This work was divided into three process (Mincing fish, ensilaging minced material and making pellets containing ensilage minced material), respectively. In the first process the fish was minced at auger speed about 1.1 m/s and 4 mm die diameter to a material with bulk density of about 0.96 g/cm3. In the second process fish silage was prepared by mixing minced the fish with sufficient formic acid (3.5% by weight of 85% formic acid) to lower pH, and bacterial putrefaction was avoided, thus allowing the silage to be stored for several months. In the third process the evaluation was carried out on the machine using four different levels of material moisture content about (9.1, 12.6, 15.7 and 18.2% wet basis); four different die diameters [3, 4, 6 and 8 mm] and three levels of auger speeds [1.1, 1.7, and 2.3 m/s]. It was observed that the maximum value of pelletizing efficiency (ηp.),% were 87% which was achieved at moisture content (12.6%) ; auger speed (2.3 m/s) and die diameter (3 mm). Minimum value of Broken pellets (Bp) was 6.5% achieved at moisture content (12.6%); auger speed (2.3 m/s) and die diameter (3 mm). Maximum Pellating capacity (P), kg/h was 11.3 kg/h achieved at moisture content (18.2%); auger speed (2.3 m/s) and die diameter (8 mm).

The cropping pattern and crop evapotranspiration (ETc) of a region are mainly affected by the efficiency of the irrigation system. The objectives of this study were to investigate the impact of irrigation projects in North Delta on crop pattern and water consumption. Remote sensing (RS) and GIS techniques were used to evaluate crop pattern and ETc on El Moheet Canal, North Delta. This canal was subject to irrigation improvement practices (Mesqas and Marwas). This study was carried out during two summer growing seasons (2011, before the improvement and 2013, after the improvement). The obtained results showed that the pixels of the selected canal in both summer growing seasons were classified into 7 land uses (rice, cotton, seed melon, maize, open water, roads, and urban). Before the improvement, cotton was the dominant crop (42.7 %) followed by rice (33.3 %), seed melon (14.5%), and maize (9.5%). However, after the improvement, rice was the dominant crop (74.1%), followed by seed melon (10.7 %), cotton (9.2 %), and maize (6.0 %). The percentage of rice was strongly increased by about 113 % after the improvement. On the other hand, cotton, maize and seed melon were significantly decreased by about 79, 40 and 29 %, respectively, when compared with their areas before the improvement. It could be concluded from the Landsat data that the overall ETc was decreased after irrigation improvement in 2013 by about 4.3 %, whereas water requirement/ha was decreased by about 6.3 %. The obtained images also showed that the cultivated area was decreased from 2011 to 2013 by about 4.3 % due to urbanization. However, the non-cultivated area was increased by about 25 %. Crop distribution and the equity in water distribution along the branch canal were improved due to irrigation improvement. In conclusion, the improvement of the irrigation system saved irrigation water and raised the distribution equity of water.

This work investigated the potential of two concentrations of H2O2 (0.10 and 0.20 mM) applied through irrigation water, as a priming factor, in reducing the detrimental effects of soil salinity stress on wheat (Triticum aestivum L.). Two wheat genotypes, Gemaiza 9 (G9) as a moderately salt sensitive and Sakha 93 (S93) as a salt tolerant, were grown in pots containing a saline clay soil (ECe of 7.35 dS/m) under greenhouse conditions for 45 days. The obtained results showed that H2O2 application at 0.10 and 0.20 mM stimulated the germination of G9 genotype by 10 and 20%, respectively. Both fresh and dry shoot weights of G9 had increased by 9.92 and 7.70 and 8.52 and 8.2% for 0.1 and 0.2 mM H2O2 treated plants, respectively, as compared to control treatment. In contrast, In S93 genotype, negative effects on germination and fresh and dry weight were recorded. The irrigation with 0.1mM H2O2-treated water markedly increased the tillers to about 100% and 22.2% in G9 and S93, respectively, while 0.2mM H2O2 treatment increased the tillers number to 28.6% more in G9 and decreased it 16.7% in S93. Addition of 0.2 mM H2O2 had a negative effect on chlorophyll A content in both cultivars. In G9, chlorophyll B and carotene content were promoted particularly by 0.2mM H2O2. Significant decreases in Na+ content in both cultivars were observed with H2O2 application while potassium was not markedly affected. The K+/Na+ ratio of G9 was lower than that in S93 in all treatments and tended to increase in both genotypes with H2O2 applications. It can be conducted that application of H2O2 as a physiological priming factor may play a significant role in growth improvement of moderately salt sensitive wheat genotypes such as G9 through promotion of Chlorophyll B synthesis and reduction of Na+ content.

