Six tomato cultivars were used. These cultivars were: (1) Castel Rock (U.S.A) (2) Edkawy (Egypt) (3) Super Marmand (France) (4) Flora-data (U.S.A) (5) B5357 (U.S.A) (6) Fline (France) crossed by using half diallel crosses mating design to obtain 15 crosses. All parent and crosses were evaluated through two seasons 2009and 2010 to evaluate heterosis for some characteristic of tomato.
The results showed that, 6F<sub>1</sub> hybrids for 15 ones gave no significant with positive values heterosis over the mid-parent for average of fruit weight in the first year. However, 3F<sub>1</sub> hybrids for 15 ones gave significant or highly significant with positive values heterosis over the mid-parents in the second year the largest value as a result of hybrid between 3x5 with value (42.3). While the result showed that significant or highly significant with positive values heterosis over the mid-parent for fruit firmness, the largest value (24.1).
The combined data over the two years showed that highly significant with positive values heterosis over the mid-parent for average of fruit weight trait ranged from (1.72% to 18.16%) came as a result between (2X3 and 3X5), fruit firmness trait ranged from (3.54% to 19.00%) came as a result between (1X4 and 2X3) respectively, total soluble solids trait ranged from (0.41% to 8.90%) came as a result between (1X4 and 4X6). while heterosis value over the better parents for average of fruit weight ranged from (0.76 to 4.06%) for the crosses (4x6 and 1x4) respectively. Also, fruit firmness ranged from (1.88% to 16.35%) for the crosses (2x4 and 2x3).

This study was carried out at laboratory and greenhouse of Agricultural Botany Department, Faculty of Agriculture, KafrelsheikhUniversity during two winter seasons of 2009 and 2010. The main objective of this study is: Effect of two treatment of bacterial endophytes strains <em>Azotobacter chrocooccum</em> (E1) and <em>Pseudomonas </em>sp. (E2) individually whether as grains soaking and foliar application on growth and yield parameters of two wheat plants (<em>Triticum aestivum </em>L.) cultivars (Sakha 93 and Gmiza 9) grown under three levels of irrigation water deficit stress 75, 50 and 25 % field capacity. Growth parameters that were take into account were plant height, number of leaf/plant, flag leaf area, fresh and dry weight/plant. In addition, wheat yield parameters included spike length and dry weight, number of spikelets/spike and grains number/spike. Generally, irrigation water deficit have an undesirable effect on growth and yield parameters of the tested wheat cultivars. Application of <em>Azotobacter chrocooccum</em> (E1) and <em>Pseudomonas</em> sp. (E2) strains individually were carried out by spray foliar and grains soaking treatments increased the tested vegetative and yield growth parameters for two cultivars, after 40, 70 and 130 days from planting compared with untreated plant. Entophytic bacterial strains treatments play an important role in protection of wheat plants against the adverse effects of drought stress, improve water productivity and will lead to significant water savings for irrigation sector.

