Abstract

With the scarcity, degradation of soils, the growing populations and the need to guarantee their food security, the valorization of gypsum soils widespread in arid and semi-arid regions is becoming a necessity. North African countries have a large part of their land area located in arid regions. It is therefore important to characterize the gypsum content using simple, rapid, economical and, environmentally friendly methods. Several methods have been proposed in the literature (chemical, thermogravimetric, and x-ray techniques). In this work, a comparison between two methods for gypsum determination in soils was undertaken. The first method of Coutinet is chemical and based on the use of BaSO4 for the precipitation of sulfate ions. The second method is Artieda method which is based on measuring the weight difference caused by the loss of crystalline water from gypsum molecules between the temperatures of 70 and 90 °C. To achieve the objective of this work, forty-three soil samples were analyzed. They were taken from two arid regions (Ouargla and Touggourt) located in the northern Sahara (Algeria). The soils contain gypsum accumulations. The results showed that most of the samples are slightly gypsiferous, with 36 and 32 samples for the Coutinet and Artieda methods respectively. A strong positive correlation (R2 = 0.95) exists between the results of the two methods studied. For gypsum contents higher than 2 %, the correlation coefficient is 0.94. However, for samples with contents less than 2 %, the correlation is very weak with R2=0.19. The Artieda method is thus encouraged for the gypsum quantification in soils of arid regions. This method is easy, requiring simple laboratory equipment (mainly a ventilated oven and a precision balance). Chemical methods have the disadvantage of being time-consuming and using expensive chemicals that are dangerous for the environment and human health.

Abstract

Soil salinity poses a significant challenge to agricultural productivity, necessitating precise measurement methods. Rather than relying on complex determinations like saturated paste extracts (ECe), a practical alternative involves assessing soil salinity through the Electrical Conductivity (EC) of soil-water extracts. This simplified yet reliable method is crucial for understanding the impact of soil salinity on agricultural yields. To improve accuracy in representing soluble salts relevant to plant growth, the conversion of EC from soil water extracts to ECe becomes pivotal.In an experimental study, a clear relationship was sought between the Electrical Conductivity (EC) of saturated paste extracts (ECe) and the ratios found in soil-water extracts (1/2.5 and 1/5). Fifty samples of coarse-textured soil were collected from the Djamâa palm grove in Sidi Yahia village, located in the Oued Righ region within the Djamaa Zone. The analysis of the collected data revealed compelling findings, indicating a robust and statistically significant correlation between values obtained from ECe and those derived from EC1/2.5 and EC1/5 (correlation coefficient of R = 0.93 and 0.91, at a significance level of P = 0.05). These results highlight the promising potential of accurately estimating ECe in coarse-textured soils by employing EC1/2.5 and EC1/5, paving the way for streamlining assessment methodologies for soil salinity. This study not only elucidates the correlation between conductivity measures but also proposes a practical means to estimate soil salinity more efficiently. The findings contribute to informed decision-making in agricultural practices within the Northern Sahara's Djamâa palm grove and similar regions, offering valuable insights for sustainable soil management.

Abstract

The search for alternatives to chemical pharmaceutical products remains an urgent and crucial step for humanity. In this regard, the use of plants presents an ideal approach for such biological studies. Arbutus unedo L., which belongs to the family Ericaceae, is one of the species that holds significant importance in traditional pharmaceutical uses. In Algeria, the use of this species in traditional treatment is generally rare. Therefore, this study aims to highlight its medicinal importance and the proper method for extracting its bioactive elements. To achieve this, the biological activity of leaves including total phenolic content (TPC), DPPH assay, and total flavonoid content (TFC), were assessed under four different drying temperatures (shade-drying, sun-drying, 40°C and 60C°) and two extraction methods after maceration (centrifugation, filtration). The results have indicated that these processes have affected the final accumulation of polyphenols and antioxidant activity in the leaf extracts. Additionally, it has been highlighted that the centrifugation method extracts a higher biochemical amount, especially after drying at 40°C. Furthermore, Arbutus unedo L. leaves should be considered a promising source of natural compounds to be used as ingredients in various fields.