A study was carried out to test and evaluate the effect of high-temperature short time Infra-red heating process using a laboratory scale rotary dryer on drying and sterilization of high moisture rough rice and quality changes of the milled rice. The experimental treatments included five different levels of radiation intensity (0.973, 1.033, 1.093, 1.129 and 1.161kW/m²) and two different grain feed rates (2.5 and 3 Kg/patch). Two different drying models [the simple exponential model (Lewis, 1921) and Henderson and Pabis's model (1961)] were also examined for describing the drying data. The obtained results showed that:
1- Rapid moisture removal from rough rice was obvious particularly at higher levels of radiation intensity and lower grain feed rate.
2- Bulk temperature of the heat treated rice samples ranged from 39.1 to 133.3 ºC depending upon the radiation intensity, exposure time and grain feed rate.
3- Both studied models could satisfactorily describe the drying behavior of high moisture rough rice. However, the Lewis's model considered most proper for describing the drying behavior of rough rice due to simplicity of this model in calculations and analysis.
4- The high levels of infra-red radiation intensity reduced the fungal load in high moisture rough rice in an effective manner.
5- A reduction in broken percentage was observed as the radiation intensity decreased and grain feed rate increased.
6- Infra-red heat-treated rough rice yielded milled rice slightly yellowish in appearance in comparison with the sun dried sample.

The aim of this study was to evaluate two major types that used in modern pressurized irrigation systems (UPVC pipes and LDPE tubes made in Egypt). From all experiment steps data indicated that UPVC pipes fixed under soil surface (50, 100 cm depths), this type of pipes should be work under three forces, 1- Outcome pressure which deliver from systems pump, sometimes 50 meter head depended on systems design, 2 – Soil dry weight in range (1.5 kg sandy soil at 30 cm depth making a compact force for area below 50 mm diameter and 3 – Soil wet weight (soil + water (under saturated 1.9 kg wetted soil at 3o cm depth making a compact force for area below 50 mm diameter. All UPVC pipe pass in hydraulic test. To summarized the important part in UPVC pipes test. Hydraulic stander test should be include one extra recommendation that do the test of pressure procedure at one week; pipe should be test under three time of the nominal pressure. (Due to the force which face pipes when instillation). LDPE work in the face of heat transfer which coming from two places 1- Directly from sun in summer average temperature in the area of study were 48◦C. 2 – Heat transfer from soil and plant development in study area were in average, at summer at 10 cm depths was 28◦C. This mean that for testing and classification the LDPE tubes. The chemicals and heat test will be the most important part in LDPE classification; add to that analyzing the row materials for carbon black percentage and others materials which mainly had the negative effect on LDPE performance. For the effect of heat the tubes life time was very small less than 5 years. Therefore Egypt LDPE and UPVC product should be developed under the supervision of research centers and modified some part in stander of calcification.

