The dissipation of oxamyl, emamectin benzoate, and imidacloprid pesticide residues in tomato fruits and their effect on its lycopene content were evaluated. The tested pesticides were applied according to the recommendation of the Egyptian Ministry of Agriculture for emamectin benzoate (Pasha EC 1.9%, 250 cm3/fedan), imidacloprid (Confidente SC 35%, 75 cm3/100L), and oxamyl (Vydate SL 24%, 3L/fedan). Pesticide residues in tomato fruits were analyzed using recently developed QuEChERS method coupled with HPLC. Recovery assays confirmed the validity and efficiency of QuEChERS with 101, 93, and 110% recovery for oxamyl, emamectin benzoate, and imidacloprid, respectively. The half-life (t1/2) values for oxamyl, emamectin benzoate, and imidacloprid in tomato fruits were 2.88, 3.12, and 3.46 days, respectively. After 12 days from application, the residues of oxamyl, emamectin benzoate, and imidacloprid in tomato fruits reached 1.0, 0.09, and 0.23 mg/kg, respectively. However, except imidacloprid, these residue values of oxamyl and emamectin benzoate were still above the maximal residue limit (MRL). In addition, the cumulative effects of imidacloprid and emamectin benzoate have significant inhibitory effects on the lycopene content compared to untreated tomato fruits.

The present work was carried out in the Flower and Ornamental Plants Research Gardens, Faculty ofAgriculture Alexandria University, Egypt during the years of 2010 and 2011. Two local cultivars of of Perlgonium zonale L. and Santolina chamaecyparissus L. were used in this work to study the effect of planting density on the parameters that affected their potential landscape uses.Different planting density were used i.e. 6, 9, 12 and 15 plants/m2 for Pelargonium and 9, 12, 15 and 18 plants/m2 for Santolina. Results indicated that increasing the planting density (plants/m2) significantly increased only plant height. However, it decreased the plant diameter, leaf area, number of main branches/plant and slightly decreased plant condition (appearance, health, beauty, ornamental value and function) for Pelarganium and Santolina plants as well. From the previous results it is recommended to usePelargonium plants with an average diameter of 28 cm and at a rate of 15 plants/m2, while for Santolina plant it is needed to start with a suitable plant (its diameter > 15 cm) at rate between 15– 18 plants/m2 to obtain good landscaping potential and ornamental value.

Two separate pot experiments was conducted to evaluate the nematicidal activity of the alginate controlled release (CR) formulations of aldicarb (FA3, FA6 and FA9) and cadusafos (FC3, FC6 and FC9) versus the corresponding granule formulations against the root-knot nematode Meloidogyne incognita infecting tomato under green house conditions. The results indicated that all the tested formulations significantly reduced the number of galls, egg masses, and 2nd juveniles in the soil as compared with the untreated pots (control). On the other hand, the CR formulations of aldicarb and cadusafos could be reduced the galls, egg masses, and 2nd juveniles in soil significantly compared with their granular formulations. The percentage reduction in nematode galls for all the CR formulations of aldicarb and cadusafos were ranged from (95.1% to 96.04%) and (87.1% to 88.03%) for aldicarb and cadusafos, respectively. Whereas, the lowest percentage of reduction of the number of tomato galls was recorded with aldicarb and cadusafos granule formulation (61.3% and 66.71%), respectively. Also, the maximum reduction of the number of 2nd juveniles in the soil was achieved by the FA3 (86.73%) and FC3 (89.08%), while for its corresponding granule was (59.05% and 46.23%). It could be noted that the nematicidal efficacy of the CR formulations against M. incognita reached to approximately 1.77 folds by FA3 and 1.93 folds by FC3 comparable to the commercial formulations. The possible effects of different aldicarb formulations residues on the chemical constituents of tomato fruits were determined and recorded at the end of the experiment (72 days). The results obtained indicating that all the aldicarb and cadusafos formulations had significantly decreased of the b-carotene, lycopene, and ascorbic acid content of tomato fruits comparable to the untreated pots. No significant differences were found between all the aldicarb formulations and the control on the percentage of the total soluble solid (T.S.S.) whereas there were significantly increased in the percentage of T.S.S. of tomato plant treated with the CR cadusafos formulations. The FA3 and FC3 could be applied on tomato plant to control nematode with a minimum side effect on the quality control parameters such as lycopene, T.S.S. and ascorbic acid content of tomato juice compared with the commercial formulations.

