The Horticultural Export Improvement Association (HEIA) implemented new investments financed by USAID for the development of the cooling station and training district at Luxor Governorate in Upper Egypt with a storage capacity of 90 metric tons per day at L.E. 30 million investments. The Packing and Cooling Station was initiated in July 2015. The study reflects problem at the Cooling and Packing Station at Luxor Governorate. It does not operate at its maximum capacity of 50 tons per day. It operates for no more than two months and is currently inefficiently operating where the fees are higher compared to competitors. This is due to the lack of horticultural crops to operate. The objectives current study were to study the actual reality of the nine associations producing and marketing horticultural crops at Luxor and Qena Governorates, estimate the current and economic containment capacity of this logistic service of The Packing and Cooling Station (HEIA) at Luxor,estimate the financial feasibility of (HEIA) at Luxor, sensitivity measurement analysis through three scenarios to find out the station's ability to meet operational capacity fluctuations and price risk, developing mechanisms to economically operate The station and finally, the direct and indirect impacts were assessed in case of the economic operation capacity of the Packing and Cooling Station (HEIA). To achieve these objectives, the current study utilized questionnaires data at the level of nine associations dealing with the Project (Al-AMAL) during the season 2016/2017. Other information were from (HEIA) office data registers as well as information from some field and meetings obtained with parties who are concerned in this study. Analysis methods used the descriptive statistics of simple averages and percentages, SWOT analysis indicators, methods of quantitative analysis of financial feasibility study using the criteria of non-discount profitability and on discount profitability indicators. Basic solution results were calculated at a capacity of 23.9 thousand tons annual production. The findings indicated that when the service fee is L.E. 1250.5 per ton; the internal rate of return for the project is estimated at about 23% greater than the alternative opportunity cost of capital. It was also noted that simple average return on investment is approximately 11.2% and the payback period of investment was estimated at 8.9 years. The breakeven point of production was estimated at about 22.8 tons per day, representing 26 % of the operating capacity estimated at 88.1 tons per day.

However, the means of plant length, stem diameter, No. leaves/plant, root length and stem, leaves and roots fresh and dry weights of those plants were gradually decreased with increasing salinity level to reach the minimum values by the highest level (4000 ppm). The opposite was correct regarding the effect of Fe3O4, as the means of various top and root growth parameters were linearly increased as a result of the progressive increment of magnetite dose with the superiority of 4 g/pot dose that gave the highest records in most cases. The previous characters were also affected by the combined treatments, where the plants received magnetite at either 2 or 4 g/pot and irrigated with fresh water generally recorded the utmost high averages over control, and the interaction treatment of fresh water + 4 g/pot magnetite was the most effective one.

Also to estimate the degree of farmers response, the time required to respond and elasticity supply response in the short and long runs. To achieve the research goal, the descriptive and quantitative analysis methods used were suitable for measuring the supply response, Supply Response Impact. The research was based on data published by the Department of Economic Affairs, Central Department of Agricultural Economics, (in Arabic) in the Ministry of Agriculture and Land Reclamation, Egypt in addition to the published researches and the Arab and foreign scientific literature related to the research subject as well as the websites. The results showed the significance annual increase in the form price of the water melon crops (pound per ton) and some of the competing vegetable crops in the production season such as melon, Shahad, cantaloupe, and pumpkin. The annual increase in lag area of the watermelon crops and the lag area for competing crops was insignificant, indicating the stability of their averages. The estimated results of the Almon model showed a decrease in the value of elasticity coefficients in the short term, estimated at 0.40% , 0.08%, 0.71%, 0.62% and 0.32% for watermelon, melon, Shahad, cantaloupe, pumpkin respectively. While in the long term the elasticity was about 0.51%, 0.10%, 0.90%, 0.79% and 0.48%, respectively. The annual response rate was estimated to be about 0.78 (9.4 months), while the full response period was about 1.3 years, indicating a decrease in the supply response period for watermelon crops. This may be due to the possibility of expanding the area planted with watermelon after a year. The study recommends the need to expand horizontally and vertically in the cultivation of watermelon crops, and horizontal expansion by growing more new land with watermelon to increase production and increase market supply to reduce the price. Vertical expansion will increase the production of the unit area and increase the quality of production and introduce new early harvest varieties and types of watermelon.","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79516204","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 effect of the interaction between sowing time and soaking in Lena-tonik solution was also studied. The results indicated that the highest percentage of germination was obtained by sowing after 12 hr. from seed collection, as this treatment significantly increased the mean of this trait to 90 % in both seasons over all the other sowing times. Delaying sowing time to either 24 or 48 hr. significantly decreased germination percentage, while soaking the seeds in 1 ml/l Lena-tonik solution for any period raised germination percentage to 100 % regardless of the sowing time. The shortest time to either 100% germination velocity (G.V.) or 50 % mean germination rate (M.G.R.) was also achieved by planting the seeds after 12 hr. from harvest and by soaking in Lena-tonik solution.