The interest in alternative or renewable heat energy sources for greenhouses heating is currently high, due to the large burden of heating and the relatively high price of fossil fuels. The objective of this study is to analyse the thermal performance of hybrid system; solar energy and biomass greenhouse heating system (SBGHS). This study experimentally investigates the total burden of heating required for commercial greenhouse (1010.4 m3) heating by solar and biomass heat energy under the climatic conditions of eastern region of costal Delta, Egypt (latitude angle of 31º 02' 41" N, longitude angle of 31º 21' 55" E, and mean altitude above sea level of 6 m) during winter season of 2012-2013. The thermal performance analysis was experimentally determined, by measuring the temperature increase at various water inlet temperatures and intensity of solar radiation, under clear sky conditions. A complete solar heating system (six solar collectors and storage tank) was utilised for heating 1500 litres of solution (water and antifreeze). The daily average overall thermal efficiencies of the solar heating system and the storage system during the heating period, respectively, were 83.19% and 95.51%. Over 147 days heating season the solar heating system collected 9 222 kWh of which 8 830 kWh (31.788 GJ) of solar power was stored in the storage tank. It provided 27.47% of the total power required by the greenhouse. The biomass heating system added 145.136 kWh (522.490 MJ) of heat energy into the greenhouse which provided 66.37% of total power required for greenhouse heating. The hybrid heating system provided 205.206 kWh (93.84%) of the daily total heat energy required. The economics of such a system remains marginal at present power prices in Egypt, although changes in power costs may drastically alter the situation.

Field experiment was carried out at Maryout Experimental Station Farm, DesertResearchCenter during summer season 2007. The field experiment amid to study the impact of water stress levels of 100, 75 and 50 % from crop evapotranspiration, ETc during development, flowering and harvesting stages on some plant growth parameters and yield of tomatoes (Lycopersicon esculentum, mill., cultivator 888) in calcareous sandy clay loam soil. Drip and gated-pipe irrigation systems were used in this investigation. Generally, the obtained results revealed that the plant height values at harvesting growth stage under drip irrigation system were not significantly lower than those obtained under gated pipe irrigation system. The plant height values subjected to irrigation water stress levels 100, 75 and 50 % ETc during different growth stages were significantly decreased with increasing irrigation water stress levels under the studied irrigation systems. Tomatoes leaf water potential values,-kPa, at harvesting growth stage were significantly increased with increasing irrigation water stress levels subjected during different growth stages under studied irrigation systems. The fruit yield of tomatoes as affected by irrigation water stress levels subjected during different growth stages under drip irrigation system were significantly higher than that obtained under gated pipe irrigation system. Also, fruit yields of tomatoes were significantly decreased with increasing irrigation water stress levels under studied irrigation systems, especially at water stress level of 50 % ETc. For the fruit yield, the results showed that the flowering growth stage of tomatoes subjected to irrigation water stress levels is more sensitive than other growth stages under studied irrigation systems. Consequently, tomato plants subjected to water stress levels during flowering growth stage achieved the lowest net revenues and invested pound return.

This investigation was carried out to study the effect of P fertilizer sources i. e superphosphate (15.0 % soluble water P2O5)at 2.0 kg/tree, rock phosphate (6.25% total P2O5) at 4.8 kg/tree and without P addition under irrigation by acidic water at three levels from sulphoric acid i.e., without, 5 and 10 L/fed., on some vegetative growth and fruiting measurements as well as fruit and leaf nutrient content of peach trees Florida Prins’ cv. budded on Nemagard rootstock. The trees were 7 years old, grown at SobkVillage, Ashmoon, Monofia Governorate, Egypt, during 2012 and 2013 seasons. Obtained results reveal that the two tested P sources super or rock phosphate induced significant increases in vegetative growth, fruit yield and fruiting measurements as well as fruit and leaf nutrient content compared to without P addition (control) with superiority for superphosphate fertilizer which yielded more fruit yield / tree and yield/ fed., than rock phosphate in both seasons. Also, data show that the fruit quality including fruit physical properties and fruit chemical characteristics as well as fruit and leaf nutrient content were significantly improved as a result of the irrigation by acidic water compared to non acidic one. Furthermore, fruit yield quantity and quality as well as fruit and leaf nutrient composition of some macro elements (N, P and K) and some micro nutrients (Fe, Mn, Zn and Cu) were improved by adding sulphoric acid to irrigation water for both P fertilizer sources super or rock phosphate from the standpoint of statistic during both 2012 and 2013 seasons.

