Biological nitrogen fixation (BNF) has a great importance as a non-polluting and a cost-effective way to improve soil fertility through supplying N2 to different agricultural systems. Faba bean (Vicia faba L.) is one of the most efficient nitrogen-fixing legumes that can meet all of their N needs through BNF. Therefore, understanding the impact of rhizobial inoculation and contrasting soil rhizobia on nodulation and N2 fixation in faba bean is crucial to optimize the crop yield, particularly under low fertility soil conditions. The efficiency of Rhizobium leguminosarum in enhancing nitrogen fixation and nutrient uptake in Faba bean and improving soil fertility. the field experiment were carried out at privet farm at tour city South Sinai Governorate, during the two consecutive winter seasons of 2018/2019 and 2019/2020. The experiments were conducted to study the effect of Rhizobium leguminosarum inoculation, organic manure, soil amendment i.e., 0; 25; 30 and 35m3/fed., and four rates of sulfur application i.e., 0; 100; 150 and 200 kg/fed., on growth, productivity, nodulation, soil microbial counts, enzymatic activities, soil total N, P, K, Fe, Zn and Mn, soil chemical properties (pH and EC) and Nitrogen balance of broad bean, Aspany F1 cv. grown under sandy soil conditions. Results revealed that organic manure at the rate of 30m3/fed which is superior significantly plant yield and total yield (ton/fed) followed by organic manure at the rate of 35m3/fed. No significant differences occurred between these two organic treatments in both seasons. Sulfur amendment at the rate of 200 kg/fed followed by the rate of 150 kg/fed had the highest values and significant increases on plant weight; number of branches/plant; plant yield; total yield (ton/fed), there are no significant differences between both treatments in both growing seasons. While, each of the study factors had an individual significant effect on total microbial counts, enzymatic activities (Dehydrogenase and Nitrogenase), nodule No., nodule N%, nodule dry weigh, soil total nitrogen, phosphorus, potassium, Fe, Zn and Mn, soil chemical properties (pH and EC) and Nitrogen balance. But combined treatment organic manure 35m3/fed + sulfur at the rate of 200 kg/fed with rhizobial inoculation gave highest values on all most traits in both seasons.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"51 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125705949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This high amount will increase the risk of hypertension and cardiovascular diseases. In this study, an attempt was done to replace Sodium chloride (NaCl) by salt replacer which is potassium chloride (KCl) in Armenian cucumber pickles. Nine treatments were done with different salts percentages with and without chili pepper and garlic. All treatments were incubated at room temperature for 4 weeks then pH measurement, sensory analysis, and microbial analysis were performed. The pH values decreased with incubation and the lowest pH was 3.53±0.03 for Treatment 4 (75% KCl, 25%NaCl). Treatment 4 showed the highest reduction in both total plate count and yeast count with 78.5±3.0×10 CFU/ml and 73.0±3.0×10 CFU/ml respectively. There were virtually undetectable changes in taste up to 70% KCl (Treatment 6) substitution compared to Treatment 1(100% NaCl) based on the triangle test results. Based on 5-point hedonic scale, the lowest scores for taste were for Treatment 5 (100% KCl) with 2.70±0.40 but they were higher in the samples that contain chili pepper, while the other treatments showed insignificant differences compared to Treatment 1.The different treatments did not show any significant changes with respect to texture based on 5-point hedonic scale except the samples that contain both garlic and chili pepper which showed the lowest scores for taste and texture.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132442290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children with S-ECC often suffer from pain, dietary changes, sleep disorders and behavioral changes. Methods: 1000 Egyptian children aged 3-6 years, including 100 children having complete blood count records participated in this case control study. Children were selected as 500 caries free and 500 with severe early childhood caries. Height and weight were measured for each child. Children who had CBC analysis for medical reason, Hb level was recorded. Results: there was insignificant difference between caries free and S-ECC groups regarding all BMI categories (P > 0.05). Children with low Hb levels (anemic) were significantly higher in S-ECC group than their caries free peers (P < 0.05). Conclusions: there was insignificant correlation between caries distribution and BMI, although there was a negative correlation between caries status and Hb level, indicating that S- ECC has a negative effect on child general health.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134062730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data of this study was mainly collected from the Report on Bangladesh Sample Vital Statistics (SVRS) of different years published by Bangladesh Bureau of Statistics (BBS). It is found that, despite government initiatives to reduce rural-urban disparity in the context of development, the inequality between rural and urban areas persists and challenges continue to evolve. The results of this study should contribute to the creation of innovative and effective policies and programmes that can improve the status of rural-urban differentials in Bangladesh. Findings of this study need to be scientifically utilised in developing suitable programmes addressing the causes of rural-urban differentials in Bangladesh.

As an attempt for water conservation in watermelon cultivation and maximization the irrigation water use efficiency by improving the old unused method of watermelon production in Egypt in addition to, using watermelon grafting on some tolerant rootstocks to water stress. This experiment consisted of 15 treatments (3 cultivation approach of watermelon (rainfed (traditional trenches without irrigation), beds (rows) with drip irrigation according calculated irrigation requirement by CLIMWAT 2.0 and CROPWAT 8.0 software (2320.7m) and renovated method (Trenches with drip by 40% from calculated irrigated requirements (928.28m) × 5 grafting treatments (4 rootstocks bottle gourd and Emphasis hybrid F1 (Lagenaria siceraria), Shintosa F1 hybrid and Ferro RZ F1 hybrid (Cucurbita maxima × C. moschata) and Aswan F1without grafting). The experiment layout was a factorial in strip plot with randomized complete blocks design with three replicates. Planting methods were set in the main strip plot whereas the grafting treatments were set randomly in sub plot. This study was succeeded in producing high yield quantities of watermelon under the conditions of water regime (40%) that were almost equal with the yield under the complete water supply requirements conditions (100%). This result was evidently from the absence of significant differences between the average yield of the two methods, which was significantly higher than the average yield of the traditional trenching method (without irrigation). The renovated trenches improved the quality characteristics of watermelon fruits compared with the traditional trench yield. Grafting on different rootstocks improved all vegetative growth traits and led to an enhancement in the yield components, this was obviously in the significant increase in the vegetative growth values, which reflected by dependency on the yield quantity and quality. The use of both trenches method equipped with the drip irrigation system with grafting on tolerant rootstocks to water shortage led to an increase in the irrigation water use efficiency (IWUS), as it led to doubling the values of (IWUS) compared to the beds with drip irrigation according the calculated water requirements by this Software. In Conclusion, to get the highest yield and quality with maximizing of the (IWUE) on watermelon, it could be recommended to use the renovated trench method equipped with drip irrigation system plus grafting on tolerant rootstocks.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133847038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
