Effects of different levels of sugar beet roots based concentrates on the performance of Tagger male kids

    High meat demand in the Sudan enhanced improvement of goat meat production. Tagger is a promising meat breed due to good conformation and high meat quality. Nutrition is a main constraint for goat meat production. Sugar beet is introduced into the Gezira State with no information on effects of dried sugar beet roots (DSBR) based concentrates level on Tagger kids performance, carcass characteristics and meat composition. Twelve Tagger males of 6 months old were housed in individual pens, divided into 3 groups, each with 4 animals and allocated at random to the experimental diets. They were weighed weekly for 8 weeks with a two weeks preliminary period. They were fed groundnut haulm (GNH) ad lib. in two equal meals at 8.0 am and 4.0 pm and refusals were collected and weighed daily. The animals were fed different levels of DSBR based concentrates: 0 (control), 150g and 300g, in two equal parts before GNH meals. The concentrates contained 68% DSBR,15% groundnut cakes, 15% sunflower cakes, 1% salt and 1% oyster shell. Samples of feeds and refusals were stored for laboratory analysis.  Resultd showed that groundnut haulm (30% CP, 8.8% CF, 4.8% ash and 48.2% NFE) had better proximate analysis than refusals which generally improved with concentrates levels. Dried sugar beet had 12.9% CP, 11.0% CF and 59.25% NFE and the concentrates had 42.25% CP, 2.0% CF and 49.5% NFE. Overall mean BW generally increased with concentrates level (10.78, 10.9 and 12.19kg at 0, 150 and 300g, respectively), but  not significantly different. Overall mean daily feed intakes varied with concentrates level and were 1550.89, 1187.46 and 1545.67g at 0, 150 and 300g concentrates, respectively, and were significantly least in animals fed 150g concentrates. Weekly weight gain generally increased with concentrates level in all weeks and was highest in animals fed 150g concentrates with no significant effects for concentrates level. It was 0.55, 0.68 and 0.60 kg at 0, 150 and 300g concentrates, respectively. It is recommended to use DSBR based concentrates in fattening Tagger kids.     حفز ارتفاع الطلب  على اللحوم وأسعارها في السودان تحسين لحوم الماعز. تعتبر التقر سلالة واعدة لإنتاج اللحوم لجودة القوام ونوعية اللحم.  إلا أن التغذية من المعوقات الرئيسة لإنتاج لحوم الماعز.  أدخل بنجر السكر لولاية الجزيرة ولا تتوفر معلومات عن أثر مستوى جذر البنجر الجاف) ج ب ج (على أداء جديان التقر وصفات الذبيحة  وتركيب اللحم.  وضعت 12 من ذكور جديان التقر بعمر 6 أشهر في حظائر فردية  وقسمت الى 3 مجموعات بكل منها 4 حيوانات  ووزعت عشوائيا على أعلاف الدراسة. وزنت الحيوانات أسبوعيا لمدة 8 أسابيع منها أسبوعين فترة إعدادية. أعلفت الحيوانات تبن الفول السوداني )ت ف س) حسب الرغبة في وجبتين متساويتين عند الثامنة صباحا والرابعة مساء وجمع ووزن العلف المتبقي.  كما أعلفت الحيوانات مستويات مختلفة من عليقة مركزة ترتكز على )ج ب ج  (عند صفر( الشاهد), 150 و300جم في جزئين متساويين  قبل وجبتي ت ف س. احتوت العليقة المركزة على 68% ج ب ج و15%  امباز فول سوداني و15%  تبن زهرة الشمس و1% ملح و 1% صدف  حفظت عينات من  الأعلاف والعلف المتبقي للتحليل المعملي.  حُللت المعلومات إحصائيا باستخدام تحليل التباين واستخدم اختبار دنكن لفصل اختلافات المتوسطات. كان  ت ف س (  30% بروتين خام ، 8.85 ألياف خام، 4.8% رماد و 48.2% جزء خالي من النتروجين) أحسن في التحليل التقريبي من المتبق.والذي تحسنت نوعيته بارتفاع مستوى العليقة المركزة. كان تركيب  ج ب ج 12.95 % بروتين خام ، 11% الياف خام و 59.25% جزء خالي من النتروجين .وتركيب العليقة المركزة  42.25 % بروتين خام ، 2% ألياف خام و 49.5% جزء خالي من النتروجين .  زاد متوسط الوزن الكلى مع زيادة العليقة المركزة (10.78 ،  10.9 و 12.19عند صفر و 150 و 300 جم عليقة مركزة على التوالي بدون فروقات معنوية .

