The present study aimed to justify the effects of restricted feeding periods during last month of pregnancy and initiation of lactation on growth rate of Maghrebi she-camel and their offsprings. Sixteen pregnant she- camels with an average body weight 512.74 kg were divided randomly into three groups. The first group (G1) was fed 100% of their daily requirements concentrates. The second group (G2) was offered 75% of their daily requirement of concentrates after delivery for one month, while the third group (G3) was fed on 75% of their daily of concentrate requirements for two months (one month pre and another one post-partum). New born calves were divided after one month of lactation to four groups as following; calves born G1 dams were divided randomly to two subgroups. The first one (G11) suckled their dams naturally, while the other (G12) was artificial reared on a milk mixture (50% natural camel milk and 50% cattle milk replacer). Calves born to G2 and G3 dams were artificial reared on a mixture 50% natural camel milk and 50% cattle milk replacer. Results obtained showed that she-camels of G1 gained insignificant more live body weight than that of G3 during the pre-calving period 49.09 vs. 42.05 kg, respectively. There were insignificant differences among the 3 groups in calves birth weight 30.44, 32.8 and 29.73 kg, respectively. During lactation period, she-camels of G1 produced insignificantly more daily milk in compare with the corresponding she-camels of G2 and G3 (3.78 liter vs. 3.32 and 3.4 liter/ animal), respectively. She-camel of G3 lost significantly (P˂0.05) more LBW from the beginning of the experiment to the end of the study in compare with both of G1 and G2 she-camels. Calves of one month of age and born to G1 dams indicate faster (P˂0.05) daily gain (0.326 kg / h/ day) than those to both of G2 and G3 dams. Three months old age calves of different groups, indicated nearly similar growth, regardless of their dams feed restriction and type of calves rearing (natural vs. artificial). Data obtained showed also that neither she-camels feed restriction practice nor type of calves rearing have any significant effect on either calves daily gain or dams final LBW after 3 months of treatments.

It is one of the most serious problems facing Egyptian agriculture, which is working to eat agricultural area Where farmland represents one of the most important agricultural economic resources in the provision of food, where is the problem of constant encroachment on farmland and converted from agricultural use to other uses of non-farm as the total agricultural land has been encroached upon construction during the period Area (1983 - 2010) about 64 Thousand acres in addition to the encroachment on about 38.46 thousand acres since the wealth of January 25, 2011 until 28/9/2014, which led to a decline in the average per capita agricultural land in Egypt from about 0.133 acres / population in 1983 to about 0.112 acres / people in 2011, was where the study problem in increasing encroachment on the land Agricultural Giza especially governorate Doanh the post-January 25 Revolution 2010 study was conducted to identify the effects of Aguetsadahoalajtmaih leveling farmland in Giza Governorate 2017 season. Where the characteristics and motives of the establishment of private projects and land has been identified, and this motivation strengthens the doctrine of the importance of infringement by seeing others from projects that are based on their negative impact on the neighboring lands of the project, especially if the success of the project and the desire to imitate this behavior or create a new project The previous project, whether through raw materials or taking advantage of the product of the former resident on the lands beyond it, which sees the oppressor as an incentive for the tradition and Altadam on the infringement of the other and waiting for what happened to him before the establishment of a plant on the land beyond it and did not see the behavior of Alchk Meh it packs serious and immediate accountability and behavior, whether or removal or punishment Salehbh both. It was concluded that the owners of the first Mivkron project is the amount of income obtained by the search for the compensation of what was obtained before the establishment of the project and shows the table what the project owner gets from the agricultural land before the establishment of the project and the income obtained after the establishment of the project and depends on the difference in income, The project, where it was found that the owner of a poultry farm was obtained on average on 94.4 pounds / month as the value of rent or equivalent percentage of the crops produced from the area on which the project is established (poultry farm, which is 5.28 i), while the increase rose to 12.3 thousand pounds, increase of about 13.56% than once The average monthly income before the establishment of the stadium amounted to about 193 pounds / month, which rose about 8 thousand pounds / month, an increase of about 4145% of what was obtained of the agricultural land, while the income of the owner of the wedding hall before the establishment of about 113.3 pounds / month of agricultural land, while the rise to about 4 thousand pounds from the wedding hall, an increase of 3530% of what was obtained from the ground. Although the satisfaction of the projects on the land above it is much higher than the return of agricultural land, this high return of projects does not correspond to the degree of food deprivation for future generations as a result of conversion of agricultural land to special projects in all wars and the occurrence of fodder or influence the political decision to import food and provide of society as a whole.

