This study was processed at the experimental orchards, Agriculture of Faculty, Assiut University, Egypt, to survey impact of nitrogen fertilizers at different sources on Manfalouty pomegranate trees growth, yield and fruit quality in 2020 and 2021seasons. The research design was randomized complete block of eight treatments with three replications. The results findings as follow Amending the advised of nitrogen dosage as twice (mineral-N plus organic or bio-form) or three sources of nitrogen fertilization were used: mineral-N, organic-N and bio-N form (mineral plus organic and bio-form) materially raised the shoot length, leaf surface, chlorophyll, leaf content of N, P and K comparing to mineral-N source only (control). All amending treatments materially raised the yield/tree, commercial fruit % and materially reduced the percentage of fruit cracking and sunburn comparable to use control. Amending with any triple form (organic + bio + mineral) materically amended the fruit traits due to raising the fruit weight, arils percentage, soluble solid contents, sugar and contents of anthocyanin and vitamin C and reducing the acidity and tannins contents comparing to use control treatment. It is obvious from the obtained data that the interest of organic and bio manures for pomegranates forms, where this is desired to amend the trees growth and nutritional status and production quality and then the package yield. Moreover, these amending reduce the production cost and ecological contamination. [ABSTRACT FROM AUTHOR]

This study was conducted at a special farm existing at Banu Aday, Manfalout city, Assiut Governorate, Egypt, to study the impact of soil conditioners on growth and fruiting of Manfalouty pomegranate trees during 2020 and 2021 seasons. Hundz soil, bentonite and compost were applied in January of each season. This study designed as a randomized complete block system with four transactions and three replicating’s two trees for each. Data indicated that using hundz soil, bentonite or compost considerably raised the shoot length, leaf area, chlorophyll, relative water contents, leaf-N, P and K%. However, all treatments considerably reduced the leaf proline content. All soil conditioners used considerably increased the yield/tree and commercial fruit % and considerably reduced the percentages of fruit splitting and sunburn compared to use check treatment. Moreover, all treatments used caused a significant improvement the fruit traits represented by increasing weight, arils percentage of fruits, total soluble contents as well as reducing sugar, vitamin C and anthocyanin contents and lack the total acidity in comparison with control. Using hundz soil and compost as soil conditioners recorded the highest units of general evaluation these values were 99.6 and 97.2, respectively. In general view, obtained results ensure the importance of using soil conditioners i.e., hundz soil or compost to produce pomegranate trees as improving the characteristics of fruit and thus increasing the marketing value of yield. In addition, these soil conditioners treatment used lead to soil improvement, growth and increase production yield, then reduce production cost. [ABSTRACT FROM AUTHOR]

Two plums cultivars (Red 'Centerose' and Yellow 'Yabany Zahaby’) were used to produce juice. Several treatments were conducted on plums before juice extraction, including freezing, enzymatic hydrolysis (pectinase), microwave, and steaming (hot water vapor). The obtained plums juices were analyzed for physical and chemical properties. The results showed that addition of 250 mg of pectinase/ 100g plums increased the juice yield to 78.24% and 76.67% for the red and yellow plums, respectively. Also, microwave heating for 20 s and steaming for 60 min enhanced the juice yield for both red and yellow plums. Furthermore, pectinase addition to plums before juice extraction improved nutritional and antioxidant properties of obtained plum juice. Besides, ascorbic acid content in obtained red and yellow plums juices after enzymatic treatment recorded 62.49 and 48.94 mg/ 100 ml, respectively. On the other hand, red and yellow juices obtained after steam treatment had significantly higher values of phenolics, flavonoids and antioxidant activity, when compared to all other treatments. The results indicate that combined freezing treatment with pectinase addition facilitate the production of a nutritious clear juice, which promote its usage for food and beverage applications.