The present investigation was conducted using six flax genotypes with their 15 F<sub>2</sub> crosses grown under two environments {normal soil (E<sub>1</sub>= Kafr El-Hamam – Shrkia Governorate) and saline soil (E<sub>2</sub>= Tag El-Ezz,- El Dakahlia Governorate)} to determine the combining ability and gene action of some agronomic flax characters in these entries (parents and their crosses). In 2009/10 season, the six parents { P<sub>1</sub>= Giza 8, P<sub>2</sub> (S.402/1) , P<sub>3</sub> (S.420/140/5/11), P<sub>4</sub> (S.421/43/14/7), P<sub>5</sub> (S.533/39/5/3) and P<sub>6</sub> (Daniela)} as well as their 15 progenies were sown in first week of November to evaluated in a randomized complete block design with three replicates at the two above- mentioned locations.
High ratio of GCA/SCA revealed that additive played greater role than non-additive genetic effects in the inheritance of straw weight and its components as well as seed weight, 1000-seed weight and number of seeds/capsule under the two environments and combined analysis. On the other hand, both additive and non-additive types of gene action were involved in the inheritance of number of capsules/plant. Mean squares of interaction between environment and both types of combining ability for most studied traits revealed that the magnitude of both additive and non-additive types of gene action varied from environment to another. Whereas the non-additive genetic effects are more influenced by saline environment than additive effects in each of straw weight, plant height, technical stem length, seed weight, 1000-seed weight and number of seeds per capsule. While, additive gene effects were much more influenced by saline environment than non-additive effects for number of capsules per plant. P<sub>5</sub>(S.533/39/5/3) exhibited good general combining ability effects for straw weight per plant and its two important components; plant height and technical stem length in addition P<sub>2 </sub>for both seed weight and 1000-seed weight as well as P<sub>1 </sub>for 1000-seed weight under the two environments and combined data. For Sij effects, one cross (P<sub>5</sub>´P<sub>6</sub>) which exhibited positive significant SCA effects for straw weight per plant and its components as well as seed weight per plant and number of capsules per plant in addition three crosses (P<sub>1</sub>xP<sub>3</sub>, P<sub>1</sub>xP<sub>6</sub> and P<sub>4</sub>xP<sub>6</sub>) for 1000-seed weight under the two environments and combined analysis. Therefore, these crosses are suitable in breeding program for increasing the previous characters. The correlation between cross means and their SCA values was significant and positive for straw weight and its components as well as seed yield and its two important components, number of capsules per plant and 1000-seed weight indicating that high performing crosses were high specific combinations.

Nitrogen (N) fertilization plays a central role for improving yield in different vegetable crops and high N assimilation is desired to produce higher fruit yield. Several studies showed that salicylic acid (SA) application increases plant growth and productivity, but no attempts have been made to investigate the interaction effects of SA and N-nutrition. The aim of this study was to analyze the effects of different N-rates and SA concentrations, and their interaction on plant growth, photosynthetic pigments and fruit yield. Field experiments were carried out during two consecutive growing seasons under Egyptian conditions using different combinations of N and SA rates. Plant biomass and fruit yield were increased linearly in response to N addition from 0.0 to 90 kg/fed. in both years, however, this effect was true for photosynthetic pigments, especially chlorophyll a, b and total chlorophyll, in the second year of cultivation. Salicylic acid application showed mostly a significant increase in the previous traits under all N-rates. Carotenoids content in leaves was not affected significantly by N and SA in the first sampling date, however, in the second date it affected negatively by N fertilizer. The above mentioned results revealed a synergism between N fertilizer and SA application. This study showed that SA addition increased plant growth and yield mainly by increasing the N recovery from the soil.

The experiment was carried out during the two seasons of 2008 and 2009 on broccoli F<sub>1</sub> Hybrid Sakura to study the effect of two packaging materials and modified atmosphere packaging (MAP) on quality attributes of broccoli florets stored at 0<sup>o</sup>C and 95% RH for 16 days.
Broccoli florets packed in polypropylene film showed the highest intensities of freshness, greenness, and compactness and had less off-odor as compared with those stored in polyethylene bags. There were no differences in weight loss between broccoli florets stored in the different packaging materials.
Florets packed in active MAP retained their weight during storage as compared to those in passive MAP. The optimum gas composition of MAP tests for maintaining quality of broccoli florets during storage was 5% O<sub>2</sub> + 10% Co<sub>2</sub>.
Off-odor was not observed in broccoli florets packed in polypropylene film and exposed to 5% O<sub>2</sub> + 5% Co<sub>2</sub>, while at 5% O<sub>2</sub> + 10% Co<sub>2</sub> gave a slight off-odor at the end of storage with non significant differences between them.
Packing broccoli florets packed in polypropylene film and exposing to active MAP (5% O<sub>2</sub> + 10% Co<sub>2</sub>) was the most effective treatment for reducing weight loss and color change and maintaining high content of chlorophyll and gave florets with good appearance for 16 days at 0<sup>o</sup>C and 95% RH.

