This study was carried out during 2012 and 2013 seasons in the Horticultural Research Station at Kanater El- Khairiya, Qualiobeya Governorate to throw light on the effect of different types and rates of fertilizer treatments on the rates of infestation of the cowpea plants, Vigna unguiculata L. by different pests Tetranychus urticae, T. cucurbitacearum (eggs and motile stages), Bemisia tabaci (eggs, nymphs, pupae & adults), Thrips tabaci (nymphs & adults) and green Jassids and on the resultant crop yield. Data revealed that treatment with NPK mixture recorded the highest infestation rate by T. urticae Koch, T.cucurbitacearum (Sayed) and T. tabaci in the two seasons, while the K2O fertilizer revealed the lowest infestation rates. Moreover, the N2 fertilizer recorded the highest infestation with whitefly and Jassids. The brown scale insects, Coccus hesperidium Linnaeus were firstly recorded in Egypt on cowpea plants but throughout the first season only. The mixture treatments resulted highest yield (2428.3 &2675 Kg./fed.) followed by Micro-element treatments (1500 &1658.3 Kg./fed.) then K2O fertilizer treatment (1416.7 & 1553.3 Kg. /fed.) in 2012 and 2013, respectively; being significantly higher than control which recorded (756.0 & 845.0 Kg. / fed.) for the two seasons.   However, the results showed a significant improvement in the uptake of NPK over the control, so it increased the production.

A green house experiment was carried out in two successive seasons on date Palm plantlets (Phoenix dactylifera L. cv. Bartomouda) from 2012 to 2013, to evaluated the effectiveness of different sources of nitrogen fertilizer at four treatments as (T2) 5 g/l ammonium sulfate 20 % (1 g nitrogen), (T3) 3 g/l potassium nitrate 33% (1 g nitrogen) and (T4) 2 g/l urea (46%) with the irrigation water one time/ week.The design of the experiment was randomized complete with three replicates. The results revealed that, plant height cm, leaves numbers, root length cm and numbers, and fresh and dry weights of leaves and roots were increasing highly significantly with 3 g/l of potassium nitrate graduated by 2 g/l urea and 5 g/l ammonium sulfate respectively at both seasons. Chlorophyll a, b and carotenoids contents showed significant rising with 3 g/l potassium nitrate. Greatest significant contents of indole and proline were obtained under T3 for two seasons. Leaves nitrogen content N was increased by 2 g/l urea in the two seasons; on the other hand, root nitrogen content was increased with treatment 3 g/l potassium nitrate, sequenced by T2 and T4 treatments. Leaves and roots phosphorus P content significantly raising under 3g/l potassium nitrate and 5 g/l ammonium sulfate for two seasons. In the presence of 5 g/l ammonium sulfate and 3 g/l potassium nitrate leaves and root potassium content K were largest at two seasons respectively. This research shows that the nitrogen formula as potassium nitrate > ammonium sulfate > urea were recommended to highly increasing growth of date palm plantlets in the green house.

A laboratory experiment was carried out to study the early growth response of 22 sugar beet (Beta vulgaris, L.) varieties to four salt concentrations of seawater i.e. 2000, 4000, 8000 and 16000 ppm. Germination and seedling growth traits (germination percentage (%), germination rate, seedling length (cm), seedling fresh weight (mg) and seedling vigor) were determined at the end of the experiment after 30 days from planting. The results showed that increasing the salinity level decreased the germination %, germination rate, seedling length, seedling fresh weight and seedling vigor of all sugar beet varieties under investigation to different extents. The results also clearly revealed that the response of the investigated varieties to salt concentrations was not the same, some varieties approved to be highly salt tolerant i.e. Soultan, Kawmira and Desprez; others were very sensitivity tolerant i.e. Helsiniki and LP16. However most of the investigated varieties were moderately salt tolerant. Results revealed clearly that the interaction effect between sugar beet varieties and salt concentrations was significant. This significant effect means that the tested varieties do not behave the same under the different levels of salinity stress.

Si application alleviates influence of some abiotic stresses on crop plants. Meanwhile, scarce information is avaiable about the significance of Si for helping the plants to overcome the injuries of N deficiency and herbicides pressure. Thus, two–year 2–field experiments were carried out in wheat. Experiment I involved three Si concentrations (Si0ppm, Si250ppm and Si500ppm) and two N levels(N100% and N50%). Experiment II examined four combinations of fenoxaprop–p–ethyl and Si: fenoxaprop–p–ethyl+Si250ppm and fenoxaprop–p–ethyl+Si500ppm (each either in sequence or in tank mixture), fenoxaprop–p–ethyl alone, hand weeding and weedy check. Under N deficiency (N50%), Si500ppm increased plant height as compared to the control. No significant differences in SPAD values were detected amongst Si concentrations under each of the two tested N levels. Si can partially alleviate negative N deficiency effect on wheat yield, causing its increase to level obtained under normal N supply. Si has no effect on weed biomass when applied with fenoxaprop–p–ethyl either in sequence or in tank mixing. The most promising treatment for maximizing wheat grain yield was the application of 100 kg N ha–1 (N50%) x fenoxaprop–p–ethyl+Si250ppm in sequence", which also, in the same time, means reducing both cost of crop production and environment pollution.

