    The objectives of this work were to study the quality characteristics of wheat (Triticum aestivum L.) cultivars grown at three locations and to evaluate their performance in bread making. Proximate analysis, hectoliter weight, thousand kernels weight, gluten quantity and quality, falling number and sedimentation values were determined for 20 wheat cultivars grown in three locations in Sudan (Medani, Hudeiba and Dongola) compared with Canadian wheat flour. The best six cultivars were selected and subjected to more detailed study. The results showed significant (P≤0.01) differences in the quality tests among locations and genotypes. The results showed that cultivar KAU2* CHEN/BCN.CMB had the highest protein content when grown at Hudeiba (14.06%) and Dongola (13.87%). This high protein content was accompanied by high gluten (44.06% and 38.38%, respectively). Cultivar RGO/SERI/ TRAP// Bow grown in Hudeiba had the highest wet gluten (45%) and water absorption. Generally, increase in hectoliter weight was accompanied by increase in protein content. The highest dough development time was recorded for cultivar PYT # 23 (DW R39 × CONDOR “S”) 14P×T grown in Dongola. The same cultivar when grown in Medani had the highest dough resistance to extension. In Sudanese wheat flour, location has great effect on the molecular weight of the protein. The highest molecular weight was recorded for cultivar PYT #23 (DWR39 × CONDOR “S”) 14 P×T grown in Dongola, while the lowest value was recorded for cultivar CONDOR “S”/ 14PYT// DWR39 grown in Medani. Cultivar TEVEE “S”/ SHUHA “S” and PYT# H23 (DWR39×CONDOR “S”) 14P×T grown in Medani and cultivar IHSGE#20 grown in Dongola could be classified as good cultivars for bread making as they have high molecular weight and loaf bread specific volume. Cultivars RGO/ SERI/ TRAP// Bow and CONDOR “S”/ 14PYT// DWR39 grown in Medani are preferred for cakes, cookies, crackers and flat bread for their weak dough. The highest binding ability of starch to SSL and EMG was shown by cultivars RGO/ SERI/ TRAP// Bow and TEVEE “S”/ SHUHA “S” at all locations which indicates that starch binding ability to surfactants is controlled mostly by genetic factors rather than location. α- amylase activity was low for all wheat grown at different locations in Sudan due to low humidity at maturity and harvest time

    The objectives of this study were to investigate the nutritional value and quality of the sorghum bread (kisra) supplemented with pumpkin seed kernels flour. Proximate analysis of pumpkin seed kernels flour and production of Sudanese sorghum bread (kisra) supplemented with various ratios (5%, 10% and 15%) of pumpkin seed kernels flour were carried out. Energy values, contents of minerals and amino acids were determined for raw flour of pumpkin seed kernels, sorghum flour and their supplemented kisra product. The most significant (P≤0.05) effect of supplemented kisra was the increase in protein content from 10.6% for the control kisra to 12.6%, 14.7% and 16.5% for kisra supplemented with 5%, 10% and 15% pumpkin seed kernels flour, respectively. The contents of crude fiber, ash, moisture and fat of the supplemented sorghum kisra were also increased, but the content of carbohydrate was decreased as a result of supplementation. The replacement of sorghum flour with different ratios of pumpkin seed kernels flour resulted in a concomitant increase in the energy value of the kisra produced. Minerals content significantly (P≤0.05) increased especially K from 17.07mg/100g in control kisra to 18.5, 19.6 and 20.4mg/100g, P from 206.1mg/100g in control kisra to 240.6, 253.6 and 266.8mg/100g and Mg from 9.6mg/100g in control kisra to 11.6, 13.8 and 15.5mg/100g in kisra supplemented with 5%, 10% and 15% pumpkin seed kernels flour, respectively. Amino acids content of kisra supplemented with 5%, 10% and 15% pumpkin seed kernels flour also increased especially lysine from 24.9mg/100g in control kisra to 55.5mg/100g, 58.7mg/100g and 64.1mg/100g protein and thrionine from 38.9mg/100g in control kisra to 56.2mg/100g, 80.9mg/100g and 85.4mg/100g protein, respectively. The sensory evaluation revealed that the supplemented sorghum kisra was highly accepted by the panelists at 10% pumpkin seed kernels flour supplementation. The high amount of protein and minerals especially P, Mg, K and Fe as well as limiting amino acids lysine and thrionine reinforced the usefulness of pumpkin seed kernels flour for supplementation of sorghum flour

