The present investigation was carried out at the experimental farm of Malawi Agricultural Research Station, El-Minia Governorate, Egypt during 2009/2010 and 2010/2011 seasons to investigate the effect of sowing dates (15th October, 30th October and 15th November) and phosphorus fertilizer (0, 15 and 30) kg P2O5 /fed on root rot disease incidence, yield and its quality of three sugar beet varieties i.e. Farida, Kawemira and Montibianco. A split-split plot design with three replications was used, sowing dates were allocated in the main plots, phosphorus fertilizer was assigned in the sub plots while, sugar beet varieties were distributed in the sub- sub plots.
The results revealed that sowing date15th October significantly reduced root rot disease incidence and increased all quality parameters, i.e. sucrose ,sex, Na, K, alpha amino N,SLM and extractability percentages except purity % as well as productivity traits (top and root yields ) in the two growing seasons. The above varieties of sugar beet significantly differed in all studies traits in the two growing seasons. Phosphorus fertilizer significantly effected on all studies traits in both seasons, except sugar yield and (root yield and root fresh weight ) in the first season only. Planting Kawemira sugar beet variety when received 30 kg P2O5 / fed in 15th October significantly increased yields of root and top (ton/fed) in the second season.

A.
Shams
Two field experiments were carried out at the experimental Farm of the Faculty of Agriculture, Moshtohor, Benha university, Qalubiya Governorate, Egypt during the two successive seasons of 2010/2011 and 2011/2012, to study the effect of foliar application with bulk or nano-titanium dioxide (TiO2 <10 nm) with three levels (0.01, 0.02 and 0.03 %) on the growth and nitrate content of lettuce (Lactuca sativa var. capitata cv. Great lakes)
As a photocatalyst, nano-TiO2 under light could cause an oxidation–reduction reaction. The nano-TiO2 treatments have obvious effects on the improvement of growth and development in lettuce; however, bulk TiO2 treatments have only little effects.
It was demonstrated that nanoanatase TiO2 (0.03%) could greatly improve growth (fresh and dry weight) and pigments of photosynthesis (β-carotene, chlorophyll a and b) of lettuce. The results also, showed that TiO2 nano particles (0.03%) recorded the highest total yield (16.434 ton fed-1) and the lowest content of nitrate in lettuce leaves (182.5 µg g-1 DW) as an average in both seasons.
Nano-anatase TiO2 treatment could enhance growth, photosynthesis efficiency, activities of nitrate reductase and consequently decrease nitrate content in lettuce plants.

This research was carried out at El-Baramoon Horticulture Research Farm, Dakahlia Governorate, Egypt, during the summer seasons for five years. Seven cowpea genotypes, including 6 selected lines and Cream 7 cultivar were grown in randomized complete blocks design with three replications. These inbred lines obtained from Cream 7 cultivar after five generations of inbreeding and selection and were evaluated. The differences among means of most tested lines appeared significance and all the selection lines were superiors than check cultivar for the total yield trait of cowpea. The results indicated that the strains S3, S2 and S6, respectively were superiors than check cultivar (Cream 7) for the qualitative and quantitative traits of cowpea crop. The results revealed that the pure line selection method within Cream 7 cultivar proved to be effective in separating new promising white lines superior of yield and quality. A correlation study indicated that the existence of high positive correlations between total yield and each of number of pods per plant, pod filling, dry weight per plant and 100 seed weight. On the other hand, all the studied traits except pod length and pod width were positively correlated with total yield at the two seasons of study.
Finally, it must be concluded that such new selected superior lines S3, S2 and S6 respectively had superior for the qualitative and quantitative characters, in addition, their adaptability for Egyptian conditions. So, it could be utilized commercially as new promising cultivars or in breeding programs to be utilized from some promising traits.