Oil crops occupies an important place in theEgyptian Agricultural Savin, come to their importance in the demand derived from the demand for the production of food plant oils , which form a pattern prevailed for the Egyptian consumers, some oil crops grown for the use of its products for the purposes of bilateral or trilateral. The peanut harvest of export crops important addition to being  one of the many crops to use and is characterized by high net yield of it compared to other crops. The research Targeting answer to previous questions and to try to develop solutions to overcome the problems that hinder the increased production of the crop peanuts in Egypt, especially as it crops which enjoys high quality in the territories does not bestow the cultivation of other field crops, as research aims to identify the most influential variable in response farmers to grow the crop and the study of functions and production costs for this crop. The results indicate that the average annual area planted peanuts estimated at about 137, 70 feddan during the period (2009-2012), the average productivity Per feddan  which is estimated at 17.59 Ardeb, while the average production of about 4352,20 million Ardeb for the same period referred to, Results also indicated response function width of the crop that the most important economic factors affecting the area planted peanuts in Egypt is the net yield per feddan of maize crop summer, summer tomatoes, sesame. The estimated production functions and costs for the three classes of possessory crop in the study sample. Finally, research suggests the following: 1- The development of varieties of high productivity copes with the Egyptian conditions with the application of Modern Technology in Agricultural Methods with the help of research organizations and Agricultural extension. 2- Work to increase the Organic fertilizer and reduce the amount of chemical fertilizer where it leads to increased production and reduced costs as indicated by the results of the study sample.  3- Encourage the establishment of factories involved in manufacturing main production areas such as the provinces of Nubaria and Lower Egypt (El-Beheira – El-Sharkeya - Ismailia) to encourage farmers to increase their production and supply at affordable prices.

This work aimed to study the effect of partial replacement of monosodium glutamate (MSG) by 5΄ inosine monophosphate (5΄-IMP) on the fertility of male rats after oral administration for 90 days. Before the biological treatment, a half amount of MSG as flavor enhancer in chicken burger was replaced by 5´IMP. The sensory assessment of cocked chicken burger confirmed that this used mixture (1:1 w/w) had a synergistic effect and led to improve the flavor intensity compared to that with MSG. Treatments were applied by stomach tube (mg/kg BW); (i) MSG, [60 for adult; 30 for weaned rats]; (ii) Mixture (1:1; w/w) of MSG and 5΄-IMP [30:30 for adults; 15:15 for weaned rats] and (iii) 5΄-IMP [30 for adult; 15 for weaned rats]. Body weight gain (BWG%) and weight of some reproductive organs including testes, prostate, cauda epididymes and seminal vesicles were measured. Serum testosterone and interstitial cell-stimulating hormone (ICSH) and seminal fructose content were assayed. Spermatozoa activity and the histology of reproductive organs were also studied in adult and weaned male rat groups. Severe negative effects on most studied parameters were demonstrated in MSG-groups, where the lowest fructose content in prostate, testosterone levels and spermatozoal activities were recorded. Reduction in the weight of cauda epididymes and testes was recorded in MSG-treated weaned rats. Histologically, all studied reproductive organs were dramatically affected by MSG-treatment. Considerable enhancements in the studied parameters and normal histological profiles were obtained due to the partial replacement of MSG by 5΄-IMP. In conclusion, 5΄-IMP has a potential protective effect against MSG-hazards in reproductive organs.

The study aimed at studying economic effects of global energy and food on the most important Egyptian imports. Descriptive and analytical statistical methods were used to achieve study objectives. Mathematical averages percentages and annual growth rates of variables under study were estimated. Expected values of imported food commodities using double exponential smoothing method was used. The study reached to some important conclusions, namely Global price and production of oil, coal, natural gas, ethanol and biodiesel have risen during the period 1996-2011. There were also a significant relationship between world prices and production of the above products. The price elasticities were about 0.089, 0.32, 0.174, 0.062, and 2.5 for these products respectively. The increase of oil price has an impact on food imports showing an increase of about 3.46% as a result of 10%of oil price increase. The study revealed that world oil price will be about $133.2/ a barrel in the year 2015 compared with $112.9/ barrel in the year 2011. It is therefore expected that value of food imports will increase to about $ 12.9 billion in the year 2015 compared to $ 10.6 billion in 2011.

