The experiments were allocated in a spilt plot design with three replicates. The main plots assigned to four biofertilization treatments i.e. control, Azospirllium ssp, Pseudomonas ssp and mixture of Azospirllium ssp and Pseudomonas ssp). The sub plots were devoted for three levels of nitrogen and phosphorus fertilizers (50, 75, and 100% of RD \"(90 kg N) and 31 kg P2O5 (15.5%)\". Sugar beet plant growth, microbial densities in the rhizosphere, root yield, Physical and chemical properties of sugar beet roots and recoverable sugar yield (tonfed) were studied. Generally application of the above mentioned fertilizers individually or interaction resulted in a significant effect on all the studied traits in both seasons as compared with the control. On one hand the biofertilizer consisted of a mixture of Azospirllium ssp and Pseudomonas ssp recorded the highest values of microbial densities in the rhizosphere, plant growth parameters root yield, recoverable sugar yield (ton/fed), physical and chemical properties of roots and obtained sugar compare with other treatments?. On the other hand, treatment of 100% of nitrogen and phosphorus fertilizers gave the highest values of all the studied characters. The interactions between biofertilizers, nitrogen and phosphorus fertilizers significantly affected the studied traits in both seasons. Under the conditions of present work, the results suggest that sugar beet inoculated with a mixture of Azospirllium ssp, Pseudomonas ssp combined with 75 % RD of nitrogen and phosphorus fertilizers (204.5 &150 kg/fed) is highly recommended to obtain the highest yield of sugar beet.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"25 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":"115597015","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}

Besides, the study dealt with the importance of human resource development, as well as the difficulties encountered in resource development, and the challenges facing human development, especially in developing countries.

One of the most sustainable, cheap and available techniques is the recycling of organic agricultural waste, from which organic fertilizers can be produced and also can be used as organic mulching as a sustainable alternative to plastic mulching. Soil moisture content (SMC),Water application efficiency (WAE), soil organic matter content (SOMC), and activity of microorganisms (AM), soil electrical conductivity (SEC), yield (Y Tomato ) and water productivity of tomato (WP Tomato ) are investigated with organic mulching and integrated N-fertilization treatments under dry Egyptian conditions and also, the previous evaluation criteria were modeled using the SALTMED simulation model. The results indicated that, using of organic mulching also led to a decrease in the evaporation rate thus, the soil surface remains moist for as long as possible, and the accumulation of salts in sandy soils decreases which mean, protecting the soil surface and the root zone from increasing water and salt stress. The results also showed the importance of the integrated nitrogen fertilization, which increases the proportion of adding the organic component. Using of organic mulching and integrated nitrogen fertilization led to an increase in the SMC, WAE, SOMC and an increase in biological activity, as well as a decrease in the accumulation of salts in the soil. It combines with the application of these techniques all the encouraging benefits of sustaining, increasing and improving the productivity of tomatoes and any other crop in dry sandy soils with limited irrigation water and drought. The study concluded that relying on organic mulching and integrated nitrogen fertilization increased the productivity and water productivity of tomatoes, where the highest values were when using organic mulching and adding 50% of organic nitrogen + 50% of mineral nitrogen fertilizers. The results also showed the accuracy of the SALTMED simulation model in simulating the evaluation criteria that were studied using drip irrigation system under sandy soils in Egypt.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"35 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":"123507431","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}
