Chia seeds have good nutritional and pharmaceutical properties, thus, fortification with chia seeds in toast bread could be beneficial in improving the final product. This study was carried out to examine the effect of partial substitution of wheat flour (WF) with defatted chia seed flour (DCSF) at levels of 5, 10, 15 and 20%. The rheology characteristics of dough, proximate compositions, and physical characteristics of the toast bread. Partial substitution of WF with DCSF significantly (P≤0.05) increased water absorption, arrival time, dough developing time and stability of dough. Meanwhile, the softening degree was reduced in all blends containing DCSF. Also, elasticity and energy were increased by the addition of DCSF. Toast bread supplemented with DCSF reduced the quality in terms of specific loaf volume, while weight was increased. DCSF up to 20% could partially replace WF in toast bread as it increases its nutritional value in terms of fiber, amino acids content and minerals with only a small depreciation in the bread quality. Sensory characteristics showed that toast bread incorporation of DCSF up to 20% was acceptable and gave a significant difference (P≤0.05) in parameters of taste","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82242786","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}

Modulations of gut microbiota and lowering the risk of metabolic syndrome by probiotics have taken a great attention in research. Survival of probiotics in different dairy products illustrates a struggle for these microorganisms, especially during the cold storage of these products. Cheddar cheese and ice cream are a good carrier for different probiotic species. Microencapsulation or adding prebiotics are the main strategies for enhancing the viability of different probiotic species during the cold storage of dairy products. Application of red laser technology could also enhance production of organic acids and flavor compounds of L. casei during the cold storage of Labneh.

Four bread wheat cultivars (Giza 171, Shandaweel 1, Sids 14 and Sakha 95) were studied under 100 %, 60 % and 40 % of full irrigation in calcareous soil conditions. Three irrigation treatments were distributed in the horizontal strips, and the four bread wheat cultivars were distributed in vertical strip. Results showed that full irrigation (100%) which used 2476 and 2357 m 3 /fed in the in the first and second season, produced the highest values of all studied traits, followed by irrigation treatment 60% then irrigation with 40% of full irrigation. Data cleared the superiority of Sakha 95 in grain, biological yield and harvest index percentage. Moreover, Sakha 95 was the best cultivar under all irrigation treatments. On the other hand, the worst cultivar was Sids 14 for grain and biological yield. Genotype by environment interaction (GGE) Biplot analysis revealed that Shandaweel 1 was the most stable cultivar regardless of its grain yield. Meanwhile, Sakha 95 was the most superiority cultivar with moderate tolerance to reduced irrigation. On the contrary, Sids 14 had reasonable stability and was the worst cultivar for grain yield. Moreover, Giza 171 was the most unstable cultivar under these conditions. Irrigation water productivity (IWP) values increased with increasing water deficit for all wheat cultivars. The highest IWP values were 2.90 and 3.10 kg/m 3 in first and second season by using water stress treatment 40% from full irrigation with Sakha 95, respectively. While, the lowest values were 1.14 and 1.41 kg/m 3 were obtained from Sids 14 with 100% irrigation treatment in the first and second season, respectively.

The results showed that ‘Kishu’ has the highest viability in comparison with other cultivars. Both ‘Fedela’ with ‘Kishu’, ‘Spinosa’ and ‘Sunburst’ had the maximum initial fruit set. The highest percentages of retained fruit were registered when pollen of ‘Kishu’ was used to pollinate both ‘Fina’ and ‘Fedela’. When all pollens of tested Mandarin cultivars were used for ‘Spinosa’ Clementine, they did not obtain any retained fruit, and these hybridization combinations revealed the highest percentages of fruit drop. ‘Fedela’ fruits recorded a maximum value of the average number of developed and undeveloped seeds when they were cross-pollinated with ‘Kishu’ and ‘Sunburst’ pollens. Fluorescence microscopy examination showed that ‘Kishuʼ and ʻAvanaʼ as pollen sources had a high level of full cross-compatibility with ‘Fedela’, while ‘Sunburst’ and ‘Willow leafʼ have a high level of partial cross-compatibility with ʻFedelaʼ. ‘Fina’ showed a low degree of partial cross-compatibility, while ‘Spinosa’ showed some degree of cross-incompatibility with all studied pollen sources. It can be concluded that all studied Mandarin cultivars could be promising pollenizers for the self-incompatible ‘Fedela’ Clementine cultivar, thus it is recommended to culture these cultivars together in the same orchard.","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87234324","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}