This study was carried out during the two successive seasons of 2012 and 2013 on Manfaloty and Wonderful pomegranate trees at5 and 3-years old respectively, the trees were spaced at 4x4 m. grown in a sandy soil. The highest values of yield and its components i.e., fruit weight, fruit number /tree and yield /tree were recorded when Manfaloty and Wonderful pomegranate trees treated with GA3 at 50 or 100ppm, CaCl2 4 %, kaolin 2.5 or 5 % and bagging treatment. The lowest percentage of fruit creaking and sunburn were obtained with bagging treatment followed by kaolin 5% and spraying by CaCl2 and GA3 treatments compared with the control treatment .All treatments caused a highly significant increase in Marketable fruits %. Bagging treatment gave the highest Marketable fruits percentage compared with the control and other treatments. The highest fruit length and diameter obtained by GA3 50 or 100ppm and CaCl2 2 or 4% treatment. Furthermore,GA3, kaolin and bagging treatments improvedSSC, total acidity and SSC/acid ratio ,meanwhile the highest anthocyanin content in juice and peel was obtained by bagging and spraying kaolin 5% treatments in both cultivars. Therefore, these treatments could be recommended for improving Manfaloty and Wonderfull pomegranate cvs performance under similar conditions of this study.

In order to grow kenaf crop in a large scale for manufacturing paper pulp for paper industry, many agronomics factors need to be known, among them nitrogen fertilizer levels and plant population density for maximum yield. Thus, experiments were conducted to determine the effect of four nitrogen levels (0,75,150, and 225kg N/ha) and two plant population (15 and 25 plants/m2) on seasons kenaf crop (Var. India) during the two growing of 2009 and 2010 at the field of General company for Paper Industry located 25 km North Basrah town. Increasing nitrogen fertilizer resulted levels in increases in plant height and stem diameter. Application of 255 kg N/ha gave highest bark percentage (38.9 %) and consequently increased bark yield (6.36 ton/ ha). Planting 25 plants/m2 gave highest plant height (307.9 cm.), bark percentage (34.33 %) and bark yield (5.54 ton/ha) but reduced stalk diameter . The interaction between highest nitrogen fertilizer (255 kg N/ha) and highest plant population density (25 plants/m2) gave highest stalk yield (18.03 ton/ha) and bark percentage (41.94%). It was concluded that kenaf crop has good potential to be planting on large scale by increasing nitrogen fertilizer to 255 kg N/ha and highest plant population (25 plants/m2) under Basra environmental conditions.

This study was carried out in two successive summer seasons (2012 and 2013), at the Experimental Farm of Research Station, Qanater El-Khairya, El- Kalupia Governorate, Agriculture Research Center. The main objectives of this investigation were to estimate of magnitude of additive and non-additive gene effects for some traits in an attempt to stablish some inbred lines. The study also aimed to estimate heterosis degree, relative to mid, better parents and the standard cultivar to determine the hybrid vigour for some important characters. Phenotypic correlation coefficients between all possible pairs of the different studied traits were estimated. The following traits were assessed: early and total yield as fruit number and weight, average fruit weight, shape index, skin and flesh colour, flesh thickness, β carotene, vitamin C and sugars contents. The obtained results showed that both additive and non-additive gene effects were involved, the additive gene effects appeared to be playing the main role in the inheritance of all studied traits, since the estimated GCA: SCA ratio values ranged from 4.4 to 57.8. None of the parents found to be good combiner for all characters. Generally the two parents Magyar Kincs and Muszkotàly were the best combiner for breeding to most characters. It is noticed that the bestcombinations were resulted from crossing between these two parents or between one of them and other parent.
Hybrid vigour was detected for early and total yield, as well as, most fruit characters. In some crosses, high better parent heterosis and potence ratio values were given for these traits supporting the over dominance hypothesis. Other degrees of dominance were observed by many crosses concerning some traits. High estimated standard heterosis were reflected by three crosses i.e., Shahd El-Dokki X Muszkotàly, Shahd El-Dokki X Magyar Kincs and Magyar Kincs X Muszkotàly for yield and most important traits. Hence, it could be suggested that these crosses may be recommended as new promising hybrids for commercial production of melon after further evaluation. Desirable correlations were detected between many pairs of character. In many cases phenotypic correlations used to help breeders in selecting and improving quantitative of difficulty measured characters through the selection for simply and correlated ones.