The Sudan Peritoneal Dialysis Program: Three Years of Momentum

Introduction: End stage renal disease (ESRD) is a significant social and economic burden on Africa. Continuous ambulatory peritoneal dialysis (CAPD) was introduced as a national service in the Sudan three years ago. An overview of the Sudan Peritoneal Dialysis Program is presented. Review: As a national scheme, the Sudan PD program was sequentially launched in seven centers in Sudan. CAPD was the modality exclusively utilized. The total number of patients enrolled by July 2008 was 232. Patients' mean age was 43 years, 23.5% were children, 63% were males, and 19% were diabetic. PD was the initial dialysis modality for 54.7% of patients, 43.5% were referred from HD, and 1.9% had a failed kidney transplant. The majority of patients (62.3%) chose PD as the preferred dialysis modality, while the remainder were referred from HD to PD because of vascular access problems or hemodynamic instability. One third of patients required assisted PD, and 17% needed urgent initiation of dialysis. The cumulative peritonitis rate was one episode per 10.8 patient months. Touch contamination, urgent initiation of dialysis and execution of dialysis by family members other than trained helpers were among the identified predisposing factors. Conclusion: The establishment and operation of the Sudan PD program over the past three years have indicated that it is a promising project with multifaceted success. There is, however, an ongoing need for retraining of patients and staff. Early selection and careful preparation for potential PD candidates is also of vital importance to reduce the need for urgent dialysis initiation. Key words: peritoneal dialysis, CAPD, renal replacement therapy, Sudan, Afric

Response of Banana "Williams Hybrid" to Nitrogen, Phosphorus and Potassium Fertilization

Field experiments were conducted at the National Institute for Promotion of Horticultural Exports (NIPHE) research farm during the period of 2001 to 2002 to determine the effects of nitrogen, phosphorus and potassium levels on growth parameters, earliness, nutrient uptake, yield and yield components of "William's hybrid" banana cultivar. Treatments included 5 N levels (0, 69, 138, 207 and 276g N/mat/year), 2 P levels (0 and 20 g P/mat/year) and 2 K levels (0 and 41 g K/mat/year) . The treatments were arranged in a randomized complete block design with 3 replications. Banana growth, yield and yield components were significantly increased by N and K application. The highest vegetative growth parameters, yield and yield components were obtained with the application of 207 g N/mat/year in combination with 41 g K/mat/year. Application of N in combination with K also resulted in a significant reduction in the period from plant-ing to shooting and from shooting to fruit maturation. The shortest number of days to shooting were obtained with the application of 276 g N/mat/year. Application of N, P and K also resulted in increased leaf N, P and K contents. Application of P alone or in combinations with N and K had no significant effects on growth or yield parameters

Effects of nitrogen source, rate and foliar application on some leaf mineral nutrient contents and yield of “Sinnari” sweet oranges (Citrus sinensis L.) in the River Nile State, Sudan

      Sweet orange production in the Sudan is characterized by low yield and poor fruit quality. This research was aimed at determining the effects of nitrogen source, rate and foliar application on some leaf mineral nutrient content and yield of “Sinnari” sweet oranges in  the River Nile State during 2010/11 and 2011/12. Nitrogen sources were urea (100%), sheep manure (SM) (100%), or a combination of them (50% each), beside Wuxal foliar fertilizer. Nitrogen rates were 0, 43 and 86 kg N/ha. Treatments were arranged in a randomized complete block design with three replicates and 2 trees/plot. Results showed that nitrogen sources and rates were effective in increasing leaf nitrogen content and the highest values were obtained by the application of 86 kg N/ha using urea (100%) or a combination of urea and sheep manure. Application of Wuxal foliar fertilizer resulted in a significant increase of Zn and Fe leaf contents and total yield. Nitrogen source had significant effects on yield components and total yield. The highest values were obtained by a combination of urea and sheep manure or 100% urea, and the lowest values were recorded for 100% sheep manure. Nitrogen rate of 86 kg N/ha resulted in the highest yield components and total yield. It is recommended to fertilize sweet orange trees in the River Nile State with a combination of urea and sheep manure at the rate of 86 kg N/ha (12.4 kg SM/tree and 0.5 kg urea/tree) in addition to Wuxal foliar fertilizer

