• Agricultural field trial or on-farm trial, for the purpose of Maintaing a higher yield of the local varieties such as: “Eiwess, Hendi & zebdeya, fonse, balady “
• Current experiment was carried out on local Egyptian traditional mango varieties to investigate the effect of the current protocol used when applied to old mango trees (30 years old) in the preharvest period. The above-cited protocol combinations with the mentioned dosage & concentrations, were sprayed 5 times on healthy mango trees in an orchard adopting recommended agricultural practices.

Protocol steps:

1st spray (Fungicidal application: Micronized Soreil KZ - Dose 1500 gm, conc. 70% - Feb 2025, Fruit set stage

2nd Spray: (Fungicidal application: TOPSIN 70%WP, Dose: 400gm – March 2025

3rd spray: (Fungicial application: SUMAGHT Powder – Dose: 500Gm – April 2025

4th spray: (Insecticide application: LAMBADCYHALOTHRIN 10% EC), dose: 2 Liters – May 2025

5th spray: (Insecticide application: TRIPLE PYROTHIDE comb.Dose: 2 Litres) – June 2025

The above protocol also included the use of Fertilizers (3cycles) in parallel as below:

1st cycle: date Feb 2025, Magnesium sulphate Dosage: 25Kgm + Ammonium Nitrates 50 Kgm

2nd cycle: date: EARLY June 2025, Ammonium Nitrates 50 Kgm + MgSO4 25Kgm + Kso4 Potassium Sulphate 25Kgm

3rd cycle: Early July 2025, Ammonium Nitrates 50 Kgm

The mango farm is situated in El Obour Orabi farms, kalioubiya. Immediately after harvest, a sample of 100 mature intact fruits was taken from each treatment and control. Fruits were transported to fruit handling research laboratory for cold storing (13 ± 1°C and RH 85-90%) and estimating fruit quality & yield was weighed each month.

Key findings:

• The results indicated that treatments caused a pronounced beneficial effect in lowering fruit drop, counted after 2 months of fruit setting, compared to control trees which recorded a percentage of drop between 80% and 94%, in both seasons

• The production yield in summer 2025 weighed a total of: 5 Tons for the cultivated area of 4.5 Feddans
• Proactively combating climate-induced heat stress and fluctuating temperatures by shifting to heat-resistant foreign varieties: Naomi, Keitt, Kent, Crimson, and Yasmina are highly advised by the Author in-line with the recommendations of the Egyptian Ministry of Agriculture.
• Greenhouse Protection & Canopy Management, as well as Advanced Pest Surveillance & Technology as digital documentation, remote sensing, and expanded trap monitoring to ensure early detection of fruit flies and other pests, all are highly advisable by the Author for better future results, in-line with the recommendations of the Egyptian Ministry of Agriculture & Land reclamation.

Global agriculture is moving at an accelerating pace toward adopting zero-emission and eco-friendly solutions, in line with sustainable development requirements. In this context, natural plant extracts are no longer merely an alternative to chemical pesticides; rather, they have become a fundamental pillar of modern biological control systems. This lecture highlights the journey of these promising compounds, starting from their innovation and development in "green laboratories" based on clean chemistry principles, leading to the challenges and opportunities of their actual application on a large field scale. The lecture will focus on reviewing the roadmap for biotechnology transfer through three main axes: Innovation in the Green Lab: Reviewing eco-friendly extraction methods (such as the use of natural deep eutectic solvents and ultrasound applications) that ensure obtaining the highest concentration of bioactive compounds (such as phenols and terpenes) without causing environmental pollution. Dual Inhibition Mechanisms: Explaining how these green extracts function through multi-target mechanisms, which minimizes the chances of pests and pathogens developing biological resistance, alongside their role as indirect stimulants of the plant's systemic acquired immunity. Field Application and Simulation: Discussing the traditional gap between the controlled laboratory environment and open field conditions (the impact of UV radiation, temperature, and humidity), while presenting innovative solutions to enhance the stability of extracts in the field. Finally, it is crucial to recognize that investing in "green biocontrol" is not just an environmental choice, but an economic necessity that ensures the production of safe, residue-free crops. These extracts must transition from laboratory shelves into the hands of farmers as effective and sustainable commercial products.

استخدام الأحماض الهيومية (الدبالية) كمنشط ومحفز نمو على أشجار النخيل

أبحاث حول استخدام الاحماض الهيومية كمنشط حيوي فعال على شجرة النخيل

- فهم طريقة وكيفية تأثير الاحماض الهيومية

فوائد استخدام الاحماض الهيومية كمنشطات حيوية على شجرة النخيل

أظهرت نتائج التجارب الميدانية التأثير الإيجابي للأحماض الهيومية على اشجار النخيل

الفوائد التجارية للمزارعين من خلال زيادة كمية ونوعية الانتاج

الملخص:

تعاني زراعة أشجار النخيل في شمال افريقيا ودول الخليج من مشاكل ارتفاع ملوحة التربة وانخفاض خصوبتها والاجهاد الحراري العالي ونقص الماء.

يمكن للأحماض الهيومية (الدبالية ) المستخلصة من مادة الليونارديت أن تقلل من هذه الاثار السلبية على أشجار النخيل حيث انها تعمل كمحفزات ومنشطات نمو حيوية للنبات ومحسنة لخواص التربة.

تعمل الاحماض الهيومية على تحسين بنية وقوام التربة وتزيد من خصوبتها وترفع سعتها الحقلية واحتفاظها بالماء . كما تقلل الاحماض الهيويمة من اثر الملوحة العالي في التربة من خلال رفع سعة التبادل الكاتيوني للتربة. تحفز الاحماض الهيومية على زيادة نمو الجذور وترفع من قابليتها على امتصاص العناصر الغذائية من التربة. أظهرت نتائج استخدام الاحماض الهيومية المحببة
( البرل هومس) على أشجار النخيل في الإمارات والسعودية من انخفاض تأثير ملوحة التربة وزيادة قابلية امتصاص الاسمدة المضافة للتربة مقارنة بأشجار النخيل التي لم تعامل بالأحماض الهيومية. كما أدى استخدام الاحماض الهيومية المحببة على زيادة إنتاج أشجار النخيل بحوالي 17٪ مقارنة بأشجار النخيل غير المعاملة وأدت أيضا في نفس الوقت الى ارتفاع جودة ثمار التمر .

Water scarcity, high temperature, and salt accumulation on lands are serious problems causing significant losses to crop yield. Developing environmentally friendly strategies to mitigate these agricultural problems could boost agricultural production in unfavorable conditions and/or uncultivated lands. We discovered that pretreatment with ethanol, a cheap and environmentally friendly chemical, enhances drought, heat, and high-salinity tolerance in various plants, such as Arabidopsis, rice, wheat, maize, lettuce, tomato and cassava, and named the technology as EGAO (Ethanol-based Global Agricultural Optimization; http://pgn.riken.jp/egao/index_en.html). Ethanol pretreatment enhances high-salinity tolerance by detoxifying ROS, and induces heat tolerance through stimulation of the endoplasmic reticulum stress response, increased expression of stress resilience-related genes encoding LEA proteins, ROS detoxification enzymes, and activated gluconeogenesis. Furthermore, ethanol pretreatment induces stomatal closure and increases sugar accumulation, resulting in enhanced drought tolerance.
