This study aimed to molecularly characterize diosgenin biosynthesis in various organs of fenugreek, including flowers, immature leaves, developing leaves, mature leaves, stems, roots, and pods. The biosynthetic pathway involves vital enzymes such as squalene synthase, squalene monooxygenase, cycloartenol synthase, and Sterol-3-ß-glucosyl transferase. The study found that flowers and roots exhibited the highest gene expression levels, indicating their potential significance in diosgenin biosynthesis. Diosgenin content was quantified using high-performance liquid chromatography, with seeds being the primary source. The findings suggest that fenugreek offers a cost-effective and rapid alternative to yam for diosgenin production, and the differential accumulation of diosgenin in different plant organs underscores the importance of understanding organ-specific biosynthesis. This comprehensive analysis provides valuable insights into fenugreek’s potential as a bioresource for diosgenin and its diverse applications in medicine and agriculture.","PeriodicalId":36570,"journal":{"name":"Journal of Aridland Agriculture","volume":"27 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140427183","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 process of Clevenger-type water distillation was employed to extract essential oils from two distinct plant species. Subsequently, the insecticidal properties of these oils were evaluated against specimens of the American wheat weevil (Rhyzopertha dominica) and the red flour beetle (Tribolium castaneum), belonging to the Coleoptera: Bostrichidae and Tenebrionidae families, respectively. Eucalyptus oil exhibited the highest level of inhibition of insects’ reproduction. Still, when tested on adults of both types of insects, eucalyptus and spearmint oils were more effective than the control treatment. A complete inhibition of egg-laying activity (100%) was achieved using a 7% concentration of eucalyptus oil. The trials were done within controlled laboratory settings, with a notable absence of tests conducted under authentic operational conditions. Researchers who want to learn more about using essential oils as insecticides in the future should focus on making pesticide formulations that work well in a wide range of production settings.","PeriodicalId":36570,"journal":{"name":"Journal of Aridland Agriculture","volume":"111 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139174920","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}

In this work, we looked into how different phenylpropanoid chemicals accumulated in Euonymus alatus following exposure to different concentrations of CuCl2 (0.1, 0.5, and 1 mM), HgCl2 (0.1, 0.5, and 1 mM), and NiSO4 (10, 50, and 100 mM). We analyzed some of the individual phenolic chemicals by high-performance liquid chromatography (HPLC). In nearly all cases, rutin showed the largest concentration among the phenylpropanoid chemicals, followed by epicatechin, sinapic acid, p-coumaric acid, trans-cinnamic acid, ferulic acid, and caffeic acid. However, due to the change in the concentration of the heavy metals, the amount of phenylpropanoid changed. The highest accumulation of phenylpropanoid was documented in 0.1 mM CuCl2, whereas it was reduced in 1 mM HgCl2 exposed plants. These findings unequivocally demonstrate that the phenylpropanoid metabolic pathway took part in the heavy metal tolerance process, which shielded E. alatus from the oxidative damage brought on by heavy metals. Thus, under a variety of environmental stress situations, this species with a high tolerance to heavy metals may survive.","PeriodicalId":36570,"journal":{"name":"Journal of Aridland Agriculture","volume":"388 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010972","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}