The research aimed to study the effect of reducing water voracious crop areas, such as (rice, sugar cane, bananas, alfalfa) on the available water quantity in the agricultural sector, where the data analysis showed that the most of the voracious crops especially rice and sugar cane are concentrated at the old lands within the valley as it explained in the research later, therefore, the research focused on inventory and analysis of the old land data within the valley to determine the best alternatives of the cropping pattern which achieves the state's goal of saving water and maximizing the return of the water unit, and is compatible with the current local, regional and environmental water conditions and the future developments that may occur in the future, that by using linear programming, through three models that have been formulated: the first is minimizing water requirement, the second model maximizes the net of acre return, while the third model maximizes the return of the water unit, using available data published and unpublished issued by the concerned authorities. The research focused mainly on the possibility of reducing the water needs of cropping pattern as a main objective, in addition to increasing the self-sufficiency ratios of strategic crops through the first scenario, and increasing the areas of export crops to increase the export proceeds through the second scenario, as far as possible within the available water and land area in the study area, using different statistical models. The results of the analysis of the statistical models in the first scenario showed that the total quantity of irrigation water available for the cropping pattern of the study crops reached 41.483 billion m3, while 38,604, 38.726, 38.683 billion m3 were used for the statistical models respectively, this indicates that the required water quantities decreased by 2.879, 2.758, 2.800 billion m3, with a change rate of about 6.94, 6.65, 6.75% for the statistical models, respectively. The net return of the water unit for the actual cropping pattern reached about 1.634 LE/m3, while it reached about 1.755, 1.767, 1.765 LE/m3 for the statistical models respectively, which shows the increase in net return of water unit by 0.122, 0.133, 0.131 LE/m3, with a change rate of about 7.46, 8.17, 8.05%, for statistical models respectively. The second scenario aims beside minimizing the water needs of cropping pattern, increasing export crop areas such as onions, peanuts, potatoes, tomatoes and other vegetables as much as possible, assuming situation stability of foreign trade. The results of the analysis of the statistical models in the second scenario showed that the total quantity of irrigation water available for the cropping pattern was about 41.483 billion m3, while 38,471, 38.912, 38.803 billion m3 were used for the statistical models respectively, indicating that the required water quantities decreased by 3.013, 2.572, 2.681 billion m3, with a change rate of about 7.26, 6.20, 6.46%, for statistical models, respectively. The net return of the water unit for the actual cropping pattern was about 1.634 LE/m3, while it reached about 1.773, 1.830, 1.833 LE/m3 for the statistical models respectively, which shows the increase in the net return of water unit by 0.139, 0.197, 0.199 LE/m3, with a change rate of about 8.53, 12.04, 12.21%, for statistical models respectively. Crop rotations can be applied to the new lands using water savings including (wheat and maize), with an area ranging from 2048 to 2399 thousand feddans, and including (wheat and summer and nili vegetables), with an area ranging from 2941 to 3444 thousand acres, also including (maize, winter and nili vegetables), with an area ranging from 3432 to 4021 thousand feddans. With regard to the impact of reducing the area of water crops to water gap which reached about 20.9 billion m3, it decreased by about 2.879, 2.758, 2.800 billion m3, which make water gap decreased to about 18.02, 18.14, 18.10 billion m3, with change rate of about 3.77, 3.61, 3.66%, for statistical models respectively, while the results of the second scenario show decreased of about 3.013, 2.572, 2.681 billion m3, which make water gap decreased to about 17.89, 18.33, 18.22 billion m3, with change rate of about 3.94, 3.37 and 3.51% for statistical models respectively. The research recommends the following points: 1. Reduce the areas of rice, sugar cane and alfalfa to save a quantity of water ranging between 2.572 - 3.013 billion m3 of land within the valley. 2. Using of water savings resulting from reducing the areas of water crops to expand the cultivation of new land with strategic and monetary crops. 3. Sugar beet area can be expanded at least to the extent that it covers the shortage of sugar production caused by reducing the sugar cane area, then taking into account and study the effects resulting from that. 4.

Salinity is one of the major environmental factors limiting crop productivity. For this reason, two greenhouse experiments were conducted in Faculty of Agriculture, Cairo University, Egypt, during the year 2015 using two rice varieties to evaluate the effects of various levels of osmotic stress caused by polyethylene-glycol 6000 (PEG) and NaCl. Furthermore, it was tested whether the inhibitory effect of salinity on growth, sodium and chloride concentration by two different varieties was greater under NaCl or PEG treatment. The first experiment was undertaken to separate osmotic and ionic aspects of salinity damage to rice (Oryza sativa L.).Seedlings of IR28 (salt-sensitive) and Nona Bokra (salt-tolerant) rice varieties were transferred to salinized nutrient solution containing 85 mol m-3NaCl (-3.0 bars) with or without PEG 6000 (-2.0 bars, 45 gL-1). Plants were grown up to 30 days in the salinized solutions. The second experiment was designed to determine the effect of salinity (85 mol m-3NaCl) with or without PEG 6000 (-0.5 bar, 11 g L-1)on growth, uptake and transport of sodium and chloride in two rice varieties differing in salt tolerance. The results indicated that survival of salt-tolerant variety (Nona Bokra) was increased significantly by adding PEG (-2.0 bars). The addition of PEG also reduced the rate of death of rice plants compared with NaCl alone. Also, data showed that PEG 6000 (0.5 bar, 11 gL-1) reduce sodium concentration in root of IR28 and Nona Bokra but its effect upon sodium concentration in shoot of the two varieties was more pronounced than the reduction of Na+ concentration in root. Highly significant differences were obtained between zero and 11 gL-1 PEG. The result of this study is strongly indicated that addition of PEG dramatically lessened the toxicity of NaCl to rice seedlings.