This work was conducted in the experimental farm of Mallawy Agricultural Research Station, Agricultural Research Center, Egypt, during the two successive winter seasons of 2009/2010 and 2010 /2011 to compare the performance of 10 populations of advanced generations of faba bean in two successive cycles of selection under free infested with broomrape (<em>Orobanche crenata</em>) and compare the productivity of free fields to that resulted from highly infested fields. Ten populations already evaluated revealed from crosses between five faba bean parents of Giza-843, Giza-429, (57/721/94) Line-3, Line-4 (664/689/94) and Giza 2 and continued to F5 and F6 selected generations. Two cycles of selection were done on 10 F5 and F6 populations that exceeded Giza-843 in seed yield per plant and the results indicated surpassing 6 out of the 10 populations of the F5 and F6 selected families that permit to high performance populations of faba bean. The most outstanding yielding ability of faba bean populations were Giza-843 × G-429, Giza-843 × Line 3, Giza-843 × Line 4, Giza-843 × Giza-2, G-429 × Line 3 and Line 4 × Giza-2 that gave promise for high yield and make a good chance for high yield faba bean cultivars in the future. The results of F6 families were similar to those of F5 families where the performance of faba bean plants under heavily infested fields revealed selected populations of high seed yield that surpassed that of Giza-843 and that was represented in the first five families already mentioned and these six families gave parallel performance under free infested fields exceeded family Giza-429 × Line 4. The performance under both types of fields was clear from the highly decreased values of yield of faba bean plants grown under heavily infested fields.
Then it is rather grow faba bean in free fields than in heavily infested fields in order to attain high productivity of this important crop.

This experiment was conducted at the Experimental Station of Vegetable and Floriculture Department, Faculty of Agriculture, Mansoura University under green house conditions during the two successive seasons of 2010 and 2011 to study the effect of different culture media and levels of mineral NPK fertilization and their interaction on vegetative growth and chemical composition of <em>Ficus benjamina</em> and <em>Ficus hawaii</em> transplants grown in pots.
Four culture media were tested (peat, peat moss + perlite, peat moss + sand and peat moss + perlite +sand). Each medium received three levels of NPK fertilizer (0, 2 or 4 g/pot).
Regarding the effect of culture media, the obtained results indicated that <em>Ficus benjamina</em> transplants grown in the medium of peat moss+perlite+sand induced the highest values for plant height (cm), number of leaves per plant and number of branches per plant in the first season, while in the second one, the values of these characters were higher when the transplants grown in the medium of peat and perlite. NPK concentrations (%) in the leaves increased in both seasons when <em>F. benjamina</em> transplants grown in the culture medium of peat moss+perlite+sand, while the highest values of total chlorophyll content (mg/g fresh weight) in leaves were recorded in the transplants grown in the medium of peat and sand in both seasons. For <em>Ficus hawaii</em>, the highest data for plant height (cm), number of leaves and number of branches per plant were recorded when the transplants were grown in the culture medium of peat+perlite+sand in the first season, while in the second one, the best results in plant height and number of leaves/plant were recorded by the transplants grown in peat+sand medium, while the medium of peat+perlite gave the highest number of branches/plant. The highest values of N, P and K (%) as well as total chlorophyll content were recorded when <em>F. hawaii</em> transplants grown in the culture medium of peat moss+perlite+sand in both seasons.
Concerning the effect of NPK fertilization on <em>F. benjamina</em> transplants, data showed that in the first season the addition of NPK at the rate of 2 g/pot increased plant height and number of leaves and branches per plant. In the second season, the previous parameters were the highest by the application of 4 g/pot. For <em>Ficus hawaii</em>, the highest value for plant height was obtained when 4 g/pot NPK was applied, while fertilization with 2 g/pot was more effective in increasing number of leaves and branches per plant in the first season. In the second one the application of 4 g/pot recorded the highest values in all vegetative measurements. The highest values of N, P and K (%) as well as total chlorophyll content (mg/g fresh weight) were belonged to <em>F. benjamina</em> and <em>F. hawaii</em> transplants fertilized with 4 g/pot in both seasons.
The interaction between culture media and NPK treatments were the most effective on the previous parameters. Vegetative growth characters (expressed as plant height, number of leaves and branches per plant) of <em>F. benjamina</em> transplants were improved as a result for planting in peat moss+perlite+sand medium and fertilization with 2 g/pot NPK in the first season, while in the second one that was true when the transplants were planted in peat+perlite medium and received 4 g/pot NPK. In case of<em> Ficus hawaii</em>, the transplants grown in peat moss+perlite+sand medium gave the best results in plant height, number of leaves and branches per plant when received 4 g/pot NPK in the first season. In the second one, the transplants fertilized with 4 g/pot NPK showed the best results in plant height and number of leaves per plant when grown in peat moss+sand medium and the highest value in number of branches per plant when grown in peat moss+perlite+sand medium. The superiority in N, P and K percentages as well as total chlorophyll content (mg/g fresh weight) for both plant species in both seasons was for the interaction treatment of moss+perlite+sand culture medium plus fertilization with 4 g/pot NPK.
According to the aforementioned results, it could be recommended under conditions of the present research to use peat moss+perlite+sand (1:1:1 by volume) as a culture medium for <em>Ficus benjamina</em> and <em>Ficus hawaii</em> transplants in combination with NPK fertilizer (20:20:20) at the rate of 2 or 4 g/plant.