The current investigation was executed at in a private the Orchard, located at El-Badary district, Assiut Governorate, Egypt, to study the effect of organic and bio-form fertilizers on vegetative growth, nutrient status and fruiting of Manfalouty pomegranate trees during 2019 and 2020 seasons. The experiment was arranged in a complete randomized block design with five replications and it consisted of five treatments. The results can be summarized as follow: Using the recommended dose of nitrogen (RND) via thrice form (mineral plus organic and bio-form) significantly increased the shoot length compared to use RND via mineral-N fertilizer (check treatment). All fertilization treatments significantly increased leaf area, chlorophyll and contents of N, P and K in leaves compared to check treatment. The fertilization treatments significantly increased the yield/tree and significantly decreased the fruit splitting and sunburn percentage compared to use mineral-N source only. Fertilization with any twice form (organic plus mineral)or thrice form (organic + bio + mineral) significantly improved the fruit properties by increasing the fruit weight, arils percentage and total soluble solids as well as sugar, anthocyanin and vitamin C contents and decreasing the total acidity compared to using the check treatment. It is clear from the current results the importance of fertilization through organic and bio-form for pomegranates productivity, via improve the fruit quality which reflects on induce the increase packable yield. In addition, such fertilization treatments reduce the cost of production and environmental pollution. [ABSTRACT FROM AUTHOR]

Successful seed production depends on the variety, the environment, and the agricultural practices. Limited information is available on the effects of green podpicking treatments on the production of seeds. Therefore, two-season field experiments were conducted in 2019 and 2020 to study the effects of four green fruit picking treatments (no green fruit picking ‘T1’, first two pickings ‘T2’, first 4 pickings ‘T3’, and first 6 pickings ‘T4’) and six varieties (Pusa Sawani ‘V1’, Emerald ‘V2’, Eskandarany ‘V3’, Baladi Assiut ‘V4’, Beghera Iraqi ‘V5’, and NOKH-1002 “F1 hybrid okra ‘V6’) on okra growth and seed yield and quality. The results of the experiment showed that okra plants of T1, followed by those treated with T2 had higher number of dry pods/plant, weight of pods/plant, and seed weight (kg/feddan), seed vitamin C, and pH in both seasons. Plants of T3 were significantly taller than T1 in both seasons. There were differential responses of the studied varieties to the picking treatments. Plants of ‘Eskandarany’ with no pickings, followed by ‘Emerald’ with two pickings always had higher number of dry pods, weight of pods/plant, and seed weight (kg/feddan). We can conclude that okra plants with no green fruit picking, as compared to two, four, and six fruit pickings, can be the best option for seed production due to the observed higher number of dry pods, weight of pods/plant, seed yield and quality.

Effects of pre-and postharvest treatments with potassium phosphite, potassium phosphate, and salicylic acid against the severity of gray mold disease caused by Botrytis cinerea in strawberry fruits were investigated under ambient conditions. Seven B. cinerea isolates were collected from naturally infected strawberry plants. The treatment with potassium phosphite at concentration of 500 mg/L significantly reduced the fungal growth compared to other treatments in vitro. The treatments with potassium phosphite at concentrations of 250 or 500 mg/L resulted in the highest disease reduction, followed by the treatment with salicylic acid. Additionally, effects of postharvest treatments with these compounds on disease reduction and biochemical attributes of strawberry fruits were evaluated during storage for 9 days at ambient conditions. The highest disease reduction percentage was found with potassium phosphite. Besides, the phenolics content and peroxidase activity of potassium phosphate were found to be greater than those of potassium phosphite or salicylic acid. However, a reduction in the total soluble solids, titratable acids, and ascorbic acid contents of fruits was found for all treatment groups at the end of storage period. Based on the obtained results, potassium phosphite and salicylic acid can be recommended as fungicide alternatives for extending postharvest shelf life of strawberry fruits. [ABSTRACT FROM AUTHOR]

