The treatments consisted of three ratios of 0.33, 0.55 and 0.71, were performed every 3 days at a constant volume of all nutrient solutions (300 ml/pot) during each growth season (28 weeks). A ratio of 0.71 proved to be optimal for chrysanthemum cultivation since it appeared to have the best results of vegetative characters (plant height, number of shoots and leaves per plant, leaf area, dry weights of roots and shoots, root/shoot ratio and relative growth rate), as well as inflorescence characters (days to flower, yield, fresh weight and stalk length). This ratio also followed the same pattern in relation to leaf pigments content and total carbohydrates, but this behavior was in direct contrast with flavonoids level. Although a ratio of 0.33 showed inferior results in growth and flowering, it was superior in flavonoids synthesis in leaves. The performance of a ratio of 0.55 was intermediate. The cationic ratios had an insignificant effect on phenolic compounds.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140520914","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}

Five indicators of desertification including soil factor, climate, soil erosion, vegetation, and land management to calculate the environmental sensitivity to desertification. The Desertification Sensitivity Model (DSSM) was designed to assess and map the sensitivity of land to desertification, depending on the weighted mean of some soil properties. The obtained data reveals that 5.03% (50.3 hectares, or 119.7 feddans) of the area is sensitive to desertification. While the area exposed to very severe sensitivity to desertification is about 94.97% (949.7 hectares, or 2260.3 feddans) of the studied area. The results obtained showed that the area under study suffers from desertification sensitivity due to mismanagement, topographic conditions, scarcity of vegetation cover, lack of exploitation of the land, soil quality, and wind erosion, as well as climate condition. Whereas the majority of the studied region is susceptible to desertification, it could be concluded that assessing its sensitivity is crucial for sustainable development measures to prevent it as well as for enhancing the use of natural resources. Additionally, the region requires significant efforts from everyone, including the Egyptian government, to counteract desertification through efficient management of the greatest hazards to sustainable development in the arid, semi-arid, and sub-humid areas of many countries.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322788","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}

Abstract Agriculture in Egypt is divided into two parts, traditional crops and non-traditional crops. Cumin and anise are two of the important crops that are grown in the city of Samalout. as their total cultivated areas were estimated at about 176 and 2150 acres, respectively, in 2021. However, the high costs of agricultural and production requirements led to the fluctuation of the cultivated areas of them, and thus the decrease in the amount of production. Therefore, this research aims to study and analyze the economics of the production of cumin and anise crops, with the aim of increasing the production of these two crops, and maximizing the return. In achieving its objectives, the research relied on the two methods of descriptive and quantitative economic analysis, as well as the method of simple, multiple and Stepwise regression. The results showed an inverse relationship between the amount of production per ton of the cumin crop and each of the number of human labor, the amount of mechanical work, the amount of seeds, the amount of chemical fertilizer, The quantity of the profit-maximizing output was estimated at about 4,006 tons. While the maximum amount of profit from the anise crop was estimated at about 5,335 tons, and the amount of optimal urban production for the average total costs amounted to about 2,743 tons. The research recommends more attention to medicinal and aromatic plants in general, cumin and anise crops in particular, and production according to economic rules.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322852","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}

A total number of 132 one-week-old Japanese quail were reared in batteries and assigned to 4 groups (33 birds /each). Birds in the first group (C) were reared under white light produced by LED light bulbs, while those in the second, third and fourth groups were reared under blue, green and red LED light, respectively. Experimental birds were raised in batteries under similar environmental and managerial conditions. Growth performance parameters (body weight gain, feed consumption, and feed conversion) were recorded weekly from 7 to 42 days of age and carcass traits were recorded at the end of the experiment. Light color significantly influenced body weight and feed conversion. Birds exposed to green or blue light had heavier body weights than those exposed to red light at 5 and 6 weeks of age. While birds exposed to white light (control group) exhibited intermediate body weights. The dressed carcass weights and gizzard percentages were greater in green color compared to that in red light group. It can be concluded that the use of red light should be avoided in raising growing Japanese quail birds and that green and blue light can substitute white light.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323335","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}

Abstract The agricultural sector is considered one of the most important commodity sectors of great importance in contributing to economic activity, as it contributes about 10.7% of the gross domestic product in Egypt, and also absorbs about 20.3% of the labor force, according to 2020 data, The value of agricultural production increased annually, and the average production about 242.49 billion during the period (2000-2020), representing about 11.79% of the real GDP, which led to an increase in the growth rate of real agricultural output and per capita output. On the other hand, the investments directed to agriculture have decreased, annually at a rate of 2.6% from the average value of the agricultural orientation index of government spending, which is about 0.16%. It was one of the main factors affecting agricultural output during the period (2000-2020). The study recommends some recommendations in order to: 1. increase the development and efficiency of water use and land resources. 2. directing more investments to the agricultural sector. 3. the need to increase the awareness of farmers and workers in the agricultural field of the importance of sustainable agricultural development .4. increase the value of agricultural exports and encourage to opening of new markets for commodities. 5. and increase the volume of credit granted to the agricultural sector.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323357","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}
