الملخص

نفذت تجربة حقلية في محافظة طرطوس- منطقة الدريكيش خلال الموسم الزراعي 2024، وذلك لمقارنة تأثير الرش بحمض الجبرليك والتسميد بالنتروجين وتأثير تداخلهما في نمو وإنتاجية نبات الملوخية ، واستخدم من أجل ذلك الصنف البلدي من الملوخية. اتبع التصميم العشوائي الكامل ((CRD، شملت التجربة تسع معاملات وثلاثة مكررات: معاملة الشاهد (G₀N₀)، الرش الورقي بحمض الجبرليك (G₁N₀= 25 ppm, G₂N₀= 50 ppm)، والتسميد بالنتروجين(G₀N₁=15g/m² G₀N₂=25 g/m²,)، ومعاملات التداخل بينهما (G₂N₂ ,G₂N₁ ,G₁N₂ ,G₁N₁). أظهرت النتائج أن المعاملة بحمض الجبرليك تركيز50 ppm حققت تفوقاً معنوياً واضحاً على المعاملات الأخرى بعد 60يوماً من الزراعة، وأعطت أعلى القيم لمؤشرات النمو الخضري والإنتاجية المتمثلة في: ارتفاع النبات ( 107سم)، مساحة المسطح الورقي (977 سم²/نبات)، طول الفروع الجانبية (46.8 سم)، وزن النبات (41.6 غرام) وإنتاجية وحدة المساحة ( 2080غ/م²). ومن التداخل بين العاملين تبين أن الرش بكلا التركيزين 50 ,25 ppm من حمض الجبرليك والتسميد بأعلى معدل من النتروجين 25 غ /م² أدى إلى زيادة مؤشرات النمو الخضري معنوياً وزيادة وزن النبات والإنتاجية بالمقارنة مع بقية معاملات التداخل ومعاملة الشاهد.