This study was conducted during two successive seasons of 2018 and 2019 on Balady Mandarin trees, 20 years old budded on sour orange rootstock and planted at 5×5m apart. Grown at the productive farm located at Shandawel Island, Sohag governorate. This experiment aimed to study the effect of active dry yeast, ascorbic acid, vitamin B complex and their combination on yield components, alternate bearing and fruit quality of Balady Mandarin cultivar grown under Sohage conditions. The obtained results showed that using of active dry yeast at 10g/l (as soil application) as single application or in combination with ascorbic acid and vitamin B complex at 1g/l from each (foliar application) caused a pronounced increasing of fruit numbers, fruit weight (g) and yield (kg). The later also improved fruit quality in terms of TSS%, TSS/acid ratio as well as total sugars, vitamin C content and reducing total acidity of Balady Mandarin fruits. According to results of the current study it could be concluded that using active dry yeast at 10g/l (as soil application) as single treatment or in combination with spraying ascorbic acid (1g/l) plus vitamin B complex (1g/l) three times on the first week of May, July and September led to improve both yield and fruit quality of Balady Mandarin Cultivar under Sohage environmental conditions.

In the present investigation, effect of calcium chloride (CaCl2) used as foliar application (0, 10, 20 mM) was studied on morphological, yield, and quality of lettuce (Romaine and Green Waves cultivars) during 2017/2018 and 2018/2019 seasons. Our results indicated that, foliar spray of calcium chloride either at 10 or 20 mM significantly increased vegetative growth and yield parameters i.e., leaf number per plant, fresh and dry leaf weight compared to control treatment. Also, foliar spray of calcium chloride resulted in a significant increase in yield and quality parameters i.e., TSS, chlorophyll content and Vitamin C. 'Romaine' cultivar was significantly superior to 'Green Waves' cvs in plant height, fresh and dry weight of the leaves, TSS and chlorophyll content. However, there was no significant difference in vitamin C content between the two tested cultivars. 'Green waves' cv. sprayed with 20 mM CaCl2 gave the highest significant leaf number per plant. Fresh and dry leaf weight of 'Romaine'cv recorded the highest values when the plants were sprayed with 20 mM CaCl2 in both seasons., In the first season, 'Romaine'cv sprayed with 20 mM of CaCl2 produced the highest total yield, while the highest total yield in the second season was obtained from plants of both tested cvs sprayed with 20 mM CaCl2. 'Romaine' cultivar treated with 20 mM of calcium chloride as foliar application had the highest TSS and chlorophyll content. Fascinatingly, high association existed between total yield and all studied traits, except leaf number per plant. Overall results suggest applying calcium chloride as foliar application at 20 mM for improving yield quantity and quality in both 'Romaine' and 'Green Waves' cultivars. [ABSTRACT FROM AUTHOR]

The use of organic vermicompost fertilizers is considered one of the promising fertilizer. Therefore, the experiment aimed to study the effect of using liquid vermicompost fertilizer as an alternative to chemical fertilizers in the production of lettuce, Crisp head variety. In this study, a field experiment was conducted during the two winter seasons of 2019-2020 and 2020-2021 at the Agricultural Research Station in the Abies region, affiliated to the Faculty of Agriculture, Alexandria University Egypt. This experiment aimed to evaluate the response of lettuce plants to the application of liquid vermicompost (LVC) fertilizer through four different concentrations (2.5%, 5%, 10%, and 20%), and the chemical fertilization treatment (100% NPK) in the recommended rate as a control treatment for lettuce production, on some vegetative growth characters; Fresh weight plant-1 (kg), head net weight plant-1 (kg), total yield fed-1 (ton), and unmarketable yield fed-1 (ton), in addition to some biochemical characteristics; vitamin C, dry matter, total soluble solids, and carbohydrates as well as estimate the element content and quality elements, such as nitrogen (N+ ), potassium (K+ ), phosphorus (P+ ), calcium (Ca2+ ), magnesium (Mg2+ ), and iron (Fe2+ ). The results showed a gradual significant increasing in the values of most of the studied traits by increasing the concentrations of vermicompost fertilizer from 2.5 % to 20%. The application of vermicompost treatment with a concentration of 20% LVC gave the highest significant values for most of the studied traits without a clear significant difference compared to the chemical fertilizer 100% NPK.

