تأثير التسميد الفوسفاتي و الرش بالمستخلص البحري Kelp 40 في نمو و إنتاجية صنفين من البزاليا Pisum sativum L.

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.
