Camel milk: Composition, properties and processing potential

2025-04-07T23:38:57+02:00

Camel milk serves a crucial role in arid regions, providing exceptional nutritional and health benefits. It is characterized by a lower cholesterol and sugar content compared to the milk of other ruminants, along with a high concentration of minerals such as sodium, potassium, phosphorus, and manganese, and elevated levels of vitamins C and B3. Furthermore, camel milk contains higher levels of protective proteins such as lactoferrin, lactoperoxidase, immunoglobulins, and lysozyme. This specific composition underpins the use of camel milk in the treatment of various diseases. Numerous studies have confirmed its diverse functional properties and health benefits, including antimicrobial, anticancer, antioxidant, anti-inflammatory, and antidiabetic effects. However, despite these significant advantages, its industrial transformation into dairy products remains a major technical challenge. This is due to its low κ-casein content, the large size of its casein micelles, and the absence of β-lactoglobulin, characteristics that complicate the production of cheeses, yogurts, and other dairy products. Finally, specialized technologies and future research are required to optimize transformation processes and fully harness the potential of this milk with exceptional properties.

Productivity of Chia crop in the sandy soils of East Delta, Egypt

2025-04-08T10:46:41+02:00

Chia (Salvia hispanica L.) crop is a newly introduced herbaceous plant to the Egyptian cropping system. No information is available on water requirements of chia crop under Egyptian conditions. A field experiment was conducted to determine the effect of irrigation treatments (I_Farmer, I_Growth-stage, I_120%ETo, I_100%ETo, I_80%ETo, and I_60%ETo) on chia seed yield, plant height, total carbohydrates, total protein, total oil content, seed's nutrients, applied irrigation water (AIW), water productivity (WP), and yield response factor (Ky). Results showed significant effect of the irrigation treatments on all tested parameters. Average AIW values for the respective treatments were 8036 m³/ha, 7492 m³/ha, 6081 m³/ha, 5228 m³/ha, 4376 m³/ha and 3523 m³/ha. The highest average seed yield of 3.15 t/ha was recorded for I_120%ETo treatment, while the lowest value of 2.00 t/ha was recorded for the I_60%ETo treatment. The highest WP of 0.598 kg/m³ was recorded for I_80%ETo. The Ky value of 0.78 was obtained. Therefore, applying appropriate agronomic management (e.g. proper amounts of irrigation water, and fertilizers through drip-fertigation technique) can achieve high chia seed yields. In case of water shortage, applying appropriate agricultural practices and I_80%ETo can save 46% (3660 m³/ha) of AIW without significant reduction in seed yield.

Impact of foliar application of moringa leaf extract on growth and yield of different cultivars of cucumber (Cucumis sativus) in Nigeria

2025-04-08T12:22:29+02:00

Extreme dependency on synthetic fertilizers and other agricultural inputs like pesticides and herbicides poses risks to environmental and health hazards and has driven the quest for more justifiable and eco-friendly approaches. A field experiment was conducted during the 2024 growing season at Federal University Dutse Teaching and Research Farm, to examine the potential of Moringa Leaf Extract (MLE) as a natural, plant-based biostimulant to improve cucumber (Cucumis sativus) productivity. Three cucumber varieties were used Monalisa F₁, Saira F_1, and Poinsett, and were laid in a Randomized Complete Block Design with three replications. Data on crop growth and yield components were collected and analyzed. Except for the Number of branches and Number of fruits per plant, MLE application significantly enhanced most traits of cucumber, including days to 50% flowering, number of Fruit diameter, vine length, and number of leaves, Poinsett variety had high fruit length compared to Monelisa F1 and Saira F1, while Monalisa F₁ had a high percentage of flowering compared to Poinsett and Saira F1. The application of MLE proved to be an effective biostimulant offering an alternative and environmentally friendly approach to enhance the productivity of cucumber in Sudan Savannah Zone of Nigeria.

Trait correlation and heritability analysis in diverse upland rice (Oryza sativa) genotypes

2025-04-08T12:46:18+02:00

study evaluated agronomic traits' performance, correlation, and heritability in ten rice (Oryza sativa L.) genotypes grown at the Teaching and Research Farm of Federal University Dutse during the 2024 rainy season. The experiment followed a randomized complete block design with three replications. Analysis of variance revealed significant differences (p < 0.01) among genotypes for most traits, indicating substantial genetic variability. FARO 44 exhibited the highest grain yield per hill (145.3 g), followed by FARO 16 (138.6 g) and FARO 52 (140.7 g), while FARO 47 recorded the lowest yield (103.5 g). Days to heading (DTH) and days to flowering (DTF) showed high broad-sense heritability (99.9%), along with floret per panicle (99.6%) and grain yield per hill (98.5%), suggesting strong genetic influence. However, panicle length (59.4%) and fertility percentage (55.5%) had moderate heritability, implying environmental effects. Correlation analysis revealed a strong positive association between DTH and DTF (r = 0.970**) and between plant height and tillers per hill (r = 0.610**). However, plant height negatively correlated with DTH (r = -0.430*) and DTF (r = -0.405*), while grain yield exhibited weak associations with most traits. These findings highlight the potential for selecting high-yielding genotypes based on traits with strong heritability, particularly floret per panicle and grain yield per hill. The results provide useful insights for breeding programs aimed at improving rice productivity under similar agroecological conditions.

Essential Oils: Antifungal activity and study Methods

2025-04-08T11:20:51+02:00

Essential oils (EOs) are natural, volatile compounds extracted from plants, known for their diverse biological properties, including potent antifungal activity. This review explores the antifungal mechanisms of EOs, their efficacy against human and plant fungal pathogens, and their applications in medicine, agriculture, and food preservation. EOs disrupt fungal cell membranes, inhibit ergosterol biosynthesis, induce oxidative stress, and interfere with mitochondrial function and enzymatic pathways, leading to fungal cell death. Their broad-spectrum activity makes them promising alternatives to conventional antifungals, particularly in the face of rising antifungal resistance. Synergistic effects with conventional drugs, such as azoles and polyenes, further enhance their therapeutic potential. However, challenges such as variability in composition, stability, sensory impact, and regulatory hurdles limit their widespread adoption. Advanced delivery systems, including nanoencapsulation and emulsification, are being explored to improve EO stability and efficacy. In agriculture, EOs show promise as biocontrol agents against crop pathogens, while in food preservation, they inhibit spoilage fungi and extend shelf life. Future research should focus on optimizing EO formulations, conducting in vivo and clinical studies, and developing regulatory frameworks to facilitate their integration into mainstream applications. By addressing these challenges, EOs can emerge as safe, sustainable, and effective antifungal agents, offering innovative solutions across multiple industries.
