Thus, there is an urgent need for environmentally friendly techniques to enhance growth and productivity of wheat ( Triticum aestivum L.) growing in saltine soils. In our 2-year field experiments, we evaluated the effect of two beneficial plant growth-promoting rhizobacteria (PGPR; Azospirillum brasilense and Bacillus circulans ) and the foliar application of potassium silicate (K 2 SiO 3 ; PS) to improve growth and yield of three cultivars of wheat, namely Misr 1, Gemmeza 12 and Sakha 95, under salt-affected soils (EC=7.71). The results supported our hypothesis that the combined application of PGPR+PS significantly ( P <0.05) improved growth and yield, nutrients (N, Na + and K + ) uptake, photosynthetic pigments, proline content, and total soluble sugars content compared to the individual application of PGPR or PS and the untreated (control) plants. In addition, the combined application significantly ( P <0.05) increased peroxidase and catalase activities, scavenging the damage effects of the reactive oxygen species. Our data revealed that the combined application could activate the soil key enzymes, mainly dehydrogenase and urease, and boost soil microbial activity. Overall, the combination of PGPR and PS applications, as a simple and low-cost biological method, has shown a positive effect in terms of improving soil properties, enhancing plant growth, and increasing element contents of wheat under salinity stress.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73316099","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 agriculture mainly depended on the open field cultivation to produce the necessary food for human, but an urgent need was formed under the global overpopulation to produce more food using different farming systems such as soilless farming, protected cultivation, hydroponics, etc. Protected farming allows producing crops (food) under controlled conditions to modify any natural environment prevent/ restrict the plant growth and its productivity. This work focuses on the protected farming and its association with climate-smart-agriculture. Protected farming has several obstacles in the developing countries especially under using the low-tech protected farming technique. Climate-smart-agriculture is an agriculture, by which its productivity can be sustainably increased, its resilience to climate change can be enhanced, and greenhouse gases can be mitigated, as well as enhances achievement of national food security and development goals. The closed relationship between protected farming and climate-smart agriculture is needed to be investigated in more research. Therefore, this work reported on protected farming and its potential against changing climate. This is also a call by Environment, Biodiversity and Soil Security (EBSS) for receiving articles on protected agriculture under climate-smart agriculture approach, their challenges, their obstacles and the novel solutions in this concern.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84757252","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}

Thus, the sustainable alternative “like bio-nanofertilizers” for the mineral fertilizers, that protects and conserves the environment will be a global aim. The present investigation introduces a simple and a fully-automated technique for producing bio-nanofertilizers from abundant green materials. These nano-fertilizers were produced using plant extracts as a protocol for the biosynthesis of nanoparticles based-fertilizers. The innovative device can work automatically without human intervention by programming its units to produce homogeneous nanoparticles. Three plant extracts (i.e., Nerium oleander, Azadirachta indica, and Cinnamomum camphora) were selected to produce nano selenium using this device, and the nano-products were further investigated using both zeta potential and transmission electron microscope (TEM). Further investigations including more nano-fertilizers will be published in the future with more details for different kinds of nutrients.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73543523","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 sampling processes were carried out seasonally. The collected samples were subjected for a series of analyses, in terms of total and available contents of macro nutrients and potentially toxic elements (PTEs), biological investigation (pathogens contents) and chemical oxygen demand (COD) and biological oxygen demand (BOD). Water samples taken at most of the study sites during the year can be regarded acceptable for agricultural use, but only under particular conditions. On the other hand, these waters are not appropriate for agricultural use from a biological point of view. Enrichment factor (EF) values of the sediments were low for Mn, Zn, Co, B, Co, Cr, Ni and Pb in all seasons and at most sites. Unlike the EF values of the aforementioned PTEs, the enrichment factor for cadmium was generally, high at most sites within the four seasons. EF values of Pb were moderate at most sites. The bioaccumulation factor (BCF) values of the shoot of aquatic plants and BCF values of the roots were generally high for most elements in all seasons. Principal component analysis (PCA) revealed that these metals were originated from natural (Cd, Co, B and Cu) and anthropogenic (Fe, Zn, Mn, Cu, Ni and Cr) sources.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75068842","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}

Pbz is also used to decrease the canopy volume and increase the flowering strength of many crops. PBZ can shorten the plant height, increase the stem diameter and number of leaves as well. Pbz could be also used to control flowers blooming and fruits set. PBZ efficiency in plant tissue cultures have been reported as one of the most important inhibitory substances, which slow growth and decrease the numbers of subcultures. Moreover, Pbz has been widely applied in vitro to reduce growth and induce flowering. On the other hand, a lot of studies confirmed the promoting effect of Pbz for plants tolerance/resistance to different abiotic/biotic stresses. However, more studies concerning the ecotoxicology of Pbz in different environmental compartments are still needed to be investigated. In addition, the impact of Pbz on cultivated plants under combined stresses like heat-drought or drought-salinity under biotic stress is still needed to examine.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91314011","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}