Effects of Ethrel Application and Packaging on Mango Fruit Quality

    Experiments were conducted at the National Institute for the Promotion  of Horticultural Exports, University of Gezira, Wad  Medani, Sudan, during May 1997 and 1998 to investigate the effects of Ethrel and polyethylene packaging on mango fruit quality. Mango fruit quality, Mango fruits were  harvested at the mature-green stage and treated with Ethrel or  left as control. Fruits were packed in either intact or perforated polyetlhylene packages or left unpacked. The experiments were set up in a completely randomized design with three replications. Ethrel treatment accelerated  the rate of fruit ripening as shown by an increase in total soluble solids, yellowing and a decrease in fruit firmness and starch content Fruits packed in intact polyethylene packages resulted in the  lowest weight loss, followed by those packed in perforated films, whereas unpacked fruits showed the highest weight loss and lowest quality manifested in shriveling and deterioratio

Effect of cultivar, packaging treatments and temperature on post-harvest quality of okra

ABSTRACT    Okra is one of the most popular vegetable crops in Sudan. The introduced cultivars such as Pusa Swani and Clemson Spineless have smooth pods and more adapted to the winter conditions of central Sudan. However, the local cultivar, Khartoumia, has hairy pods and not acceptable in international markets. Okra pods are highly perishable and subject to shriveling especially under the hot arid conditions of central Sudan. Therefore, the objective of this study was to determine the effect of packaging and temperature on the shelf life of okra pods of three introduced cultivars. Treatments consisted of three okra cultivars, namely, Clemson Spineless, Pusa Swani and Mahyco (hybrid); packaging treatments consisted of packing okra pods in cartons lined with intact polyethylene film, perforated polyethylene film or in cartons only and storage temperatures were 140C and 320C. Results showed that pods of the  cultivar Mahyco had the lowest weight loss, retained good colour and had the least decay and rot. Packaging of okra pods in intact or perforated polyethylene film and storing at 140C reduced weight loss and resulted in the best pod colour compared to the control. Packaging in perforated polyethylene film and storing at 140C resulted in the lowest incidence of decay and rot and best overall quality of pods. It is recommended to package okra pods in perforated polyethylene film and ship them to markets at 140C

Current status of sweet orange (Citrus sinensis L.) orchards in the River Nile State, Sudan

ABSTRAC     Production of sweet oranges in the Sudan does not cover domestic needs and sweet oranges are currently imported from Egypt, Iran and South Africa to satisfy the increasing demand. Hence, there is a need to investigate factors involved in the decline of sweet orange trees in one of the most important States for orange production in the Sudan. This research aims to study and evaluate different agronomic practices contributing to the prevailing sweet orange performance in the River Nile State, Sudan. A questionnaire and interviews with 120 sweet orange growers from Ketiab, Zeidab and Gandato citrus projects indicated that 75.8% of the farmers have orchards less than 2.9 ha. Low yielding cultivars such as “Sinnari”, the local selection (Baladi), Hamlin and Nori 16 dominate in the areas, 96.7% of the trees were budded on sour orange rootstocks, 85.8% of the seedlings were budded in private nurseries using bud wood collected from non-certified mother trees from private orchards. All sweet oranges were grown with other fruit species in 100% of the orchards, 80.8% used flat surface irrigation. There is no fixed fertilizer program. The type and quantity of chemical and organic fertilizers varied with different growers. No foliar fertilizers were used and nutrient deficiencies of Zn, Fe and Mn were observed in most orchards. Extension services for citrus production are highly needed for improvement of yield and quality of sweet oranges in the River Nile Stat

Effects of nitrogen source and effective micro-organisms on vegetative growth of shrubs of selected grapefruit (Citrus paradisi Macf) cultivars

