This study was conducted in the vegetable famiHort.

& land scape Dept., College of Agric.

And Forestry / Mosul Univ.

to study the effect of two levels of phosphate fertilization, zero.

40 kg P2O2 / Donum and spraying with three levels of seaweed extract, kelp 40.

Zero, 2,4 ml/1 in two pea cultivars namely: "Little Marvel and Fabreca".

Plants were sprayed twice, the first one at 3-5 true laf stage, whereas the second after 15 days from the first spraying.

Results indicated that phosphate fertilization & seaweed extract showed a clearly effects in TSS, protein percentage of seeds, nitrogen & phosphorus concentrations of leaves, in addition to number of root nodules plant.

Phosphate treatment gave the highest protein percentage (30.08%), while spraying with 4 ml/1 of seaweed extract resulted in the highest values of nitrogen, phosphorus concentrations in leaves, and the large number of root nodules/plant.

The results revealed also that cultivars varied between them in all parameters.
