It can impair the growth and production performance of olives. Many investigations recommended spraying Lithovit to reduce the effect of water stress. We believe that we have designed an innovative solution to follow up the effect of spraying Lithovit (Ca CO3 & Mg CO3) on olive trees which exposure to different irrigation levels. Four concentrations of Lithovit were sprayed on olive (Olea europaea var. Manzanello) trees (0, 2, 4 and 6 g/L) under three irrigation levels (50, 75 and 100% of evapotranspiration for crop “ETc”) during 2017, 2018 seasons. Strong evidence of irrigation at 75% of ETc was found on olive growth, blooming and fruit setting. It was the best irrigation level to balance between vegetative growth and blooming. Moreover, there were significant variations between spraying Lithovit at 2 g/L and other concentrations on Blooming and fruit setting. Furthermore, the interaction between spraying Lithovit and irrigation levels cleared that spraying Lithovit at 2g/L and irrigation at 75% of ETc enhanced blooming and fruit setting. On the other hand irrigation at 100% of ETc with spraying Lithovit at 2g/L improved the vegetative characteristics.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124847396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This solution is now widely used by the vegan community and egg allergens as an egg replacer. The objective of this study was to evaluate the quality and possibility of egg white substitute with aquafaba in sponge cake. Physical characteristics, chemical composition and sensory properties of the cake samples were evaluated. The results demonstrated that foaming capacity values of aquafaba were 389.33% and egg white was 582.66%. Foam stability values were 85.49 % and 92.28 % in aquafaba and egg white, respectively. Water and oil absorption capacity of the aquafaba and egg white were 2.66 g/g 1.32 g/g, 2.94 g/g and 1.99g/g, respectively. The replacing of egg white by aquafaba did not greatly affect physicochemical parameters of the sponge cake made by using egg white. The cake made with aquafaba was slightly less moist than cake made with egg white (21.67%and 22.79%), had less height (4.21 and 4.47 cm), lower volume index (11.25 and 11.65 cm) and lower pH (7.95 and 8.02). Baking weight loss in aquafaba cake is 11.47% higher than egg white cake 9.09%. Sensory evaluation of aquafaba cake samples showed an acceptance and no negative effects in overall properties. The texture profile analysis of cakes prepared with aquafaba showed less hardness. The mineral composition (Zn, Cu, Mn, Ca, Fe, Mg and P) showed a high amount in aquafaba compared with egg white cake therefor, it could be is concluded that aquafaba is beneficial when instead of with egg white in eggless cake recipes.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127277550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results cleared that, the tested fertilizers were influenced target parameters of N. sativa plants significantly.

The results of pests infested N. sativa plants revealed highly significant differences (P ≤ 0.01) between its mean numbers due to variation in rates and types of fertilizers.

Also, the mean numbers of inspected pests were correlated significantly with plant height and branches number.

The main results could be summarized as follows: Misr-1 cultivar exceed Sids-1 cultivar in grain yield and its components significantly except grain yield (ton/fed.) and harvest index%. Addition of 75kg N/feddan (ammonia gas 82%) resulted in a significant increment in yield and its components except harvest index% comparison with other treatments (control and 50 kg N/ feddan). The application of organic fertilizer at the rate of 15 ton/ feddan significantly increased yield and its components, except harvest index%.
