CURRENT DEMAND FOR WATER RESOURCES IN EGYPTIAN AGRICULTURE
2019
M. Ibrahim | S. Makled | A. Elsabea
Water is one of the most important inputs and elements of development, and the importance of water in Egypt is increasing due to the lack of resources and increased demand in recent periods, where rain is scarce and covers most of its deserts. The River Nile is the main water supplier in the Arab Republic of Egypt, where the share of the river about 55.5 billion cubic meters per year, and the problem is limited to the study of the current and future use of water, while Egypt suffers from the constant amount of water available to cover these uses, The high rates of Egyptian population growth, with Egypt's share of water remaining constant, and hence the problem of water shortage, is a threat to the national economy in general and the agricultural sector in particular. The aim of the study is to use water for the time being and to work to increase the efficiency of water use in future years The study shows that the quantities of water used in irrigation for agricultural crops in Aswan fluctuated between the minimum and the decrease, ranging between a minimum of about 40.1 billion m3 in 2012 and a maximum of about 62.1 billion M3 in 2008 with an annual average of about 50.48 billion m3 during the same period. And the study of the equation of the general time trend for the quantities of water used for irrigating agricultural crops in Aswan and it shows that there is no mathematical picture suitable for the nature of the data and that the data revolve around the mean arithmetic.

Medicinal and aromatic plants are considered to be non-traditional, multi-use crops, both in their direct form and in their indirect form, through the extraction and use of active substances in the pharmaceutical industry, the food industry, perfumery, cosmetics and soap, either in the form of pills, plants or medicinal and aromatic herbs. The cultivated area of medicinal and aromatic plants in Egypt amounted to about 46.2 thousand feddans with a percentage of 0.27% of the crop area of about 15.525 million feddans in the agricultural season (2011-2018). The cultivated area of the study crops was about 20.21 thousand feddans, The company has about 48.15% of the area of medicinal and aromatic plants during the period (2011-2018), and Egypt is located in the markets of medicinal and aromatic plants worldwide, with a trade volume of more than 60 billion dollars annually, which is a major exporter of 158.94 million dollars Which is equivalent to about 1127.038 million pounds in 2014 representing about 3.07%, 0.594% of the camel The value of Egyptian agricultural exports and total exports of 36.711, 189.741 billion pounds respectively in 2014, the problem of the study is that the cultivated areas of medicinal and aromatic plants are limited and fluctuating and low in some cases, where in recent years the areas of latency and rumen decreased from about 5,545,99759 years 2010, 2017, 2016 to about 5.152, 98759 acres in 2018, and although it is profitable crops for the farmer and the new land can be a good solution to compensate for the cost of reclamation, and this reflects on the domestic production of the failure to meet the needs of export and meet the needs of the company V Local of medicinal and aromatic plants. In spite of the urgent need to increase exports, the deficit in the Egyptian trade balance is about 329.085 billion pounds in 2017. The study examined the productive and economic indicators of the most important medicinal and aromatic plants in Egypt. The cultivated areas of the study crops declined. The latency decreased by 5.1% With an average area of about 3,616 feddan and an average area of about 3651 feddan, while the average area of the basil was about 10.685 thousand feddans, while the average value of cash amounted to about 29,072, 41.561 million pounds for the quail and basil respectively, The value of their exports continues to rise by 10.6%, 15.42% from the average of 3866.8 and 2553 thousand dollars respectively for the period of study, as well as the increase in quantities exported from cumin and monetary value by 11.79% from the average of 1047 tons and 16.45% The statistical estimate of the production of the most important medicinal and aromatic plant crops in the sample of the study, Cumin and Rihan, was examined to determine the economic efficiency and productivity of the agricultural resources available and used for each and their importance in Egyptian agriculture, Illustrates the high economic efficiency of the majority of the elements of production of crops, cumin, basil sample study of farmers Samalout and Beni Mazar of basil in Beni Suef governorate, low economic efficiency of the element of seeds in crop cumin, manure and municipal phosphate crop basil which requires rationalization of the use by farmers of cumin sample study. The study also included the statistical estimation of the production cost functions of the most medicinal and aromatic plants in the sample of the study. Finally, the study dealt with the quantity, value and price of Egyptian exports of basil and cumin.

The present work is aimed to isolate, purify, identify a newly isolate Rhizobium fabae from different regions in Egypt then, produce and optimize Poly-β-Hydroxybutyrate polymer (PHB) production by the selected isolate Rhizobium fabae F44 using a statistical approach of response surface methodology (RSM). Rhizobium fabae F44 isolate was picked up from Sharkia Governorate in Egypt and then identified by the 16SrRNA gene as Rhizobium fabae. Eleven different variables which affect the production of PHB polymer were screened by Plackett–Burman statistical design approach. Maximization of PHB production was adjusted by the terms of The Face Central Composite Design (FCCD) of RSM and assessed at three coded levels (–1, 0, +1). One way Anova was used to statistically analyze all obtained results in relation to post hoc multiple comparison analysis performed by Tukey’s HSD. Appulses of nutritional and physical factors (two carbon sources, two nitrogen sources, mineral salts, pH, temperature, incubation time, inoculum size and agitation rate) were studied using Plackett-Burman design method. 58 isolates were obtained from the different 9 governorates with 100 % infection plant technique. The 16SrRNA showed a similarity of 99.56 (%) to Rhizobium fabae F44. Out of all tested significant media components, sucrose, yeast extract, agitation rate had the highest significant effects on the response as for PHB production, with confidence level > 98% and were further optimized using FCCD. Predicted Maximum PHB production was observed as (78.51%) which in near the mid-point (0) values (concentrations) of sucrose which reached (25 g/l) and yeast extract of (0.5 g/l) for 48 hrs. at 150 rpm agitation rate. The observed experimental value reached 87.5u/ml was very close result to the predicted one validating the model. So, Response Surface Methodology is an effective statistical approach which can substitute the use of one variable at a time approach due to its adequacy and efficiency to optimize PHB production by Rhizobium fabae F44.

