T HE NILE Delta is one of the oldest and largest deltas in the world covers 4 % of Egypt’s area and occupies 63 % of the Egyptian cultivated land. The present study focuses on the goods and services offered by Delta’s natural ecosystem. Thirty field trips were conducted to different locations to cover the study area from spring 2020 to summer 2022. Based on field observation and information gathered from residents and herbalists (60 people from the study area were interviewed, ranging in age from 30 to 60 years old) the goods, services and threats of the recorded species were assessed. Forty-nine were recorded and their roles in goods and services; identified threats that cover the gradual change in the study area were recorded. Recorded species offer many goods such as grazing (36 species), medicinal (26) and human food (15). Also, they provide environmental benefits that ruderal and segetal weeds are the most commonly offered service, followed by bank retainer (16 species) and weed controller (6 species). Thirty-six species (73% of recorded species) suffer from at least one type of threat; over-collecting and over-cutting were the most common threat (46.9%), then habitat loss (40.8%), browsing and over-grazing (34.7%), clearance for agriculture (24.5%) species) and disturbance by cars or trampling (10%). Authors recommended that Nile Delta natural flora need continuous monitoring and conservation, as this region faces deteriorating habitat loss and even extinction of plants; which offer many goods and services for humans and the environment.

O NE of the major factors significantly modifying plant physiology and ultimately causing a loss in crop productivity is water deficiency stress. Plant-based pigments are highly effective in enhancing growth and reducing the consequences of water stress. The present study aimed to identify the effects of copper chlorophyllin (Cu-Chl) at rates of 0, 1, and 2% on the growth, yield, and physiological traits of spinach plants of the variety Viroflay grown under three irrigation levels of 100%, 75%, and 50% crop evapotranspiration rates (ETc) in the 2020 and 2021 growing seasons. In comparison with full irrigation (100% ETc), deficit irrigation with 50% ETc drastically reduced plant growth parameters (height, leaf number, leaf area, and fresh and dry weight), yield, relative water content (RWC), leaf membrane stability index (MSI), electrolyte leakage (EL), chlorophyll a, chlorophyll b, carotenoids, Fe, and Cu content. However, the nitrate and oxalate content increased in the plants. All studied values were significantly higher except nitrate and oxalate content which were lower with Cu-Chl application, in comparison with those without Cu-Chl application. The present work demonstrated that the adverse effects of water deficit on growth, yield, plant water status, and photosynthetic pigments of spinach plants could be alleviated when using Cu-Chl application.

The current investigation is concerned with the removal of Gram-positive and Gram-negative pathogenic bacteria from aqueous solutions. The abundant and inexpensive natural resource, pomegranate dry peel (PDP), and its activated carbon (PDPAC) have been used as bio-adsorbents. Phosphoric acid (30%) was used to chemically activate the carbon at 800 ºC. The optimum contact time was 60min for the dry peel and 40min for the activated carbon at a pH range of 7.0 to 7.5 and 30 to 35ºC processing temperature. The adsorption isotherm of different bacteria was determined for both adsorbents and analyzed by three common isotherm models. The equilibrium results have matched well to the Langmuir equation and the maximal monolayer adsorption capacity was 12500, 14286, 20000, 1000 CFU/g with PDP and 25000, 25010, 33343, 20000 CFU/g with PDPAC for E. coli, S. enterica, S. aureus , and E. faecalis, respectively.

T HE use of local maize is still in high demand by farmers in Indonesia. The development of local maize needs to be discovered through a morphological approach. This study was to obtain seed characteristics and similarities of local maize from North Sumatra. Local maize accession seeds were taken by four districts/cities (Binjai, Serdang Bedagai, Deli Serdang, and Mandailing Natal) from North Sumatra, Indonesia from July to September 2022. A hybrid variety of maize was selected for comparison. Seed characteristics were measured in each accession with four replications. A descriptive-analytic method was selected in this study and data were analyzed using one-way ANOVA and followed by Tukey at P <0.05. Correlation analysis, similarity matrix, hierarchical cluster, and constellation plot were constructed in this study. The results showed that SB-1; DS-3; SB-4; and SB-2 accessions had higher seed characteristics than other accessions. The SB-5 accession had the nearest neighbors (0.743) and two accessions (BI-1; DS-2) were classified into one cluster with a hybrid variety. This finding indicates that several local maize accessions are nearest to the hybrid characteristics. A novelty of this study informed that local maize had an opportunity to be used in the fields.
