“…These results may be due to addition of organic fertilizers, which affect soil properties and improves roots spread and growth, as well as its role in increasing nutrients availability, as well as increasing various activities of microorganisms and their secretions, which may be rich in important growth regulators, and thus improve vegetative growth characteristics and thus influence the fruiting characteristics [20]. These results are consistent with what he found [10], they showed that addition of organic fertilizers increases fruits characteristics of "Sakkoty" date palm trees. Also, these results are consistent with what he found [11 and 12], they showed different pollens sources, had a significant effect on fruit set and fruit yield in date palm trees.…”

“…[9] Mentioned that seaweeds extracts and humic acid spray with caused a significant increase in leaves nitrogen, phosphor and potassium compared to unsprayed transplants from his study on Qalib Al-thor mango cultivars. [10] found that organic manure singly or combined with mineral-N and biofertilizers caused significant increases in fruit set and bunch weight for "Sakkoty" date palm trees. Numerous research results conducted in various date palm and date production regions in world indicated that there is a clear effect of source of pollen on percentage of fruit setting, as some researchers found that there are no clear differences in percentage of fruit setting for a specific variety of female date palm as a result of using pollen from different male varieties, while the results of other research indicated that there are clear and statistically significant differences in percentage of fruit setting according to different source of pollen used in pollination.…”

The experiment was conducted in 2022 in one of the date palm orchards of Barhi cultivar cultivated at Dawar palm station, Ministry of Agriculture / Horticultural Department, to study the effects of pollinator cultivar and decomposed organic fertilizer on yield and leaf mineral content of 54 drip-irrigated 7-year-old cultivar dates. A disease- and insect-free palm tree of consistent height and age, Factors of the study included adding two pollinator cultivars, Ghanaami Akhdar (P1) and local cultivar (P2), three times (N1), two (2 days after first pollination) (N2), and three times (3 days after first and 3 days after second) (N3). Decomposed organic fertilizer (sheep manure) was added in three levels (0, 20, and 40 kg.date-1), denoted by M0, M1, and M2. The factorial experiment in an RCBD employed 54 trees since treatments were reproduced three times (one date palm tree per experimental unit). The experimental results revealed that local cultivar pollinator (P2) enhanced fruit dry weight by 77.71% but did not affect leaf nitrogen, phosphor content, or fruit weight. Results revealed that pollination number did not substantially affect leaf nitrogen or phosphor content, but once (N1) showed considerable superiority in fruit dry weight of 78.10 % and fruit weight of 104.14 g. At 40 kg sheep dung, leaf nitrogen and phosphor increased considerably.date-1 (M2) had the maximum leaf nitrogen and phosphor content of 1.548% and 0.380 %, and fruit weight of 107.00 g. M1 had the highest fruit dry weight percentage of 78.95%. Triple interactions between study parameters strongly influenced all attributes.

“…Specifically, the fruits treated with Eucalyptus and Clove oils showed a decrease in the percentage of soluble solids content, while the highest values were recorded in the control treatment in both seasons. These results are consistent with those obtained by Amin (2016); El-Shemy (2020) and El-Salhy et al (2020). Similar responses were reported by Saleh et al (2019), who found that essential oils preserved the total soluble solids content.…”

“…Eucalyptus oil and Clove oil coating guava fruits, in particular, recorded the highest values of firmness compared to other oil treatments in both seasons. Similar results were obtained by Amin (2016); Sebastian et al (2018) and El-Salhy et al (2020). In this study, all tested oils significantly contributed to maintaining the highest fruit firmness of winter guava fruits during the 24-day storage period compared to untreated fruits, with the highest firmness observed in fruits coated with Eucalyptus oil.…”

“…The data from this experiment showed that Eucalyptus oil and Clove oil at 1000 ppm were more effective in in slowing down the ripening process during the storage period. These findings are supported by El-Salhy et al (2020), who revealed that postharvest application of essential oils delayed ripening by reducing total soluble solids % and total sugars % compared to the control. Also, Singh et al (2017) and Sebastian et al (2018) showed that guava fruits coated by dipping in essential oils such as Eucalyptus oil, neem oil, and coconut oil tended to delay fruit ripening, as evidenced by the lowest TSS% and the highest acidity% in the juice.…”