Two field experiments were conducted at El-Serw Agricultural Research Station, Damietta Governorate, during 2008/2009 and 2009/2010 seasons, to study the effect of farmyard manure (0, 10, 20 and 30 m<sup>3</sup>/fad), plant densities (33600, 42000 and 56000 plant/fad), four biofertilizer treatments (without treated, inoculation seeds with Cerialine, Netrobine at 450 g/fad and 90 kg N/fad as a mineral fertilizer)and their interactions on growth and yield of sugar beet .
The obtained results indicated that farmyard manure had a significant effect on average values of root fresh weight, sucrose %, purity % and yields of top, root and sugar/fad in both seasons. Increasing farmyard manure rate up to 30 m<sup>3</sup>/fad significantly increased root fresh weight, top yield/fad, root yield/fad as well as sugar yield/fad but, decreased sucrose % and purity % as compared to control (without added farmyard manure) in both seasons<strong>. </strong>
Plant density significantly affected all studied traits in both seasons. The highest plant density 56000 plant/fad gave the highest values of sucrose %, purity %, top yield /fad, root yield /fad and sugar yield/fad, but it gave the lowest root fresh weight. On the contrary, the heaviest root was recorded with the lowest plant density 33600 plant/fad as compared with other studied plant densities in 2008/2009 and 2009/2010 seasons.
Results indicated that fertilization treatments had a significant effect on all studied characters in both seasons. Applying nitrogen as a mineral fertilizer at a rate of 90 kg N/fad gave the highest values of root fresh weight, top yield/fad, root yield/fad and sugar yield/fad as compared with all other fertilization treatment, in 2008/2009 and 2009/2010 seasons. In this connection, cerialine biofertilizer followed the mineral nitrogen of the mentioned previously traits.
The interaction between farmyard manure rates and plant densities, the interaction between farmyard manure rates and biofertilization treatments and the interaction between plant densities and biofertilization treatments were significantly affected all studied traits in both seasons. The interaction effect among farmyard manure, plant density and fertilization treatments was significant on all studied characters in both seasons. Plants received 30 m<sup>3</sup>/fad farmyard manure at the highest plant density 56000 plant/fad and fertilized by 90 kg N/fad gave the highest top yield/fad 33.65 and 39.28 tons, root yield/fad 40.76 and 39.20 tons as well as sugar yield/fad 7.11 and 6.75 tons compared to all other this interaction treatments in 2008/2009 and 2009/2010 seasons, respectively.
Generally, it could be recommended that applied farmyard manure at the rate of 30 m<sup>3</sup>/fad for sugar beet plants sown at plant density of 56000 plant/fad, and fertilized by 90 kg N/fad gave the highest root and sugar yield/fad at North Delta, Damietta Governorate, Egypt

