The seedlings were grown in a mixture of sandy soil and cow dung (3:1) and kept in polybags; EM was poured at different concentrations (0.1%, 0.5%, 1%, 2%, 5% and 10%). Seed germination rate and growth parameters of seedlings — shoot and root lengths, fresh and dry weights of shoots and roots, vigor, volume, and quality indices and sturdiness — were measured. The nodulation status influenced by EM was also observed, along with the measurement of pigment contents in leaves. The highest germination rate (72%) was observed in 2% EM solution while the lowest (55%) was found in control treatment. The highest shoot and root lengths (30.6 cm and 31.2 cm respectively) were recorded in 2% EM and were significantly (p

They are thought to be native to India from where they have been introduced in many different tropical and subtropical countries and are now growing throughout the world including Saudi Arabia (Moringa peregrina - a native species). Moringa tree is regarded as an excellent source of nutrition for human food and as treatment of many different ailments in the indigenous system of medicine for human diseases. Leaves, green pods, flowers and roasted seeds are used as vegetable; roots are used as spice; seeds are used for cooking and cosmetic oil. Plants contain important preventive and curative compounds, which are being used as antimicrobial agent. Moringa plants are also used for many other purposes like water purifier, green manure, mycotrophic plants, reforestation, alley crop, gum, ornamental, pest control, animal feed etc. Because of its numerous economic importances, easy prop...

Petunia hybrida is one of the most favorite ornamental plants growing all over the Riyadh city of Saudi Arabia. In the present study, we would like to highlight the Petunia as a mycotrophic plant for the management of mycorrhizal fungi under field conditions. Roots along with rhizosphere soils of P. hybrida were collected from various sites in Riyadh, Saudi Arabia to study AM colonization and biodiversity of AMF. The data obtained in this study indicated that P. hybrida is a very highly mycotrophic plants, and all the samples produced very high colonization with mycelium, vesicles, coiled hyphae and arbuscules. The significant variation was found with the occurrence of mycelium and vesicles among the locations but in case of arbuscules more or less same range of occurrence was found. Only different species of Glomus were observed in all the locations. Glo...

The productivity of these soils is thus limited. The mentioned soil constraints can conceivably be alleviated through the use of Bio-organic fertilizer. Bio-Organic fertilizer is composed of Organic matter and some beneficial soil microorganisms like Arbuscular mycorrhizal fungi, P-solubilizing microorganisms, Trichoderma, Rhizobium, Azotobacter, Azospirillum etc. Organic matter will improve the soil’s physical, chemical and biological properties and beneficial soil microorganisms can help increase plant growth by up-take of immobile nutrients, alleviate stresses like draught, salt, heavy metal, high temperatures etc.; establishment of transplanting seedlings, disease control, improve soil aggregates and control soil erosions etc. So Bio-organic fertilizer, an eco-friendly and cost effective technology, may be introduced immediately to increase quantitative and qualitative crop production in Arid Land Agriculture of Saudi Arabia. Particularly, in the Kingdom of Saudi Arabia (KSA), date palm cultivation is very important for the economy of the country. Usually the date palm plantations in KSA are grown with chemical fertilizers. As the date palm fruits are consumed directly so it is very important to grow fruits by using Bio-organic farming. To have safe fruits as food, Bio-organic farming may be introduced in the date palm plantations in KSA. This will not only to provide safe food but also improve the soil health (physical, chemical and biological conditions of the soil). Millions of people throughout the World are living in arid lands characterized as too dry for conventional rain fed agriculture. The dry land areas (40% of world land surface) are home to over 2 billion people, accounting for 35% of the world’s population. More than 90% of dry land inhabitants are in the developing world and 70% in rural areas. Approximately half of the poorest people in the world live in the dry areas. There is an urgent need to develop appropriate agriculture to feed theses millions of people. The Kingdom of Saudi Arabia, with a total

As the main pathogens, fungi can cause 70–80% of total plant diseases, leading to huge crop yield reduction and economic loss. For identification of fungal plant pathogens, mycologists and plant pathologists have mainly gone through two stages, viz. morphological observation and morphology/phylogeny, and the next era might be utilizing DNA barcodes as the tool for rapid identification. This chapter accounts i) the brief history of development for fungal identification tools and main concepts, ii) the importance and confusion of “One fungus, one name” for pathogen identification, iii) more or fewer species that we need in agricultural practice, and iv) the foreground of fungal plant pathogen identification. These will help to solve the practical problems of identification of fungal pathogens in agricultural production.

