Fattening cattle projects represents an important role in the agricultural economy, as these activities contribute by about 36% of the total value of agricultural production, amounting to about 159.09 billion Egyptian pounds. The average value of medium term livestock loans presented by the Bank of Development and Agricultural Credit during the period (2000-2012) was about (3 – 7.8) million Egyptian pounds, respectively. The search was a problem in that in spite of the availability of many economic possibilities and productive conditions that support and strength the chances of success of fattening cattle projects New Valley Governorate it was shown that Governorate has a Weak Contribution in Live stock Production. The objectives of these research is studying productive and economic efficiency for fattening cattle through some economic and technical relations to identify the most important factors that affect the economic efficiency in production. These objectives   has been realizing depending on two methods of data collection, the first depends on secondary data, and the second depends on the primary data through using questionnaires to collect data a sample of  cattle breeders at (Mott, acement, balat villages) at Dakhla district. The study used qualitative and quantitative statistical methods to achieve the objectives of the study, such as the equations of time trend in it's linear and quadratic, cubic, forms and use multi-phased regression method. The most important results that research can be summarized as follows: Decrease in short-term current value animal loans by annual rate of about 0.37 million pounds.  Decrease in short-term real terms animal loans by an annual rate of about 0.23 million pounds. Decrease in medium-term current value animal loans by an annual rate of about 0.95 million pounds.  Decrease in medium-term real terms animal loans by an annual rate of about 0.34 million pounds.  Increase numbers of cows by an annual rate of about 11.1 thousand units.  Decrease the numbers of buffalo by an annual rate of about 0.03 thousand units. Increase the numbers of sheep by an annual rate of about 4.9 thousand units. It shows also the in significance of increasing    the numbers of goats. Declining numbers of camels by an annual rate of about 0.28 thousand units. Results of calculating the production function of calves for total sample of the study shows a statistical significant positive relationship between gross flesh and the quantity of each of green fodder, concentrated and dry, employment and the weight of the animal at the beginning of the grow-out period, as an increase in the amount of those variables respectively by 1% leads to an increase in the amount of output by about 0.055%, 0.692%, 0.161%, 0.008%, 0.037%. Results showing also that the marginal product of feed for total sample was about 7.79, 75.68, 17.39 kg live weight of feed green, concentrated, dry, respectively, means that the marginal product of concentrated feed greater than the marginal product of other feed refers to preferential use of concentrated feed production red meat. The optimum weight and maximizing profit weight for the total sample was about 445, 495 kg.   In light of results, the research recommends the following:   Expansion in the establishment of livestock production projects, and work to support and encourage breeders by increase loans, and to facilitate the procedures for obtaining it. 2. Increasing the concentrated feed production in deferent areas to be compatible with the geographical distribution of animal wealth.

Agricultural foreign trade represents an important place in the total foreign trade for its contribution to the amount of change in the deficit in the trade of agricultural balance plus or minus, and thus change the extent of the deficit in the trade balance, and foreign trade which reflects the production, consumption and investment variables through the evolution of exports and imports. The problem with research in the State to take a lot of policies that help the development of exports and reduce imports of agricultural ones especially, but he agricultural exports did not achieve its objective which reflects the weak economic performance in the trade deficit, and the goals of research identify the evolution of exports and imports of the subject of the study crops, and the study of the economic efficiency of the Egyptian agricultural foreign trade through the relative importance of exports and imports of agricultural goods through the international exchange rate, and estimate the total agricultural foreign trade efficiency, which Based on appreciation to a number of indicators including coverage rate, dependency ratio, the degree of economic participation. According to the results obtained, the average coverage of trade overall rate was about 43.86%, while the counterpart of agricultural trade amounted to about 41.2%, indicating a lack of total agricultural exports to the requirements of the total and agricultural development cover, also results indicate that the average economic dependency of the trade rate total amounted to about 56.92%, while the counterpart of agricultural trade amounted to about 15.3%, which indicates a decline of agricultural dependence on counterpart rate at the national level, and reached the total average degree of economic participation of trade about 40.39%, while the counterpart of agricultural trade amounted to about 43.7% which refers to the coverage of agricultural trade to the proportion of 92.5% of total trade, also indicate a net food balance and the ratio of exports of food imports to the existence of permanent disability in food balance statistics, has been the exchange rate decreased commodity crops study namely rice, wheat, maize, dry beans and potatoes to less than one is true, which means that the exchange rate in an invalid state and this would lower real income and the low level of well-being as a result of lower exports of these crops and this is due to the obstacles facing agricultural exports, and recommended research need to take care of software development and support services for agricultural exports from the structure key export and activating the agreements, and the expansion of agricultural projects that produce for export.

