In the present study, sixteen bacterial isolates were collected and identified from the rhizosphere soil of the bean plant (Phaseolus vulgaris), named BB-1 to BB-16. Out of the sixteen bacterial isolates, six isolates showed positive activity of phosphate solubilization ability, three bacterial isolates were found positive for ammonia production, six were positive for Indole acetic acid (IAA) production, three could solubilize potash, three bacterial isolates produced cellulase, six exhibited positive for chitinase, five were tested positive for amylase and four bacterial isolates were positive for protease activity. Hydrogen Cyanide (HCN) production was noticed by the bacterial isolates BB-7only. The fungal pathogen such as Aspergillus terreus, and Penicillium rubidurum was resistant to most bacterial isolates, whereas bacterial isolate BB-3 showed sensitivity against Penicillium rubidurum. Their quantitative phosphate solubilization ability was 47.5-77.8 µg/ml, ammonia production was between 2.45 - 3.45 mg/l, and IAA production was 22.5 -29.5 µg/ml. Of the sixteen bacterial isolates, one bacterial isolate, BB-7, was positive for most of the tests and identified as Pantoea agglomerans. Plant growth-promoting activity of the isolate showed that in comparison to the control rice plant, higher root and shoot growth was achieved in rice pot inoculated with P. agglomerans culture

The study aimed to investigate the impact of different concentrations of aqueous suspension of bentonite nanoparticles (ASBN) on the productive performance of broiler chickens. The research was conducted at the University of Jordan poultry farm in Almuwaqar research station. A total of 240 Ross 308 broiler chickens were distributed among four treatments, with three replicates per treatment. Treatment T1 was the control, while T2, T3, and T4 received 1%, 2%, and 3% of ASBN, respectively. The study found that the use of ASBN at levels of 1%, 2%, and 3% significantly (p>0.05) improved the growth performance of broiler chickens. The lowest feed conversion ratio (FCR) was observed in T2 (1% ASBN) on day 28, indicating better feed efficiency. However, carcass characteristics parameters, such as dressing and cut percentages, were not significantly influenced by ASBN treatment. Interestingly, T4 (3% ASBN) resulted in a higher weight of the breast compared to the other treatments. The study concluded that using ASBN at levels of 1%, 2%, and 3% can enhance the growth performance of broiler chickens without negative impacts on their carcass characteristics.

The objective of this study was to assess the effect of feeding whole or ground barley grain on Awassi lambs. Twenty-six lambs (17.5 ± 1.28 kg) were randomly assigned to one of two treatments (13 lambs/treatment) on whole or ground barley grain. Lambs were housed individually and fed twice daily for 47 days. Initial body weight (BW) was not different when the experiment was started, as well as for the BW at the end of the experiment. At the same time, total weight gain (TWG) and the average daily gain (ADG) were significantly higher for lambs fed a diet containing ground barley grain than lambs fed a diet containing whole barley grain. The digestibility of dry matter, crude protein, neutral detergent fiber, and acid detergent fiber was greater in ground barley than in whole barley treatment. Nitrogen intake and nitrogen in the urine were similar in both lamb groups. At the same time, fecal N was greater in the group of lambs fed whole barley grain in their diet, but less amount and percentage of N retained in the body for the same group of lambs (whole grain). Blood Urea N was not affected by the dietary treatment, while blood glucose was higher in lambs fed ground barley grain compared to lambs fed a diet containing whole barley grain. In conclusion, feeding ground barley contained diet had a significant improvement in intake, digestibility, and N retention, without any negative effects on ruminal pH.

The experiments were conducted in tomato fields and greenhouses in 2019 and 2020 to evaluate the allelopathic effects of white and red cabbage with and without mulch to control johnsongrass. The effect of these methods on Johnsongrass life cycle durations, density, length, fresh and dry weight of stems, and rhizomes were determined. Also, the effect of the treatments on the quantity and quality of tomato production was evaluated. In the greenhouse experiment, tomato seedlings were planted with johnsongrass seeds and rhizomes and were treated with plants' aqueous extracts at concentrations of 2, 5, and 10%. The germination and dry weight reduction percentage of johnsongrass were calculated. Isothiocyanates contained in white and red cabbage were identified by GC-MS. White and red cabbage with mulch reduced johnsongrass density by 69.1 and 65.9%, while the dry weight of stems and rhizomes were reduced by 78.2-74.2% and 71.3-68.0%, respectively. White and red cabbage with mulch treatments achieved an increase in tomato production by 632.1 and 621.8%. According to GC-MS analysis, the predominant isothiocyanate in white cabbage was 3-(methylsulfinyl) propyl (23.43%) and 4-(methylsulfonyl)butyl (10.79%) in red cabbage. The results of these experiments confirm that both white and red cabbage have allelopathic potential that can be used in weed control.

