Abdalla B. | Abdelhafez M. | Thanaa Mohammed | Aza Badr | El-Shahat M.
The current study aimed to investigate the effect of microbiological treatment on improving the nutritive value of corn silage as animal feed. Dried whole corn plants were prepared and two ground silos (0.5 ton each) wereused for ensiling whole corn silage and inoculated by bacterial inoculant (containing Lactobacillus plantarum and Entrococcus faecium) at the recommended rate of 1/2g bacterial inoculants/liter of water/ton of fresh whole corn silage. The ensiling period lasted for 50 days. The criteria of response were determined by: the quality of treated corn silage, chemical characteristics and performance of rams, nutrients digestibility and nitrogen balance. Results for treated and untreated silage, respectively, showed that the silage had pH 3.71 and 3.69, Total Volatile Fatty Acids (TVFA) were 2.48 and 1.98 mmol/100ml, and NH3-N values were 6.1% and 6.41% (on dry matter basis). The values of organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE), nitrogen free extract (NFE) and ash content on dry matter basis, however, were very close in the two rations. There were no significant differences between the two rations for the dry matter (DM). The value of CF digestibility was not significantly different from that in treated corn silage, while ration contents of treated corn silage were significantly higher in OM, CP, NFE and EE digestibility than the untreated corn silage. Recorded values for total digestible nutrients (TDN) and starch value (SV) of rations of treated corn silage were significantly higher than those of untreated corn silage being 52.64 and 63.37 vs. 43.53 and 56.09%, respectively. The digestible crude protein (DCP) values were (7.43%) for ration of treated corn silage by 5.96% for the ration of untreated corn silage.

EL-Mamlouk A.H. | Refaai M. | Abdelaziz M.R.A.
Superior grapevines fertilized with compost, biofertilizers namely (Bacillus megatherium, Bacillus curculanse and Azotoacter Chroococcum), humic acid and two slow release fertilizers namely ( rock phosphate and feldspar ) as a partial replacement of mineral N fertilizers during 2013 and 2014 seasons. Using all substitutes of mineral N fertilizers was favourable than using mineral N alone in enhancing all growth characters, total chlorophylls, nutrients, yield and berries characteristics. Both nitrite and nitrate in the juice were greatly declined in all N management treatments that included the application of all N sources. The best results with regards to yield and berries characteristics of Superior seedless grapevines were recorded on vines that received 60g N, 60g P and 120g K/ vine/ year ( mineral sources) plus compost II ( 40% cattle manure + 60% rice straw ) at 16 kg./ vine+ the three biofertilizers namely Bacillus megatheium, Bacillus circulanse and Azotobacter chroococcum + humic acid each at 10ml./ vine/ year.

Abd El-Rady F. | Nagwa Rasmy | Nessrien Yasin | Abd El-Razik M. | Fahmy A.
For improving the safety of filling cream, the Hazard Analysis Critical Control Points (HACCP) system was applied during different preparation process. Different biological, chemical, and physical hazards that may exist in every preparing step of filling cream were identified and control measures were used for controlling those identified hazards. Dried milk powder was identified as high potential hazard raw materials contaminated with pathogenic bacteria e.g. S. aureus and Salmonella sp. Whipping step in preparing filling cream was identified as critical control point. For improving the safety of preparing filling cream system, different control measures including, thermal processing (pasteurization), addition of natural preservatives (lemongrass oil and herbs of cinnamon, clove and anise) and reduction of pH (fruit pulps of strawberry, apricots and apple) were established. Different applied control measures could be used for improving the safety of prepared filling cream where different investigated microbiological criteria were reduced to acceptable levels especially pathogenic bacteria. In addition, different HACCP principles as the critical control points, critical limits, monitoring, corrective measures, verifications and records were established. Implementing the HACCP system during preparing filling cream can effectively ensure safety of this product and other food products contained filling cram especially bakeries.

This investigation was conducted for two successive seasons (2013 and 2014) in a private vineyard located at 64 Km of Cairo-Alexandria desert road to study the possibility of using organic products to reduce powdery mildew, which it is reflect in reducing yield and fruit quality of King Ruby grapevines. The chosen vines were ten-years-old, grown in a sandy loam soil, spaced at 1.5 X 3.0 meters apart and irrigated by the drip irrigation system, trained to bilateral cordon with spur pruning, and trellised by the "Y" shape system. The vines were pruned during the last week of January with bud load of (60buds/vine). Application of different biocontrol agents Trichoderma harziamum, Trichoderma viride, Bacillus subtilis as well as blight stop a commercial biocide which contains different isolates of Trichoderma forms in Arabic gum and potassium soap) were obtained kindly from central lab. of organic agriculture, ARC. Giza, in an attempt reduces powdery mildew of the plants. The results showed that all vital bioagents treatments significantly were reduced the powdery mildew disease compared with micron sulphur and control in both season. However, spraying mixture of Trichoderma harziamum + Trichoderma viride and blight stop gave the least disease incidence and severity which it is reflect to increase yield, achieve the best physical characteristics of bunches as well as improving the physical and chemical properties of berries.

