Water shortage in rice cultivation area in Egypt pushed rice farmer to use poor quality water in rice irrigation. Using the correct nitrogen form with the proper rate might be coping with the condition and possible heavy metals in such water. Two field experiments were conducted in 2010 and 2011 seasons at The Farm of Sakha Agriculture Research Station, Kafr-El Sheikh Governorate, Egypt. The soil texture was clayey. EC was 1.5dSm<sup>-1</sup>. The study aimed to find out the effect of various nitrogen forms; Urea, ammonium nitrate and ammonium sulfate with varying nitrogen levels of 0, 109, 146 and 219 kg N ha<sup>-1</sup> on Nickel (Ni), Cadmium (Cd) and Lead (Pb) concentrations in soil, rice straw and rice grain as well as yield and yield components of Giza 178 rice variety under poor quality water .The chemical analysis of irrigation water was as following, Ni 0.28, 0.27, Cd 0.15, 0.17 Pb 0.34, 0.36 mg kg<sup>-1</sup>, ECw 2.66, 2.71 and pH 8.15 , 8.2 in the first and second seasons, receptively. Results indicated that the tested nitrogen forms and rate significantly affected the concentration of above-mentioned heavy metals, yield and yield components in both seasons. Ammonium sulfate was more efficient than other two nitrogen forms in minimizing heavy metals concentration in soil or rice plants and in enhancing yield and yield components under such poor quality water. The worst nitrogen form was ammonium nitrate regarding heavy metals concentration in plant or soil as well as yield and yield components of rice. Increasing nitrogen rate negatively affected the availability of heavy metals in soil, and their concentration in straw and grain of rice in both seasons. Furthermore, the increase nitrogen level (up to 146 kg ha<sup>-1</sup>) significantly improved yield and yield components of rice in both seasons.

This investigation was carried out during 2007-2008 to determine whether the selected chemical agents can be used to improve the post-harvest quality of snapdragon (<em>Antirrhinum majus</em>, L. cv. Riesen Vorbote) spikes, freshly cut flowering spikes were placed in glass bottles containing 100 ml of preservative solutions [distilled water or 8-hydroxyquinoline sulfate (8-HQS) at 200ppm or silver thiosulfate (STS) at 0.2mM] with or without sucrose at 20 g/L. Compared to the control, all treatments improved the quality and vase life of the flowers. Vase solutions containing 8-HQS plus sucrose was the most effective in promoting water uptake, percentage of maximum increase of spikes fresh weight so that the vase life of cut spikes extended to 18 and 16 days during the first and second seasons, respectively. The results indicated that using 200ppm 8-HQS combined with 20 g/Lsucrose has the potential to be used as a commercial cut flower preservative solution for delaying flower senescence, prolonging the vase life and enhancing post- harvest quality of snapdragon cut flowers.

Field experiments were carried out during 2009 and 2010 seasons at three Field Crops Research Stations of (Ismaelia, Sids and New valley). Five different seeding rates were used i.e. 25, 30, 35, 40 and 45 kg/fed and two row spacing i.e. , 30 and 60 cm. Split plot design in three replications are used.
The results indicated that sowing at seeding rate of 35 kg/fed with 30 cm row spacing significantly increased all agronomic characters over all cuts and recorded 42.64 t/fed and 8.49 t/fed for total fresh and dry yield, and considered as the best recommended treatment to cowpea under New valley conditions. At Ismaelia conditions, the higher yield was obtained from sowing at seeding rate 45 kg /fed and row spacing of 30 and of 60 cm. Sowing at seeding rate 25 kg/fed with row spacing 30 cm was a perfect treatment for increasing yield. Over two cuts of Sids conditions sowing at seeding rate 30 kg /fed and row spacing 60 cm recorded the best result 15.63, 9.65 t/fed of fresh yield and 1.94, 1.04 t.fed<sup>-1</sup> of dry yield for the first and second cuts.
The results showed insignificant regression of total fresh yield related to the control was recorded R<sup>2</sup> = 0.2895, R<sup>2</sup> = 0.1888 and R<sup>2</sup> = 0.5822 for NewValley, Ismaelia and Sids, respectively. Chemical composition recorded means of 26.3% soluble carbohydrate, 17.4% crude protein, 21.8% crude fiber and 13.0% ash. Increasing in seeding rates amplified the competition among plants for environmental factors.

