Agric., Minia Univ. throughout the two growing seasons of 2022 and 2023 to teste the influence of humic acid at 0.0, 1000, 2000 and 4000 ppm on Rosmarinus officinalis growth characters, essential oil production and some chemical compositions, planted under irrigation salinity (0.0, 800, 1600 and 2400 ppm NaCl). Data showed that all examined traits of vegetative development (plant height, branches and leaves number, stem diameter, leaf area, herb fresh and dry weights), essential oil productivity (% and yield ml/plant) and some chemical compositions (pigments content and NPK%) were decreased by increasing salinity level comparing with control during both seasons. At the same time, salinity concentrations increased both of Na% and proline content (µg/g) in dry leaves during both seasons. Humic acid treatments significantly increased all abovementioned traits of vegetative development and volatile oil content as well as some chemical compositions except Na% and proline content (µg/g) in dry leaves during both seasons, were decreased. The best treatment was 4000 ppm humic acid in this concern. In conclusion, treating plants with 4000 ppm humic acid can alleviate the bad effects of moderate salinity levels.","PeriodicalId":429950,"journal":{"name":"Scientific Journal of Agricultural Sciences","volume":"110 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140276548","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}

Agric. Scie., Arish University during the period from 2019-2021 to identify an effective, simple, and rapid protocol for improvement the frequency regeneration of Jatropha curcas plantlets, depending on modification of various media, including MS, B5, and WPM. MS modified with 0.5 mgl-1 N-phenyl-N'-l,2,3-thidiazol-5-yl urea (TDZ) + 0.5 mgl-1 BA + 0.1 mgl-1 IBA resulted in the highest induction of adventitious shoot buds (5.3) in Ecuador line and (4.7) in Madagascar line from leaf culture. In in vitro rooting stage of different Jatropha, stable elongated shoots were then planted on half-strength MS, B5, and WPM medium, all of which contained varying concentrations of IBA. The MS medium modified with 0.5 mgl-1 IBA provided the largest frequency of root induction. The highest number of roots/shoot (6.06) with (2.93 cm) root length for Ecuador line, therefore, the largest number of roots/shoot (5.76) with (2.76 cm) root length for Madagascar line, after 6 weeks of culture. In the greenhouse, the in vitro Jatropha plantlets were successfully acclimatized and survived to other study in the future and it could be concluded that, the modified MS medium with TDZ or IBA and Ecuador line were more effective for leaf culture technique..","PeriodicalId":429950,"journal":{"name":"Scientific Journal of Agricultural Sciences","volume":"90 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139192463","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}

Forty-eight weaned female V-line rabbits were divided into six groups (8 each). 1st and 2nd groups involved TW whether exposed to magnets or not (TW vs. MTW). The other groups involved the well water using the same method while the 3rd and 4th groups with TDS 4000 ppm (WWA vs. MWWA) and the 5th and 6th groups with TDS 6000 ppm (WWB vs. MWWB). The results indicated that magnetization had a higher impact on WW, whether 4000 or 6000 ppm than on TW. Feed intake significantly (P < 0.001) decreased, while average daily gain, growth rate, and feed conversion ratio significantly (P < 0.001) improved. WW reduced (P < 0.001) litter size, litter weight at birth & weaning and milk yield compared to TW. WW reduced (P < 0.001) serum protein profile, liver enzymes, ovarian hormones, and aldosterone hormone but raised serum sodium and chloride. When water was exposed to a magnetic treatment boosted (P < 0.01) litter size, litter weight at birth & weaning and milk yield and enhanced milk conversion ratio and improved levels of liver enzymes, and ovarian hormones compared to unmagnetized water. The use of magnetization, particularly in salt water, reduces the adverse effects of salinity and enhances the quality of the water.","PeriodicalId":429950,"journal":{"name":"Scientific Journal of Agricultural Sciences","volume":" 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139196243","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}