A field trial was carried out during 2018/2019 and 2019/2020 seasons at the Experimental Farm of Faculty of Agriculture, Assiut University to study the effect of foliar humic acid application at the concentrations of 0 (control), 200 and 400 ppm three times, monthly interval on growth, fruit yield, and essential oil yield and its composition of caraway (Carum carvi L.) plant. The results indicated that humic acid treatments improved the vegetative growth characteristics (plant height, branch number per plant and plant dry weight), fruit measurements (umbel number, 1000-seed weight and seed yield) and essential oil parameters (oil percentage, oil yield and oil constituents) in comparison with control plant (without humic acid). However, a rate of 400 ppm was more effective than the level of 200 ppm in this regard. Seeds of plants received 400 ppm showed the highest contents of total proein, total carbohydrates, total phenolics, ascorbic acid (vitamin C) and thiamine (vitamin B1). In contrast, these seeds contained the lowest levels of nitrate and nitrite. These findings were closely correlated with increasing 1000-seed weight showing better quality. Chemical analysis of caraway leaves cleared that the maximum contents of nitrogen, phosphorus, potassium, and pigment were occurred by humic acid at 400 ppm resulting in significant increases compared to 200 ppm level in most cases. It was found a positive relationship between the highest contents of leaf N, P and K and the improvement of vegetative growth and fruit characteristics, consequently increase of seed production.

A field experiment was carried out during the two successive winter seasons of 2017/18 and 2018/19. The aims of the experiment were to investigate the effect of using three different mulch treatments (black polyethylene, clear polyethylene, and bare soil) on strawberry ‘Florida’ and ‘Winterstar’ cultivars (Fragaria X ananassa Duch) regarding the fruit yield, yield attributes, and some fruit quality characteristics (vitamin C, anthocyanin, acidity, TSS, and TSS: acidity), along with the financial aspects of using polyethylene mulching for strawberry productivity. Compared to the un-mulched plants, the total fruit yield of ‘Florida’ and ‘Winterstar’ plants was increased by ~40-49% and 17-18%, respectively in the black plastic mulching in the two years. Clear plastic mulching was accompanied by an increased total yield of ‘Florida’ by 19-34%, while decreased ‘Winterstar’ fruit yield by 14-24%. Regarding vitamin C content, the main effects of mulching treatment showed that plants grown in black plastic mulching had significantly higher vitamin C content than clear plastic (both seasons) or no mulching (second season). ‘Florida’ plants in the black plastic mulching achieved significantly the highest vitamin C levels compared to the other treatments. Similarly, ‘Florida’ plants in the black plastic mulching had higher TSS content than the other mulching treatments. Depending on the cultivar used and the growing season, plastic mulching (whether clear or black) was beneficial in improving the fruits anthocyanin content compared to the un-mulched plants. In conclusion, plastic mulching (especially the black) was helpful in improving fruits contents of vitamin C and anthocyanin compared to the un-mulched plants. Regarding the financial aspect, using black plastic mulching for strawberry production in Assiut governorate was more profitable than the un-mulched farm. [ABSTRACT FROM AUTHOR]

