Over the past few years, concerns regarding water scarcity and pollution have become more prominent. In many regions, water supply management requires support. This study aimed to determine the effect of greywater on vegetative parameters and chemical content on the yucca plant by using pots studies under greywater stress. This study was carried out in pilot plant of the experimental area, National Research Centre, Dokki, Cairo, Egypt, during the two successive seasons of 2021-2022. Yucca plants were irrigated with greywater at different dilutions by tap fresh water at the following percentage of greywater: 50%:50% (50%greywater,50% tap water); 67%: 33% (67% greywater, 33% tap water); 75%:25% (75% greywater, 25% tap water);100% (100% greywater, 0% tap water) while the control samples were irrigated with tap water only. It was found that irrigation of yucca plant with raw grey wastewater recorded the highest values in the proline content, protein and chlorophyll a, b in the plants, while all the vegetative parameters were decreased. By irrigation with 75:25 greywater (i.e., 75 % greywater: 25% freshwater), higher values in cell carbohydrates content were recorded compared to the control (i.e.,100% tap water) and other treatments. On the other hand, irrigation with 67% greywater recorded the highest values in vegetative parameters, followed by irrigation with 75% greywater in comparison with the control one (tap water). From this study, it was concluded that long-term irrigation with greywater exhibited a beneficiary effect on Yucca plant.

Income from the livestock and poultry production sector is one of the most important components of the Egyptian national income from the agricultural field, although it suffers from a fodder gap (Poultry Producers Federation in Egypt, 2019). The feed deficit has been estimated at about 6 million tons per year, so feed components are imported in hard currency to fill this feed gap, so the search for non-traditional local sources of feed, components or substitutes can contribute to filling Egypt's feed deficit (Livestock Annual Bulletin, 2019). Poultry slaughterhouse waste contributes to the production of large quantities of feed concentrates, which can contribute significantly to solving this problem, filling the existing feed gap, and will also save a lot of hard currency in which feed concentrates are imported from abroad, which will have a positive impact on the Egyptian trade balance (Saad, 2022). Therefore, the research aimed to conduct a financial and economic evaluation of the recycling of poultry slaughterhouse waste to maximize its utilization and raise the added value of poultry production projects, in addition to reducing the pollution resulting from it, as it is one of the main obstacles to poultry production projects. The results of the financial measures showed that the revenue/cost ratio (B/C) at 13% discount rates 16% of the center's production of 50% protein from poultry massacres with no change in cost and revenue factors and the life of the project has reached about 2.6%, which confirms the feasibility of the project, The income-to-cost ratio is greater than the correct one, which means that each pound invested in the project yields an estimated net return of 2.6 pounds. As well as net current cash flows or net present value of the project (NPV) is about 63940, 53015 thousand pounds per discount factor of 13%, 16% respectively. The internal return rate of the project (IRR) was about 14.6%, meaning that the rate of return is greater than the opportunity cost prevailing in the society at the time of the study, namely the rate of interest of 12.3%. The recovery period of the project's capital was therefore estimated at about 6.8 years, which confirms that there is a speed in the recovery of capital. It is evident that the project is economically viable.

This research was conducted at the faculty of agriculture, Ain Shams university, Shubra El-kheima. The research aimed to test the effect of selenium (Se) and nano-selenium (NSe) on green bean to mitigate the cold temperature stress. Green bean seeds were sown late (mid-December) with low temperatures in open field (open) and under low tunnel (cover). Green bean plants were sprayed with selenium (Se) or nano-selenium (NSe) with four concentrations (0, 2, 4and 8 ppm). Cultivating green bean under low tunnel produced the highest vegetative and yield characteristics compared to open cultivation. Spraying plants with 8ppm NSe significantly increased the following parameters in the first season (2017) and second season (2018), respectively: plant height was (48.50 and 45.83 cm), number of leaves (7.17 and10), and nitrogen % in leaves (4.13 and 5.28), yield (2872 and 3029 gm) and reduced proline content in leaves (825 and754) compared to 0 ppm. Spraying green bean plants with NSe enhanced the following parameters;
