Open Access Abstract A two-year study was conducted to test the effect of intercropping faba bean with fodder beet on the productivity of both crops, and land use efficiency of the system, when variable faba bean plant densities (D) were practiced, i.e. 42000 (D1), 84000 (D2), and 125000 (D3) plant ha-1, while three phosphorous fertilization (P) rates were tested, i.e. P1; 36, P2; 54, and P3; 72 kg P ha -1. 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.
摘要本研究采用不同的蚕豆种植密度(D)，分别为42000 (D1)、84000 (D2)和125000 (D3)株ha-1，同时施用3种磷肥(P)，即P1;36岁的P2;54, P3;72 kg P / 1。在2017/2018年和2018/2019年的生长季节进行了实地研究。研究了影响饲料用甜菜和蚕豆的农艺生理性状，并以土地等效比(LER)和干物质等效比(DMER)作为比较收获指标。结果表明，施肥72 kg ha -1磷可显著提高饲料用甜菜和蚕豆产量。调整适宜的种植密度，并强调间作优化的优点，以更好地改善作物。蚕豆种植密度(84000株ha-1)能影响饲料用甜菜的生长，而125000株ha-1强化对蚕豆的生长有影响。LER值均> 1,DMER值在0.92 ~ 1.06之间。研究证明，在干物质占经济成分主导地位的作物如饲料甜菜中，DMER比LER更可靠。

Open Access Abstract The United Nations Intergovernmental Panel on Climate Change's (IPCC) Special Report on Climate Change and Land (SRCCL), also known as the "Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems" is a landmark study by 107 experts from 52 countries. 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.

Open Access Abstract The study was carried out at the Faculty of Desert Agriculture and Environmental in Fouka, Matrouh University (Matrouh governorate) Egypt, during the two consecutive seasons of 2019/2020 and 2020/2021. 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.