This study was carried out during two successive seasons of 2017 and 2018 to evaluate some pomegranate cultivars grown at Assiut Governorate, Egypt. Three local Egyptian pomegranate (Punica granatum L.) cultivars, namely Assiuty, Assiuty-1 and Nab-Elgamal compared to Manfalouty cv. which is one of the commercial cultivars in Egypt. Vegetative growth’ traits, yield components and fruit quality as well as numerical evaluation were investigated. Growth traits were determined (shoot and leaf traits) and yield components (fruit set percentage, yield/tree (kg) and fruit cracking percentage) as well as physical fruit traits (weight, dimension, grains percentage and juice percentage). The chemical traits such as total soluble solids, titratable acidity, reducing sugars as well as vitamin C and anthocyanin contents were assessed. The obtained results indicated that there is a wide variation in each of these traits among the studied cultivars. Assiuty-1 cultivar had the highest values of most studied traits compared to the other studied cultivars, respectively. On other hand, the least values of these traits were recorded of Nab-Elgamal cultivar. As the numerical evaluation of these studied cultivars, it could be arranged in a descendingly order as follows: Manfalouty, Assiuty, Assiuty-1 and Nab-El-gamal cultivar. The inter simple sequence repeats (ISSR) marker was used to assess the genetic relationship among the pomegranate cultivars. UPGMA-cluster analysis discriminated the four tested cultivars based on data of ISSR at 0.76 similarity. Assiuty and Assiuty-1 cultivars showed the highest value of similarity (0.87) on the dendrogram, both cultivars showed a good relationship with Nab Elgamal cultivar by showing an average value of similarity (0.82). While, Manfalouty cultivar showed low similarity (0.76) with the rest of cultivars and was separated in a single branch on the dendrogram. This grouping showed a clear genetic relationship among the tested cultivars, which could be used in breeding and improvement programs of pomegranate. These results revealed that Assiuty and Assiuty-1 are considered promising cultivars to obtain a high yield with good fruit quality compared to Nab-El- Gamal. [ABSTRACT FROM AUTHOR]

This study was conducted during two successive seasons (2016/2017 first ratoon and 2017/2018 second ratoon) of Williams banana plants. The plants grown in a private banana orchard, where clay loam soil under flood irrigation system, at 3.5x3.5m apart located at Nakada district, Quena Governorate, Egypt. Forty eight stools each containing three plants were chosen to evaluate the effect of yeast applied as soil drench and spraying ascorbic acid (V.C) on growth, yield and fruit quality. These treatments were arranged in a randomized complete block design in split plot arrangement with three replicates. The obtained results could be summarized as follows. Ascorbic acid spraying significantly increased the length and circumference of pseudostem, leaf area and total leaf area/plant as well as percentage of N, P and K of leaves compared to unsprayed ones. Also, these treatments significantly increased the yield components and improved the fruit quality compared to unsprayed ones. Yeast application was very effective in enhancing all growth aspects, yield and fruit characteristics compared to untreated ones. All combinations of ascorbic acid spraying on the yeast treated plants resulted in a significant increament in all growth aspects, yield components and fruit quality as compared to check treatments. The best results regarding the growth and fruiting were obtained with ascorbic acid spraying (at 200 ppm) accompanied with yeast application (at 40 g/plant) compared to other tested treatments. It is evident from the foregoing results that the application yeast at 40 g/plant and ascorbic acid at 200 ppm application four times during growth season (April, June, August & October), singly or in combination improved the growth and yield of Williams banana plants.

The present work was conducted during the two successive seasons of 2012/2013 and 2013/2014 to determine the effect of organic fertilization, foliar spray with ascorbic acid and salicylic acid as well as their interactions on growth, yield and oil production of fennel. Organic fertilizer was plant compost at 0, 8, 16 and 24 m3/fed. The plants were sprayed with ascorbic acid and salicylic acid each at 0, 50, 100 and 200 ppm. The revealed results indicated that utilizing organic manure increased herb dry weight/plant, number of umbels/plant, fruit yield/plant and yield/fed. Volatile oil % and volatile oil yield/plant and per fed. The highest values of such parameters were obtained by adding compost at the high level (24 m3/fed.). In most cases, spraying fennel plants with ascorbic acid or salicylic acid improved plant growth, fruit yield and oil production. Foliar spray with ascorbic acid at 100 ppm gave the maximum values of herb dry weight, fruit yield and volatile oil yield. The highest values of umbel number/ plant were occurred by using ascorbic acid at 200 ppm in the first season and salicylic acid at 100 ppm in the second one. The application of ascorbic acid at 200 ppm registered the maximum values of volatile oil %. With regard to the interaction, the most of combined treatments showed a significant increase in all examined characters. The addition of compost at the high level (24 m3/fed.) plus 100 ppm ascorbic acid gave the highest values of herb dry weight, number of umbels/plant, fruit yield and volatile oil yield. While, the use of compost at the high level in combination with 200 ppm ascorbic acid recorded the maximum values of volatile oil %. From the obtained results, it could be recommended, to supply fennel plants with plant compost at 24 m3/fed in combination with foliar spray with ascorbic acid at 100 ppm to obtain better growth, high yield of fruit and volatile oil under this investigation conditions.

