture University of Al-Qadisiya during the period from 28-12-2013 to 22-4-2014. Radomized complete block design has been used with three replications. The spray with seaweed and NPK fertilizer is done twice; the first one is after one month of planting in the permanent place, and the second one is after two weeks from the first spray. Plant height, number of branches, leaf chlorophyll content are have been measured. Also, early and total yield and fruit characters such as length, weight, and fruit diameter, total soluble solids and vitamin C are calculated. The results show that plant height and number of branches are increased significantly with seaweed and NPK treatments, especially at the higher concentrations. Also, chlorophyll content in leaves is also increased significantly at the higher concentration of the seaweed. The early yield is increased at both concentrations of both factors used, while there is a significant increase in total yield at the higher concentration of both factors in compare to control. The two concentrations of seaweed extract cause significant increase in fruit weight, while the treatments have variable effects with regard to fruit length and diameter. There was a gradual increase in TSS and vitamin C with the increase of the concentrations of both seaweed extract and NPK fertilizer.