A common belief is that plant roots absorb cations from soil solution experiments with corn (Zea mays L.) using K/Rb ratio to evaluate the source of K and Rb absorbed indicated that the plant roots absorbed these ions in the ratio of exchangeable K and Rb. The objective of this research was to study the source of K and Rb absorbed from soil by Jerusalem artichoke (Helianthus tuberosus L.) roots since they do not have root hairs and this may influence the uptake mechanism. Jerusalem artichoke absorbed K/Rb with a ratio which was intermediate between the ratio of exchangeable K and Rb and the ratio of these cations in solutions. In comparison with corn, Jerusalem artichoke absorbed K at one-third the rate, but absorbed water three times faster so that mass flow contributed a greater proportion of K absorbed by Jerusalem artichoke than that by corn. This, rather than differences in root hairs may be the reason for the observed differences in K uptake between corn and Jerusalem artichoke.

Two experiments were carried out during of 2012 and 2013 seasons under controlled macroclimate of greenhouses on sweet pepper plant (Capsicum annuum L.) CV. Spanish to investigate the effects of two bio-fertilizer types, i.e., microbin and blue-green algae and different levels of nitrogen, i.e., 0, 60, 120 and 180 kg N/fed on plant growth, yield and its components as well as N, P and K concentrations (%) in both foliage and pepper fruits. The interaction between the two factors was also studied.
Treating pepper plants with bio-fertilizer, i.e., microbin or blue-green algae significantly increased foliage fresh and dry weights, plants height, fruit yield/plant and average fruit weight as well as nitrogen concentration in both foliage and fruits in the two seasons. On the other hand, number of main stems and fruits dry weight were not significantly affected by bio-fertilizer in both seasons. In addition the number of fruits/plant was not significantly affected in the first season only.
Increasing nitrogen level up to 120 kg N/fed led to significant increases in plant height, fresh and dry weights of foliage/plant, fruit yield/plant as well as average fruit weight in the two seasons. Also, nitrogen had positive effect on nitrogen concentrations percentage in both foliage and fruits in the two seasons.
The interaction between bio-fertilizer and nitrogen levels exerted significant effects on fruit yield/plant, number of fruits/plant and nitrogen concentrations in both foliage and fruits in the two seasons. Treating pepper plants with bio-fertilizer at the rate of 2 kg/greenhouse and 2 liter/greenhouse, intervals in addition to 60 kg N/fed gave the highest total fruit yield/plant.