This study was conducted during two successive seasons 2014 & 2015 to investigate the effect of coating and wrapping materials on storability and quality of Balady mandarin fruits during the storage period. Fruits were coated with salicylic acid, paraffin oil or camphor oil, as well as wrapped with foil paper and untreated. The fruits were stored either at room temperature or cold conditions (0+2°C) + humidity of 90+5%. The results showed that the fruit weight loss %, fruit decay %, total soluble solids % and TSS/acid ratio were significantly increased with prolonging the storage period. On the other hand, the advanced storage period induced a gradual decrease of fruit juice percentage acidity %, vitamin C and total phenolic contents levels. All treatments caused decreased fruit weight loss and fruit decay percentage under both storage conditions. Using foil paper wrapping or salicylic acid gave the least fruit weight loss and decayed fruit percentage, respectively. The most loss reduction was associated with the cold storage than room temperature conditions. Also, all treatments improved the fruit quality during the storage period compared to the untreated ones. So, it could be concluded that oil coating or wrapping maintained fruit freshness without negative effects on fruit quality parameters. Meanwhile, coating and wrapping fruits retained high levels of juice volume, acidity, ascorbic acid (V. C) and total phenolic contents as well as lower total soluble solids and TSS/acid ratio loss than controls during storage. Such treatments can be used as alternative of chemical application in order to maintain human health and environment. [ABSTRACT FROM AUTHOR]

This investigation was conducted during two seasons of 2012 and 2013 to study the effect of some post- harvest treatments on storability and quality of Manfalouty pomegranate fruits during storage at ambient temperature. The storage treatments are Nigalla sativa coating oil or wrapping singly or in combination. Sample of each treatments were randomly taken weekly. The obtained data illustrated that undesirable fruits percentage and fruit weight loss %, increased by extending room temperature storage period till 7 weeks. The most clear reduction was associated with untreated fruits where the less values were related with fruit oil coating or fungicidal tissue paper wrappeing singly or in combination. While, juice volume per 100 gm arils gradually decreased by extending room temperature storage period. Generally, all treatments of oil coating or any of wrapping materials singly or in combination of oil +fungicidal treated tissue paper wrapping, Nigella sativa essential oil, Nigella sativa essential oil coating + perforated polyethylene wrapping, fungicidal treated tissue paper wrapping and perforated significantly reduced the undesirable fruit and fruit weight loss percentage and significantly increased the juice volume contents compared the untreated fruits during room temperature storage for seven weeks. Its clear to notice that prolonging room temperature storage for 7 weeks caused an increase of total soluble solids % and TSS/acid ratio. While Titratable acidity and vitamin C contents in stored fruits were reduced. Moreover, all treatments significantly decreased the TSS, acidity and increased the TSS/acid ratio and vitamin C content compared to untreated ones. So, it could be concluded that it is important to use Nigella sativa essential oil coating and polyolephinic heat-shrinkable film wrapping to extend the storage life of pomegranate fruits and kept the original quality of the freshly harvested of Manfaluty pomegranate fruits.
