Implementing the deficit irrigation pattern has become a major strategy in crop production systems. However, using less water than is required to irrigate crops is associated with changes in plant physiology and lower productivity. Therefore, the current research aimed to assess the integrated effect of humic acid and cytokinin on faba bean under water deficit. Under two irrigation levels (full irrigation, FI and deficit irrigation, DI), two humic acid treatments (without addition, H₀ and with addition of 10 kg ha⁻¹, H₁₀) and two cytokinin concentrations (without spray, C₀ and spraying with 25 mg L⁻¹, C₂₅), faba bean growth, physiology, and productivity were evaluated. The experiment was implemented for two winter seasons of 2019/20 and 2020/21 and performed in a split–split plots design with three replicates. The findings revealed that under low water supply (DI), H₁₀ plus C₂₅ was the most efficient treatment for enhancing faba bean growth. All physiological faba bean traits estimated under DI showed remarkable increases with the application of H₁₀ plus C₂₅ in both seasons. The increases in proline, catalase, and total soluble sugars under DI due to H₁₀ plus C₂₅ were 31.4 and 31.8%, 51.9 and 55.1% as well as 43.8 and 46.6%, in the first and second seasons, respectively. There was no significant difference between FI × H₁₀ plus C₂₅ and DI × H₁₀ plus C₂₅ in phosphorus content in both seasons. FI × H₁₀ plus C₂₅ and DI × H₁₀ plus C₂₅ in the second season produced a similar number of pods plant⁻¹ and seed yield of faba bean. Conclusively, the combined application of humic plus cytokinin achieved physiological and nutrient homeostasis, adjusting the biochemical compounds in faba bean under water deficit.

The positive benefits of consumption fruit and vegetable are well documented in studies of health and body weight maintain. A cross sectional study was conducted utilized street based survey among 960 female students at King Faisal University in AL-Hasa, Saudi Arabia, to investigate the daily consumption of fruits and vegetables and the psychosocial factors related to the consumption. Seventy-eight percent of students consuming =5 servings/day, majority of them are in the normal BMI category. For psychosocial factors the higher consumption group more knowledgeable about the daily consumption of fruit and vegetable, and had more confidence in eating fruit and vegetables under difficult circumstances with significant differences between the groups (P=0.000, P=0.045; respectively). Self efficacy was significantly predictor for recommended daily fruit and vegetable consumption (?=0.303, SE=0.023, P=0.000), but perceived barriers and knowledge not predictor for recommended daily consumption. The results of this study can be useful to design an intervention to promote fruit and vegetable intake among this target group.

In the current study, we investigated the effect of potassium humate (Kh) and salicylic acid (SA) in mitigating the salinity stress of common bean plants. Common bean seedlings were treated with 0.2 g/L SA as a foliar application and 0.3 g/L Kh as a soil application individually or in combination. After 7 days of germination, plants were treated with 50 mM NaCl and normal water as a control. Our results indicate that salt treatment reduced the plant growth (fresh and dry shoots and roots), leaf pigments (total chlorophyll and carotenoids), ascorbic acid (AA), glutathione (GSH), and potassium (K) contents. On the contrary, proline content; sodium (Na); hydrogen peroxide (H₂O₂); superoxide anion (O₂^•−); and antioxidant enzymes, including catalase (CAT), peroxidase (POX), and superoxide dismutase (SOD), were increased by saline stress. However, applying either individual Kh and SA or their combination stimulated seedling growth under salinity stress by increasing growth parameters, leaf pigment contents, AA, GSH, proline content, K content, and antioxidant enzymes compared with the control. Additionally, Na content, H₂O₂, and O₂^•− were reduced by all applications. The application of the Kh (0.3 g/L) + SA (0.2 g/L) combination was more effective than using the individual compounds. In conclusion, applications of Kh + SA can mitigate salt stress and improve the seedling growth of common bean.

Prickly pear peel makes up around half of the fruit and is typically thrown away, creating an environmental issue. Due to its high bioactive chemical content, prickly pear peel can easily be used as a functional and nutraceutical ingredient in several food recipes, such as baked products. This study’s objective was to determine whether prickly pear peel flour (PPPF) could successfully be combined (5, 10, and 15%) with wheat flour to make cakes, by analyzing the physical and chemical characteristics of the cakes and performing a descriptive sensory analysis. Prickly pear peel flour contains high amounts of fiber, ash, carbohydrate, phenolic, flavonoid compounds, or antioxidant activity. In addition, PPPF contains high amounts of magnesium, calcium, sodium and potassium. The ethanolic extract of prickly pear peel revealed the presence of 11 phenolic compounds using UPLC-MS/MS. The main constituents in the peel extract were isorhamnetin (27.1%), eucomic acid (19.6%), kaempferol (14.07%), 3-O-Methylquercetin (13.7%), Feruloyl-D-glucose (10.01%) and piscidic acid (8.89%). Results showed that adding PPPF significantly enhanced the amount of fibers, total polyphenols, flavonoids and minerals in the cakes prepared by the addition of 5, 10 and 15% PPPF as compared to the control cake. Moreover, the addition of different levels of PPPF increased antioxidant activity (DPPH and ABTS%) and decreased thiobarbituric acid reactive substances (TBARS) in cakes as compared to the control cake. The descriptive sensory analysis ultimately revealed that cakes made with 10% prickly pear flour received a higher score for their smell, taste or color. In conclusion, prickly pear peel has antioxidant potential and contains biochemical compounds that can be utilized in the enhancement of functional foods and also help to reduce the waste accumulation that causes environmental issues.

The current study investigates the feasibility of preparing Arabic bread from wheat flour, sweet potato flour, or peeled sweet potatoes based on the nutritional values, technological characteristics, and sensory properties of the final products. First, we analyzed the proximate, elemental, total and individual phytochemical compositions of the raw materials and bread samples. The analysis showed that potassium, calcium, and phosphorus were higher in peels than pulp, in the same manner to the total phenolics, flavonoids, and anti-radical scavenging activities. Phenolic acids and flavonols were quantified, where p-coumaric, feruloyl-D-glucose, eucomic, gallic, and ferulic acids were measured as major phenolic acids in either peels or pulp flours, and their quantities were higher in the peels. Furthermore, we evaluated the effects of wheat substitution on the properties of the dough blends and their final bakery. The results indicated that the fortified samples’ nutritional and rheological properties were significantly improved, while their sensory qualities were comparable to those of the control. Thereby, the fortified dough blends presented higher dough stabilities, indicating a wider range of applications. Additionally, after the heat treatment, the fortified breads maintained significantly higher total phenolic, flavonoid, anthocyanin, and carotenoid contents, and total antioxidant activities, implying their accessibility for humans upon consumption.
