Item Diversity and cross inoculation abilities amongrhizobia isolated from different guar (C yamobsistetragonoloba (L.) Taub.) lines(ALNEELAIN UNIVERSITY, 2003-10) Maha Abdel hafeez Mohamed/\ hstract Ten R/1/zu/uiini lSUlillCs were isolated Iroin the root nodules olltcn guar lines. The isolates were authenticated each with ills respective host (line) of isolation. Cross-inoculation experiments revealed a wide range in the degree of line-isolate efliciency. The majority of guar lilies benefited from R/7/3!)/HIIIH inoculation. This was rellected in the high shoot dry weight and nitrogen content produced by the inoculated plants as compared to their respective non-inoculated controls. l\/licroscopical and biochemical characterization showed that all tested isolates were last growing, inicroaerophilic, acid producing, catalase and oxidase positive, they donlt absorb congo red, and were unable to grow on Glucose Pepton Agar (GPA). The isolates did not utilize citrate or ornithine and were also unable to produce HZS, lndole_ Acetoin or 3- ketolactose. All isolates were able to utilize most olthe tested carbohydrates as sole carbon sources and were also able to tolerate high salinity level (up to I92 gill), /\ntibiotic sensitivity tests showed a wide range oi‘ variations among the isolates. However, all tested isolates were lound to be resistant to Tetracycline and Ampicilin. Serologically, all isolates cross- agglutinated with each other indicating close serological alillinities among them. Summing up _ cluster analysis have separated the isolates into four groups that have included the following isolates: l- Group l: isolates /\22_ B4_ E51 l'l 5 and lll5. 2- Group ll: isolates D30 and ll2. 3- Group lll: isolate G7. 4- Group V: isolates C33 and lll5. i\ l ZItem STUDIES ON IMPROVING SALTED-FERMENTED FISH PRODUCTS IN SUDAN(ALNEELAIN UNIVERSITY, 2006-05) Ghada Ahmed El HajABSTRACT In attempts targeting preservation of fish and their products for consumption at subsequent times and places far away from the source, this programme was arranged for a number of preservation methods to address the issues. Those methods have duly included drying, salting, smoking, fermentation. . . etc. to give a good coverage for various types of fish. It arises from the above, that there is a need to evaluate traditional and improved methods of preservation to reach an acceptable product for the consumer. For the fiilfillment of the above, this programme was set to address the quality of fish from chemical, physical and biological viewpoint. Special emphasis was attached to salting and fermentation and their impact. However, the result of this study indicated that fresh samples of two species of fish Kawara (Alesles sp.) and Debs (Labeo sp.) during three seasons are comparable in both content and values. These values of change in varying degrees when subjected to different salt concentrations during short and prolonged time. General magnitude change between fi'esh and treated samples was obtained for both sp. Significant variations for all parameters of two species during the first l\twelve days of treatments were detected, It has to be emphasized that the sixth months marks the onset of fiirther deterioration. \Item A SimulAtion Model For Centre Pivot Irrigation system design and optimiza tion of operation(ALNEELAIN UNIVERSITY, 2008-10) Osama Osman Ali OsmanA Simulation Model for Centre Pivot Irrigation System Design and Optimization of Operation (Ph.D Thesis) Osama Osman Ali Osman Abstract: A computer simulation model was developed for the purpose ofthe design and optimization of the operation of centre pivot irrigation system. The model was written in Visual Basic 6.0 Programming Language. The model determines crop water requirement, irrigation scheduling, application rate, irrigation time, and system hydraulic parameters. It also evaluates the performance of the system when supplied with the required data. For verification of the model, field trials were carried out during the period December 2007 - July 2008 at four schemes using centre pivot irrigation systems. The schemes were Ras Al Wadi Al Akhadar Project- north Atbra town, El Bashair Company- south Al Damar town, Tala Company-north Shendi town and the Arab Company for Agricultural Production and Processing in Khartoum area. The schemes were growing alfalfa, except El Bashair company which was growing onion. Crop water requirement was estimated using the modified Penman equation and Penman-Monteith method. The program when supplied with required data can estimate the reference crop evapotranspiration and crop water requirement. The values of May 2008, obtained for reference crop evapotranspiration (ETo) by using the modified Penman equation were 8.7, 8.7, 8.6 and 8.4 mm/day, and by using