A field experiment was initiated in 2010 to compare the effects of liquid ammonium polyphosphate (APP) and granular diammonium phosphate (DAP) on growth, nutrient content, and yield of Jerusalem artichoke (Helianthus tuberosus L.). Two sites on a coarse-textured Inceptisol with markedly different cropping histories were selected, one with 6 ppm P, the other with >201 ppm P extractable with 0.05 N HCl+0.025N H2SO4.Fertilizers were banded at P rates of 0, 24,48, and 71 kg/Fed. at the low P site, and 0, 10, and 20 kg/Fed. at the high P site. At the low P site tuber yields and tissue P concentrations were lower in case of (APP) than that of (DAP), while tissue concentrations of Ca, Mg, Mn, and Zn were higher in case of (APP). At the high P site, tuber yield and top dry weight were not affected by P source, but tissue Ca and Mg contents were higher and tissue P was lower with (APP). In 2011 and 2012, (DAP) and(APP) were applied at a rate of 24 kg P/Fed. at the low P site. Tissue levels of P again were lower while these of Ca, Mg, Mn, and Zn were higher with (APP) for the two years. Tuber yields were lower with (APP) in 2012.
In 2010, (DAP) and(APP) were applied at the high P site at the same rates used in 2010. Yields were unaffected by P source but tissue P content was lower but tissue Zn content was higher in case of (APP). Extractable P levels in soil samples taken after harvest were higher in 2010 for (APP) treatment .With time, extractable P declined for both sources, and by the following crop season, there were no differences in extractable P between P source. Extractable P again was higher in 2012 where (APP) had been applied. The results showed that availability of P fertilizer for summer planted Jerusalem artichoke was less with(APP) than that of (DAP). Less P was found in tops of Jerusalem artichoke with (APP) regardless of the level of available soil P. Tuber yields, however, were less affected by P source, and the data suggest that most years tuber yields will not be different with these two sources except on soil with very low levels of available P. Application of (APP) also resulted in increased uptake of Ca, Mg, Mn, and Zn by Jerusalem artichoke.

The present study was designed to investigate the response of Ocimum basilicum L. plants to four rates of NPK (0, 50, 75 and 100% of recommended) and four treatments of active dry yeast (ADY) as biofertilizer (0, 2, 4, and 6 g l-1) and their combinations. The recommended dose of NPK (100%) was 11.11, 7.41 and 3.70 g plant-1 of ammonium sulphate (20.5% N), calcium super phosphate (15.5 P2O5) and potassium sulphate (48.5% K2O), respectively.
The experiment was carried out during the growing seasons of 2012 and 2013 at Agric. Research Station, Alex. Univ., Egypt. The result showed that 100% of NPK combined with ADY at 4 and/ or 6 g l-1 gave the highest value of vegetative growth characters (plant height, number of branches, number of leaves, leaf area and leaves dry weight) in the two cuts of the two seasons as well as the greatest content of total chlorophyll, oil percentage and linalool, eucalyptol percentage in the oil of basil leaves. The highest significant increase in the Estragol and trans-4-methoxycinamaldehyde percentage in the oil of basil leaves were obtained by using 50 or 75% dose of NPK in combination with 4g l-1 of ADY.

An experimental study was conducted to determine the performance of two evaporative cooling systems, as well as the gradients of temperature and humidity along a greenhouse. The first system was the cooling unit, (CU) compared with the traditional fan-pad one, (F-P). The cooling unit was connected with two perforated ducts inside the greenhouse. The air temperatures and relative humidities on the longitudinal axis were measured outside and just after leaving the media and at each one meter from the pad media. They were also, measured in the traverse axis parallel to the pad media at distances 0.5, 1.5, 2.5 and 3.5 m from the edge of the greenhouse. A steady state mathematical model was modified to predict the greenhouse air temperature according to the state of the air just leaving the cooling media.
According to the experimental results, the non-uniform temperature changes were observed along the greenhouses for the two systems. The average temperatures of the CU greenhouse were 27.9, 30.4, 33.2, 29.1 and 27.9 oC for outside ambient temperatures of 28.7, 32.4, 35.4, 32.1 and 29.4 oC, respectively. The ranges of temperature gradient inside the CU greenhouse were 2.1, 2.1, 2.2, 2.2, and 2.1 oC. While in the F-P greenhouse, they were 5.9, 7.4, 8.2, 5.9 and 6.1 oC for the same ambient temperatures. The average air temperature entering to greenhouse was approximately 6.82 and 7.09 ºC lower than the outside air temperature for CU and F-P systems. The greenhouse of CU system was higher in the relative humidity than F-P one. The average relative humidities were 69.0 and 61.8% for the CU and F-P greenhouses, respectively, with increase percent 12.38%. The averages CU efficiencies were 77.55% and 74.79% in the first and second days, respectively, while they were 72.97% and 70.19% for the same days for F-P system. Consequently, the CU system was averagely more efficient than the F-P system by 6.29% and 6.58%. The water flow rate of the two systems to permit optimum wetness and air saturation were 5.6 and 6.5 L/min for the CU and F-P evaporative cooling systems, respectively. The saving percentage in water circulation was 16.1% for the CU system. The total yield per plant was 6.24 and 5.48 kg/plant for the CU and F-P systems, respectively. The CU system increased the yield per plant with 13.82% over the F-P system.