This study was carried out during two successive seasons (2010 and 2011) on fourteen years old Banati guava trees (<em>Psidium guajava</em> L.), grown in sandy soil in the South of Tahrir region at Aly Mubarak Research Station. GA3 at 300 or 400 and 500 ppm was sprayed once time at full bloom, hand pollination with pollens from Malizi and Gizi guava trees for Banati guava trees as well as branches bending were carried out. The obtained results revealed that most treatments especially those included GA3 sprays improved the yield and fruit quality. However data proved that GA3 sprays at 400 ppm were more effective in increasing number of fruit set/ meter and fruit set and subsequently improved the yield as well as the physical fruit characteristics. Hand pollination with pollens from Malizi guava tree for Banati guava trees significantly increased total acidity and Vitamin C. Branches bending had the highest percentage of total sugars. So, spraying 400 ppm GA3 one time at full bloom was the promising treatment for increasing productivity of low yield Banati guava trees grown under sandy soil condition.

This investigation included four major parts (starting stage, multiplication stage, callus induction stage and rooting stage) as well as Acclimatization stage. The data of this study revealed that in starting stage, MS medium supplemented with 3 mg/l IBA or with 2 mg/l Kin + 2 mg/l IBA gave the best results of survival percentage. The highest number of shoots obtained by explanted cultured on MS medium supplemented with 2 mg/l BA. The tallest shoots were obtained by cultured explant on MS medium supplemented with 2 mg/l Kin, 2 mg/l Kin + 2 mg/l IBA or 3 mg/l Kin + 3 mg/l IBA. MS medium supplemented with 2 mg/l IBA giving the highest number of leaves per explant. While, in multiplication stage, MS medium supplemented with 0.3 mg/l NAA + 0.5 mg/l BA gave the highest result of survival percentage. MS medium free hormones gave the tallest shoots, the highest amount of leaf number and root percentage. The highest number of shoots was obtained when cultured explant on MS medium supplemented with 0.4 mg/l IBA + 4.0 mg/l BA. Full MS salt strength medium supplemented with 0.4 mg/l NAA +4.0 mg/l Kin gave the highest survival percentage and leaf number. Full MS salt strength medium supplemented with 0.4 mg/l IBA +4.0 mg/l BA gave the longest shoots and the highest number of shoots. 3/4 MS salt strength medium supplemented with 0.4 mg/l IBA +4.0 mg/l Kin or 0.4 mg/l IBA +4.0 mg/l BA resulted in the highest root percentage. In callus induction stage, MS medium supplemented with 2 and 3 mg/l 2,4 D. with or without MnSO4 gave 100% survival percentage. The highest callus dry weight was obtained when cultured explant on MS medium supplemented with 4 mg/l 2,4 D. without MnSO4. In rooting stage, full MS salt strength medium supplemented with 0.5 mg/l IBA led to the highest number of roots, Full MS salt strength medium supplemented with 2 mg/l IBA gave the longest roots. Using peat moss as growing media produced the highest values of survival percentage, shoot length and number of leaves in acclimatization stage.

The effects of heat, UV-irradiation and salinity on growth and metabolism of broad bean plants were investigated. Exposure of bean plants to these stressful factors induced variable significant decreases in the levels of growth parameters throughout the experimental period, as compared with control plants. In relation to controls, direct exposure of broad bean plants to heat, UV-irradiation and salinity stresses, induced significant variable changes in the soluble carbohydrate components. Concurrently with carbohydrate changes, significant variable increases in the activities of both invertase and α-amylase of broad bean plants were maintained throughout the entire period of the experiment.