This study examined the microbial quality of tabbouleh, a popular Middle Eastern salad, at various restaurants in Amman, Jordan. Sixty samples were collected from 15 restaurants at two different intervals (October (interval I) and December (interval II)), with two samples taken from each restaurant. Additionally, two reference samples were prepared under hygienic conditions and tested for comparison purposes. The moisture content of the samples ranged from 65.2% to 85%, with an average of 76.8%. The pH ranged from 3 to 4.2, with an average of 3.5, and the acidity ranged from 0.5% to 1.1%, with an average of 0.8%. The microbial counts in interval I for aerobic plate counts (APC), coliform counts (CC), and lactic acid bacteria counts (LAB) counts. LAB averaged 5.5, 4.1, and 5.2 log10 CFU/g, respectively. While in the second period, it was 5.3, 3.5, 4.1, and 5.7 log CFU/g, respectively, with a few Staphylococci bacteria (<1 log CFU/g). Reference samples had significantly lower counts of APC, CC, LAB, and yeast counts (YC) 2.7, <10, 1.9, and 2.6 log10 CFU/g, respectively indicating that commercial tabbouleh was generally prepared without following proper hygiene procedures. Staphylococcus aureus counts, which are sensitive to low pH, were < 10 log10 CFU/ g in all the collected samples. Counts of all microorganisms were significantly higher in interval I samples when compared to interval II samples, suggesting that the microbial quality of tabbouleh deteriorated over time as affected by relatively higher seasonal temperatures. This study highlights the importance of proper hygiene practices during the preparation of tabbouleh and the need for regular monitoring of its microbiological quality.

All parts of the world are vulnerable to natural disasters. Flood hazards are the most typical causes of damage. People act preventatively up to the point where the predicted advantages (avoiding losses) outweigh the expenses, and this is influenced by knowledge (most of which is embedded in pricing) and limits on their resources. In addition, people vary in how much danger they're willing to take. This study analyses risk perception and attitudes that determine the flood risk response of the people in Jammu and Kashmir. A stated preference survey is carried out, with the potential impact of information being taken into account. Results indicate that several wealth composition variables, including housing value and annual income, have favorable impacts on risk perception. Whereas other factors, such as land value and durable goods value, negatively influence people's perceptions of risk. Additionally, other variables such as 'floods are exogenous to human control' show a very poor correlation with the willingness to pay for flood risk in the area. By their very nature, those who often engage in risky behavior include a need to cope with the occasional positive results.

The present study aims to determine the effect of bioactive compounds (total phenolic, total flavonoids, and antioxidant activity) of Spirulina platensis powder and its pasta products on kidney and liver diseases in rats. Pasta preparation enriched in spirulina powder with a standard treatment formulation. Pasta was supplemented by adding Spirulina platensis powder at different levels (5, 10, 15, and 20 %). The results indicated that rats treated with spirulina had lower plasma levels of ALT, AST, ALP, Albumin, creatinine, and total bilirubin after the end of the experiments. However, liver glutathione (GSH) concentration was markedly decreased as compared to the control group. In conclusion, pasta enriched with spirulina improved liver and kidney functions and enhanced oxidative stress indices. Additional studies are necessary to test the application of Spirulina platensis in other contexts.

The present study during seasons in 2022 to study the extracts effect of moringa (Moringa oleifera) leaves at (2-, 4-, and 6-ml l-1), garlic (Allium sativum) cloves (5, 10, and 15 ml l-1), and turmeric (Curcuma longa) at (5, 10, and 15 ml l-1) sprayers on Salakhani pomegranate. Thirty uniform trees were selected, and each tree was considered as an experimental unit using a randomized complete block design (RCBD) with three replicates. The results showed that spraying pomegranate trees with moringa leaves extract with 2 and 6 ml l-1 and all doses of turmeric extract significantly increased surface area and dry weight of leaf, except 6-ml L-1 and 15 ml l-1 of morenga leaves extract of turmeric extract increased leaf dry weight non-significantly compared to the control. As well as all garlic clove extract levels increased the surface area and dry weight of the leaf significantly compared to the control. Moreover, all plant extract treatments were effective in increasing the number of fruits and yield per tree compared to the control. Additionally, most plant extract treatments improved all chemical parameters including total soluble solids, titratable acidity, pH, total sugar, and anthocyanin content as compared to the control.
