A FIELD trial was conducted to assess the effect of humic acid concentrations (0, 1.5, 3.0 and 4.5 g/l) on growth, yield and volatile oil constituents of fennel sown on 15th October, 1st November and 15th November during the two successive seasons of 2017/2018 and 2018/2019. The earliest date (15th October) recorded the best results regarding all fennel growth, yield and fruit constituents of volatile oil yield. Foliar application of humic acid in high concentration (4.5 g/ml) showed significant impact on plant height, branch number/plant, stem diameter, number of umbels/plant, fruit yield/plant, total fruit yield/feddan, volatile oil percentage, volatile oil/plant and volatile oil/feddan during both seasons. Volatile oil of fruits collected from plants sown in mid-October induced the highest percentage of anethole (74.96 %) and the lowest percentage of estragole (15.37%) in comparison with the plants sown in the beginning and middle November. The higher concentration of humic acid increased the percentage of anethole comparing with other concentrations. The foliar application by humic acid in high concentration of fennel sown in mid-October seems to be the best combination for getting higher fruit yield and high quality of volatile oil.

One of the most impact issues in recent years refers to the COVID-19 pandemic, the consequences of which thousands of deaths recorded worldwide, are still inferior understood. Its impacts on the environment and aquatic biota constitute a fertile field of investigation. Thus, to predict the impact of the indiscriminate use of azithromycin (AZT) and hydroxychloroquine (HCQ) in this pandemic context, we aim to assess their toxicological risks when isolated or in combination, using zebrafish (Danio rerio) as a model system. In summary, we observed that 72 h of exposure to AZT and HCQ (alone or in binary combination, both at 2.5 μg/L) induced the reduction of total protein levels, accompanied by increased levels of thiobarbituric acid reactive substances, hydrogen peroxide, reactive oxygen species and nitrite, suggesting a REDOX imbalance and possible oxidative stress.

The objective of this study was to evaluate the effect of roasting at 160°C for 5, 10 and 15 minutes on physicochemical properties, lipid oxidation, fatty acids profile, rancimat value, conjugated dienes and conjugated triene content of Giza 32 and Shandaweel 3 sesame seeds varieties. Results showed that all studied samples contained moisture (3.60 - 5.98%), crude protein (22.92 - 24.31%), oil (51.68 - 55.26%), fiber (7.12 - 8.14%), ash (3.92 - 4.73%), and carbohydrates (9.63 - 12.01%); in raw and roasted sesame seed varieties (RSS). Data revealed that acid value, peroxide value, TBA, conjugated diene and conjugated triene, increased gradually by roasting treatments of seeds, while the iodine value was slightly decreased by roasting. A little changes in the saturated and unsaturated fatty acids were found during roasting. Palmitic acid was the predominant saturated fatty acids followed by stearic acid, while oleic and linoleic acids recorded the highest levels among unsaturated fatty acids in both sesame oils. Data also revealed that the thermal stability (Rancimat value) of sesame oils was enhancement by roasting treatments.

ABSTRACT:The current study aimed to investigate the effect of increasing feed frequency as a managerial method for both males and females’ California rabbits on growth performance, carcass characteristics and meat quality. Thirty-six males and Thirty-six females of six-week-old were used. Both males and females were divided into three treatments. The first treatment (once) feed was offered once a day at 8 am second treatment (twice) feed was offered twice a day 8 am and 4 pm and third treatment (thrice) feed was offered three times a day at 6 am 12 pm and 6 pm. Growth performance measurements were recorded daily (Feed intake, body weight, daily gain and feed conversion ratio). At the end of experiment (8 weeks) all rabbits (males and females) were slaughtered after 8 hours of fasting. Carcass weight, carcass parts and individual muscles weight were recorded. The current study showed that, feed frequency significantly (P0.001) improved feed intake in both males and females. Subsequently, increasing number of feeding increased (P0.01) final weight, total gain and average daily gain, without any effect on feed conversion ratio in both males and females. Moreover, increased body weight of males and females fed more than one time a day resulted in an increase (P0.01) in carcass weight and carcass parts. In addition, increased feed frequency decreased (P0.05) carcass’s fat. The current study showed that increasing feed frequency in both males and females improved rabbits’ performance, carcass characteristics and meat quality.

Metal contamination of soils is a main source of hazard materials in food chain. Biochar is a promising agriculture tool to improve plant yield and enhance quality of vegetable crops. Three rates of biochar (C =0, BC1 = 5 and BC2 = 10 ton ha−1) were added to a metal-polluted soil before the cultivation of tomato (Solanum lycopersicum cv Super). The non-edible part of tomato accumulated 80 and 84 % of Cu and Zn, while 20 and 16 % was transferred to the fruit. Whereas the non-edible part of tomato kept 99.9 and 99.8 % of Pb and Cd, less than 0.1 and 0.2 % were moved to tomato fruit. Metal concentrations in tomato tissues as affected by biochar application found to decrease in the order: C>BC1>BC2. BC1 and BC2 significantly increased the tomato fruit yield by 20 and 30 %, respectively, above C treatment. BC2 increased the total acidity, TSS, vitamin C and lycopene in the juice of tomato by 33, 29, 39 and 24 % compared to the control. Biochar increased essential nutrient availability and uptake and minimized those of the toxic element. For improve tomato quality and productivity, it is recommended to apply biochar to metal-contaminated soils.

Availability of water for food production is a global concern; thus, increasing water productivity has been become a necessary. Deficit irrigation is a good strategy to increase water use efficiency, but it may affect negatively on plant physiology and crop productivity. Little is known about the effect of marine algae extracts on water stress resistance and yield of onion grown on semiarid regions. Therefore, field experiments were conducted in 2018 and 2019 growing seasons to study the effect of foliar application of marine alga (Amphora ovalis) extracts (at rate of 0, 3, 6 or 9%) on onion grown under normal irrigation (80% of available soil water) or water stress (50% of available soil water). The field experiments were laid out in a split-plot design with four replicates. The highest dose of algal extract sprayed on onion grown under water stress significantly (P 0.05) increased N, P, and K uptake by 116, 113, and 93% compared to the unsprayed plants. The application of 9% algal extract for onion grown under water stress significantly (P 0.05) increased the bulb yield by 67 and 102%, respectively, in 2018 and 2019 growing seasons.Water stress reduced the chlorophyll production as a result of directing most of plant’s energy to produce water-resistant materials such as proline and phenols.Algal extract reduced the negative effects of water stress and caused significant increases in onion growth and yield.