Penman-Monteith method were 8.9, 8.9, 8.4 and 8.0 mm/day for Ras El Wadi Al Akhdar Project, El Bashair Company, Tala Company and the Arab Company for Agricultural Production and Processing, respectively. The values of April were close to May values, but in January, February and March Pemnan-Monteith gave lower values than modified Pemnan.The values obtained for predicted crop water requirement (ETc) by using the Xlllmodified Penman equation were 10.4, 9.1, 10.3 and 10.0 mm/day. and by using Penrnan-Monteith method were 10.6, 9.3, 10.0 and 9.6 mm/day for Ras El Wadi Al Akhdar Project, El Bashair Company, Tala Company and the Arab Company for Agricultural Production and Processing. respectively. The model determines the irrigation scheduling variables. The total available water in the root zone to be 300, 90, 300 and 345 mm. Readily available water (net depth) was 150, 45, 150, 173 mm. The gross water depth was 230, 69, 231 and 230 mm, irrigation time was 29, 9, 29 and 58 hours and the number oftotal irrigations during the month was found to be 5, 8, 5 and 5, for Ras El Wadi Al Akhdar Project, El Bashair Company, Tala Company and the Arab Company for Agricultural Production and Processing, respectively. The model also determines the system variables. Distance from pivot point to last tower was 380, 405, 332.5 and 468 m, application rate was 100, 48, 91and 42 mm/h, and maximum application rate was 128. 61, 116.5 and 59 mm/h. System capacity was 154, 179, 128 and 123 m3/h. Friction losses were 1.27, 1.43, 3 and 1.0 m for Ras El Wadi Al Akhdar Project, El Bashair Company, Tala Company and the Arab company for Agricultural Production and Processing, respectively. The model determines the coefficient of uniformity of systems, uniformity of distribution and scheduling coefficient. The coefficient of uniformity was 78, 79, 85, 79 and 77%. Uniformity of distribution was 68, 70, 78, 71 and 67%. Scheduling coefficient was 1.47, 1.43, 1.3, 1.41 and 1.49 for Ras E1 Wadi Al Akhdar Project, El Bashair Company, Tala Company, Arab Company for Agricultural Production and Processing and the Arab Company for Agricultural Production and Processing after changing sprinklers, respectively. The model can satisfactorily estimate crop water requirement, irrigation scheduling, system design variables and evaluate the performance of the system. XIVItem RAINW ATER HARVESTING TECHNIQUES FOR SOIL MOISTURE CONSERV ATION ON THE UPPER TERRACES OF THE WHTE NILE STATE (Sudan)(ALNEELAIN UNIVERSITY, 2004-12) ABDEL RAHMAN MOHAMED NOUR HAMIDABSTRACT Field experiments were conducted at Humra, Aba, and Kileikis, White Nile state, Sudan, on a sandy clay soil, following a randomized block design, to study the effect of water harvesting techniques namely: crescents, intersections, ditches and control treatments on some soil physical properties and soil moisture content. The soil moisture content was measured monthly immediately after the rainy season till the beginning of the next season during 2003/04 growing season. Also plant parameters of Acacia nilotica and Acacia tortilis transplants were measured monthly immediately after the rainy season till the next season. Direct rainfall was measured using rain gauges which were installed on the field. The results indicated that the water harvesting techniques affected the soil structure and soil physical properties specially on the upper layer (0-30 cm) which subjected to excavation tools and consequently the soil moisture content as a result of improving infiltration rate, porosity, field capacity and reducing rain water runoff. The results revealed that the crescents treatment was the best technique for improving porosity, infiltration rate, soil storage capacity and reducing runoff which led to a good performance of Acacia nilotica and Acacia tortilis transplants. The intersections techniques came next to the crescents in storage capacity and performance of the plants. Also the results showed no significant differences between ditches and control treatments. The results indicated that the Acacia nilotica transplants gave good results when the moisture content increased while Acacia tortilis transplants gave good results when the moisture content decreased.Item THE POTENTIAL OF SOME INDIGENOUS SOILMICROORGANISMS IN DEGRADATION OF THE INSECTICIDE ENDOSULFAN ALPHA AND BETA ISOMERS(ALNEELAIN UNIVERSITY, 2006) OSAMA EL GIALANI ELSAIDAbstract Nine soil types from sites with various levels and history of contamination by insecticides were chosen as inoculums sources for the present studies The presences of four groups of soil microorganisms in these soils were surveyed using selective media. The results indicated that organic nitrogen bacteria is more prevalent and found in all types of soils followed by inorganic nitrogen