Economic evaluation of the interaction between sowing methods and weed control methods was also assessed. The application sequences of nine herbicides in six treatments included tribenuron-methyl 75% DF (Aonostar 75 DF) followed by fluazifop-p-butyl, 12.5% EC (Fusilade super 12.5% EC) (T1), tribenuron-methyl, 75% WG (Zinostar 75% WG) followed by (Fusilade super) (T2), bromoxynil octaoate, 24% EC (Brominal 24% EC) followed by clodinafop propargyl 2.5% + pinoxaden 2.5% (Traksos 5% EC) (T3), bromoxynil octanoate, 24% EC (Bromo plus 24% EC) followed by clodinafop propargyl 2.5% + pinoxaden 2.5% (Traksos) (T4), florasulam 7.5% + flumetsulam10% (Derby 17.5% SC) 17.5% SC followed by clethodim 12.5% EC (Select super 12.5% EC) (T5) and dicamba, 48% SL (Dimo up 48% SL) followed by (Select super) (T6). The herbicide treatments were compared to hand weeding (twice) (T7) and unweeded control (T8). The obtained results revealed that seed drilling method increased straw, seed, fiber and oil yield in both seasons, compared to broadcasting method. Herbicide treatments of T5, T6, T1 and T2, T3 and T4 decreased dry weight of dodder and annual weeds 90 days after application, in both seasons, as compared to unweeded control. The result suggested that seed drilling method combined with the herbicidal treatments of T5, T6, T1 and T2 were greatly effective against heavily infestation with dodder and total annual weeds.

However, the rate of self-sufficiency is still low as production is unable to fulfill the growing domestic demand. This is reflected in the low selfsufficiency rate, where the maize crop decreased from 46.1 % in 2017 to 42.6 % in 2019, and the faba bean crop from 30.7 % in 2017 to 10.3 % in 2019. The state resorted to imports to bridge the food gap, which amounted to about 9.4 million tons for the maize crop, 865 thousand tons for the faba bean crop. This research aimed to identify the current situation and the future prospects of maize and faba bean crops, at the national and three desert governorates levels in Egypt in light of climate change. The results of the ARIMA model forecast showed that there was an expected increase in the gap of maize crop, in Egypt, from about 10,958 thousand tons in 2026 to about 12,223 thousand tons in 2030, an increase of about 30.1 % in 2019 and an annual average about 11,590 thousand tons during the period (2026-2030). While, the self-sufficiency of maize in Egypt decreased from about 38.4% in 2026 to about 34.5% in 2030, an estimated decrease of about 9.9% for 2019. The results of the forecast showed that there was an increase in the gap of faba bean crop in Egypt from about 2,495.5 thousand tons in 2026 to about 3,783.4 thousand tons in 2030, an increase of about 337.4 % over 2011. The self-sufficiency of faba bean crop in Egypt was shown to decrease from about 10.9 % in 2026 to about 1.5 % during 2030, by an estimated decrease of about 85.4 % over 2019. The forecast results showed a decrease in the area under cultivation from about 0.06 thousand acres in 2026 to about 0.001 thousand acres in 2030, an estimated 98.9 % decrease from 2018. The forecast results also showed that the area cultivated with faba bean crop in the New Valley Governorate decreased from about 1.22 thousand acres in 2026 to about 0.20 thousand acres in 2030 with an estimated decrease of about 89.1 %. The production decreased from about 1.54 thousand tons in 2026 to about 0.36 thousand tons in 2030, an estimated decrease of about 84.5 % from 2019. In addition, the production of maize in North Sinai Governorate decreased from about 0.07 thousand tons in 2026 to about 0.01 thousand tons in 2030, an estimated 8.3 % decrease from 2019. The forecast of the maize crop production with climate change not taken into consideration, showed a decrease in production of maize crop in North Sinai governorate. While forecasting the production of maize crop with climate change in consideration, the most influential element studied was higher temperature, which was found to increase on average by one degree Celsius during the crop growth season, which resulted in a decrease in production by about 22.6 %.

The research was carried out in Sahl Eltina region, village number 3 that was previously selected to implement the algae project as a model for an integrated farm. The beneficiaries of the project at that farm were selected, where there were 25 respondents (farmers), representing the overall population of the study. The data were collected by personal interviews using a questionnaire, during April 2021. Frequencies, percentage, computational average and relative average were used to rank strengths, weaknesses, opportunities and challenges in terms of degree of importance. The study produced the following findings; 1- The average percentage of total strengths was 77.4 %. The most powerful point was that farmers were advised that algae is generally accepted for agricultural production and were willing to apply to the fisheries and crop production at average of 4.64. At the very least, was where it contained significant bio-accumulators, large and micro-metal elements with an arithmetic average of 2.68 degrees. The percentage of the average total vulnerability was 73.5 %, with the greatest problems being with the extraction of security clearances for algae entry into the area with an average of 4.08 degrees. The least weaknesses were the absence of declared algal production and sale centers with an average calculation of 3.44 degrees. The average percentage of total opportunity points was 82.08 %. The greatest opportunity was to encourage the two earners to grow algae and diversity in agricultural production with an average calculation of 4.60 degrees. The lowest opportunities for applied scientific research with an average arithmetic of 3.64 degrees. The percentage of average total vulnerabilities was 79.2 %.