Wadi El-Hawashiya is one of the most important wadis of the Eastern Desert of Egypt that occupies a specific position in the Gulf of Suez area. Annually, it receives 10 mm rainfall adding to annual storms creating flash floods that put the wadi on attention focus for sustainable development. The present investigation aims at recognition, identification of floristic components and evaluation of the nutritive value of vegetation as an ecophysiological adaptation towards the accident environmental stresses, through clarifying the chemical composition of the dominant species during different successive seasons. Phytosociologically, the results indicated that the co-dominant <em>Zilla spinosa</em>-<em>Zgophyllum coccineum</em> community type dominated the upstream portion of the wadi bed, while <em>Artemisia herba-alba</em> and <em>Zilla spinosa</em> communities dominated two different sites at the midstream portion. The surveyed plants were classified according to their palatability into three groups; high palatable, low palatable and unpalatable. Also, the results showed that the variations in edaphic factors, especially soil texture, salinity, moisture contents and sharp-ct sloping at the wadi bed, play important roles in the distribution and growth of plants and in accumulation of osmotically active constituents inside the plant tissues. Ultimately, results of the present work indicated that there is an intimate relationship between accumulation of K<sup>+</sup> ions and the formation and account anion of carbohydrates.

The current study was conducted at tissue culture laboratory of Vegetable and Floriculture Department, Faculty of Agriculture, Mansoura University during the period from 2010 – 2012. A protocol is described for rapid and large-scale propagation of the sweet potato (<em>Ipomoea batatas)</em> by <em>in vitro</em> culture of shoot tips or nodal segments as explants. The best sterilization method for the explants was observed by using Hg Cl<sub>2</sub> at 0.1 % for 14minutes and70%ethanol for 30 seconds. Nodal segments were found to be more efficient than shoot tips for sweet potato shoots regeneration on MS medium (Murashig and skoog, 1962) supplemented with 2ip at 4 mg/l + 0.5 mg/l GA<sub>3</sub>. Adding activated charcoal (AC) to the culture medium at 2 mg/l was the most effective treatment to avoid of browning phenomenon occurrence (0.00%). Among the five different cytokinins Thidiazuron (TDZ), kinetin (kin), 6-benzyl aminopurine (BAP), - N6-(2-isopentenyl) adenine 2ip and phloroglycenol (PG) and four concentrations of each, TDZ at 1.00 mg/l gave the best results for shoots multiplication. Concerning the rooting stage, Indole-3-acetic acid (IAA) at 2.0 mg/l clearly in henced roots development. Mixture of peat moss :vermiculite : perlite (1:1:1 v/v/v ) recorded the highest results for survived plantlets in terms of survival percentage,

Two field experiments were carried out during the two successive seasons of 2009 and 2010 at south El-Tahrir Research Station, (Ali Moubarak) Horticulture Research Institute to study the response of cassava plants to the combination between three rates of water requirements and compost manure at three rates of application. Obtained results were as follows:
1- The longest plants, highest leaves and largest length and diameter of branches as well as the heaviest total cassava yield and its best physical (tuber length and diameter) and chemical characters expresed as N,P and K contents of tuber tissues were recorded with cassava plants received 35 ton/fed. of compost followed in descending order by the addition of compost manure at 30 ton/fed. and the finally the application of 25 ton/fed. of compost manure.
2- The medium and high level of irrigation water (100 and 120%) encouraged the vegetative growth of cassava plants expresed as number of leaves, stem length, number of later branches and branches diameter and total tuber yield and the highest values of physical and chemical tuber quality i.e. tuber length and diameter as well as N,P and K contents of tuber tissues.
3- In spite of the non significant effect of the interaction of water requirements and the levels of compost manure application in the two seasons.