bacteria and actinomycetes, fungi and bacteria and actinomycetes which lives in poor media. Soil microorganisms isolated from the nine soil types showed great potential in degrading oi and B-endosulfan in selective media after l5 days of incubation. Generally the results indicated that microorganisms isolated from highly contaminated soils had greater potential in degrading the two isomers of endosulfan. The effects of soil microorganisms isolated from highly polluted soil, on half-lives of (1 and B- endosulfan under condition of selective and carbon free media were re-studied for longer period. The results showed significant decrease in half-lives ranging between 58.4 — 81.9% in (1- endosulfan compared to 35.5 — 71 .6% in B-isomer. The effect of fertilizer activator on enhancing the microbial growth and capability in degrading oi and B- endosulfan under soil conditions was studied. Results indicated that all activators caused significant increase in microbial counts especially the triple super phosphate. The accompanied reduction in half lives ranged between 20-73% with various levels of endosulfan sulphate generated. Microbial degradation at elevated concentration (500 mg/l) of endosulfan in carbon free was studied and the results showed that there were no significant differences in the reduction of half-lives between high (500 mg/1) and low (100 mg/1) concentration. Tolerant strains of bacteria and fungi from the soil of Rass Elfeel pesticide store (Mangil scheme) were isolated through consecutive exposure to elevated concentration of endosulfan under condition of carbon free media and the results showed that the most tolerant fungi (can tolerate up tol000 mg/l) was Aspergi//us fiuntgales while the most tolerant bacteria was Bacillus sp. The comparative degradation of endosulfan by tolerant strains and their parents was studied under condition of soil and carbon free media. Results showed that parent strains (present in large number) showed faster decrease in half lives compared to tolerant strains (few numbers). However tolerant strains might have greater potential if they find a chance to propagate in massive numbers. IllItem Effect of Feeding diffeent levels decorticated Cajanus cajan seeds on broiler performance as a replacement of sesame cake(ALNEELAIN UNIVERSITY, 2005-09) El Hafiz Abd-El Rahman HassanAbstract This study was conducted to assess the performance of broiler birds fed on decorticated Cajanus cajan (C. c) as a replacer to sesame cake. The study was conducted on deep litter in open houses pens at El Neelain Poultry Farm at Jebel Awlia during the period from 4'“ May to 22nd June 2005. 200 unsexed (Ross) broiler chicks were randomly distributed into batches of 40 birds per batch per dietary treatment. Birds were divided in to 4 replicates of 10 for each treatment of the five rations. Acontrol plus 4 rations containing 3%, 6%, 9%, and 12% of C.c. were fed. Parameters studied were feed intake, feed conversion ratio, weight again, livebody weight, dressed weight, edible parts weights, serum proteins and the economic appraisal. 12% incorporation followed by 9% gave the best results in all parameters studied. Serum proteins and ALT (Alanine Amino Interferase) were within normal levels indicating no ill health or diviation from normal. The economic appraisal showed that 12% followed by 9% gave the least cost per Kg of broiler meat. vm The study concluded that broiler birds can perform well and survive healthy when fed C.c. up to 12% incorporation in the ration. This supports the assumption that decortication improves feeding efficiency and performance of Cajanus cajan.Item Comparison of the nutritive value of Fessielfh i11 Hydrocynus spp and Schilbe spp(Neelain University, 2006) Egbal Osman AhmedAbstract The current fessiekh industry is based on traditional means of production. Those practices do not seem to have been based on scientific background. This work aims at the effects of various concentrations, through three treatments, for two species of freshwater fish, on the fessiekh product. Recent efforts have been focusing on the consolidation of positive and as much as possible the minimization of the negative results. Hydrocynus species and Schilbe species were used for fessiekh preparation by using different salt concentrations (20%, 25%and 30% w/w) for three treatments (i.e. different seasons). Chemical, microbiological and sensory characteristics were determined for fish before and after salting. Microbial investigation during salting of fish showed the initial microbial increase, which passed through a maximum that finally, decreased. Commercial fessiekh contained a higher microbial load than experimentally prepared one. ,' Commercial fessiekh and experimental one showed no variations of all