A field experiment was carried out at Kafr El-Hamam, Agricultural Research Station farm, Sharkia Governorate, Egypt, at lat. 30.35, long 31.30 and 13.00 m above the mean sea level during the two winter seasons, 2010/2011 and 2011/2012 to study the effect of different rates of inorganic NPK fertilizers i.e. 25, 50 and 75 % from the recommended dose (75, 15 and 24 kg N, P2O5 and K2O /fed., respectively) alone and/or companied with compost at the rate of 2 ton / fed., and/or humic acid at 6 kg /fed, as a soil application on bread wheat productivity, chemical composition and economic evaluation. Results can be summarized as follows: Generally, in most cases, application of compost with 75 % from the recommendation dose of inorganic NPK fertilizers achieved significant increases in yield and its components as well as chemical composition of wheat plant. The addition of inorganic NPK fertilizers at the recommended rate alone led to the highest significant increases in all yield components and yield as well as macronutrient content of grain, straw and biological yield. Protein percentage was higher by using inorganic NPK fertilizers at the recommendation rate and /or application of compost with 75 % from recommendation dose of inorganic NPK fertilizers. Meanwhile, application of humic acid individually or companied with 25 and 50% from recommended dose of NPK fertilizer gave significant decrease in all parameters in this study. By Calculating the net return of wheat per Feddan, the highest net return is achieved by using the treatment 100% recommended dose (RD), which estimated about 6214 LE in the first season, 5549 LE in the second season. Using humic acid alone achieved the lowest net return about 3616 and 3443 LE in the first and second season, respectively.

A field experiment was carried out during the two successive growing seasons of faba bean 2011/ 2012 and 2012/ 2013.
The aim of this investigation was to find out the impact of water deficit based on differentreference evapotranspiration( ETₒ) methods on water applied for faba bean crop.
The field trial was executed at Sakha Agricultural Research Station, which represents the conditions of North Nile Delta region. The field is clay in texture and furnished with drip irrigation system.
Main treatments were ET° methods;FAO Penman-Monteith, Ibrahim, Doorenbos- Pruitt and Modified Penman. While the subtreatmentswere levels of watering, 60%, 80% and 100% from irrigation water (IW.), IW= crop water needs (Etc) divided by Ei (Ei = irrigation efficiency = 0.85 for drip irrigation.
The main findings could be summarized as follows:
- Average seasonal irrigation water (IW) was ranged between 476.83and 696.41 m3 / fed.which recorded under 60% FAO penman- monteith and 100% modified Penman, respectively.
- Mean rainfall (RF) of the two seasons were 405.08 m3 / fed. (9.65 cm).
- Average of the total water applied (TWA) had the same trend of IW and ranged between 881.92 and 1101.50 m3 / fed. for the stated ETₒ methods, respectively.
- The contribution percentage of RF in WA was between 36.8 and 46% which resulted from 100% Modified Penman and the 60% FAO Penman- Monteith, respectively.
- Generaly, ET◦ methods can be arranged in inscending order regarding computation of IW as; FAO Penman- Monteith,Doorenbos&Pruit, Ibrahim and Modified Penman respectively.
Therefore,seasonal rate of water applied is ranged between 5.7 and 7.1 m3/ fed/ day.Out of them, almost half of it comes from rainfall.
So, more investigations should be carried out to verifying the role of rainfall in North Nile Delta in water applied for cultivated winter crops as wheat, barley and sugar beet under drip irrigation.
Since there is no significant difference in seed yield, then it is advisable to irrigate with 60% FAO Penman- Monteith or Ibrahim depending upon the availability of climatic elements.