Identifying the development relation between different sectors in the entire Egyptian economy (2006/2013) through using of social accounting matrix , containing in addition to data on the inputs and outputs of the productive branches in the economy, but among other things also data concerning the distribution of the various kinds of factor incomes over institutional groups and classes, the expenditures made by these groups on different types of commodities, and the savings and investment made by them. The research showed the existence of permanent deficit representing by 1.5% annually which grown especially after the revolution of January 2011, so there where retreat of the rate of growth. So, it was suggested to do more as possible dis aggregate into socio- economic groups. It will be reasonable to dis-aggregate households into socio-economic group which mean In this case do more to the level and pattern of consumption, expenditure and income distribution, that is to say to dis-aggregate Egypt society as follow: - Regional differences (urban and rural-household). - Egypt level of the head of the household. - Access to productive forms of material wealth particularly agriculture and manufacturing wealth. So The foregoing demonstrated the importance of studying the changes in a macro variables which form the economic relations of social accounting matrix annually and can identify deficiencies and take all measures to avoid such shortcomings even took those incremental trend variables where this may include increasing volatility of investments requires more caution in directing those investments among different sectors, or they may be growing incrementally as imports that requires imports to be more identifying from the point of view. The nature and priorities of rationalization of imports and its component so all variables must be viewed in the same way to reach ultimately aims to increase incoming, reduce expenses and create surplus that support development.

Alaa Elsabea
Farmland infringement for the purpose of construction has become a serious problem in Egypt that negatively affects the average per capita of arable land and soil fertility in Egypt. On the other hand, this situation negatively affects Egypt's self-sufficiency rates of agricultural commodities, agricultural income, and employment in rural areas. However, farmland infringement is completely forbidden by the Egyptian agricultural legislation. In this regard, the current research aims at evaluating the impact of the Geographic and placement impact on Farmland infringement in Egypt during the period (2005-2010). This study recommend the importance of reduce farmland infringement in different Geographic places, to increase the Egyptian agricultural production, raise Egypt's self-sufficiency rates of agricultural commodities, and reduce the deficit in agricultural trade balance, and reduce the problem of unemployment in rural areas. Moreover, the current study used descriptive and statistical analysis to achieve its goals. The main results of this research showed that the total area of agricultural land that had been infringed during the period (2005-2010) reached about 4031 feddans during the period (1993 –1995), increased during the period before revolution (1996 2010-) to 28788 feddans and increased more after revolution during the period 2011- 2014 to ( 38046) feddans. By calculated the total yearly average of farmland infringement in Egypt, the result show that it was about 30.8 feddans during the period (1993 –1995), increased during the period before revolution (1996 2010-) to 43.3 feddans and reduced after revolution as a total to 34.8 feddans as a result of reducing the rate of farmland infringement in the civilization governorate by intensive security power. On the other hand the farmland infringement in all other this rate had increased in all geographic placements in Egypt. Where the yearly rate of farmland infringement in Delta of Egypt, Meddle Egypt and upper. Egypt reach about (43.1, 49.5, 41.2) feddans respectively before revolution, increased after revolution to (712.1, 405.8, 354.5) feddans respectively. It is clear that the delta Egypt has the highest yearly rate of farmland infringement, so it is important to control this rate in future. Besides, the results showed that the most important reasons behind farmland infringement by construction in Egypt are the dummy variable representing the Geographic and placement for the governorates’ and time. The economic model shows the increase of yearly average of total farmland infringement by about 74.4 feddans and the result was significant at the level of significance 1%. Moreover the yearly average of farmland infringement for Delta of Egypt, Meddle Egypt and upper Egypt by about (287.9, 101.7, 95.4( respectively. On the other hand, by using the dummy variable of piecewise to describe the situation after and before revolution in the different geographic and placement of governorates the results show the increase of the farmland infringement after revolution in delta of Egypt from 1136.4 to 2704.3 feddans and the results was accepted significantly at the level of 1%. The results show also the increase of the farmland infringement after revolution in middle of Egypt from 206.7 to 492 feddans and the results was accepted significantly at the level of 1%. Furthermore the results show the increase of the farmland infringement after revolution in Upper Egypt from 254.2 to 605.1 feddans and the results was accepted significantly at the level of 1%. However, the results showed that the farmland infringement after revolution in Egyptian civilization governorates decreased as a results of strong security from -34.5 to -82 feddans and the results was accepted significantly at the level of 1%. Finally, the research recommends strengthening the importance of protected the Egyptian agricultural land specially in the highest geographic and placement governorates especially in delta of Egypt, middle and upper of Egypt by achieving the balance of investment between all these geographic and placement governorates and establishment the necessary desert villages to meet the needs of Rural households.

Although Asparagus (Asparagus officinalis L.) is chiefly known as a vegetable herb, little information about the botanical characteristics of such plant are available. Therefore, it is aimed in this study to bring light more information about the morphological, anatomical and some important chemical contents of vegetative and reproductive organs of the plant, throughout the consecutive stages of its entire life span under the local conditions. Seeds of Asparagus (cv. Mary Washington 500 W) were sown 2nd Feb. 2013. The field experiment was carried out at the Experimental and Research Station of Fac. of Agric., Cairo Univ., Giza, Egypt during the two successive growing seasons 2013 and 2014. Asparagus is a herbaceous, perennial plant that grows up to 1.5- 2 m height. The plant posses aerial stems (ferns) and much- branched feathery foliage. The leaves are triangular scales like, 3-7 mm in length. The cladodes (modified stems) arise in the axis of scale leaves . Cladodes are found in fascicles (3-6) on each node. The flowers are bell- shaped, greenish –white to yellowish, 4.5-6.5mm long, with 6- tepals,single or in clusters of 2-3. Anatomical studies were carried out for various organs of Asparagus plant including, apex of the aerial stem, visible internode below shoot apex, median portion of the aerial stem, the cladode , median portion of spear, scale - like leaf, rhizome, adventitious root. The major chemical metabolites contents of spear were determined.