Heavy metals may be introduced in agricultural soil by many sources, one of which is sewage sludge application as a fertilizer. Heavy metals in polluted soil can negatively affect plant growth and productivity. Aiming at exploring means to alleviate heavy metals stress on soybean plant, the present study was performed with the objective to test the alleviating effect of ascorbic acid, salicylic acid, yeast extract, thyme oil as well as inoculation with arbuscular mycorrhizal fungi on soybean plants challenged with either cadmium, cobalt or sewage sludge. Results indicated that though all had beneficial effect manifested by maintaining yield and reducing its content from heavy metals as well as elevating stress-related metabolites, especially phenols, application of thyme oil or yeast extract and inoculation with arbuscular mycorrhizal fungi were the most effective and are recommended to be employed to mitigate heavy metals stress on soybean in heavy metals-affected soils.

An efficient protocol for both development of aseptic tissue cultures and shoots regeneration for <em>Cynara scolymus </em>L. cv. Herious was established by using <em>in vitro</em> micropropagation technique. Meristem tips of good young offshoots from selected globe artichoke plants were used as explants. Dipping shoot tips (1-2 cm length) in 70% ethanol for 5-10 seconds followed by 0.1% HgCl<sub>2</sub> (W/v) for 2 minutes and then in 3% sodium hypochlorite for 20 minutes was the most effective sterilizing and disinfectant treatment for surviving the majority of meristem tip cultures after 5 weeks of culturing. In the establishment stage, adding 0.5 mg thidiazuron (TDZ) /l to MS basal medium gave the best values for both shoots and leaves number but registered middle values for average shoots length compared to the other treatments. Concerning the multiplication stage, among the different cytokinin types and concentrations used such as 2iP, BA and Kin (at 0.5, 2.5 and 5.0 mg /l for each) and TDZ (at 0.05, 0.5 and 1.0 mg /l) in addition to control treatment (hormone-free MS medium), 2iP with all concentrations recorded the highest values in this respect in terms of shoots and leaves number and average shoots length. The multiplication rate of proliferated globe artichoke shoots and average shoots length were markedly increased with increasing subcultures number on MS basal medium augmented with 5.0 mg 2iP /l + 1.0 mg IAA /l till the fourth subculture then declined thereafter during the fifth one.

Application of the optimal seed rate and adequate amount of nitrogen fertilizer led to increase productivity of hybrid rice under broadcast seed condition. Two field experiments were carried out during 2010 and 2011 rice growing seasons at the Experimental Farm of Rice Research and Training Center, Sakha, Kafr El-Sheikh, Egypt to study the response of Egyptian hybrid rice 1 to four seed rates, i.e. 5, 7.5, 10 and 12.5 kg seed fed<sup>-1</sup> and five nitrogen levels, viz 0, 23, 46, 69 and 92 kg N fed<sup>-1</sup> under broadcast seeded-rice. The results of this study can be concluded as follows: the seed rate of 7.5 kg seed fed<sup>-1 </sup>produced the highest mean values of chlorophyll content, dry matter accumulation and leaf area index (LAI (at 65 days after sowing (DAS), while after harvesting also, gave the highest mean values of number of filled grains panicle-<sup>1</sup> and grain yield tons fed<sup> -1</sup>. The plots which planted with 10 kg seed fed<sup>-1 </sup>recorded the highest mean values of No. of tillers, No. of panicles m<sup>-2 </sup>without significant differences with the rate of 7.5 kg seeds fed<sup>-1</sup>, but the heaviest 1000 grain and panicle grain weight. Also, data revealed that Egyptian hybrid rice 1 response positively to application of nitrogen levels up to 92 kg N fed<sup>-1</sup>, which recorded the highest values of all traits. The highest grain yield was obtained when rice was grown at seed rate 7.5kg seeds fed<sup>-1</sup>and fertilized with 92kg Nfed<sup>-1</sup>.
