A pot experiment was conducted during the summer season of 2019 to evaluate the effect of zeolite and urea fertilizer on growth and yield of maize grown under saline conditions. The experiment design was Factorial RCBD with four replicates, the first factor was zeolite level {0 (control), 2, 4 and 6 %} and the second factor was urea fertilizer level {0 (control), 30, 60 and 90 kg N/fed}. Results showed a significant increase in the vegetative growth characteristics of maize i.e. plant height, fresh and dry weight, total chlorophyll (SPAD), and leaf area under zeolite application treatments as compared with control (0% zeolite). Among the studied zeolite rates, 6% zeolite treatment resulted the highest vegetative growth parameters. Moreover, the application of urea fertilizer at 90 kg N/fed recorded the highest values of vegetative growth parameters, as compared with untreated treatment (control) which gave the lowest values of these traits. Zeolite application also enhanced plant NPK content and soil available NPK as compared with the untreated soil. The highest plant NPK content and soil available NPK were recorded under 6% zeolite rate. Similarly, application of 90 kg N/fed of urea fertilizer produced the highest plant NPK content and soil available NPK as compared with control. These results revealed that zeolite amendment mitigated salt stress, improved plant growth, and enhanced absorbing nutrients by plant and retaining nutrients in soil. The results concluded that zeolite amendment can be an efficient tool to increase crop productivity and food production, reduce nutrient losses and environmental pollution, and to expand the agricultural utilization of the low-quality soil in arid and semi-arid regions.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"1 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":"130103250","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 foliar application of PBZ, MC, and AGR had positive effects on all growth and yield parameters. On the other hand, the three growth regulators reduced plant height, fresh and dry weights of branches and leaves/plant, fourth leaf area and leaf area index, specific leaf weight, crop growth rate, net assimilation rate, relative growth rate, and yield (number of pods per plant, number of seeds per pod, pod weight/plant, seed and straw yield/plant, seed and straw yield/feddan, seed index), and harvest index), when used in high concentrations. By boosting total carbs, crude protein, total free amino acids, nitrogen, phosphate, and potassium, PBZ, MC, and AGR considerably boosted total photosynthetic pigments content in leaves and improved seed quality and nutritional value. Generally, foliar application of PBZ, MC, and AGR When used at low quantities, it had a favorable impact on growth parameters, photosynthetic pigments, seed yield and yield components, as well as several biochemical components of the faba bean seeds yield. net assimilation rate (NAR), and relative growth rate (RGR), as compared with untreated control plants, highly significant.

It is an essential micronutrient of higher plants and participates in several physiological metabolism processes. Including osmotic and stomatal regulation, evolution of oxygen in photosynthesis, disease resistance and tolerance. Chloride (Cl) has traditionally been considered harmful to agriculture because of its toxic effects in saline soils and its antagonistic interaction with nitrate (NO3), which impairs NO3 nutrition. It has been largely believed that Cl antagonizes NO3 uptake and accumulation in higher plants, reducing crop yield. However, we have recently uncovered that Cl has new beneficial macronutrient functions that improve plant growth, tissue water balance, plant water relations, photosynthetic performance, and water-use efficiency (WUE). Increasing plant biomass indicates in turn that Cl may also improve nitrogen use efficiency (NUE). Structure of water around the sodium and potassium ions is a key test of the quality of interaction potentials, and are not completely aligned toward their electric fields, but rather tilted. This tilt is more defined for potassium than it is for sodium. The hydration number of sodium is restricted to either five or sex molecules, however for potassium has ranging from five to ten molecules. Most striking energetic difference between Na and K resides in the first shell. Water molecules have a very strong interact under such condition Na is more effect on the soil salinity than K. However, an increase in Na content is always accompanied by Cl accumulation and K loss in plants exposed to salt (NaCl) stress.Considering that N availability is a bottleneck for the growth of land plants excessive NO3 fertilization frequently used in agriculture becomes a major environmental concern worldwide, causing excessive accumulation leaf NO3 in crops particularly in vegetables, that poses a potential risk to human health. New farming practices aimed to enhance plant nitrogen use efficiency (NUE), by reducing NO3 fertilization should promote a healthier and more sustainable agriculture. Given the strong interaction between Cl and NO3 homeostasis in plants, we have verified if indeed Cl affects NO3 accumulation and NUE in plants. For the first time to our knowledge, we provide a direct demonstration, which shows that Cl, contrary to impairing NO3 nutrition, facilitates NO3 utilization and improves NUE in plants. This is largely due to Cl− improvement of the N–NO3 utilization efficiency (NUTE), having little or moderate effect on N–NO − uptake efficiency (NUPE) when NO3 is used as the sole N source. Clear positive correlations between leaf Cl content vs. NUE / NUTE or plant growth have been established at both intraand interspecies levels. Optimal NO3 versus Cl ratios become a useful tool for increasing crop yield and quality, sustainability of agricultural land a","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"14 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":"126847697","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 groundwater in this hyper-arid area has a precious value for the different development objectives. The study area is characterized by presence of several aquifers (fracture basement, Nakheil formation, Nubian sandstone and Quaternary aquifers). These aquifers represent the main source of groundwater that used in tourist activities, mining and agriculture projects. The integration between surface geophysical techniques (land magnetic profiles, vertical electrical soundings (VES's) and electric resistance tomography), cover all gaps in study area. These surveys determine the horizontal and vertical extensions of the lithological succession, estimate the aquifers dimensions, the depth to water, the water level, estimate the characteristics of the water bearing formations, detect the basement relief, geological structures that affect the groundwater occurrences, locate the best sites for drilling productive water wells and finally Assess the groundwater potentialities in the study area. From this geophysical study, it can be mentioned that the promising sites for digging new productive water wells are, the delta of Fawakheir–Mathula basin, the Nubian sandstone plateau area (between km 15 to km 65 East the Nile), localities of El Sid and the downstream portion of W.Um Slimat, location of the delta of Abu Zeran-Ambagi basin (between km 2 to km9 from the Red Sea coast) and the downstream of W.El Nakheil sub-basin.