Essential oils have antioxidant and antimicrobial properties, so it is considered one of the most suitable methods to maintain overall fruit quality, reduce decay and extend the shelf life of fruit during storage. Therefore, two experiments using fruits harvested from 14-year-old guava trees in a private farm located in Al-Busayli village, Rashied, Bohaira governorate, Egypt, during the 2021and 2022 seasons. The primary objective was to evaluate the influence of essential oils on the overall quality and extension of the shelf-life of winter guava fruit. The fruits were subjected to various treatments, including dipping in the following solutions (at 1000 ppm) for 5 minutes: control (distilled water), clove oil, eucalyptus oil, mustard oil, and jojoba oil. Subsequently, the coated fruits with essential oils were preserved in cold room with a temperature of 7±1°C and a relative humidity of 90 -95 % for a duration of 24 days. The obtained data revealed that immersing in essential oils of winter guava fruits at concentration of 1000 ppm significantly reduced loss in weight of fruit, rot and respiration rate in addition its also improved fruit firmness. SSC%, acidity, SSC/acid ratio and ascorbic acid content compared to control treatment during cold storage. Moreover, the results show a significant reduction in loss of weight, decay, and respiration rate of guava fruits when Eucalyptus and clove oils were utilized. Furthermore, the applications of Eucalyptus and clove oils demonstrated effectiveness in keeping firmness, acidity, vitamin C content, SSC%, and SSC/acid ratio in guava fruits during the storage. In conclusion, Eucalyptus oil and cloves oil proved to be highly effective in reduce weight loss, decay, and respiration rates while concurrently maintaining the overall quality of winter guava fruits under cold storage conditions for a duration of 24 days, in comparison to the other treatments.

Penicillium digitatum Sacc is a common postharvest pathogen affecting lime fruits. It causes significant losses in postharvest lime production. An emerging alternative to chemical control is the use of environmentally friendly such as edible and biodegradable films and packaging. The goal of the current study was to test different concentrations of Aloe vera gel (5, 15, 25, 50, 75, and 100% v/v), tea tree oil coating (0.5, 1, 2.5, 5, and 10% v/v), and their combination for controlling P. digitatum in vitro. The results revealed that specific concentrations of Aloe vera gel (75% and 100% v/v), tea tree oil (2.5, 5, and 10% v/v), and Aloe vera gel (25%) + tea tree oil (1%) v/v showed the highest inhibitory effect against the pathogen. The most effective concentrations of Aloe vera gel (75%), tea tree oil (2.5%), and Aloe vera gel (25%) + tea tree oil (1%) were evaluated against the green mold disease of lime under natural infection through storage period (0, 7, 14, 28 days). Compared to the control group, all edible layers demonstrated a significant delay and reduced in disease severity percentage throughout the storage periods. However, coating lime fruits with a combination of Aloe vera gel (25%) + tea tree oil (1%) successfully prevented the green mold disease of lime fruits over 28 days. The impact of these coatings was evaluated on lime fruit quality maintenance (weight loss, firmness, juice weight, total soluble solids, total acidity, pH, vitamin C, lipid peroxidation content, total phenols, total flavonoid, and total protein) over 28 days of storage during the 2021 and 2022 seasons. All treatments improved fruit quality through the storage period compared with untreated fruits. Treated lime fruits with Aloe vera gel (25%) + tea tree oil (1%) exhibited slight reductions in weight loss and juice weight compared to alternative treatments as an average of the two successive seasons. Simultaneously, this treatment improved fruit firmness, vitamin C levels, total phenols, total flavonoid, and total protein when contrasted with other treatments as an average of the two studied seasons. These findings show that the combination of Aloe vera gel and tea tree oil coatings enhances the shelf life and maintains the quality of lime fruits. They can also be used as an environmentally acceptable, chemical-free alternative treatment to preserve the postharvest quality of lime fruit.