for application in the field and commercial production for business purpose

Highlight: Super Bio-organic fertilizer is composed of organic fertilizer (like compost from municipal organic waste and waste plant materials, cow dung and poultry manure, rice husk etc.); beneficial microbial inoculants (e.g. arbuscular mycorrhizal fungi and other beneficial soil fungi and bacteria including Rhizobium), green manure (from mycotrophic plants e.g. Sesbania, Cassia, Leucus etc ); natural fertilizers (rock phosphate , fish meal , bone meal etc); antimicrobial plants like Neem powder etc. So far not much work has been done throughout the world on the use of highly beneficial soil fungi, arbuscular mycorrhizal fungi (AMF), other beneficial soil fungi and bacteria, along with green manure plants and compost for growth improvement of crop plants in an integrated systems. Application of organic fertilizers improved structural stability and lower bulk density of the soil, improved moisture retention, water infiltration rate and hydraulic conductivity of the soil . Green manure will improve the soil's physical, chemical and biological properties. AMF and other beneficial microorganisms can help increase plant growth by up-take of immobile nutrients, alleviate stresses like draught, salt, heavy metal, high temperatures etc.; establish transplanting seedlings, disease control, improve soil aggregates and control soil erosions etc. The green cultivation technologies are an innovative technology and it will be helpful to the growers for organically produced safe plant products of crop plants for human consumption and medicinal purposes, Neem leaf powder will be protecting the crop from insect pest and soil borne pathogenic organisms. Natural fertilizers will be helpful for proper growth of the plants. In conclusion, the Super Bio-organic is an ideal fertilizers for the production of safe food and medicinal plants for human consumption. The technology will be highly useful right now in Date Palm, Olive, vegetable crops and other food crops in your country. Additional advantage of using organic wastes of different sources for the preparation of basic organic materials or preparation of Bio-organic fertilizer and no use of chemical fertilizers and pesticides will directly or indirectly reduce the environmental pollution.

Requirements :
Compost / manures as base material for Super Bio-organic may be prepared from Municipal organic wastes or plant material of different types. For our own products we need several industrial establishments in various suitable locations where raw material may be readily available. One cycle of preparation of mature/ composts will need about 45-60 days. The establishment will be raised in several cities where land and supply of raw materials will be available according to the requirement. Some of the microbial inoculants (MI) may be added during the preparation of raw materials to facilitate rapid decomposition and also to transfer the inoculants to the field or plantings sites through Super Bio organic fertilizers. Rest of the MI may be incorporated before packing. Most of the MI may be prepared under laboratory conditions except Arbuscular Mycorrhizal Fungi (AMF) which may be developed under field conditions with suitable mycotrophic plants (like Sesbania, Cassia, Leucus etc for inoculum production as well as for green manure) as because MI are obligate symbionts. The measured amount of MI, natural fertilizers, neem powder etc may also be added during packing. We need a research laboratory and green house space with sufficient manpower for continuous improvement of our products through practical research with candidates crops by measuring the physical and chemical parameters of plants and soil physical and chemical parameters may also be estimated to determine the residual value.

The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier is one of the most severe and deadly pests of date palms Phoenix dactylifera L. The Integrated Pest Management (IPM) strategies in controlling the infestation of RPW in date palm throughout the world involves surveillance, cultural control, chemical control, mass pheromone trapping, biological control, mechanical control, quarantine control etc. with limited success. To handle this gigantic problem of management of RPW in date palm, it is urgently in need of new initiatives to find out appropriate methods for control of RPW integrating IPM strategies, especially the adverse effects of pesticides and low efficacy of other methods followed for IPM. First innovative ideas may be integrated with existing IPM by covering the base of the stems with insect proof net to avoid the insects. In next innovative approach, pests and disease resistance stock and /or tissue cultures plantlets may be selected for raising new plantation to avoid infestation of RPW through good stocks. In a third approach, green cultivation techniques with bio-organic (composed of organic matters, beneficial soils microorganism and green manure crops etc) may be introduced to provide balanced nutrients, improve water relations, avoid soil borne pathogenic fungi, provide mulches, inoculum for next year crops etc. This integration with IPM will help in growth of healthy plants that will directly or indirectly help the plants to avoid infestation of RPW. Another added method is to incorporate the entomopathogenic fungi and nematodes with the bio-organic which will kill the insects in the soils and the airborne inoculum of fungi will serve as infective propagules for infestation of the insects. In another very effective approach, instead of using pesticides, eco-friendly and costs effective silver Nano particles (available in our laboratory) may be integrated by spraying all plants and in addition injecting the infested plants. This can also be used as dressing to clean areas of infested parts (tissues) as preventive and curative measures in controlling the RPW. Again in another new integrated approach, along with the conventional bio pesticides products, the insect repellent trees, herbs and shrubs like Neem (Azadirachta indica), Mint (Mentha), Lemon Grass (Cymbopogon citratus), Lavender, Petunias, Chrysanthemums, Marigolds etc. may be planted in between the rows and the plants to avoid contact of the date palm plants with RPW insects. This also provides leaf biomass through shredded leaves in the soils as well as to killing harmful insects and pathogens by their insecticidal and antimicrobial activities. They also act as mulches crops and weed suppressive plants. In final integrated approach, modified trap with light and fan (developed in our laboratory) may be introduced. We hope and believe that our proposed new approaches will provide useful ideas in controlling the RPW, a deadly pest in date palm.

