So, a research trial was performed during the growing season of 2022/ 2023 for improving the onion growth performance and its quantitative and qualitative yield under deficit irrigation via some soil amendments and some beneficial element spraying. Three irrigation regimes [ I 1 : Four irrigations, I 2 : Three irrigations and I 3 : Two irrigations were evaluated as main plots. The soil amendments [ T 1 : Without soil amendments), T 2 : Biochar, T 3 : Zeolite, T 4 : Compost (plant residues), at rate of 10 Mg ha -1 for each soil amendment] were evaluated as sub main plots. Also, the foliar application of nutrient elements [ F 1 : Without foliar application, F 2 : Boron, F 3 : Copper, F 4 : Selenium, at rate of 10 mg L -1 for each element ) was assessed as sub-main plots. Parameters expressing the growth performance ( e.g., foliage dry weight, chlorophyll, proline and catalase enzyme) at the period of 75 days from transplanting were determined. Also, traits expressing quantitative yield ( e.g., total and marketable bulb yield) and qualitative yield ( e.g., carbohydrate, protein, vitamin C, total dissolved solids and pyruvic acid) were estimated. The findings indicate that the traditional irrigation approach (I 1 ) caused the best performance in terms of both quantitative and qualitative yield. Following this, the water deficit treatments ( I 2 and I 3 ) resulted in lower performance, as the I 3 treatment led to the lowest performance. When considering soil amendments, compost proved to be the most effective, followed by zeolite, then biochar, while, the control treatment ( without soil amendments) was the least effective. Regarding the beneficial elements, the order of effectiveness from most to least was Se > Cu > B > F 1 (control). Generally, the most favorable outcomes were observed when combining compost ( T 4 ) with selenium foliar application ( F 4 ), within the framework of the traditional irrigation treatment ( I 1 ). Notably, the growth performance, as well as the quantitative and qualitative yield, were better when employing the combined approach of compost (T 4 ) and selenium foliar application (F 4 ) under the water deficit treatment (I 2 ) compared to plants grown traditionally without any of the studied substances (I 1 x T 1 x F 1 ). In conclusion, this research underscores the potential of soil amendments, and nutrient application strategies to enhance onion growth and yield under water scarcity. By continuously refining these approaches and embracing a holistic perspective, the agricultural community can move closer to ensuring food security and sustainability in challenging environmental conditions.","PeriodicalId":44612,"journal":{"name":"EGYPTIAN JOURNAL OF SOIL SCIENCE","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141230169","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 aim of this study was to assess and compare various stress tolerance indices in order to identify the most drought-tolerant wheat genotypes for the future wheat breeding programs. For this purpose, 28 bread wheat genotypes (7 parents and their 21 hybrids) were evaluated in two separate experiments under water-deficit (two irrigations) and well-watered (five irrigations). The drought tolerance indices were calculated based on grain yield under normal (Yp) and stress (Ys) conditions. Highly significant differences were detected among the tested genotypes for all the studied traits, under normal and water stress conditions. Water-deficit stress substantially declined the means of all the studied traits. Water stress caused reductions in days to 50 % heading, plant height, spike length, number of kernels / spike, 1000-kernel weight and grain yield / plant traits by 5.19, 11.15, 16.39, 16.90, 10.67 and 8.98 % respectively. Based on tolerance index (TO L) and stress tolerance index (SSI), the two parents Misr 2 and Line 117, as well as, the crosses Sids14 x Sakha 95, Sids14 x Line 117 and Misr 2 x Line 136 were identified as the suitable genotypes under water stress conditions due to lower values of these indices. Moreover, these genotypes expressed the highest yield under stress conditions. Therefore, the parental genotypes Sids 14 and Sakha 95, as well as the hybrids Sakha 95 x Misr 2 and Sakha 95 x line 115, were identified as highly drought-tolerant genotypes.

