Abstract EN

This study was conducted in vegetable farm/ Hort.

& Landscape Dept./ College of Agric.

& Forestry/ Mosul Univ.

during the growing season 2011/2012, to study the effect of two levels of phosphate fertilizer, zero, 40 kg P2O5/Donum, and spraying with different levels of seaweed extract, "Kelp 40", zero, 2, 4, ml/l in two pea cv.

namely: "Little Marvel, Kanadia".

Plant sprayed twice, the first at 3-5 true leaf stage, the second after 15 days from the first spraying.

Results showed that phosphate fertilizer and spraying with seaweed affected on the stem length, chlorophyll (%), maturity, number of pods/plant, No.

seeds/pod, and total dry seeds yield in the two cultivars.

Results indicated that twice spraying with "Kelp 40" at 4 ml/l gave greater increase in the percentage of dry seeds yield 23.45%, and showed that cultivars differ in all the studied parameters.
