This study was carried out at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt, to study the effect of GA3, calcium chloride and vapor guard spraying on fruiting of Manfalouty pomegranate during 2014 and 2015 seasons. The experiment was set up in a complete randomized block design with three replicates, one tree per each. GA3, calcium chloride and vapor guard spraying significantly increased the yield/tree compared to unsprayed ones. GA3 spraying gave the highest yield followed by calcium chloride. On the other hand, all treatments significantly decreased the fruit cracking percentage compared to unsprayed ones. The least fruit cracking was recorded due to calcium chloride spraying. All treatments significantly increased fruit weight and fruit dimensions as well as aril percentage and juice contents compared to unsprayed ones. Moreover, calcium chloride and vapor guard significantly improved the fruit chemical constituents, whereas, GA3 spraying decreased the chemical fruit constituents compared to unsprayed ones. It could be concluded that spraying Manfalouty pomegranate trees with calcium chloride at 40 or 80 ml/L at 1 st July was necessary to get high yield, reduce the fruit cracking percentage and improve fruit quality

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 dryyeast, 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.

The present investigation was carried out during 2013, 2014 and 2015 seasons to study the effect of plant extracts on growth and fruiting of Flame Seedless grapevines. The experiment was arranged in a randomized complete block design in which the study involved seven treatments with three replications, two vines each .Pruning wood weight, leaf area and leaf chlorophyll were significantly increased by spraying either garlic, turmeric or roselle extracts compared to unsprayed ones. Spraying garlic, turmeric or roselle extracts were very effective in improvement the yield/vine and cluster traits. Moreover, these treatments significantly improved the berry quality in terms of increasing the berry weight, total soluble solids and anthocyanin in skin of berries compared to unsprayed ones .The best results were obtained on the vines that sprayed with 0.2% turmeric extract .No significant differences were obtained among the tested extract. It could be concluded that spraying turmeric,  roselle  or garlic extract at 0.1% three times annually was necessary to get high yield with good cluster and berry quality of Flame Seedless grapevines.

This experiment was carried out during two seasons of 2018 and 2019 on 25 years old grapevines of Ruby Seedless cultivar. Head training system was applied byleaving 36 buds per vine (18 fruiting spurs x 2 buds). Eight treatments of GA₃ and jasmine oil as a single treatment or combined were evaluated. The experiment aimed to examine the effect of GA₃ and jasmine oil on improving yield and berry quality of Ruby Seedless grape cultivar.The studied treatments increased the yield, cluster and berry weight. The best treatment in this term was spraying with GA₃ at 20 ppm when berry size about 3 mm plus jasmine oil at 1.5 cm³/liter at the beginning of the veraison stage while the control vines gave the lowest values among all treatments.Jasmine oil as a single treatment was the best treatment in respect of TSS%, acidity, TSS/TA ratio and reducing sugars among all treatments.This study concluded that the beneficial effects of spraying jasmine oil at veraison stage as single or in combined with GA₃ at 20 ppm when berry size about 3 mm to increase yield, berry and cluster weight and improving berry quality of Ruby Seedless grape cultivar.

One of the major physiological disorders for pomegranate cultivation is theexcessive of fruit cracking. lately, a pomegranate physiological syndrome called ‘aril paleness’ in which apart or all of the arils appear discoloration, affect the quality of fruit and such fruits are not desired forconsumer. The present research designed to evaluate the effects ofmethyl jasmonate (MJ), humic acid (HA) and potassium (K) on reducing these disorders and improving fruit quality. Seven treatments including MJ (5 and 10 ppm), HA (50 and 100 ppm), Liquid K (1 and 2%) and control, were tested on pomegranate trees spraying three times, at the beginning of flowering (during April), after full bloom (end of June) and before harvesting (mid-September), during the two seasons of study. Different parameters including yield, fruit cracking and fruit quality were measured. The obtained results indicated that spraying HA at 100 ppm and MJ at 10 ppm are considered the best in their effects on the yield components, fruit quality and anthocyanin content, however for decreasing the fruit cracking, it could be recommended to spray the fruits with K at 1% or MJ 10 ppm compared to the rest of the treatments.

Kishk is a natural functional food as minor constituents that are deficient in milk are supplemented by cereals. It also widely consumed in the diet of many people in the Middle East, especially Upper Egypt. This work was conducted at Dairy Department laboratories, Faculty of Agriculture, New Valley University as well as laboratories of Agricultural Research Center, Giza, Egypt. The aim of this paper is to investigate replacing bulgur by different percent of broken faba bean seeds (by-product) and type of milk on compositional, nutritional, microbiological, and sensory qualities of Saidy kishk to increase the added value viewpoint of economical and nutritional. The results indicated that there were a significant differences in physiochemical properties, i.e. moisture, ash, protein, fat, carbohydrates contents, pH and titratable acidity, essential amino acids, mineral contents such as Ca, Mg, K, Na, P and Fe, microbiological properties, TBC and LABC as well as sensory properties of Saidy Kishk samples as a result of replacing bulgur by different percent of broken faba bean seeds by 25 and 50% or change the studied milk type, i.e. full cow milk, skimmed milk or Laban zeer. This study concluded that Saidy Kishk samples manufactured from 50% B+50% Fb with skimmed milk had the highest values of threonine (3.75%), leucine (10.91%), lysine (6.47%), phenylalanine (5.33%), valine (4.88%), histidine (3.11%), Ca (319.67mg), Mg (172.00mg), K (1117.67mg/100g DWB) and Fe (7.19 ppm). Therefore, it is suggested that this formula of Saidy Kishk samples could be used to increase the added value viewpoint of economical and nutritional.

The effects of microwave (MW) treatments for 30 and 90 s or cold plasma (CP) treatments for 2, 6, and 10 min on structural, physicochemical, and digestive properties of rice starch were investigated and compared with the effects of combined MW and CP treatments. Dual modification of starch using combined MW and CP treatments significantly changed starch granules' morphology, and starch showed lower crystallinity, swelling power, and peak viscosity than rice starch with a single modification. However, no significant changes were found in rice starch's crystalline structure and FT-IR spectra pattern after single or combined treatments. Effects of these treatments on the amylopectin branch chain length distribution and molecular weight of rice starch varied considerably depending on treatment type and treatment duration. Moreover, the dually modified rice starch contained more great content of resistant starch. Thus, the synergistic effects between MW and CP had more profound modification than the single treatment. Also, the dual treatment can be used to produce modified starch for industrial applications.