سوسة النخيل الحمراء (RPW) Rhynchophorus ferrugineus Olivier هي واحدة من الآفات الفتاكة والقاتلة لنخيل التمر Phoenix dactylifera L ، واستراتيجيات إدارة الآفات المتكاملة (IPM) في السيطرة على الإصابة من سوسة النخيل الحمراء RPW في جميع أنحاء العالم ينطوي على المراقبة و محاولة السيطرة على هذه الأفة عن طريق المكافحة الكيماوية، وأستخدام مصائد الفرمون ، والمكافحة البيولوجية، والمكافحة الميكانيكية، والحجر الزراعي وما إلى ذلك من وسائل ثبت أن نجاحها محدود.
للتعامل مع هذه المشكلة و لإدارة سوسة النخيل الحمراء RPW في النخيل، فإننا بحاجة ماسة إلى مبادرات جديدة للتعرف على الطرق المناسبة للسيطرة على سوسة النخيل الحمراء وربما دمج بعض استراتيجيات الإدارة المتكاملة للآفات، خاصة في ضل الآثار الضارة للمبيدات والفعالية المنخفضة للأساليب الأخرى. الأفكار المبتكرة الأولى قد يكون دمج IPM مع الإدارة المتكاملة للآفات القائمة من خلال تغطية القاعدة و انسجة ساق النخلة بشبكة واقية لمنع الاصابة بالحشرات.
وفي نهج مبتكر اتخر، يمكن اختيار الاصناف و/ أو الشتلات المقاومة للأمراض, او عن طريق زراعة الأنسجة حيث يمكن تطوير اصناف مقاومة لهذه الافغه لتجنب الإصابة من سوسة النخيل الحمراء RPW من خلال جذع الشجرة الجيد. وفي نهج ثالث، يمكن استخدام اسلليب الزراعة العضوية و المكون العضوي (يتألف من المواد العضوية، والكائنات المجهزة المفيدة في التربة، ومحاصيل السماد الأخضر) مما قد يوفير المواد الغذائية المتوازنة، وتحسين العلاقات المائيه وتجنب الفطريات المسببة للأمراض في التربة، وبالتالي هذا التكامل مع الإدارة المتكاملة للآفات يساعد في نمو النباتات الصحية حيث تساعد IPM بشكل مباشر أو غير مباشر في تحسين قدرة النباتات لتجنب الإصابة من سوسة النخيل الحمراء RPW .
وطريقة أخرى مضافة هو دمج الفطريات الممرضة للحشرات والديدان الخيطية(تانيماتودا) مع المكون العضوي مما سيقتل الحشرات في التربة ويقلل من احتمالية الاصابة و غزو الحشرات. في منهجيه أخرى فعاله جدا وصديقة للبيئة (متوفرة في مختبرنا) ، قبدلا من استخدام المبيدات، قد يكون استخدام جزئيات النانو الفضية ورش جميع النباتات بالإضافة الى حقن النباتات المصابة، و يستخدم أيضا مع كشط وتنظيف المناطق المصابة (الأنسجة)، كتدابير وقائية وعلاجية في السيطرة على سوسة النخيل الحمراء RPW .
مرة أخرى في نهج متكامل جديد آخر، تستخدم المنتجات او المبيدات الحيوية التقليدية، حيث تزرع الأشجار والأعشاب والشجيرات الطارده للحشرات مثل شجرة النيم (Azadirachta indica) ، والنعناع (Mentha) وعشب الليمون (Cymbopogon citratus) ، ولافندر، وزهور البتونيا، والأقحوان، والقطيفة وما إلى ذلك بين الصفوف لتجنب الاتصال بين اشجار النخيل و وسهولة انتقال سوسة النخيل الحمراء بينها. وهذا يوفر أيضا كثافة في الأوراق المتساقطة على سطح التربة، مما يساعد في قتل الحشرات الضارة، ومسببات الأمراض عن طريق مكوناتها ونشاط الميكروبات التحليلي لهذه المواد ، وهذا أيضا يعمل بمثابة تغطية لسطح التربة وتقليل من نمو الاعشاب الضارة.
وفي نهج متكامل نهائي، قد تكون إدخال فخ معدل. نأمل ونعتقد أن نهجنا الجديد المقترح سيوفر أفكارا مفيده في المراقبة على سوسة النخيل الحمراء RPW ، الآفة القاتلة في النخيل.