A study was carried out to test and evaluate the use of infra-red radiation as heat energy source for drying lemon slices. A laboratory scale dryer was developed and tested at the laboratory of Agric. Eng. Dept. Fac. of Agric. Mansoura Univ. The experimental treatments included three different levels of radiation intensity (0.973, 1.093, and1.161 kW/m2), three different air temperatures (40, 50 and 60°C) and constant air velocity of 1 m/sec. The drying behavior was simulated using two different thin layer models (Lewis's and Henderson, and Pabis's). The studied models were compared with the obtained drying data, and the most suitable model for predicting the change in lemon moisture content during drying process was then assessed. Final quality of the dried lemons was also determined. The results show that, both studied models could describe the drying behavior of lemons satisfactorily. However, Lewis's model considered more proper for describing the drying behavior and predicting the changes in moisture content in terms of precision and application simplicity. The quality tests of the dried lemons showed that, radiation intensity of 0.973 kW/m2 with air temperature of 50°C recorded the best dried lemon quality in terms of higher retention of ascorbic acid (Vitamin C), citric acid and total soluble sugars.

Tow field experiments were carried out at Sakha Agricultural Research Station. Kafr El-Sheikh Government, during two successive seasons of 2010 / 11 and 2011 / 12. The objectives of this research where: (i) increasing wheat yield, (ii) decreasing the applied mineral fertilizer, and (iii) saving irrigation water. Experiments were arranged in split plot design with four replicates .The main plots were assigned to three irrigation intervals, irrigation every (20 (I1), 25 (I2) and 30 days (I3). The sub plots were assigned to three fertilization treatments of F1 (application of the recommended dose of mineral NPK fertilizer, 75, 30 and 48 unit / fed. for N, P and K, respectively). F2 (5 ton / fed. rice straw compost augmented with organic activator +75 % of the recommended mineral fert. (56, 22.5 and 36 unit /fed.NPK). F3 (10 ton /fed. rice straw compost augmented with organic activator + 50% of the recommended mineral fert. 37.5, 15 and 24 for N, P and K, respectively) The results can be summarized as follows: 1- Irrigation treatment I3 was the best treatment since it save water irrigation of about 10.8% (286 m3) and had no significant decrease in wheat grain yield compared to the traditional irrigation treatment (I2). 2- The highest wheat yield value of 3963.4 kg /fed. Was obtained with I2 F3 treatment, while the lowest one was with I1 F2 . 3- The highest straw yield was obtained by I2 F3 treatment which gave 5.35 ton/fed. 4- The highest protein percentage 11.31 % was obtained by I2 F3. 5- The highest irrigation water productivity (WIP) of 1.40 kg/m3 was obtained with I3 F3 treatment. 6- Water productivity values for I1, I2 and I3 were 1.27, 2.07 and 2.4 kg/m3, respectively indicating a superiority of I3 regime over the others. 7- The highest total organic carbon, organic matter, aggregation parameters and the lowest soil bulk density (1.161 kg/m3), which means the improvements of the soil structure and nutrient uptake, were obtained I2F3 treatment. 8- Therefore, irrigation wheat crop every 30 days with 10 ton rice straw + 50% recommended mineral fertilizer could be recommended for the management of wheat crop under the condition of the studied area.

A pot experiment was conducted at Agric. station of Faculty of Agric. Mansura University In 14 March; 2013 to study the effect of using some natural materials (phosphate rock and mineral sulfur ore) at two levels along with control treatment as fertilizers on eggplant growth, yield and some nutrients uptake.
Split-split complete block design was used with three replicates. The main treatments (3treatments) represent the studied natural materials and the sub-main treatments were arranged for theirs levels (two levels more than control) of the natural materials used. The sub-sub main treatments were oriented for bacterial treatments (with and without bacterial inoculation). The two levels of natural material used were 1.5 and 3 g pot-1 for each one and added to surface of soil and mixed with it before planting. Urea (46% N), superphosphate (15.5% P2O5) and potassium sulphate (50 % K2O5) fertilizers were applied at rates of 2.0; 1.5 and 0.5 g pot-1, respectively (200 kg urea fed-1,100 kg supper phosphate fed-1 and potassium sulphate 50 kg fed-1).
Data revealed that application of some natural materials as fertilizers (phosphate rock and mineral sulfer ore) to soil due to increase some growth parameters (length, diameter, fresh weight and dry weight of eggplant), increased NPK % in whole plant and fruit of eggplant, and increasedsome nutrient uptake both of eggplant at different periods and eggplant fruit at two collections.
