  • رؤية قرآنية حول مفهوم الإصلاح

يهدف البحث إلى إيجاد تعريف لمفهوم الإصلاح من خلال دلالات نصوص الوحي قرآناً وسنة، ومن خلال معاجم اللغة، وعند أهل الصناعات والحرف المختلفة، واستطاع الباحث من خلال دعوات الأنبياء أن يثبت أن مفهوم الإصلاح يشمل كافة جوانب الحياة؛ الفكرية والثقافية والروحية والاقتصادية والسياسية والاجتماعية، وإزالة كافة مظاهر الفساد، واستخدم الباحث المنهج الوصفي التحليلي، وتوصل للعديد من النتائج من أهمها: أن الإصلاح يتم بالتدرج الهادي المستمر وتشكيل القناعات، لا بالثورات وإراقة الدماء، وأن الإصلاح المعرفي هو الموقف النقدي التقويمي الذي يتجاوز كل من موقفي الرفض والقبول المطلق، إلى موقف قائم عللى قبول وأخذ ماهو صواب، ورد ورفض ماهو خطأ.

  • RESISTANCE FOR POWDERY MILDEW (SPHAEROTHECA FULIGENIA) IN SUDANESE OKRA (ABELMOSCHUS SPP) GERMPLASM

Powdery mildew (PM) is the most important disease affecting okra production in winter and autumn seasons in Sudan. Sphaerotheca fuliginea, Erysiphe cichoracerum and leveillula taurica are the causal agents of the disease. One hundred forty three accessions of okra germplasm were screened for resistance in 1999. Thirteen accessions were selected and screened in seasons 2000 and 2001. The results of first season showed that HSD 0874 plants were resistant while, HSD 0039, HSD 0061 and HSD 0089 were slightly infected. The results of 2000 and 2001 seasons showed that only HSD 0874 was resistant to the disease without any single infected plant. In 2007 and 2008 only HSD 0874 was compared with 4 check varieties. HSD0874 continue to be completely resistant. Screening for PM was done under natural infection conditions and infected leaf samples were periodically collected and investigated in the laboratory for identification of the causal agent(s). The results showed that Sphaerotheca fuligenia is the associated causal agent for PM on okra. HSD 0874 was selected as a source of resistance for PM caused by Sphaerotheca fuliginea.

  • إشكاليات المنهج المؤصل في الجامعات السودانية والحلول المقترحة(جامعة القرآن الكريم وتأصيل العلوم نموذجاً).

يحاول هذا البحث من الناحية العملية النظر في مشكلة المناهج المؤصلة بصفة عامة، ومسألة تاصيل المناهج في الجامعات السودانية من حيث الرؤى الكلية التي يمكن أن تنطلق منها، والإشكالات التي تواجهها، والتحديات والصعوبات التي تعترض محاولات إصلاح المناهج وتطويرها، ضمن رؤى ومحاولات التأصيل التي تقوم بها بعض المؤسسات الأكاديمية والعلمية السودانية. ويعد البحث من باب الإشارة والتلميح- مقارنة نظرية لبعض محاولات التأصيل بتقييم وتقويم تجربة جامعة القرآن الكريم وتأصيل العلوم؛ والمعوقات التي تعترض بناءها وتطويرها لمناهج مؤصلة وتقديم مقترحات وحلول لمعالجة الخلل لتلك التجربة.

استخدم الباحث المنهج الوصفي التحليلي والمنهج المقارن، والمقابلات الشخصية، وتوصل للعديد من النتائج منها معرفة كافة المعوقات التي تعيق بناء منهج مؤصل، ثم وضع بعض الدراسات الكافية لمعالجة هذه المعوقات.

  • Performance evaluation of three different types of local evaporative cooling pads in greenhouses in Sudan

Abstract This study was conducted in Date Palm Technology Company Limited, Shambat, Khartoum
State. To evaluate performance of three types of evaporative cooling pads for greenhouses
(celdek pads, straw pads and sliced wood pads), as compared to the conditions outside the greenhouses
(control), for pads. Performance evaluation includes environmental parameters (temperature
and relative humidity at 8 am, 1 pm and 6 pm) and crop parameters (length and stem
diameter, leaves number and width, fruit length and diameter, fruit weight and dry matter and
yield). The results obtained for the temperature at 8 am showed that there was no significant difference
(0.05) inside the greenhouses, while a high significant difference between the conditions inside
and outside of the greenhouses was found. Significant differences were found at 1 pm and 6 pm
between all treatments as compared to the conditions outside the greenhouses, and the results
obtained for relative humidity showed high significant differences at 8 am and 1 pm inside the
greenhouses and between inside and outside the greenhouse, respectively, while there was no significant
difference at 6 pm inside the greenhouses and between inside and outside the greenhouses. On
the other hand, the results obtained for crop parameters showed that there were significant differences
between all parameters inside the greenhouses and outside the greenhouses; however, the
greenhouses with sliced wood pads gave the highest yield and the greenhouses with straw pads gave
the least and conditions outside gave the lowest.
This study indicated that the sliced wood pads are better than the other evaporative cooling pads

  • Effect of Land Preparation on Soil Physical Properties and Faba bean (Vicia faba L.) Yield and Yield Components in Eldaba, Northern State, Sudan

Faba bean is the most important food legume and cash crop in Sudan. Mature seeds of faba bean are good sources of protein, starch, cellulose, vitamin C and minerals. It is grown as a winter crop under irrigation, almost exclusively in northern parts of the country where suitable agro-climatic conditions prevail. The experiment was conducted in Northern State at Eldaba, Sudan (latitude 180 03’ N and longitude 300  57’ E) for two seasons (2008/2009 and 2009/2010). The objectives of the research were to examine the effect of different tillage methods on soil physical properties (soil bulk density and infiltration rate) and yield and yield components of faba beans (plant height, pods per plant, seeds per plant, 100 seeds  weight and grain yield.)  . A randomized complete block design (RCBD) with eight treatments and four replications were used to evaluate the production of faba bean. The tillage implements used in the experiment were: moldboard plow plus ridging, disk plow plus ridging, chisel plow plus ridger, moldboard plow plus disk harrow plus leveling plus ridging, disk plow plus disk harrow plus leveling plus ridging, chisel plow plus disk harrow plus leveling plus ridging, animal plow (traditional plow) and no  tillage as control. The statistical analyses showed that there was a significant difference between tillage treatments. Chisel Ploughing plus harrowing plus leveling plus ridging treatment had the lowest values of bulk density (1.20 g/cm3 ) at depth of 0-20 cm and )1.21 g/cm3(  at depth of 20-30 cm. Results showed that, the geatest plant hight (147.5 cm) was recorded for the tillage treatment chisel plow plus disk harrow plus leveling plus ridging followed by tillage treatment moldboard plow plus disk harrow plus leveling plus ridging (133.5 cm) and disk plow plus disk harrow plus leveling plus ridging (129.4 cm). The results showed that the highest grain yield was obtained by using tillage treatment chisel plow plus disk harrow plus leveling plus ridging (7432 kg/ha and 7366 kg/ha), which was increased by 44% and 28% greater than the control in the first season and second season, respectively. The results indicated that grain yield of faba bean was directly affected by land preparation. Chisel plow plus disk harrow plus leveling plus ridging is the most appropriate tillage package for faba bean land preparation.