parameters measured other than potassium, calcium and sodium. This varying bacterial count gives the product the flavor, appearance and taste. ' Chemical composition of the two species at clifferent salt concentrations in the three treatments indicated some losses of the nutritive value when compared with fresh state. While the moisture ranged from 81.92 to 72.9% in fresh fish, it dropped to 74.94 to 60.20%D.W. in salted fish. Values for protein. fat, crude fibre and ash were20.5 to18.9%, 2.2 to 1.4%, 1.9 to 1.0% &1.7 to 1.1% in fresh fish, while in salted fish values were19.57 to 16.54%, 1.62 to0.88%, 1.32 to 0.64%, and 10.21 to 13.86% D.W. respectively Effect of the three salt concentrations (20%, 25% and 30%) on the nutritive value of fessiekh product showed no significant variation, although the salt concentration at 20% gave better results than two other concentrations. 0 Effect of seasonality (temperatures 37, 30, 27"C) on the nutritive value of the two species showed significant difference, but winter season (27 ° C) gave good quality of product compared to higher degrees (i .e 37, 30°C). Comparative nutritive value of stored product “Fessiekh” for six months, showed lower nutritive value ; better time for marketing is from zero days to 30 days. 1' Taste panelists found product from ' fish fermentation treated with salt concentration at 20% more acceptable.Item تنمية الموارد الزراعية بولاية شمال كردفان ( حالة محافظة شيكان ) من 1999 - 2001(جامعة النيلين, 2001) انصاف ابراهيم الخليفة محمد احمدstreet This study deals with the Development of agricultural resources (soil , vegetation , and water and livestock in province, Northern kordofan state.

The study was based on primary data collected through field work survey , by using different methods and techniques including questionnaires, interview and direct observation beside. Secondary data , form sources official and non official interview and directed observation both published and unplished, were also utilized . ~ The study revealed that the province in its natural conditions is endowed with agreat base of renewable natural resources, that could meet the objectives of the human development in the area at present and the future, under conditions of sound and rational environmental management. However, the study Showed that sheikan province is presently suffering from acute problems of environment degradation . This is reflected negatively in the living conditions of the population. The histrorical relationship between man and his'environment, which was based on the harmony between man’s needs and the environmental condition, has also changed. The study reached to the conclusion that environmental degradation and changes in the relationship between man and his environment , in the province, are the result of closely interrelated factors.. Most important among these are: the accelerated rate of population growth on the prolonged periods of drought in Northern kordfan during the 1970s and 1980s , and the high rate of population dis placement from southern Sudan and Southern Korodofan State Caused byItem EFFECT OF FEEDING DIFFERENT LEVELS OF Cajanus cajan SEEDS (PIGEON PEA) ON PERFORMANCE AND MEAT QUALITY ATTRIBUTES OF MALE GOAT KIDS(Al Neelain University, 2009-03) Elhafiz Abd Elrahman HassanThis study was conducted to assess the performance and meat quality attributes of male Sudan Nubian goat kids fed diets containing different Cajanus cajan seed (pigeon Pea) levels as replacement of ground nut cake (G.N.C). The study was conducted in two experiments: Experiment (1): Thirty five young male Nubian goat kids 5-6 mouths old were purchased from the animal markets of Wad Madni, Elarebab. and Almadena Arad. transported to the small ruminant pens at the Faculty of Agricultural Technology and Fish Sciences Aneelain University in Jabal Awlia. The kids were very weak. emaciated, preweaned and the rumen were not well developed according to the farmers believe. Accordingly the farmers wean kids three days afier birth. After the adaptation period the animals were weighed, and divided into 5 groups (A, B, C, D, and E) of the same number and weight and each group was separately penned. Feeding facilitates: Five isocaloric diets, containing graded levels of Cajanus cajan seed (pigeon pea) (0%, 5%, 10%, 15% and 20%) as a replacement of groundnut cake (G.N.C.) were fed. Green fodder (Medicago saliva) was also given at rate of one kg/week/head to avoid vitamin (A) deficiency. Parameters studied were feed intake, feed conversion ratio, live weight gain, live body measurement, and at the end of the experimental Period three kids were randomly selected from each group and transported to the department of meat production University of Khartoum for slaughter to study carcass yield and