Hence, the prioritization of crop research is the development of crop types capable of sustaining or enhancing yields while minimizing water usage. Hence, it is imperative to employ a technique aimed at mitigating the plant's water loss by transpiration, with one such approach being the utilization of antitranspirants. The current investigation involved a field in a split split-plot design experiment aimed at comprehending the effects of antitranspirants on the physiological and yield attributes of wheat cultivars ( Triticum aestivum L.) under varying irrigation levels. The present investigation encompassed three different irrigation treatments, namely 100%, 80%, and 60% of the recommended irrigation levels, applied at rates of 5476, 4381, and 3285 m 3 ha -1 , respectively. Additionally, three distinct wheat cultivars, namely Sids 14, Giza 171, and Sakha 95, were included in the study. Furthermore, four treatments consisting of kaolin at a concentration of 5%, potassium sulphate at a concentration of 200 mg L -1 , paraffine at a concentration of 6%, and a control treatment involving water spray were also incorporated. The physiological parameters that were assessed included total chlorophyll, membrane stability index, relative water content, stomatal density, and transpiration intensity. The growth and yield parameters were documented subsequent to the crop's harvest. The findings of the study indicate that exposing wheat cultivars to prescribed irrigation resulted in notable enhancements in the examined feature, as compared to alternative irrigation treatments. The application of antitranspirants resulted in notable enhancements in the observed characteristics across all cultivars when subjected to irrigation intensities of 80% and 100%. Furthermore, the three wheat cultivars exhibited varying responses under the three irrigation regimens, as well as in the presence or absence of foliar spray application of antitranspirants.","PeriodicalId":44612,"journal":{"name":"EGYPTIAN JOURNAL OF SOIL SCIENCE","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140084687","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 study's primary goal was to assess the soil's level of fertility and land suitability for some strategic crops using ASLE software and GIS techniques in some soils at Samanoud District, Gharbia Governorate, Egypt. For this aim, 17 soil samples were randomly distributed over the study area according to locations using GPS. The studied area covers about 166.2 km 2 . In the southern and western regions of the study area, higher clay values were found. The concentrations of N, P and K were evaluated as low or medium based on their availability in the studied area. In the northern regions of the examined area, there was a higher concentration of OM and available P. On the other hand, higher available N levels were seen in the southern regions. Meanwhile, the higher available K values were recorded close to the center of the study region. According to the ASLE program, there are two classes of fertility index data outputs in the area under study: (i) Fair-C3 and (ii) Poor-C4. The soils in the study area were very suitable for growing wheat (S1) and fitted into two classes: very suitable (S1) and suitable (S2) for maize cultivation. In addition, the studied area fitted into three classes including very suitable classes (S1), suitable (S2), and currently unsuitable (N1) for faba bean cultivation. However, the studied area was classified into moderately suitable (S3) and marginally suitable (S4) for rice cultivation. In essence, the appropriate field crops could be categorized according to its suitability as follows: wheat, maize, faba beans, and rice.

The data was recorded after 80 - 140 days from planting, where polynomial regression analysis was estimated between the growth stages and growth parameters. Similarly, 100% of the WR considerably increases plant height, leaf number, leaf fresh weight, and growth attributes like absolute growth rate, specific leaf area, leaf area index, chlorophyll a, b, and total carotenoids contents. While the irrigation at a rate of 60% WR led to an intrinsic rise in leaf water saturation deficit, proline content, and ascorbic acid content. Bulb parameters such as weight, diameter, and number of cloves per bulb, besides yield quantity with bulb grade one G1 (above 5.5 cm), pyruvic acid as pungency, and dry matter contents were determined to be at their highest values with irrigation at 100% of the WR. A 60% of the WR water shortage represented the high yield reduction with grade 4 (less than 3.5 cm). Pearson's correlation revealed positive relationships between bulb yield, characteristics, and growth attributes.

This review investigates how drought stress impacts plants and how management practices can be utilized to reduce the negative effects. Special attention is given to nano-farming where application of nanomaterials may ameliorate drought stress by increasing enzymatic antioxidants and decreasing generation of reactive oxygen species (ROS). Despite the promising results of nano-farming we conclude that further research is required, particularly to investigate potential negative effects, for example on nano-toxicity where particles can enter groundwater or into the food chain.

The Ca silicate was prepared using a green synthesis technique and subsequently activated by different acids, such as HNO 3 and H 3 PO 4 , producing Ca silicate-NO 3 NPs and Ca silicate-PO 4 NPs, respectively. The characterization of the prepared samples was conducted by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and dynamic light scattering (DLS). The removal of Na + and BO 3−3 from solutions was examined by activated calcium silicate NPs, considering different factors such as Na + and BO 3−3 concentrations, adsorption time, solution pH, and temperature. The results highlighted that the maximum removal of Na + (18.78%) was achieved by using Ca silicate NPs at an equilibrium contact time of 6 h, a concentration of 20 ppm, a pH of 8.1, and a temperature of 298 K. For BO 3−3 , the maximum removal of (22.47%) was observed at an equilibrium contact time of 6 hours, a concentration of 54.54 ppm, a pH of 6.08, and a temperature of 308.5 K. Freundlich and Langmuir isotherm models were utilized to analyze the experimental data. According to the findings, the Langmuir isotherm model more accurately characterized the experimental data. The adsorption kinetics were studied using the pseudo-first-order and pseudo-second-order models, revealing that the pseudo-second-order model best explained the adsorption kinetics. Furthermore, the study assessed the application of three levels (0, 4, and 8 g pot -1 ) of Ca silicate NPs, Ca silicate-NO 3 NPs, and Ca silicate-PO 4 NPs to the dill plants ( Anethum graveolens L.). Evaluation parameters include fresh and dry weight, Na, B, Ca, and Si concentrations, and plant tissue trace elements.