Two field experiments were carried out at the farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Field Crops Research Institute (FCRI), Agricultural Research Center (ARC), Egypt, during 2008 and 2009 seasons, to evaluate some promising aromatic rice varieties (Egyptian Yasmin, IR77510-88-1-3-3, IR78530-45-3-1-3, IR 74052-177-3-3, IR 71137-51-2 and IR65610-38-2-4-2-6-3) under different sowing dates (April 24<sup>th</sup>, May 10<sup>th</sup>, May 24<sup>th </sup>and June 10<sup>th</sup>). The obtained results showed that rice plants sown on the second date (May 10<sup>th</sup>) surpassed those which sown on the late date of sowing (June 10<sup>th</sup>) in plant height, leaf area index, dry matter accumulation (g m<sup>-2</sup>), tillers number m<sup>-2</sup>, panicle number m<sup>-2</sup>, number of filled grains panicle<sup>-1</sup>, 1000–grain weight, straw yield and grain yield as well as aromatic level in both seasons. There was no significant difference between rice sown on the April 24<sup>th</sup> or May 10<sup>th</sup> in the most studied traits. Delay in sowing date significantly increased unfilled grains %, protein % and amylose content % in the two seasons. Aromatic rice varieties varied significantly in most measurements of growth, grain yield and yield attributes, in both seasons. Plants of the Egyptian Yasmin variety having the highest values in the most mentioned traits among the other tested varieties in the two seasons. Plants of Egyptian Yasmin in the two seasons and IR 77510 in the first season produced the greatest grain yield with high aroma level. Plants of IR 65610 variety produced the lowest grain yield in the two seasons. Concerning correlation coefficient among studied characters, grain yield had highly significant positive effect with 1000 grain weight and number of grains per panicle and significant positive with number of panicles m<sup>-2</sup>. It can be concluded that the optimum sowing date of Egyptian Yasmin variety is April 24<sup>th</sup> and May 10<sup>th </sup>while, sowing date of May 10<sup>th</sup> is the one optimum for IR 77510, IR 78530 and IR 71137. Generally aromatic varieties i.e. Egyptian Yasmin, IR77510-88-1-3-3, IR78530-45-3-1-3, IR 74052-177-3-3, IR 71137-51-2 and IR65610-38-2-4-2-6-3 could be recommended to be sown in April 24<sup>th</sup> and May 10<sup>th</sup>.

Soil microbial biomass is considered to be an important N pool in soil–plant N dynamics in terrestrial ecosystems. This study was carried out at the Rice Research and TrainingCenter during 2007 and 2008 rice growing seasons to evaluate the potential use of these microorganisms as a natural bionitrogen source under two paddy soils. Three nitrogen sources i.e. rice straw compost, sludge and Urea were used under fresh and autoclaved soils with the rice variety Giza 177 in a pot experiment. Results obtained showed that the pot treated with organic mater recorded the maximum value of total N uptake and microbial biomass nitrogen( MBN) uptake, followed by Urea treated pots. While, pots amended with straw exhibited a lower microbial N forming ability than those amended with sludge under both soils. Nitrogen mineralization (NH<sub>4</sub>) rate was significantly affected by nitrogen and microbial N sources. The ammonium concentration increased with straw compost application, which was delaying the utilization of microbial N sources in the rice culture. The results showed that MBN uptake and proportion of plant nitrogen derived from microbial nitrogen sources (P<sub>fix</sub>) were under fresh soil treatment found to be higher than autoclaved soil treatment in both soils. A positive correlation was found between the P<sub>fix </sub>and the total N in the shoot under both soils for the rice variety under study. The results also showed that microbial biomass N was governed not only by the soil type but also by the type of the nitrogen source. The addition of sludge to fresh soil increased total MBN uptake and consequently could be indirectly beneficial to rice production especially in poor soils. Thus, it can be concluded that soil microbes contribute to plant growth by serving as a N source during the rice growing season.

Growth and root distribution of 10 years old Flame Seedless grapevines grown in a sandy soil under different supporting systems were studied during 2007 and 2008 seasons. At four vineyards, five feddan/each the objective was studying the effect of the geometrical shape of four supporting systems: Telephone (Double T), Y-shape, Gable and Baron shape on vines growth and roots distribution. Planting distance was 1.75 X 3.0 m between the vines and the rows for all types of supporting systems. Telephone and Y – shape vines were quadrilateral cordon trained, spure pruned and vines load was 56 buds/vine.
While Gable and Baron shape vines load was 64 and 96 buds/vine and trained according to quadrilateral cordon and mixed pruning respectively. Study of the grapevines root system.
The results revealed that Telephone (Double T) and Y shape enhanced budburst date in comparison with Baron and Gable shape, while the later two types of supporting systems improved budburst number and percentage per vine, fruit full shoots number/vine and fertility coefficient. Also these two types had the maximum total leaf area per vine, leaf area index, shoot length, pruning wood (kg/vine) and wood ripening coefficient significantly as compare with Telephone (Double T) and Y shape during seasons of study. Concerning physical and chemical properties of the yield: Data showed that Baron and Gable shape increased these parameters and Gable shape have the highest values in TSS% and the lowest values in total acidity percentage compared with other types of supporting systems. As for total carbohydrates canes content%, leaf area (cm<sup>2</sup>)/cluster and anthocyanin (mg) in berries skin/100 gm fresh weight, data showed that Baron shape had the highest significant values in this respect followed by Gable shape.
Regarding leaf petiole N, P and K content (%) high significant values were found in the vines supported with Baron shape and the lowest values resulted from the vines trellised with Telephone (Double T) and Y-shape in the two seasons of the study.
Grape vines roots systems: Data revealed that Baron and Gable shape increased total roots densities in horizontal and vertical direction and its diameters, also distance of 50 cm from vines trunk and depth of 60 cm from soil surface had the maximum values in total roots densities and its percentage, followed by upper soil layer (30 cm depth) and 25 cm distance. While minimized values resulted from deeper layer (90 cm depth) and third distance from the trunk (75 cm). Therefore Baron and Gable supporting systems seems to be better than Telephone (Double T) and Y-shape and preferable to maintain reasonable yield with good quality from Flame Seedless grapevines.