characteristics, meat chemical composition, meat quality attributes and subjective evaluation of meat quality. The study indicated that final body measurements were not affected by the levels of Cajanus cajan seed. Total live weight gain was 3.543, 6.43, 6.376, 8.543 and 7.210 kg/ head the differences were highly significant (P < 0.01). Hot, cold and half carcass of male goat kids were significantly (P < 0.01). Affected by the level of Cajanus cajan seed. Total body fat increased very highly significantly (P < 0.001) with the increase of Cajanus cajan in the diet. The non-carcass components, were not affected by Cajarrus cajan levels except lung and trachea, four feet, and spleen were significantly affected. Leg, rack, breast plate and shank increased very highly significantly (P < 0.001) by the increase of Cajanus cajan levels. Meat quality attributes were affected by levels of Cajanus cajan. Experiment (2): The study was conducted on l5 male goat kids by selection of three kids from the 5 groups of the first experiment which were raised on 0%, 5%, 10%, 15% and 20% Cajanus cajan seed in the diet as replacement of groundnut cake to study the etfect of different levels on digestibility and faecal analysis. The dry matter intake. faecal output and drymatter digestibility coefficient were not affected by the different levels of Cajanus cajan seed in the diets.Item The Impact of Water Borne Diseases (Malaria & Bilharzia) on Socio — economic development in the gezira scheme sudan(Neelain University, 2008) Mamoun Ahmed Mohamed ElnurABSTRACT This study was carried out in the Gezira scheme to identify the impact of water borne diseases (Malaria & Bilharzia) on rural development in Gezira scheme. The study was established on the assumption that water borne diseases have a drastic effect on the farmer income due to his absence from work because of the above mentioned two diseases. A simple random multistage stratified sample was taken from farmers in the villages of the scheme (l8O) farmers to represent the research community. The study is based on the preliminary information that was gathered by the questionnaire (administered by the researcher himself). The other secondary information was collected fi"om scientific research works, books, Ministry of health documents, internet and the relevant institutions. To identify the impact of these diseases on rural farmer in Gezira scheme, the following variables were used: (a) Variables that concerned the farmer including: (age, level of education, annual income, the extent of his awareness of these diseases and the number of infections he has had and the type of treatment he uses). (b) Variables that concern the region of the farmer consisting of: (health environment, health centers, drinking water and the role of the responsible authorities control and treatment of the diseases). Statistical packages for social sciences (spss) were used to display and interpret the data, chi-square was also used to identify the significant or non-significant relations. The study has established the following results: - these diseases spread in the Gezira region, sometimes culminating to an epidemic level. - Farmers in the Gezira scheme do not get enough health care. - lncome from agricultural production is less than medical treatment expenses for most farmers. The role of the state in the control ofthese diseases in the region is weak. Chi-square has confirmed the following findings: (a) There is significant relation between each ofthe following: Malaria infection and income level. Malaria infection and its affect on agricultural activities of the farmer. - Malaria infection and the disease communicators existent. Malaria infection and the available places oftreatment. Malaria infection and the role of state in control and treatment. The level of income from farming work and the cost of treatment of the diseases. - Bilharzia infection and the farmer used of bonds water. There is also non-significant relation between each of the following: Malaria infection and mortality rate due to its infection. Malaria infection and health care after the year (2000). Bilharzia infection and the available places oftreatment. Bilharzia infection and the level of annual income. Bilharzia infection and the awareness ofthe farmer ofit. Malaria infection and the cost of health services aft (2000). er the year The study has proposed a number of recommendations, the most important of them are: the establishment of cooperative health organi zation for the farmers in each division of the scheme region to work for the control and treatment of these diseases. Also more attention should be given to the social, economic, cultural and manpower development of the farmer of the Gezira scheme, being the real asset of rural development.