The purpose of this study is to improve texture, flavor and overall quality of low-fat white soft cheese. Using sodium caseinate (SC) and / or butter milk powder (BMP) in different ratios. Buffalo’s milk was divided into two portions. The first portion was standardized to 3% fat and served as a control (1). The second portion was standardized to 1% fat and sub divided into five parts, the first part was served as control (2), the second part fortified with 2% SC (T1), the third part fortified with 2% BMP (T2), forth part fortified with 1% SC + 1% BMP (T3) and fifth part fortified with 0.5% SC + 1.5% BMP (T4). All cheese treatments stored in salted whey (5% NaCl) at 5±2°C up to 3 months. The results indicated that, control (2) had obviously lower moisture content than control (1). Addition of sodium caseinate and / or butter milk powder to cheese milk led to an increase in moisture content of resultant cheese compared to control (2). A slight increase was observed in total nitrogen % of low-fat all soft cheese treatments versus control (2) being more obvious in T2 and T3. Low-fat soft cheese treatments were characterized by higher soluble nitrogen % than control (2). Moreover, the results showed also that, replacing of milk fat with SC + BMP caused a decrease in hardness, adhesiveness, springiness, chewiness and gumminess in fresh cheese compared to control (2). Sensory properties of Low-fat soft cheese were highly improved by adding SC + BMP to cheese milk as a fat replacer. Low-fat soft cheese was most preferable in T3 with adding SC + BMP (1:1), those improved the compositional as well as the organoleptical properties, especially its body and texture of low fat brined soft cheese after 90 days of cold storage.

A total of 320 fertile eggs, were divided randomly into 4 treatments with four replicates and 20 eggs per each replicate. Treatments including: T1; control; without injection, T2; injected with 0.1ml saline solution; sham control, T3, injected with0.1 ml either containing 0.75 ppm inorganic or Nano – iron particles 75 ppm Fe-Nano inorganic, T4, injected with 75 ppm Fe inorganic On the 7th day of incubation, 0.1 ml solution was In ovo injected into the egg .Body weight and body weight gain were measured at biweekly intervals, at 42d of age, three hens per replicate were weighted, sacrificed for slaughtering weights of carcass, internal organs(heart, liver, and lymphoid organs i.e. (spleen, thymus and Bursa) were recorded. Blood samples were collected at slaughtering bird at 42d of age. There were significant increase in body weight and body weight gain in treatments injected with75 ppm Fe-Nano inorganic and 75 ppm Fe inorganic compared with control. There were no significantly differences among all experimental groups in dressed carcass, gizzard, and heart, liver. Abdominal fat decreased in groups injectedwith75 ppm both iron forms. Compared with the control group. No variation was observed in the weight of bursa and spleen, however thymus weight was significantly higher in both Fe inorganic and Fe nano inorganic injected groups than un-injected control group. High density lipoprotein concentration and cholesterol were significantly decreased by different treatment as compared with the control group. These results suggest that, 75 ppm Fe inorganic or75 ppm Fe-Nano injection at the 7th im proved at the 7th day of incubation improved embryonic growth and development as well as decreasing post hatched chick's plasma cholesterol.

Salinity is a major limiting factor for tomato crop growth and productivity especially in arid and semi arid lands region. Therefore this study was conducted to study the effect of applying sugar beet molasses, priming tomato seedling in saline water and Fe-EDHHA on mitigating salinity negative effects on tomato (Lycopersicon esculentum L.) hybrid super strain B (salinity sensitive hybrid). Seedlings of tomato hybrid were transplanted on April 4th in both seasons 2014 and 2015 in pots contains washed sandy soil, and irrigated with saline water with EC of 2000, 3000 and 4000 ppm. Beet molasses and Fe – EDHHA were applied at rates of 200 and 300 kg / fed. for beet molasses and 3 and 4 kg / fed. for Fe – EDHHA. Priming tomato seedlings in saline water treatment was applied at 5 and 6 dS/m for 24 hours. Data showed that all plant growth aspects such as plant height, leaf area, plant fresh and dry weights were improved under beet molasses, Fe and priming tomato seedlings in saline water treatments compared to none treated plants (control). Yield parameters also followed the same trend. Among treatments, beet molasses at a rate of 200 kg / fed. recorded the highest significant effect in mitigating salinity negative effects. It could be concluded that beet molasses, priming tomato seedling in saline water and Fe – EDHHA treatments were more effective and efficient in mitigating salinity stress on tomato plants.