Two field experiments were conducted during 2008/2009 and 2009/2010 seasons under new irrigation system (Sprinkler irrigation) at the Experimental Farm of Ismailia Agric Res. Station, ARC, to investigate the impact of fertilization treatments (in terms of mineral N levels either alone or combined with Nitrobein (bio- N fertilizer) on yield quantity and its quality as well as analysis of some flax genotypes i.e. Sakha 3, Viking, Sakha 2 and the flax strain 2419/1. The main finds could be summarized as follows:
The results showed that flax Sakha 3 variety ranked first and surpassed the other three genotypes in straw yield characters. While, flax 2419/1 strain achieved highest estimates regarding seed yield characters.
There was gradual increments as increasing nitrogen levels either in alone case or combined with Nitrobein (bio-fertilizer) concerning all straw and seed yield characters except for fiber fineness which was decreased. The difference between nitrogen treatment at 60 kg mineral nitrogen /fad + Nitrobein and added 75 kg N/fad did not reach the level of significant in most characters especially fiber, seed and oil yields/fad.
The interaction between genotypes and nitrogenous fertilization treatments had significance effect on straw and fiber yield/fed, fiber fineness, 1000 seed weight as well as seed and oil yield/fad.
Results revealed positive and significant correlation values between straw yield/fad and each of technical length/ plant, straw yield/plant, fiber yield/fad as well as per plant, fiber length and long fiber%, also between seed yield/fad and each of seed yield/plant, No. of capsules/plant, No. of seeds/capsule, 1000 seed weight and seed oil%.
Path coefficient analysis indicated that the long fiber percentage, fiber yield/plant and their interaction considered as the most important characters to increase fiber yield/fad. In the same time, seed yield/plant, No. of seeds/capsule and their interaction had similar effect for increasing seed yield/fad within the studied four flax genotypes.
It could be summarized that for maximizing the productivity with best quality, minimizing the production cost of mineral fertilizer and environmental pollution for the tested flax genotypes, it could be recommended to inoculating Sakha 3 variety seed with 1.5kg/fad Nitrobein and fertilized their plants with 60kg/fad mineral nitrogen.

The present investigation was carried out at El-Gemmeiza Agricultural Research station, Agricultural Research Center (ARC), Egypt during four successive seasons from 2007/2008 through 2010/2011. Three crosses were used among five parental varieties, namely P<sub>1</sub>xP<sub>2</sub> (1), P<sub>3</sub>xP<sub>4</sub> (2) and P<sub>4</sub>xP<sub>5 </sub>(3) five populations (P<sub>1</sub>, P<sub>2</sub>, F<sub>1</sub>, F<sub>2</sub> and F<sub>3) </sub> for each cross were used in this investigation. Highly significant heterotic values in positive direction were found for all charcters except for plant height and 1000-grain yield in the first cross, spike length in the second cross, and plant height, No. of grains/spike and No. of spikes/plant in the third cross. Over domenance for all characters except plant height and 1000-grain weight in the first cross, spike length in the second cross and No.of grains /spike in the third cross was detected. Inbreeding depression was obtained in two out of three crosses for spike length, No.of grains/spike, No.of spikes/plant, 1000-grain weight and grain yield/plant and in one out of the three crosses for plant height. The important roles of both additive and non-additive gene actionwere found in certain studied traits. Significant positive F<sub>2</sub> deviation (E<sub>1</sub>) were indicated for plant height in the third cross, No.of spikes/pant and grain yield/plant in the second and third crosses and 1000-grain weight in the first and third crosses. High to medium values of heritability estimates were found to be associated with high and moderate expected and actual gain in most traits. These obtained results indicated that, these traits could be used in the early generations, but would be more effective if postponed to late generations.
