Abstract
The study were conducted to investigate the influence of seaweed extract, chelated manganese, and two other chemical substances that are known as Agro promotor1(substance No.48) and Agro promotor2 (substance No.50) on the growth, yield, and quality of cauliflower. Results revealed that yield and its components increased with using each seaweed extract(3ml/l), chelated manganese (12%) at a concentration of 0.25g/l, and Agro promotor1 (substance No.48) at a concentration of 3 ml/l compared with control (untreated) treatment. Using bothseaweed and chelated manganese treatments exceeded other foliar spraying treatments and caused a significant increase in fresh weight of the whole plant, leaves fresh weight,leaves dry weight percent, yield, TSS and vitamin C. The increase in total yield ranged from 12.8-48.2% by using the previous treatments as compared with control. Also, foliar sprays of seaweed extracts led to the earliness in cauliflower production as compared with the control. This study recommends using seaweed extract at a concentration of 3ml/l or chelated manganese (12%) at a concentration of (0.25g/l) for cauliflower production. Agro promotor1 (substance No.48) at a concentration of 3 ml/l can be applied in case of unavailability of seaweed extract or chelated manganese (12%).

Abstract [العربیة]
اجريت هذة الدراسة بمزرعة الخضر البحثية – کلية الزراعة - جامعة اسيوط وذلک خلال الموسمين الزراعيين 2019-2020 ، 2020-2021 لدراسة تأثير رش مستخلص الطحالب البحرية، المنجنيز المخلبى وکذلک نوعين من المواد الکيميائية (مادة 48 ومادة 50) علي النمو والمحصول ومکوناتة فى صنف القنبيط الهجين سنوبول کراون. وکان الرش بمعدل 3 ملى/لتر من مستخلص الطحالب البحرية وبالمنجنيز المخلبى(12%) 0.25جرام/لتر وکذلک الرش بمادة 48، مادة 50 بترکيز 1.5 ملى/لتر، 3 ملى/لتر وتم الرش 3 مرات خلال موسم النمو. واوضحت النتائج الاتى: کان لکل من مستخلص الطحالب البحرية، المنجنيز المخلبى والمادة الکيميائية 48 بترکيز 3 ملى/ لتر تأثير واضح على صفات النمو والمحصول ومکوناته مقارنة بالکنترول. فکان لهما تأثير على طول النبات ووزنة، وعدد الاوراق، وقطر القرص. وايضا على وزن القرص الصالح للتسويق والمحصول الکلى وکذلک المواد الذائبة الکلية وحمض الاسکوربيک مقارنة بمعاملة الکنترول. ونستخلص من ذلک بأن استخدام کلا من مستخلص الطحالب البحرية، المنجنيز المخلبى والمادة 48 ادى الى تحسين النمو والمحصول والجودة فى القنبيط. فلقد زاد المحصول الکلى بمقدار12.8-48.2% عن معاملة الکنترول عند استخدام معاملات الرش المختلفة فتراوحت الزيادة فى المحصول الکلى ما بين 44.9 و51.5% عند استخدام مستخلص الطحالب البحرية، تراوحت ما بين 41.7-48.6% عند استخدام المنجنيز المخلبى. لذلک توصى الدراسة باستخدام مستخلص الطحالب البحرية والمنجنيز المخلبى للحصول على أعلى محصول صالح للتسويق، وفى حالة عدم توفرهذة المعاملة يمکن استخدام المادة الکيميائية 48 بترکيز 3 ملى/ لتر.
