  • Chicken manure, N and P Fertilizers Effects on muskmelon (Cucumis melo Var. reticulatus Naud) growth, soil and plant nutrient contents ( Eltayeb M. Abdelmalik, Ahmed M.Z. Ibrahim and Mohamed E. Elkashif)

Two experiments were conducted during the summer of 2000 and winter of  2000/2001, at the National Institute for the Promotion of Horticultural Export (NIPHE) research farm, Wad Medani, Sudan. The objective was to study the effects of chicken manure, N and P fertilizers on muskmelon growth, soil and plant nutrient contents. The treatments were four levels of chicken manure ( 0, 4.5, 9 and 18 t/ha), two levels of  N (0 and 55 kg N/ha) and two levels of  P ( 0 and 55 kg P2O5 t/ha) arranged in a randomized complete block design with three replications. The results showed that muskmelon vegetative growth, total soil N, available P and plant uptake of  N and P were significantly increased with the application of chicken manure in combination with N and P. The highest values of these parameters were obtained with the application of 18 tons of manure/ha in combination with 55kg N and 55kg P2O5 /ha.

  • Effects of Irrigation Intervals, Nitrogen and Phosphorus on Grain Yield and Biomass of Wheat ( Lubna M. Musa, Eltayeb M. Abdelmalik, Muawia E. Hamad and Ahmed A. Salih)

This study was conducted for two successive seasons of 1998/1999 and 1999/2000, at the Gezira Research Station Farm, Agricultural Research Corporation, Sudan, to investigate the effects of irrigation interval, nitrogen and phosphorus levels on wheat (Triticum aestivum L.) yield and yield components. The study consisted of three irrigation intervals (7,14,21 days), three N levels (0, 43 and 86 kg N/ha) and two P levels (0 and 43 kg P2O5/ha). Treatment were arranged in a split-split plot design with three replications. Results showed that the irrigation intervals of 7 and 14 days had positive effects on wheat grain and total dry matter yield as compared to the 21 days irrigation interval which negatively affected these parameters. Plants of the latter treatment were dwarf with thin stems and matured earlier resulting in low grain and biomass yield. The study, also, showed that the highest wheat yield was obtained with the application of  N and P at the rates of 86 kg N and 43 kg P2O5/ha, respectively, with the irrigation interval of 7 days.

  • Effect of chicken manure n and p on yield and quality of musckmelon (Cucumis melo var. reticulatus Naud) (Ahmed M. Z. Ibrahim, Eltayeb M. Abdelmalik and Mohemed E. Elkashif)

Two experiments were conducted at the National Institute for the Promotion of Horticultural Exports (NIPHE) research farm, Wad Medani, Sudan, during the summer of 2000 and winter of 2000/2001, to study the effects of chicken manure, nitrogen and phosphorus on muskmelon yield and quality. The treatments were four levels of chicken manure (0, 4.5, 9 and 18t/ha), two levels of nitrogen (0 and 55kg N/ha) and two levels of phosphorus (0 and 55kg  P2O5/ha) arranged in a randomized complete block design with 3 replications the results showed that muskmelon growth, yield and quality were significantly affected by chicken manure, N and P application. The most vigorous plant growth, the highest fruit yield and the largest fruits with best netting and highest total soluble solids were obtained by the application of 18 tons of chicken manure with 55kg N and 55kg P2O5/ha.

  • Iron and Nitrogen Interactions in Groundnut Nutrition ( Zakia I. Ali, E. M. Abdelmalik, H. M. Babiker, V. M. Ramraj, A. Sultana, and C. Johansen)

A pot experiment was conducted to estimate the levels of iron (Fe) needed to correct Fe-deficiency chlorosis in groundnut grown in an alkaline soil and to study Fe x nitrogen (N) interactions in soil and plant and their associated effects on growth an yield. Four levels of Fe (0, 2.5, 10,and 25mg Fe kg-1 soil as Fe-EDDHA ) and two levels of N(0 and 100mg N kg-1 soil as NH4NO3 ) were applied factorially in completely randomized block design. Higher rates of 10 and 25mg Fe kg-1 caused a significant reduction in leaf area and aerial biomass accumulation irrespective of N treatment. The Fe x N interaction was significant for all of these parameters. Specific leaf area increased at higher levels of Fe application. Higher Fe levels induced symptoms suggestive of manganese (Mn) deficiency. This diagnosis was

  • دور مخرجات البحوث والدراسات التربوية والنفسية العلمية في التنمية المجتمعية بولاية الجزيرة، السودن دراسة ميدانية على عينة من مواطني الولاية بحاضرتها مدينة ود مدني، 2018))

هدفت هذه الدراسة إلى تسليط الضوء على  الدور الذي تؤديه مخرجات كل من البحوث والدراسات في المجال التربوي والنفسي في التنمية المجتمعية لمواطني ولاية الجزيرة، كما هدفت الدراسة إلى معرفة وتحديد المصادر التي تعمل على تقديم وعرض نتائج تلك البحوث والدراسات للمجتمع والوسائط التي تستخدمها في ذلك، اُستخدم المنهج الوصفي الاستقرائي في الدراسة وتم اختيار عينة عشوائية بسيطة قوامها (260) فرداً من  مدينة ود مدني حاضرة الولاية منهم (130) ذكور و(130) إناث، حيث طُبقت عليهم الاستبانة التي أُعدها الباحث خصيصاً لأغراض الدراسة، وقد اُستخدم برنامج الحزمة الإحصائية للعلوم الاجتماعية، SPSS لتحليل نتائج الدراسة، وكانت أهم النتائج: أن لمخرجات البحوث والدراسات التربوية والنفسية دوراً إيجابياً فاعلاً في التنمية المجتمعية لمواطني ولاية الجزيرة، وأن مجتمع ولاية الجزيرة يستفيد من البحوث والدراسات التربوية عبر أساتذة الجامعات في الولاية بنسبة (53.46%) وأخصائيي التربية وعلم النفس بنسبة (35.76%) وإعلاميي الولاية بنسبة (10.78%)، وذلك عبر البث التلفزيوني والإذاعي إلى جانب المحاضرات والندوات وصحيفة ولاية الجزيرة الأسبوعية وصحيفة جامعة الجزيرة الدورية، أوصت الدراسة بضرورة العمل على مد المجتمعات بأحدث نتائج البحوث والدراسات التربوية والنفسية بطريقة ممنهجة حتى يساهم ذلك في تطور المجتمعات ونموها.