   Grapefruit (Citrus Paradisi Macf.) is one of the most important citrus fruits in the Sudan. It can be successfully grown throughout the country where there are suitable soils and sufficient water to sustain tree growth. The objectives of this study were to find out the effects of different nitrogen sources, effective microorganisms (EM) and their combinations on the vegetative growth of shrubs of selected grapefruit cultivars. A field experiment was carried out at Umbarona, Wad Medani, Gezira State, Sudan, latitude 14.38 N, longitude 33.48 E and altitude 409 masl, in June 2012. Treatments consisted of three grapefruit cultivars: Marsh Seedless, Red Blush and Shamber. Fertilizer treatments were urea (100%), chicken manure (100%), urea with chicken manure (50% each), urea with EM, chicken manure with EM, urea (50%)+ chicken manure (50%)+ EM and unfertilized control. All fertilizer treatments were applied at the rate of 43 kg N/ha. Treatments were arranged in a split- plot design with two replicates. Grapefruit cultivars were allotted to the main plots and fertilizer treatments to the sub-plots. Data were collected on plant height (cm), stem diameter (cm), number of new branches, length of new branches (cm) and diameter of new branches (cm). Results showed that Marsh Seedless cultivar had the most vigorous vegetative growth compared to the other two cultivars. The results showed that the combination of urea, chicken manure and EM significantly gave the highest vegetative growth values, followed by chicken manure with EM, urea with chicken manure, urea with EM, urea alone, chicken manure alone and the least values of growth parameters were recorded for the unfertilized control. It is recommended to grow Marsh Seedless grapefruit cultivar and fertilize it with a combination of urea, chicken manure and EM.         يعتبر القريب فروت من أهم ثمار الحمضيات في السودان ويمكن زراعته بنجاح في جميع أنحاء البلاد حيثما توفرت التربة المناسبة والمياه الكافية لنمو الأشجار. أجريت تجربة حقلية في ام بارونة، واد مدنى ولاية الجزيرة، السودان. تهدف هذه التجربة لمعرفة تأثير مصادر النتروجين المختلفة والكائنات الحية الدقيقة الفعالة ومزجها مع بعضها البعض على النمو الخضري لشجيرات أصناف منتخبة من القريب فروت. تضمنت المعاملات ثلاثة أصناف من القريب فروت وهي مارش  ورد بلش وشامبر وسبعة معاملات أسمدة وهي  اليوريا، وزرق الدواجن، يوريا مع زرق الدواجن، يوريا مع الكائنات الحية الدقيقة الفعالة، زرق الدواجن مع الكائنات الحية الدقيقة الفعالة، يوريا مع زرق الدواجن مع الكائنات الحية الدقيقة الفعالة والشاهد. تمت إضافة الأسمدة لكل المعاملات بمعدل 43 كجم نتروجين للهكتار. صممت التجارب بطريقة القطع المنشقة بحيث كانت أصناف القريب فروت هي القطع الرئيسة ومعاملات النتروجين هي القطع الثانوية. جمعت بيانات عن طول النبات (سم) وقطر الساق (سم) وعدد الأفرع الجديدة وطول الفرع (سم) وقطر الفرع (سم). أوضحت النتائج أن الصنف مارش أعطى أعلى نمو خضري مقارنة بالصنفين رد بلش وشامبر. الخليط بين سماد اليوريا وزرق الدواجن و الكائنات الحية الدقيقة الفعالة  أعطت أعلى معدل للنمو الخضري ويليه زرق الدواجن والكائنات الحية الدقيقة الفعالة ثم اليوريا والكائنات الحية الدقيقة الفعالة ثم اليوريا وزرق الدواجن ثم زرق الدواجن لوحده ثم اليوريا لوحده وأدنى معدلات  النمو كانت في الشاهد .  يوصى بزراعة الصنف قريب فروت مارش وتسميده بخليط من اليوريا وزرق الدواجن والكائنات الحية الدقيقة الفعالة

Effect of plant spacing and pruning on vegetative growth, yield and fruit quality of introduced mango cultivars