Sugar beet is an important crop that helps in establishing integrated agricultural-industrial societies, especially in the new reclaimed areas, it contributes in many industries such as sugar industry, and highly-value animal feed resulting from processing waste. Sahl El Tina had been chosen as it is one of the most important of the recent reclamation and aquaculture region depending on water of Al Salam Canal. To achieve the target of increasing Production of sugar beet it became necessary to increase the efficient use of economic resources ,and to achieve this objective study Data Envelopment Analysis (DEA) Approach had been used in order to estimate the technical and economic efficiencies allowing to reduce production costs and increase revenue, and thus support the expansion in the cultivation of the crop. The sample have 3 categories according to the area of the farm, the first category consists of 3 feddans or less, second category is more than 3 feddans and less than 7 feddans, the third category is more than 7 feddans to 10 feddans. The goal of the sample was to compare the efficiency of these categories, and recommended the optimum size of the farm.

The potato plants (Solanum tuberosum L.) vs. valor were exposed to different levels of nitrogen fertilizer (60, 100, 140, 180 kg N/feddan (4200 m2)) and in-row plant spacing (12.5, 25 and 50 cm) for maximizing the yield production to match food security needs under climate change impacts on Delta region,  Egypt. The experiment was carried out during two growing seasons (2010/2011 and 2011/2012) in split plot design at El-Bossily Farm, Agricultural Research Center, El-Behira Governorate, Egypt. The vegetative growth characteristics and yield parameters were measured. The result of this study verified that increasing nitrogen level up to 180 kg N/feddan significantly increased the vegetative growth, total and marketable yields than the other N treatments. The in-row plant spacing 50 cm was significantly increased vegetative growth and yield (kg/plant), but the total yield (kg/m2) had different trend. The highest total yield /m2 was obtained by 12.5 cm treatment. The interaction effect of 180 kg/feddan of N and 12.5cm in-row plant spacing were increased the total tuber yield (kg/m2) significantly. In contrary, the best marketable yield (tubers > 35 mm) /m2 was obtained by 25 and 50 cm in-row plants.  This study was concluded that the best agronomic practices for potato production obtained by application 180 kg N/feddan of with in-row plant spacing 25 cm treatment. The economical consideration of the different treatments showed that the best total net income was obtained by 180 kg/feddan N with 50 cm in-row plant spacing.

Resulted in the opening of the Egyptian society to the outside world, and the work of many Egyptians in  the Petroleum States to increase the level of their income on the one hand and increasing population growth rates of  Egypt on the other hand which is reflected to increase the amounts and rates of food commodities consumption in general, and Edible Oil and fats, in particular, where The per capita consumption of Edible Oil about 15 kg/year, which gives an indication of the increased size of the food gap of Edible Oil where the problem was in that Edible Oil become one of the most important sources of the increase in the cost of Egyptian agricultural imports as a result of the application of the GATT as the cost of the Edible Oil imports by about 47 % of the increase in the total value of Egyptian agricultural imports posing a heavy burden on the balance of payments, and then the research aimed to analyze the impact of different variables to determine the most important determinants of consumption of Edible Oil and fats.           To be included in the Egyptian agricultural policy to help the decision-maker to take the necessary corrective actions about it. Where the study found several factors affecting the consumption of Edible Oil and fats can be limited to the most important are as follows: The per capita consumption of Edible Oil (of Human unit).  The per capita expenditure on Edible Oil, the effect of the price / income  ratio of group of Edible Oil and fats, the frequency of frying in the same oil, the function of the head of household, the average price of a kilogram of vegetable ghee, the volume of containers of Edible Oil, Types of pot keeping the oil after use, the use of oil in a frying more than one type of food, rising per capita income (Human Unit), increase the rate of  per capita consumption (of Human unit), the proliferation of fast food shops, as well as shops , beans and falafel, increasing individual consumption of fast food, especially after the revolution due length of waiting of individuals in the Egyptian street . The study pointed out many of the expectations and proposals could limit the most important are as follows: Increasing the area of ​​land cultivated oily crops, need to focus on projects in Toshka and the Qattara Depression and the cultivation of parts of the northern coast, the return to agricultural rotation system of enter including the Oileeds, restart Edible Oil factories with full capacity both in the stages of refining of raw Oil imported or Edible Oil extraction from locally grown Oileeds, rationalizing the use of Edible Oil in domestic consumption.