Abstract

Fruit flies (Diptera: Tephritidae) are cosmopolitan, species-rich, and yet poorly studied in Algeria, particularly in the agro area of Djelfa. We sampled fruit flies in orchard containing three types of trees apricot, fig and grapes at each site, using the yellow traps. Results show that the orchard differed significantly in species richness, abundance, diversity and evenness. A total of 956 individuals distributed by nine species of Diptera, including four species of fruit flies are collected. The results revealed that most abundant species are Drosophila melanogaster at the apricot fruit site (RA%=28.32%), Zaprionus indianus at fig fruit site (RA%=34.74 %) and Tephritis praecox at the grapes fruit site with (RA%= 51.61 %). The orchard selected a greater number of species and individuals, and higher diversity indices H′=2.40 bits; 2.32 bits and 2.02 bits. Statistically, the result of stepwise multiple regressions revealed a very strong correlation between the number of fruit fly species and the temperatures with (r=93.1%) and (Sig .000**). Thus, fruit flies appear to have rather arrow with the host plant requirements and their phenology was correlated with environmental differences. Our study highlighted for; the first time; the presence of Trupanea amoena in Algeria. This important and substantial preliminary work on this new species in Algeria provides a solid basis for future research and extension of the study in particular for monitoring and control of this dreaded agricultural pest.

Abstract

abbage (Brassica oleracea var. capitata) is the most important winter leafy vegetable in the world and belongs to the Cruciferae family. An experiment was conducted at the Horticultural farm of Gauradaha Agriculture Campus, Tribhuwan University, Jhapa, Nepal from 26th December 2022 to 2nd April 2023 to evaluate the different organic and inorganic fertilizer combinations on the growth and yield of cabbage (Brassica oleracea var. capitata L. cv. Green coronet). The experiment was conducted as a randomized block design with 7 treatments replicated 3 times and the treatments are T1: 25-ton FYM/ha, T2: 25-ton PM/ha, T3: 25-ton FYM/ha + NPK (RDF), T4: 25-ton PM/ha + NPK (RDF), T5: 20-ton FYM/ha + 10-ton PM/ha + NPK (RDF), T6: 10-ton FYM/ha + 20-ton PM/ha + NPK (RDF) and T7: control. Significant variation was found among the treatments. The result showed treatment had a significant role in different parameters. T3- The highest number of leaves, T5- the highest (leaf area, weight with roots, net head yield, horizontal head diameter), T4-highest (plant height, gross yield), T6- highest (stem girth, vertical head diameter) was obtained. On the result basis T5 (20-ton FYM/ha + 10-ton PM/ha + NPK (RDF) can be adopted as sustainable crop production. This study not only provides valuable insights into optimizing cabbage production but also underscores the importance of tailored fertilizer combinations for sustainable agriculture. Furthermore, the findings contribute to the broader discourse on enhancing crop yield while minimizing environmental impact. By elucidating the efficacy of specific fertilizer blends, this research paves the way for more efficient and eco-friendly farming practices, thereby promoting food security and environmental sustainability on a global scale.

Abstract

The fruit of the date palm, Phoenix dactylifera L. is extensively consumed in Arabian countries and is esteemed for its nutritional attributes, boasting high carbohydrate content and specific vitamins. This study aims to assess the antioxidant potential of polysaccharide extracts from the date palm fruit (Phoenix dactylifera L.) from two selected cultivars, Tazerzait “Azerza” and Deglet-Nour, originating from the Ghardaia region. Crude polysaccharides were extracted from the dates using distilled water followed by ethanol precipitation. Yields from this process were 3.14% for the Tazerzait cultivar and 4.75% for the Deglet-Nour cultivar, indicative of significant polysaccharide content, known for their diverse health benefits. Antioxidant activity was evaluated in vitro through DPPH and ABTS assays. Polysaccharide extracts exhibited noteworthy antioxidant activity, notably the Tazerzait variety. In the DPPH assay, the Tazerzait extract displayed an IC50 value of 4.66 mg/mL, indicating effective scavenging of free radicals. Moreover, in the ABTS assay, the extract demonstrated even more potent activity, with an IC50 value of 0.49 mg/mL, underscoring its robust antioxidant properties. These results underscore the strong antioxidant potential of Tazerzait polysaccharides. Polysaccharide extracts from the date palm fruit, particularly from the Tazerzait cultivar, exhibit significant antioxidant activity, highlighting their potential as natural antioxidants. This suggests avenues for their utilization in pharmaceutical and food industries to enhance human health.