Egypt suffers from future risks due to lack of water especially in the downstream countries, Egypt and Sudan, which depend on the Nile water almost entirely and the upstream countries are moving to raise problems with Egypt and erect dams and pressure on Egypt to achieve the greatest economic benefit possible to prevent Egypt from horizontal agricultural expansion. Egypt is the largest and most dependent country on Nile water, with almost no rainfall. Groundwater is not renewable. Thus, the Nile water accounts for about 97% of Egypt's water resources and the share of the Egyptians is 55.5 billion m3, this quantity of water is insufficient to the needs of the population, and in order to maintain Egypt's per capita water, it needs about 80 billion m3, which means a deficit of 25 billion m3 and stability of Egypt's share of the Nile water under current local, regional and global conditions, and development of the appropriate strategy to alleviate the conflict with the basin countries Nile River so the study aimed to compare production efficiency and the economics of the irrigation systems used in the province of the lake through the study of water user associations in agriculture under the different irrigation patterns within water users association and outside association to rationalize the use of water and raising awareness to increase productivity. The results of the estimation indicated that the economic efficiency indicators of the maize and potato crop farmers in the sample of the field study show the preference of the use of the production function in the logarithmic formula to the different variables affecting the productivity of the crops according to the irrigation systems within the water user associations The results showed that the total production elasticity of maize crop was about 0.720, 0.530, 0.348 for sprinkler & drop, developed irrigation, and padded flooding systems, while the value of (R2) was about 0.76 , 0.60, 0.63 for irrigation systems respectively, The results showed that the total productivity of the potato crop was 1.127, 1.16, 1.318, for sprinkler & drop, developed irrigation, and padded flooding systems respectively, while the value of (R2) was about 0.76, 0.62, 0.70 for irrigation systems respectively. The relationship between the total costs and quantity produced of maize, which showed that the quadratic formula is the best formulas for the data, and the equations show that there is a statistically significant positive relationship between the total costs and production of maize in Behera Governorate. In the estimation of the optimal production volume, which reduces the costs is estimated at about 18.7, 22.1, 23.9 ardab/feddan, for sprinkler & drop, developed irrigation, and padded flooding systems respectively. In the estimation of the production volume which maximizes profit, the results showed that this volume was not reached, 29.1, 36.1, 31.9 ardab/feddan, for sprinkler & drop, developed irrigation, and padded flooding systems respectively. Calculating cost elasticity, it reached about 1.19, 0.804, 0.719, for sprinkler & drop, developed irrigation, and padded flooding systems respectively. In order to determine the optimal production volume of the potato crop, which reduces the costs, so make average cost equal marginal costs, estimated at 12.539, 11.377, 11.064 tons/fed, for sprinkler & drop, developed irrigation, and padded flooding systems respectively. The size of production of potato that maximizes profit was about 42,500, 33.350, 25.600 tons/fed, for sprinkler & drop, developed irrigation, and padded flooding systems respectively. Calculating the cost elasticity of the potato, it turned out that it was about 0.93, 0.804, 0.719 for sprinkler & drop, developed irrigation, and padded flooding systems respectively. Production efficiency measures are (7), the study of the efficiency of production of maize crop for members of water associations in the sample of the study in Behera Governorate.

2017
Sanaa Sadek
The United Nations announced in 2016 was as international year for Legumes crops. As a part of sustainable food production, legumes are playing a vital role in Egypt for providing people with their needs from plant protein and amino acids. In general, Egypt suffers a gap between domestic production of legumes and consumption needs, particularly of Faba bean, and lentil. Thus, self sufficiency ratios reached 39% and 1.6% for both crops in 2014 respectively ([1]). Consequently, the imported amounts from both products were increasing during 1993 and 2014. So that the average of import value of Faba bean reached to LE 1.7 milliards alone, while lentil reached to LE 583.4 millions during 2010 and 2014, which represent about 66.2% and 22.3% respectively from the average import value of legume crops. Due to spread Balkiros injury in 2011, the cultivated area and domestic production of Faba bean has been significantly declined so that import value was increased. While, Faba bean domestic production represents about 78% of total legumes production, lentil represents only 1.3% as average of the period (1993-2014)([2]). The present paper aims to: (a) Identify the most important productivity and consumption indicators for leguminous crops in Egypt by using the equations of general time trend during the period (1993-2014).
