The study contains 10 treatments with 5 replicates for each treatment. Data was calculated using Simple Random Design. Foliar application with Potassium humate at 6 ml\/l resulted in highest plant height (80.85 cm). Moreover, foliar application of seaweed extract at 200 g\/l resulted in the highest values (5.20,\u00a0 48.30 cm2, 19.18, 6.33, 10.56 cm, 145.89 kg\/donum\u00a0 for number of brunches\/ plant, leaf area, number of pods\/ plant, number of seeds\/ pod, pod length, and productivity respectively) were observed when sea weed extract was foliar sprayed at 200 g\/l. The lowest values for the morphological and productivity parameters were recorded in control plant.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Keywords:<\/strong> Pea, Potassium humate, amino acid, seaweed extract, growth, productivity.<\/span><\/p>\n<p><strong><span style=\"font-family: 'times new roman', times, serif;\">\u00a0Full paper in English: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v13n4p31.pdf\">PDF<\/a><\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Roula Bayerli1 and Nour AL Qabbani2* 1 Department of Horticultural Science, Faculty of Agricultural Engineering, Damascus University, Syria.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 (*Corresponding author: Nour Al Qabbani, Email: nqabbani84@Gmail.com, 0947729325) Received: 25\/11 \/2025\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0Accepted:4 \/03 \/ 2026 Abstract:\u00a0 The present study was carried out &hellip; <a href=\"https:\/\/agri-research-journal.net\/SjarEn\/?p=11587\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-11587","post","type-post","status-publish","format-standard","hentry","category-sjar"],"_links":{"self":[{"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=\/wp\/v2\/posts\/11587","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=11587"}],"version-history":[{"count":4,"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=\/wp\/v2\/posts\/11587\/revisions"}],"predecessor-version":[{"id":11604,"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=\/wp\/v2\/posts\/11587\/revisions\/11604"}],"wp:attachment":[{"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=11587"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=11587"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/agri-research-journal.net\/SjarEn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=11587"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
