- Harnessing innovative technologies in Water and land for Sustainable Agriculture and Food Security improvement in Africa
Food insecurity is a major challenge to Africa region. African region is endowed with vast resources (land, water and human resources) suitable for agriculture, livestock production, and forestry and fisheries development, among others. However, agriculture is characterized by relatively low productivity. FAO 2015 estimated that there were some 680 million hungry people in the world, more than 250 million of whom in sub-Saharan Africa. Currently there is real famine in some African countries because of less food production. Food imports is increasing, while agricultural productivity is stable and or decreasing despite huge potential. There is potentiality-given the huge amount of resources-for the region to feed its population and the world. The main problems of food insecurity in the region are poor utilization and mismanagement of resources which associated with traditional practices in agricultural sector and in food production system.

- أوامر الأداء في الأحكام المدنية "دراسة مقارنة"
يسعى الباحث من خلال هذا البحث لبيان أومر الأداء، طبيعتها وشروط وإجراءات إستصدارها، وذلك من خلال القانون الوضعى ، حيث درس الباحث بالتحليل تعريف أوامر الأداء وطبيعتها، فأمر الأداء حكم يصدر من القاضى فى موضوع دعوى رفعت بإلإجراءات التى حدّدها القانون لهذه الدعوى، فهو حكم قطعى ولا يغيّر من هذا الوصف، إنّ الإجراءات التى تسبق صدور الأمر والتى يبنى عليها، ليست الإجراءات التى نصّ عليها القانون لرفع سائر الدعاوى. كما تناول الباحث الشروط التى يجب توافرها لإستصدار أمر بالأداء وكيفية إستصداراه . كما بينّ الباحث إجراءات التظلم فى أمر الأداء، وإستئنافه، وتنفيذه. وسلك الباحث المنهج الإستقرائى التحليلى حيث توصل الباحث الى جملة من النتائج أهمها الخروج بتعريف شامل لأوامر الأداء، يستوعب جميع العناصر والصور الرئيسية لمصطلح أمر الأداء وهو حكم يصدر من القاضى فى موضوع دعوى رفعت بإلإجراءات التى حدّدها القانون لهذه الدعوى، فهو جكم قطعى ولايغيّر من هذا الوصف إنّ الإجراءات الت ىتسبق صدور الأمر والتى يبنى عليها، ليست الإجراءات التى نصّ عليها القانون لرفع سائر الدعاوى. كما توصل الباحث إلى عدة توصيات أهمها التوصية للمشرّع السودانى بالاهتمام بأوامر الأداء والتوسّع فيها، لتشمل بجانب ديون النقود الثابته بالكتابة، المنقولات المعيّنة بنوعها ومقدارها، وكذلك الديون الثابته بورقة تجارية كالكمبيالة والسند الأذنى والسند لأمر والسند لحامله والشيك.
The researcher endeavor through this research to clarify the orders of performance, its nature ,the conditions and issuance procedures, through the positive law. Where the researcher analytically, examined the definition and nature of performance orders. The performance order is a sentence issued by the judge on the subject of a lawsuit brought up by the procedures specified by the law for this case. And does not change this description, the actions that precede the issuance of the order on which it is based, not the procedures stipulated by the law to raise all other cases. The researcher also tackled the conditions that must be fulfilled for the issuance of the performance order and how it can be issued. The researcher also identified grievance procedures in the performance order, its appeal and its execution. The researcher followed the descriptive analytical method. The study obtained many results, the most important of which is the introduction of a comprehensive definition of performance orders, which includes all the main elements and images of the term performance order, which is issued by the judge on the subject of a lawsuit filed by the procedures specified by the law for this case. The actions that precede the issuance of the order on which they are based are not the procedures provided for by law to raise all other cases. The researcher recommended the followings, attention should be paid to the orders of performance and expansion in addition to the fixed money debt in writing, the specific movables of their type and amount, as well as the fixed debt with a commercial paper such as cash,

- Allelopathic effects of Jimsonweed (Datua stramonium L.) seed on seed germination and seedling growth of some poaceous crops
Laboratory and greenhouse experiments were carried out at the Faculty of Agricultural Sciences, University of Gezira, Sudan in season 2014/15 to study the allelopathic effects of Jimsonweed (Datua stramonium L.) seed on seed germination and seedling growth of some poaceous crops. Laboratory experiments were conducted to study the allelopathic effects of aqueous extract of Jimsonweed (Datua stramonium L.) seed on seed germination of sorghum (Sorghum bicolor [L.] Moench), millet (Pennisetum glaucum [L.] R. Br.), maize (Zea mays L.) and wheat (Triticum vulgare L.). Six concentrations (0, 20, 40, 60, 80 and 100%) of the aqueous extract of Jimsonweed seed were prepared from the stock solution (50 g / l). Treatments, for each crop, were arranged in completely randomized design with four replicates. The seeds were examined for germination at three days after initial germination. Greenhouse experiments were conducted to study the allelopathic effects of Jimsonweed seed powder on seedling growth of the same poaceous crops. The seed powder was incorporated into the soil at rate of 0, 1, 2, 3, 4 and 5% on w/w bases in pots. Treatments, for each crop, were arranged in completely randomized design with four replicates. The experiments were terminated at 30 days after sowing and the plant height, number of leaves and root length of crop seedlings were measured as well as plant fresh and dry weight. Data were subjected to analysis of variance procedure. Means were separated for significance using Duncan`s Multiple Range Test at p £ 0.5. The results showed that the aqueous extract significantly reduced seed germination of the tested poaceous crops and there was direct negative relationship between concentration seed germination. Also, the results showed that incorporating seed powder into the soil significantly decreased plant height, number of leaves and root length of crop seedlings as well as seedling fresh and dry weight. In addition, the reduction in seedling growth was increased as seed powder increased in the soil. It concludes that Jimsonweed has allelopathic effects on seed germination and seedling growth of the poaceous crops.