   Kitchener is the most extensively cultivated mango cultivar in the Sudan. However, this cultivar is not popular in export markets due to its high fiber content. Hence, internationally popular mango cultivars have been recently introduced to the Sudan from South Africa. They  include Tommy Atkins, Kent, Keitt, Haden and Sensation. An experiment was conducted in Kamleen nursery, Gezira State, Sudan, during June 2008 to May 2011, to investigate the effects of plant spacing and pruning on vegetative growth, yield and fruit quality of these introduced mango cultivars compared to the local cultivar, Abusamaka . The trees were planted at a spacing of 5x5m and 10x10 m and subjected to three types of pruning, namely, pruning to two branches, three branches, tip pruning and control. Treatments were arranged in a split-plot design with three replicates. Plant spacing was assigned to the main plots and pruning treatments to the sub-plots. Results showed that the wider spacing resulted in significantly larger canopy diameter and larger number of fruits per tree than the closer spacing in all cultivars and seasons. However, the closer spacing resulted in significantly larger number of fruits/ha and  higher total yield/ha than the wider spacing due to the larger number of trees/ha. Pruning of mango trees to three main branches resulted in significantly the highest yield components and total yield, followed by two branches, tipping and the lowest yield components were produced by the un-pruned control. The introduced mango cultivars had significantly more vigorous vegetative growth, earlier in flowering, higher yield components and total yield and better fruit quality than the local cultivar Abusamaka. It could be concluded that the introduced cultivars Tommy Atkins, Kent and Keitt are promising cultivars to be grown in the Sudan using the high density planting system and pruned annually for high production of good quality fruit.        يعتبر الصنف كتشنر أكثر أصناف المانجو انتشاراً في السودان ولكنه غير مرغوب في أسواق الصادر نسبة لاحتوائه على نسبة عالية من الألياف. لذلك فقد تم استجلاب بعض الأصناف المرغوبة عالمياً من جنوب أفريقيا ، وقد شملت هذه الأصناف تومي أتكنز ، كنت ، كييت ، هادن وسنسيشن. أجريت التجربة بمشتل الكاملين ، ولاية الجزيرة ، خلال الفترة من يونيو 2008 حتى مايو 2011م لمعرفة تأثير أبعاد الزراعة والتقليم على النمو الخضري ومكونات الانتاج والانتاجية  ونوعية الثمار لهده الأصناف المستوردة مقارنة بالصنف المحلى أبوسمكة. زرعت الأشجار على مسافات 5x5 م و10x 10 م وتم تقليمها بثلاثة طرق للتقليم على النحو التالي : تقليم على فرعين وتقليم على ثلاثة أفرع وتقليم القمم النامية للأفرع وغير مقلمة للمقارنة. استخدم تصميم القطع المنشقة بثلاث مكررات، حيث اسندت القطع الرئيسية لأبعاد الزراعة والقطع الفرعية لطرق التقليم. اظهرت النتائج أن مسافات الزراعة 10x10م اعطت معنوياً أفضل نمو خضري وأكبر عدد الثمار للشجرة الواحدة بالمقارنة مع 5x5م فى كل  المواسم. أبعاد الزراعة  5x5 م اعطت معنوياً أعلى عدد للثمار وأعلى انتاجية للهكتار نسبة للعدد الكبير من الاشجار فى الهكتار. تقليم أشجار المانجو لثلاثة أفرع أعطى معنوياً أعلى انتاج يليه التقليم لفرعين ثم تقليم القمة وأدنى انتاجية كانت فى الاشجار غير المقلمة. الأصناف المستوردة اعطت معنوياً أفضل نمو خضري وأعلى انتاجية وأفضل نوعية للثمار بالمقارنة مع الصنف المحلي أبوسمكة. خلصت الدراسة إلى أنّ الاصناف المستوردة تومي اتكنز وكنت وكيت هى أصناف واعدة يمكن زراعتها فى السودان بطريقة الزراعة المكثفة وتقليمها سنوياً للحصول على أعلى انتاج من الثمار عالية الجودة

Estimation of supply and demand functions of the major food security crops in the Sudan (1974- 2004)

This study aimed at estimating the supply and demand functions and measuring the food consumption gaps of the main food crops, namely sorghum, wheat and millet. Descriptive statistics and backward regret-ssion analysis were used as tools of analysis. Results showed that the quantity of food crops produced was far below the real needs for local consumption. Moreover, self-sufficiency ratio has declined from 100 % in 1981/1982 to 72.6% in 2000 /2001, indicating positive trend in the food consumption gap. Regarding sorghum crop, results showed that the most important factor affecting the supply of sorghum was the lagged producer price whereas the most important factors affecting demand for sorghum were consumer price of sorghum and per capita income. Results showed that the most important factors affecting the supply of wheat were the producer price of sorghum and the producer price of cotton whereas the most important factor affecting demand for wheat was the consumer price of sorghum. The millet crop was affected by the lagged producer price and consumer price of millet supply and demand functions, respectively. The results of this study indicated that, in a national sense, Sudan is food insecure during the period 1980/81-2004/2005. The shift in consumption habits towards wheat is highly responsible for the food insecurity. &nbsp