The main objective of this paper was to analyze the impact of government policies on fruit and vegetable sector  in 2003 and 2009 in terms of profitability, protection, efficiency, competitiveness and comparative advantages. The study depended on secondary data and information collected from relevant sources and references. The policy analysis matrix (PAM) adopted as an analytical model to achieve the study objective. Private profitability, social profitability, nominal protection coefficient on outputs, nominal protection coefficient on inputs, effective protection coefficient, domestic resources coefficient private cost ratio and subsidy ratio to producer were calculated for the crops under study. The study results show that fruit and vegetable sector was taxed for outputs and subsidized for inputs, the net effect of outputs taxation and inputs subsidies resulted in a net taxation on value added at varying degrees. Consequently, it could be concluded that, although the overall impact was negative and tending to be worse, but the study results indicate that there are still comparative advantages in fruit and vegetable crops production. The study recommended further vertical and horizontal expansion of fruits and vegetables, strengthening production infrastructures, and government should enact efficient policies that correct the distorting tradable - outputs policy.

The purpose of this study was to 1) assess the linkages in the New Valley’s Agricultural Innovation System (NVAIS) and 2) characterize the information structure underlying the system. Data were collected from 50 respondents represent the nine components of the studied system during the period from Feb. to Mar. 2015 using in-depth interviews. The graph theoretical technique (GTT) was used to assess the linkages and information structures in the studied system. The obtained results showed that NVAIS was not fully identified; however, 44 of a total 72 linkages only were identified, and have a density of 0.61. Only 14 linkages are established through specific linkage mechanisms so density declines to 0.19. The component "Observatory of Development and cooperatives (O)" is by far the main sender of information, followed by the component "Extension (E)" and "Higher Education (H)". The main receivers of information, is the component of "Farmers (F)". Components of "Research (R)" and "Policy (P)" have a special position in this system, being the most interactive components as it sends as much information as it receives from others. Components of Secondary agricultural schools (S) and Agricultural Credit (C) are candidates to reform because of they interacts other components at a low tone. The component of private input supply, marketing and processing (M) is isolated is needs to deal efforts on enhancing its interaction within other components of the system. Any interventions on the components of O or F will be reflected in all over the system because the first one is a dominant component while the second is subordinate. The intermediary institutions, O and E, should play a more active role in bringing together other components. Specifically, links between these components could be strengthened through policy dialogues where the O and E could pass information from S, F, M, and C to P, H and R; such transmission of information should help P, R and H reassess agricultural policy, research and education priorities

The main objectives of the research were to identify the size of wheat gap and find the appropriate solutions to apply  wheat self-sufficiency in the near future through  designing micro economic equilibrium model for wheat during the period (1995-2013) the model may identify the change in government revenues, the change in foreign exchange earnings and the rate of tariff,  the coefficient of the tariff and the change in surplus producers, the change in the surplus of consumers, efficiency indicators of a return or social loss in production and yield,  and social loss in consumption and total return.   The study predicted increasing in government loss about LE 13.287 billion in 2014 to about LE 20.11 billion, increasing in foreign exchange earnings of about LE 11.64 billion in 2014 to about 18.07 billion pounds, and it also expected to increase in the implicit tax (of the tariff rate) by the domestic producer of about 0.17 in 2014 to about 0.25. The study also predicted continuing socio loss in production to reach about LE 1.92 billion in 2020 because of continued rising in production costs, which is expected to reach about LE 5707 per acre in 2020 with increase ratio about 18.32% compared to 2013. It was also expected to continue growing consumer surplus to reach around LE 10.7 billion in 2020 and because of the government's continued support in the bread system.

Susceptibility of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera : Gelechiidae) larvae, pupae and adults to entomopathogenic nematode, Steirnernema carpocapsae and two fungal species; Beauveria bassiana and Metarhizium anisopliae was investigated under laboratory conditions. Applied concentrations against the last instar larvae and different ages of the pupae, using leaf and soil treatments, were 250, 500,1000 IJs/ml for the nematode and 108, 109,1010 spores/ml for the fungi. Soil applications of the nematode and fungi resulted to high mortality (100, 100 and 93.3%) of4thinstar larvae while low pupal mortality (46.7,30and 23.3% ),respectively. In leaf treatment a high level of larval mortality (93.3, 90 and 80%) was recorded revealing S. carpocapsae, B. bassiana and M. anisopliae, respectively. The present study also showed also susceptibility of Tuta absoluta adults to the three pathoens. The results demonstrated suitability of entomopathogenic nematode and fungi for controlling T. absoluta.