    An experiment was conducted in a farm at Soba Alhila, Khartoum, to investigate the effect of untreated sewage water on growth, weight and quality of two forage sorghum cultivars (Abu Sabein and Pioneer). The treatments were 100% sewage water, 75% sewage water with 25% pure water, 50% sewage water with 50% pure water, 25% sewage water with 75% pure water and 100% pure water. The treatments were arranged in a completely randomized design with four replications. The results showed that all growth attributes, fresh and dry weight per plant increased with increase in the ratio of sewage water in the irrigation water. Pioneer significantly exceeded Abu Sabein in plant height, stem thickness, leaf area, fresh weight per plant and dry weight per plant, but the difference in the number of leaves per plant between the two cultivars was not significant. Crude protein increased and crude fiber decreased with the increase in sewage water percentag

    Mapping Vegetation Degradation in Sudan Using NDVI data (1993-2003)

    Desertification is a main environmental problem in Sudan. Due to the spatial nature of desertification, remote sensing (RS) and geographic information system (GIS) technologies are appropriate tools of providing practical and real time analysis capabilities, which could play an important role in assessing and monitoring desertification. The normalized difference vegetation index (NDVI) data source in the present study was the image archive covering East Africa between 1993 and 2003. The different change classes of NDVI values over the study period were calculated and mapped, using RS and GIS data. The results showed that the calculated areas of different change classes of NDVI, throughout the study period, reflected the variations in the vegetation cover in terms of decreased and increased areas. Most of the unchanged areas are related to desert areas in Northern Sudan, the permanent tree cover (woodland/forest) areas in Southern Sudan and rangelands. The analysis identified the following three areas where degradation has occurred: (1) Al Gedarif, Sennar, Gezira, White Nile, and Kassala states, which are the main rainfed mechanized crop production areas, (2) areas around major oil fields, (3) areas in Western Equatoria, Bahr Eljebel, Jonglei and South Darfur states around the main towns (Yambio, Yei, Juba, and Nyala). Area having increased vegetation cover over the last 10 years was 9.81% (244500.6 km²) of the total area of Sudan. The unchanged areas are related to desert areas and semi-arid areas in North Sudan where the primary perennial vegetation cover that have existed for decades and composed of slow growing Acacia species, while the unchanged areas in Southern Sudan (Wood land/Forest) the trend could be attributed inaccessibility for mechanized croplands agriculture, firewood collectors and charcoal production

    Infectious and emerging diseases are major constraint for camel health and production in Africa and Asia. The accurate diagnosis of these diseases is central in their effective control. Traditionally, histopathology, virus isolation in cell culture or embryonated eggs, immunodiffusion and immunofluorescent tests and electron microscopy have been used for diagnosis of camel viral diseases, but recently molecular techniques are increasingly replacing them. The aim of the present study was to review the main current and new molecular diagnostic techniques for diagnosis of some camel viral diseases; namely, camelpox, camel contagious ecthyma, camel papillomatosis and morbillivirus infection. The experience of the Virology Laboratory at the Department of Microbiology, Faculty of Veterinary Medicine, University of Khartoum during 2003- 2010 on diagnostic application of gel-based polymerase chain reaction (PCR) and partial gene sequencing, including postgraduates research work on these important camel diseases are summarized and discussed. The performed PCR assays enabled rapid and early laboratory confirmation and molecular differentiation among the causative viruses as well as genotyping camel papilloma virus for the first time. The contribution of these achievements to the development of the animal production sector in the Sudan is highlighted