Fishing craft (Method) is one of the most important elements of capitalistic elements which use in the production process of fisheries sector, every fishnet has a different way to work according to the type of the boat used, whether it was automatic or sailing boat. Also, the location and depth of fishing and the materials used in manufactured determine the type of fish catch whether it was demersal or pelagic fishes. The most important legal prevailing crafts in Alexandria Governorate Mediterranean Sea Fisheries are; (1) Trawling craft, (2) Purse seine craft, (3) Shore or Beach craft, (4) Trammel craft, (5) Long Line craft, (6) Karkaba craft. The mechanical boats work with one of these crafts (Trawling, Purse seine, Trammel, Long Line, and Karkaba), which contribute around 66.2% of total average fishing effort in Alexandria Governorate Mediterranean Sea Fisheries during the period (2000-2011), but fishing boats licensed to work with Shore or Beach craft with second-degree or third-degree, Where the fishing effort is estimated private Shore or Beach craft and other coastal crafts approximately 33.8% of average total fishing effort in these fisheries. The catch composition of fish depend on the using net, and the productivity of fish trip of those crafts approximately about 8.5 tones, 903.8 kg, 666.0 kg, 465.3 kg, 474 kg in Trawling, Purse seine, Trammel, Long Line, and Karkaba respectively (2013). The result of operating project & feasibility study evaluation shows that these crafts economically feasible in the short and also long term. Economic efficiency of those crafts varies from one to another, the highest Economic efficiency in trammel craft while the lowest in big Trawling craft. The small units of fish production achieve the economic and productivity efficiency higher than their counterparts in present and future, which encourages the investment in small units of fish production (Less than 200 HP), so the Internal rate of return (IRR) of the small production units are higher than their counterparts in big production units, which is higher than its guaranteed counterparts on governmental bonds (16%).

The problem of this research has been identified as the growing gap of sugar despite the increase achieved in the production of sugar and the increase in the number of plants of sugar beet in recent years. Therefore, the main objective of this research is to study and analyze some economic variables associated with the production, consumption and sugar industry in Egypt. The results of this research show that the area of sugar cane and sugar beet crops during the period (1997- 2012), has increased by 1.74, 22.3 thousand feddan respectively, while production has increased by 90.1, 446.1 thousand tons respectively. This means an increase in the total amount of sugar output of both crops by 1517.9 thousand tons. Economic indicators for sugar cane and sugar beet showed an increase in the profitability per Egyptian pound invested in the season by about 12.7%, as well as the measure of the ratio of total revenue to the costs by about 5.6%. Efficiency indicators per unit of water show that sugar beet is higher than sugar cane by about 117.3%. The result shows that the total sugar production is increasing annually at significant statistically rate of 54.4 thousand tons. National consumption of sugar has increased by 95.1 thousand tons; sugar is growing annually by 40.8 thousand tons, and average per capita consumption increased by 0.74 kg/year. Results show that the most important factors affecting sugar gap in Egypt are per capita consumption of sugar, the number of Population, and total amount of sugar. Due to necessity of sugar and lack of production, too much consumption, the researchers have tried to propose different scenarios to maintain self- sufficiency in sugar at least in short run, upon calculations it seems possible in short run, while in long- run the only possible way to achieve self- sufficiency is to expand cultivated area of sugar beet and improve the Efficiency of both agriculture and Industry.
