This investigation was carried out during two successive summer seasons of 2015 and 2016 in a private farm at Al-Harsha, Zawia region, Libya, to examine the effect of N-Fertilization (in the form of ammonium sulphate, 20.5% N"; 0, 50 and 100kg/ha")and foliar application with dry yeast extracts (0.2 and 4 g/l) , and its combined effect on growth, yield and its attributes, as well as, quality traits of snap bean (bronco cultivar). The experiment was laid out as spilt plot arrangement in randomized complete blocks design (RCBD) with three replications. The results showed that applying N-Fertilizer and foliar application with dry yeast extract gave significant differences in all studied traits compared to the control (untreated) in favor of 100kg/ha, N and 4g/l dry yeast extract in both seasons. Concerning the combined effect between N-Fertilization and dry yeast extract, there were significant effects in most of studied traits in both seasons. The combination of 100kg N/ha, and 4 g/l dry yeast extract recorded the highest mean values of vegetative growth characters yield components, total yield and pod quality in the both seasons. Conclusively: it could be concluded that the treatment of NFertilization in the form of ammonium sulphate (20.5% N) at 100 kg N/ha and foliar application with dry yeast extract at the level of 4 g/l, as well as, the combined effect between 100 kg N/ha and 4 g/l dry yeast extract enhancing the studied characters of snap bean.
该调查于2015年和2016年连续两个夏季在利比亚扎维亚地区Al-Harsha的一个私人农场进行，以检查N-施肥(以硫酸铵的形式，20.5% N”;0、50和100kg/ha”)和叶面施用干酵母浸出物(0.2和4 g/l)，研究其对豇豆生长、产量及其性状和品质性状的综合影响。试验采用随机完全区设计(RCBD)，分区布置，3个重复。结果表明:与对照(未处理)相比，施用氮肥和叶面施用干酵母浸出物在两个季节的所有研究性状均显著差异于施用100kg/ha、氮肥和4g/l干酵母浸出物。氮肥与干酵母浸膏的联合效应在两个季节对大部分性状均有显著影响。100kg N/ha和4 g/l干酵母浸膏的组合在两个季节的营养生长性状、产量组成、总产量和荚果品质平均值最高。综上所述，100 kg N/ha硫酸铵(20.5% N)和4 g/l干酵母浸膏叶面施氮处理以及100 kg N/ha和4 g/l干酵母浸膏的联合作用均能提高豆荚的各项性状。

Research problem is The development of Egyptian exports comes at the forefront of the priorities of Egyptian decision-makers in general and the development of agricultural exports in particular, which faces many problems and obstacles that stand in the way of increasing its export capacity, some of which are related to competitiveness in foreign markets, capacity and export prices, and our Egyptian exports of frozen vegetables, juices and syrups are affected with that. The results of the research revealed that to show the impact of policies on the exports and imports of frozen vegetables, juices and sherbets for the two periods (1990-2004) (2005-2020) that there is a real effect for the two periods on the exported quantity of frozen vegetables, juices and syrups, their value and the value of the trade balance for them. The statistical significance of the quantity of imports was not confirmed. And its value for frozen vegetables, juices and syrups, where the calculated (F) was less than the tabular value. Using dummy variables, the statistically significant increase was confirmed for the two periods, as the value of the increase in the Egyptian trade balance amounted to about 4.2%, 6.2% of their average value of the trade balance of Egyptian frozen vegetables by about 14.2, 60.1 thousand dollars, respectively, while the increase in the trade balance for juices and drinks for the two periods amounted to 6.3%, 8.3% From the average of the two periods of about 4.3, 53.9 thousand dollars. The research recommends that increasing production and thus increasing Egyptian exports of frozen vegetables, juices and sherbet is the only way to improve the Egyptian agricultural trade balance for the two commodities, and that this is the only way to increase all manufactured agricultural products that increase the added value of these products.

A field experiment was carried out at Mallawi Agriculture Research Station, Minia Governorate, Egypt, during the two successive seasons (2018/2019 and 2019/2020). 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.

The present investigation aimed to study the impact of water stress on three quinoa cultivars namely; quinoa 1, rainbow and American cultivar. Where, the three quinoa cultivars rated as various reactions for water deficit tolerance and were evaluated under the control and water stress conditions during two growing seasons. Some agro-morphological and physiological traits associated with water stress tolerance were measured under both conditions during the two seasons. Also, heritability in broad sense, PCV %, GCV %, D Z , GA and GAM % were the most important genetic parameters calculated for all studied traits under the same conditions during the two growing seasons. Water deficit tolerance indices were a fruitful and fertile test used to determine the various tolerance degrees of drought stress in the three quinoa cultivars for the traits; number of branches/plant, number of leaves/plant, 1000-seeds weight and seed yield/plant in both years. Five polymorphic protein bands out of six produced (83.3%) of polymorphism which indicated the genetic variations of three quinoa cultivars under water stress. The three quinoa cultivars were able to prove that they are varied tolerant to water stress, depending on the results of all studied traits, especially yield and its components, root and physiological traits namely; proline, glycine betaine and trehalose contents. Where, the cultivar quinoa 1 was coming at the first place as a tolerant, followed by rainbow and then followed by the American cultivar as a moderate to sensitive. In any case, the three quinoa cultivars recorded a good and satisfactory yield under water stress conditions compared to the standard experiment in parallel of the results of roots and physiological attributes represented in proline, glycine betaine and trehalose contents production which were excellent under stress compared to the control conditions. Using SCoT primers, there were high genetic diversity and generated 131 fragments where 89 of them were monomorphic besides, 42 polymorphic bands with 32.06 % polymorphism. In addition, detected 42 specific markers (17 positive and 25 negative) as genetic markers used at the molecular level to identify quinoa cultivars that are tolerant to water stress over those that are moderately to sensitive. Changes in isoenzymic were studied using PAGE under nonreduced, non-denatured conditions at 4 _C. Native PAGE analysis was performed for various enzymes involved in the ascorbate–glutathione cycle on a gel (10%) with protein load of 50 lg in each well. Specific procedures for running and staining of gels for different enzymes are given below. Staining of gels SOD activity. Gels were soaked NBT solution potassium

Due to the limited water resources in Egypt and its occurrence in the driest areas in the world, in addition to climatic changes and rising temperatures, which negatively affect the increase in water needs required to irrigate crops, it was necessary for us to think about applying the most sustainable technologies available, which will face all these challenges in an environmentally friendly manner. 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.

EgelaM.","doi":"10.36632/mejar/2022.11.2.29","DOIUrl":"https://doi.org/10.36632/mejar/2022.11.2.29","url":null,"abstract":"Due to the limited water resources in Egypt and its occurrence in the driest areas in the world, in addition to climatic changes and rising temperatures, which negatively affect the increase in water needs required to irrigate crops, it was necessary for us to think about applying the most sustainable technologies available, which will face all these challenges in an environmentally friendly manner. 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}
