Saline soil is one of the major abiotic stresses that minify plant growth and crop productivity in arid and semiarid regions. 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.
盐碱地是干旱和半干旱地区影响植物生长和作物生产力的主要非生物胁迫之一。2019年夏季，通过盆栽试验，研究了沸石和尿素肥对盐碱条件下玉米生长和产量的影响。试验设计为析因RCBD，共设4个重复，第一因子为沸石水平{0(对照)、2、4和6%}，第二因子为尿素水平{0(对照)、30、60和90 kg N/料}。结果表明，与对照(0%沸石)相比，施用沸石处理显著提高了玉米的营养生长特征，即株高、鲜重和干重、总叶绿素(SPAD)和叶面积。在所研究的沸石浓度中，6%沸石处理的营养生长参数最高。氮素/投喂量为90 kg的尿素处理的营养生长指标最高，而未处理(对照)的营养生长指标最低。与未处理的土壤相比，施用沸石也提高了植株氮磷钾含量和土壤有效氮磷钾含量。在6%沸石率下，植株氮磷钾含量和土壤有效氮磷钾含量最高。同样，与对照相比，施用90 kg N/ d尿素肥的植株氮磷钾含量和土壤有效氮磷钾含量最高。结果表明，沸石改性可以缓解盐胁迫，促进植物生长，增强植物对养分的吸收和土壤中养分的保留。结果表明，沸石改性是提高干旱半干旱区低质量土壤的作物生产力和粮食产量，减少养分损失和环境污染，扩大农业利用的有效工具。

Two field experiments were conducted during two winter successive seasons 2019/2020 and 2020/2021 at the National Research Station, Area, Egypt. The purpose of the study was to investigate the link between vegetative development, yield, yield components, and numerous metabolic variables components of the "Giza 716" Egyptian faba bean cultivar (Vicia faba L.) to foliar application of three growth regulators; paclobutrazol (PBZ; 30, 60 and 90 ppm), mepiquat chloride (MC; 500, 1000 and 1500 ppm) and baritone (AGR; 400, 600 and 800 ppm). 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. Data also show the most effectiveness treatments were AGR at 400 and 600 ppm followed by PBZ at 30 ppm for all growth parameters. Foliar application of PBZ up to 60 ppm, significantly increased the area of fourth leaf (4 th LA), leaf area index (LAI), specific leaf weight (SLW), crop growth rate (CGR), net assimilation rate (NAR), and relative growth rate (RGR) compared with relevant untreated control units. compared control plants.

Chloride occurs predominantly as Cl in soil, plant, and considering as a micronutrient largely excluded by plants due to its ubiquity and abundance in nature. 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.

氯化物主要以Cl的形式存在于土壤和植物中，由于其在自然界中的普遍存在和丰富，被认为是一种被植物排除在外的微量营养素。它是高等植物必需的微量营养素，参与多种生理代谢过程。包括渗透和气孔调节，光合作用中氧的进化，抗病性和耐受性。氯化物(Cl)一直被认为对农业有害，因为它在盐碱地中的毒性作用及其与硝酸盐(NO3)的拮抗相互作用，从而损害NO3的营养。人们普遍认为，Cl会抑制高等植物对NO3的吸收和积累，从而降低作物产量。然而，我们最近发现Cl具有新的有益的常量营养素功能，可以改善植物生长、组织水平衡、植物水分关系、光合性能和水分利用效率(WUE)。增加植物生物量表明Cl也可能提高氮素利用效率(NUE)。钠离子和钾离子周围水的结构是检验相互作用电位质量的关键，它们并没有完全对准它们的电场，而是倾斜的。这种倾斜对钾的影响比对钠的影响更明显。钠的水合数量限制在5个或6个分子，而钾的水合数量则在5到10个分子之间。Na和K之间最显著的能量差异存在于第一壳层。在此条件下，水分子之间的相互作用非常强，Na对土壤盐分的影响大于K。但在盐胁迫下，Na含量的增加往往伴随着Cl的积累和K的损失。由于氮素有效性是陆地植物生长的瓶颈，农业中频繁使用的过量NO3施肥成为世界范围内的一个主要环境问题，导致作物特别是蔬菜叶片NO3过量积累，对人体健康构成潜在风险。旨在通过减少NO3施肥来提高植物氮素利用效率(NUE)的新耕作方法将促进更健康和更可持续的农业。考虑到植物体内Cl和NO3的强相互作用，我们已经验证了Cl是否确实影响植物体内NO3的积累和NUE。据我们所知，我们首次提供了一个直接的证明，表明Cl与损害NO3营养相反，促进了植物对NO3的利用，提高了NUE。这主要是由于Cl -提高了N - NO3利用效率(NUTE)，而当NO3作为唯一N源时，Cl -对N - no -吸收效率(NUPE)的影响很小或中等。在种内和种间水平上，叶片Cl含量与NUE / NUTE或植物生长之间存在明显的正相关关系。优化NO3与Cl的比例是提高作物产量和质量、农业用地可持续性以及减少NO3对环境和人类健康的负面生态影响的有用工具。

Surface geophysical survey was performed along Qift EL-Quseir Road between the Red Sea coast at the east and Qift town at the River Nile westward, Central Eastern Desert, Egypt, to delineate its groundwater situation. 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. Some exploratory drilling wells can be recommended in downstream portions of W.Kareem, El Beida area, W.Hamad and El Sheikh Abd Al'al region.
