Field studies were carried out during the growing season of 2017/2018, and 2018/2019. Some influential agronomic, and physiological traits for fodder beet and faba bean were investigated, besides, land equivalent ratio (LER), and dry matter equivalent ratio (DMER), as comparative harvesting indices. Results indicated that 72 kg ha -1 P fertilization could significantly boost production of fodder beet and faba bean. Adjusting suitable planting densities, also emphasized the merit of intercropping optimization for better crop improvement. Plant density of faba bean (84000 plant ha-1) was able to impact the growth of fodder beet, while faba bean was impacted by practicing 125000 plant ha-1 intensification. All LER values recorded > 1, while DMER figured between 0.92 and 1.06. The study evidenced that DMER was more reliable than LER for appraising intercropping, in cops where dry matter dominates an economic component like fodder beet.","PeriodicalId":142760,"journal":{"name":"Journal of Desert and Environmental Agriculture","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124634936","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 SRCCL provided a comprehensive overview of the entire land-climate system for the first time and decided to enlist land as a \"critical resource.\" On Wednesday, August 7, 2019, in Geneva, Switzerland, the IPCC's 50th session (IPCC-50) adopted the SRCCL's Summary for policymakers (SPM) and approved the report. The report is the second of three Special Reports in the current Sixth Assessment Report (AR6) cycle, which began in 2015 and will be completed in 2022. The third chapter of the special report deals with the relationship between desertification and potential climate change. It reviews research on desertification-affected oases and the impact of climate change in the Kingdom of Saudi Arabia, Egypt, and Tunisia. This review paper discusses oases in hyper-arid climates as affected by climate change. Emphasis has been lent to the Siwa Oasis as an example of the areas impacted by climate change in Egypt. Concluding remarks and recommendations have also been provided to tackle climate change in affected oases. Hussein, I.S. , and Ali, A.M. 1.

The investigation aimed to study the response of Duranta erecta L. Var. Variegata plants to the proline concentrations (0.0, 40 and 80 ppm) and ascorbic acid concentrations (0.0, 100 and 200 ppm) under irrigation by seawater levels (0.0, 2000, 4000 and 6000 ppm) and their combinations on plant growth and some chemical constituents of Duranta erecta L. Var. Variegata plants. The study was designed in a split-plot design in random completely block design (RCBD) with three replications. In this experiment, the main plot was salt water levels and the sub-plot was spraying by proline and ascorbic acid treatments. The obtained results showed that irrigation plants with salinity levels (2000, 4000 and 6000 ppm) significantly decreased growth parameters; number of branches, number of leaves per branch, leaves fresh weight per branch, stem diameter, leaf area, total leaf chlorophyll contents, total carotenoid contents, leaf relative water content, leaf proline content and some chemical constituents (N, P, Fe, Mn) compared to control. Moreover, the highest values were recorded by proline at 80 ppm followed by 200 ppm ascorbic acid in both seasons. This study showed that treated plants with proline and ascorbic acid alleviating the negative effects of salinity stress on duranta growth.","PeriodicalId":142760,"journal":{"name":"Journal of Desert and Environmental Agriculture","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115709988","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}
