alinity is one of the most brutal environmental factors limiting the productivity of crop plants. 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.

THE LAST centuries, agriculture depended on the fertile soils beside the river, which helped the ancient humans to establish many civilizations like the Egyptian civilization. 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.

Samples of water, sediments and aquatic plants were collected from different sites along EL-Gharbia main drain. 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.

A field experiments were carried out during two successive seasons 2019 and 2020 in a private farm at Belqas district, Al-Daqahlia Governorate, Egypt to assay the effect of various sources of organic fertilizers (farmyard manure, compost, chicken manure and spent coffee ground) added either solely or combination with biofertilizers (N-fixers and PK-dissolving bacteria) on the growth performance and productivity of potato plants. Results showed that the soil amended with chicken manure (24.7m3/ha.) and inoculated by dual biofertilizers i.e. Paenibacillus polymyxa as nitrogen fixing bacteria and Enterobacter cloacae as phosphate and potassium solubilizing bacteria that introduced as talc-based formulation containing mixed strains, significantly enhanced remaining nutrients in the soil post-harvest; Moreover, densities of bacterial population at 90 days’- time interval significantly increased. Also, the highest vegetative growth, yield attributes and tuber quality were recorded for the same treatment. On other hand, this treatment recorded the lowest nitrate content for both seasons. It is worth mentioning that soil amended with spent coffee grounds (27.17m3ha.-1) with bacterial inoculation has a positive effect on improving soil fertility and potato productivity.