The main research objective was: to identify Knowledge and practice Gaps of fishermen in Lake Burullus regarding fishing Law Number (124) of 1983 through achieving objectives: idintifing the level of Knowledge and practice Gaps of fishermen, Identifying the relationship between Knowledge gaps and independent variables, Identifying the relationship between practice gaps and independent variables, Identifying the contact degree between fishermen and extension sources. To achieve the goals of research was selected a sample of 110 fishermen from a central Balteem and Sidi Salem at random from among fishermen obtaining fishermen card, data has been through a questionnaire to collect personal interview during the month of March 2013, and was used the following statistical methods: frequencies, percentages, and the coefficient of the simple Pearson correlation were used to analyze data.   The main results of the research were: medium  level of  Knowledge gaps  of all items (50 item)  studied law for (53.6%) respondents, while the  practice gaps were a medium for more than half of the respondents about (62.7%) respondents. There was a significant relationship between the Knowledge gaps and the following dependent variables: education, experiance, membership in organizations, frequencies on Urban centers, degree of exposure to media, degree of social participation and Knowledge sources. There was a significant relationship between the paractice gaps and the following dependent variables: Training, frequencies of Urban centers, membership in organizations, social participation, exposure to media, and Knowledge sources. There was low contact degree between fishermen and extension source (Extension Center, symposium, meetings and guidance on the Law No. 124 fishing, research institute, authority General wealth Fisheries Development and Cooperative Union of wealth water sources.

This study was carried out to investigate the effect of partial substitution (10 and 15%) of wheat flour by sorghum or chickpea flour on quality parameters of sponge cake and biscuit. Chickpea flour contained the highest percentage of protein, lipids, ash and crude fiber. Water absorption was increased by replacement of wheat flour with sorghum or chickpea flour. From the obtained data, it could be seen that the deleterious effect of adding sorghum flour to wheat flour on the rheological properties was more pronounced than that happened when chickpea flour was added. Cake prepared with sorghum flour had less pronounced improvements in its chemical composition rather than those of chickpea. With regard to volume and specific volume, cake prepared with 10% chickpea flour with or without cake improver recorded the highest values. Cake prepared by chickpea flour had no any unfavorable sensory change especially for the cake produced by cake improver.  Crude protein, lipids, ash and crude fiber contents were increased progressively in all biscuit samples with increasing of either the sorghum or chickpea flour levels. Also, there were no significant differences (P>0.05) between the thickness and spread ratio of control biscuit compared to that of sorghum or chickpea- wheat composite flour.  It is worth mentioning that the substitution of wheat flour with chickpea flour gave biscuit more sensory acceptable.

The need to increase the organic soil matter for sustainable production to match food security under semi-arid Egyptian conditions (high temperature, low preception, shortage of organic fertilizer etc..) led to looking for new sources of oragnic materials such as  modern composting technologies and increase the effeiency of recycling. The field experiment was carried out during the two winter successive seasons of 2011 and 2012 under open field conditions in protected cultivation site, Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Centre, Giza, Egypt. Peas (Pisum sativum), cv. Lincolin was used in this study. The study aimed to investigate the use of vermicompost as alternative organic fertilizer by different rates (15, 20 and 25 m3/feddan) compared to cattle manure (20 m3/feddan as a control) combained with two plant distances (30 and 50 cm) which  performed in split plot design. The obtained results indicate that increasing the rate of vermicompost from 15 to 25 m3/feddan led to increase the values of physical and chemical properties of both pea plants and yield characteristics. The highest vegetative growth characteristics were recorded by application rate of 25 m3/feddan combined with 50 cm plant distance followed by 20 m3/feddan combined with 30 cm compared to the other treatments. The application rate of vermicompost 25 m3/feddan combined with plant distance 30 cm gave the highest yield of peas per feddan. Concerning, the highest fruit quality parameters were estimated under application rate of vermicompost 20 m3/feddan combined with 50 cm. The recommended treatment under this study conditions was the use of vermicompost 25 m3/feddan combined with 30 cm followed by 20 m3/feddan combined with 30 cm of plant distance. The vermicomposting of organic wastes and applied it to the soil as an organic fertilizer instead of burial or inceneration led to store CO2 in the soil and decrease its emission.

The research estimated the efficiency of resource use among north western coast farmers in Marsa matrouh governorate using a sample of 200 respondents that were randomly selected; Interview schedules and structured questionnaires were administered to elicit information from the farmers. Data were analyzed using gross margin analysis, production, costs functions and resource use efficiency. The results for Tomato showed that, the regression analysis indicated that, R2 was highly significant at 1% level with the value of 90%. This implied that 90% of the total variations in Tomato  yield is explained by combine influence of all the explanatory variables (farm inputs) in the regression equation analysis, Gross margin analysis showed that farmers made profit (gross margin=  11810 LE / feddan). The resource use efficiency result showed that, the farm resources (cultivated area, organic manure, machines and labour) were under-utilized for Tomato production in the study area, The results for Cantaloupe showed that, The regression analysis indicated that,R2 was highly significant at 1% level with the value of 91%. This implied that 91% of the total variations in Cantaloupe yield is explained by combine influence of all the explanatory variables (farm inputs) in the regression equation analysis, Gross margin analysis showed that farmers made profit (gross margin = 15870 LE/feddan), the resource use efficiency result showed that two farm resources (cultivated area and labour )were under –utilized and one farm resource(N fertilizer) was over- utilized for Cantaloupe production in the study area.
