2016
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.

The current study was performed to investigate effect of three water regimes as well as, three different soil conditioners on the yield and fruit quality of tomato. The studied water regimes were namely; 60, 80 and 100% of class A pan. However; the tested soil conditioners were “soil hanz”, “Olygo plus” and “Bioconditioner”. Impact of the two investigated factors was studied separately, as well as, the interaction. The experiment was carried out at El-Dolify Farm, Khatatba, Monofia Governorate during seasons of 2012/2013 and 2013/2014. Tomato hybrid Yara F1 was used in this investigation. The obtained results confirmed that, using the “Soil hanz” due to the significant increments in all tested parameters related to the yield and the fruit quality. Moreover; interaction between “Soil hanz” and any of the three tested water regimes was significantly the best in number of fruits per plant, average fruit weight, early, marketable and total yield. In addition; it was concluded from the results that; chemical properties of the tomato fruits were improved by applying the “Soil hanz”. Concerning the water use efficiency, it was found that, all of the tested soil conditioners resulted a significant effect related to water use efficiency compared to un-treated treatment (control). Whereas, irrigated the tomato plants under this experimental condition confirmed the validation of using the 80% irrigation regime for irrigation without significant losses in the crop yield.

2016
AL-Mansori Q.S. | Othman M. | AL-Wadeai M.
In a comprehensive study, soil surface (0-60cm) and subsurface (60-120cm) samples, (industrial- wastewater and wells water samples beside of plant samples (forest and wild shrubs) were collected from Almarawea’ah area, Al-houdiadah governorate. The objective of the study was to evaluate the environmental impact of wastewater that flow from food factory. The water is used for irrigating a silty loam soil and plants grown thereon which were evergreen trees (wind breaks) since 25 and 5 years ago (the first and second stages, respectively). Also, the analysis of chemical, physical, biological and microbial indicators was done. Obtained results showed that soil salinity was increased three times but sodium adsorption was increased 10 times as a result of using wastewater for irrigating the evergreen trees since 15 years ago where the EC and SAR were 0.115mS\cm and 1.3, respectively in the non-treated soil as compared with the treated one which were 0.37 mS\cm and 12.5 for EC and SAR, respectively. There was no significant impact for soil depth 0-60 and 60-120cm as well as for years of applications (5 and 25 years) on all the evaluated properties. However, organic matter, nitrogen, phosphorus, and iron contents in treated soil were slightly increased with no significant differences. On the contrary, potassium and manganese were significantly increased at 0.05 level as compared to non-treated one. Regarding to the plant analysis the obtained data showed that no significant differences between the concentration of the studied elements (N, P, K, Fe, and Mn) in leaves of trees (their local names are Muraimerah and Damas) and shrubs (Thomam and Abad). However, zinc concentration was high in shrub plants (2350.5 ppm) compared to trees (103.5 ppm) which indicated that shrub plants can collecte high levels of zinc ( zinc hyperaccumulatorplant). For water, comparison of samples collected from ground water wells (near and far) and wastewater samples collected morning and evening, the results indicated that using factory wastewater for irrigating trees to be used as wind breaks was suitable way to prevent expected environmental contamination and transmission of those contaminants to the ground water

2016
Fayyad S.
The objective of this research is to estimate price (direct and cross) and expenditure elasticities for major food commodities in Egypt. The food commodities are divided into six sub-models depending on the homogeneity within each group of commodities and the data availability quantities consumed and the corresponding retail prices for each individual item. Some commodities are aggregated in groups such as other beans, other vegetables, fruits(1), fruits(2) and oils. The Linear Almost Ideal Demand System (LAIDS) model is applied in estimating a system of demand equations for each group of food commodities. To avoid the invalid inference and spurious regression problems that may be created by non-stationary data series, the Fully Modified Least Squares (FMLS) estimator is utilized. The demand parameters satisfy the Engel aggregation, cournot aggregation, homogeneity and symmetry conditions. The results indicate that expenditure elasticities of the majority of food commodities/groups are less than the unity except fot the fruits2 (1.110), indicating necessity effects. This can be also interpreted as following the increasing of consumptions of these commodities is strongly connected with increasing of all income levels. The results also show that the own price elasticities for food commodities/groups are inelastic. For fruits 2, its inelastic own price elasticity still indicates that it tends to be very sensitive to price changes. The relative high cross price elasticities in all sub-models illustrate the strong substitute or complementary effects of the price change of one commodity one quantities consumed from other commodities in the same sub-models. Therefore, structural implications from the estimated elasticities are important. The estimated own and cross price and expenditure elasticities must be analyzed during the economic reform for better understanding all economic changes affecting prices as well as consumption and expenditures.

Heba Mohamed | Mowafi F.
This research aims to evaluate the competitiveness of rice exports during the period of (2002- 2013) using the market share index, the relative stability of exports coefficient, competitive price and market penetration coefficient to know causes of declining market shares for exports of Egyptian rice in the key markets and to suggest some methods to develop the Egyptian export policy for rice to increase competitiveness and improve export performance in the foreign markets. The results indicated that about 67.45% of the average amount of Egyptian rice exports is concentrated in five countries namely: Syria, Turkey, Libya, Jordan and the Sudan and about 32.55% is concentrated in Saudi Arabia, Belgium, Romania, the United States, Lebanon, Britain, the United Arab of Emirates, Kenya, Italy and other countries. Also, the results cleared a comparative advantage for Egyptian exports of rice in the world market. It was shown that each of the quantity, value and export price of rice is characterized by instability. The Egyptian rice has a competitive price advantage in India, Australia, Italy, the United States, China and Pakistan. The results showed that the penetration coefficient of the Egyptian exports of rice during the study period (2002- 2013) increases in the markets of the Sudan, Romania, Syria, Libya, Jordan and Lebanon. The study recommends the expansion of Egyptian rice to the markets of Jordan, Saudi Arabia and Kenya which is considered one of the promising markets. Establishing a system to follow up the export markets and gather accurate and immediate information about those markets and make it available in an easy and accessible way for the producers and exporters to identify the export opportunities and directing the production to the markets which receive a great amount of the Egyptian rice crop. Studying the competitive conditions of the Egyptian rice inside its main markets in order to increase the amount of exports.

2016
Shimaa Oraby | Elbordiny M. | Khaled M. | El-Neenah M.
Application of urea to agricultural soil may pollute the air environment due to ammonia (NH3) volatilization. Zeolite, Humate, biocher and biofertilizer may be used to control N losses resulting from urea transformation to NH3. A laboratory soil incubation experiment was conducted to determine the effects of zeolite, K-humate, biocher and biofertilizer on controlling NH3 losses out of applied urea. Calcareous soil sample from El-Nobaria area, Beheira Governorate was treated with different amendments and incubated under laboratory condition for 13 weeks. Results obtained showed that soil treated with urea in the presence of different amendments significantly reduced NH3 release from urea as compared to the control. During the first 80 days of the incubation ammonia losses were highest in control compared to soil treated with the different amendments. Biocher treatment showed the highest effect in reducing ammonia volatilization from calcareous soil. Therefore, treating calcareous soil with biocher and biofertilizer can decrease were losses as ammonia and increase nitrogen availability in soil, and hence reduces air pollution by ammonia.