However, a comprehensive understanding of the influence of soil texture and climate conditions on SOC sequestration under CA remains limited. To address this knowledge gap, we conducted a systematic review using the PRISMA method, analyzing data from 35 peer-reviewed articles encompassing 71 field experiments and 451 observations worldwide. Our findings demonstrate the substantial positive impact of CA on SOC sequestration, with an overall increase of approximately 78%. Remarkably, only a mere 2% of observations reported neutral effects, while 20% indicated adverse outcomes. Notably, SOC sequestration rates were highest in tropical regions experiencing dry winters, reaching an impressive 2.50 Mg/ha/year in the topsoil layers. Moreover, fine and moderate textured soils, such as clay, clay loam, loam, and clay sandy, exhibited higher SOC sequestration rates (20-27%) compared to coarse-textured soils dominated by sandy proportions (9%). These findings emphasize the significance of climate conditions and soil texture in shaping the impact of CA on SOC sequestration.","PeriodicalId":36570,"journal":{"name":"Journal of Aridland Agriculture","volume":"365 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011014","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 experiment was set up using a randomized complete block design with three replications, Soybean varieties showed variability in terms of plant stature, number of branches plant-1 and number of nodules plant-1. Application of 100% of RD of phosphorus gave maximum plant height, number of branches plant-1 and nodules plant-1 at 45, 60 and 75 DATs. In the case of variety, Binasoybean-1 showed the maximum number of pods plant-1, 100-seed weight, and seed yield. Application of 100% RD of phosphorus exhibited maximum number of branches plant-1, pod length, pods plant-1, seeds pod-1, seed yield, protein and oil contents. Considering the interaction effect, Binasoybean-1 responded well to the application of 100% of RD of phosphorus and gave the maximum seed yield with the highest protein content.

Studying the response of soil properties to the applied soil amendments represents one of the critical parameters in agricultural field management for improving crop production and water use efficiency of Iraqi strategic crops. The effect of soil amendments (compost = 7.5 t/ha and perlite/0.1% Polyvinyl alcohol = 0.25 t/ha) on the water use efficiency and crop production under three levels of water depletion (30, 50, and 70%) of the available soil water was examined for wheat and barley crops. The study was applied under the sprinkler irrigation system. The experimental design was RCBD within 6 treatments and 3 replications for each wheat and barley. The results show that the soil amendments of expanded perlite and compost exhibit an improvement in the soil properties of soil bulk density and soil water content. Soil amendments, especially, the expanded perlite improved the crop yield and water use efficiency under all irrigation levels. The effect of expanded perlite shows the maximum effect on barley production under the 50% irrigation level with 3500 kg/ha. The irrigation level of 70% could be a worth-able management strategy if it is associated with the soil amendments of compost and expanded perlite. As a result, the effectiveness of expanded perlite increased with the increase in the drought of Iraqi soil.","PeriodicalId":36570,"journal":{"name":"Journal of Aridland Agriculture","volume":"46 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139261713","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}

It deals with the difficulty of incorrectly identifying crops with comparable phenology patterns, a problem that frequently arises in agricultural remote sensing. Two datasets from Nanajangudu taluk in the Mysore district, which has a widely varied irrigated agriculture system, are used to assess the model. Using self-supervised learning, the 2S-DT model addresses the misclassification issue that frequently occurs when working with unlabeled classes, especially in high-resolution images. It uses class decomposition (CD) layer and a downstream learning approach. Using the model’s learning and the particulars of each geographical context, this layer improves the information’s arrangement. Our model architecture’s foundation is ResNet, a well-known deep learning framework. Each residual block in our ResNet architecture is made up of two 3x3 convolutional layers. Each convolutional layer is followed by batch normalization and Rectified Linear Unit (ReLU) activation functions, which improve the model’s capacity for learning. We utilized a 7x7 convolutional layer with 64 filters and a stride of 2 for Conv1 in ResNet18, resulting in an output size of 112x112x64. Conv2, which consists of Res2a and Res2b, generated an output with the dimensions 48x48x64. Conv3, which included Res3a and Res3b, produced an output with the dimensions 28x28x128. These architectural selections were made with our experimental needs in mind. The 2S-DT model’s newly added features make it easier to identify classes and update weights, improving the stability of the features’ spatial and spectral data. Extensive tests performed on two datasets show the model’s viability. Overall accuracy has improved significantly, with the 2S-DT model surpassing comparable models like TVSM, 3DCAE, and GAN Model by obtaining 95.65% accuracy for dataset 1 and 88.91% accuracy for dataset 2.","PeriodicalId":36570,"journal":{"name":"Journal of Aridland Agriculture","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136077976","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}