A two-year study was carried out at Sids Agricultural Experiments and Research Station, A.R.C., Beni - Sweif Governorate, Egypt during 2009/2010 and 2010/2011 winter seasons to investigate the possibility of increasing fodder beet productivity and net return per unit area by intercropping fodder beet with some field crops for encouraging Egyptian farmers to grow fodder beet in their fields. Fodder beet plants were grown in one row on all ridges (60 cm width) with intercropping barley, wheat or faba bean plants on the other side of the first and third ridges. Also, fodder beet plants were grown in both side of beds (120 cm width) with intercropping barley, wheat or faba bean plants in the middle of second and forth beds in addition to sole plantings of all the tested field crops. A split plot design in randomized complete block design in four replications was used. The results can be summarized as follows:
Intercropping barley, wheat and faba bean with fodder beet led to decrease in yields of all tested field crops in comparison with sole plantings of these crops. As a result of intercropping, root yield of fodder beet was decreased by 18.44, 17.10 and 17.78% in the 1st and 2nd seasons and the combined analysis, respectively, as compared with sole fodder beet. Growing fodder beet on ridges (60 cm width) under intercropping and sole cultures had higher values of all the studied traits of fodder beet than those gown on beds (120 cm width) , whereas, yields of barley, wheat and faba bean were not affected. The interaction between cropping systems and ridge width was not significantly affect all the studied traits of all the tested crops.
For competitive relationships, intercropping fodder beet with barley, wheat and faba bean increased land equivalent ratio (LER) as compared to sole fodder beet. LER ranged from 1.05 to 1.22 with an average of 1.11. All values of relative crowding coefficient (K) exceeded 1.00. K of barley, wheat or faba bean was higher than those of fodder beet. With respect to dominance analysis, barley, wheat or faba bean plants are dominant components and fodder beet plants are dominated components.
Intercropping fodder beet with barley, wheat and faba bean increased total and net returns by about 8.98 and 11.02 per cent, respectively, as compared with sole fodder beet. Net return of intercropping fodder beet with barley, wheat and faba bean was 8903, 9015 and 14075 L.E. per faddan as compared with sole fodder beet (9605 L.E.). Growing fodder beet with faba bean plants on ridges (60 cm width) gave the highest financial return as compared with sole fodder beet. This study concluded that growing fodder beet plants in one row on all ridges (60 cm width) with intercropping faba bean plants on the other side of the first and third ridges gave high yield of fodder beet.

Chrysanthemum (Chrysanthemum morifolium, L.) is one of the most the important cut flower. The aim of this study to investigate the effect of some chemical preservative solutions to improve keeping quality ,enhancing water uptake, delaing leaf wilting and leaf yellowing and extending the shelf life period of cut chrysanthemum flowers .The flowers were held in the vase solution containing silver nitrate at 75ppm + citric acid at 150ppm + sucrose at 3%(T2) or silver nitrate at 75ppm + citric acid at 150ppm + sucrose at 5% (T3) was increased significant vase life (19.5 and 17.2 days, respectively), flower diameter, water uptake ,total soluble sugars % and reducing sugars in leaves , decreased chlorophyll "a" and ''b", pectin in flowers and leaves and reduced the number of bacteria in the vase solution to zero . Super blue green at1cm/L +Sucrose at 3 or 5% (T 6 &T7) increased vase life in 2nd season . On the other hand, benzyl adenine + citric acid + sucrose (T8, T9 , T10 & T11) treatments didnot enhance vase life and recorded the largest number of bacteria (1163×106) in vase solution. All holding vase solution treatments gradually increased flower diameter and decreased water uptake with extended shelf life periods. Concerning water balance in treatments T2 ; T3 ; T6 ; T 11 and Potassium Nitrate +150 ppm citric acid + sucrose ( T12 , T 13, T14 & T 15) had petter vase life with respect to water balance during the shelf life periods as compared with control and other holding solutions under study. All holding vase solutions recorded gradual decreases in total soluble sugars % in flowers with extending shelf life periods.. In most cases, reducing sugars% gradually increased up to 8th day then decreased after wards.

In order to study the effect of genotype × environment interaction and stability of sugar beet genotypes for seven cultivars, viz Lilly, DS 9004, Gazella, Oscar Poly, Pather, Toro and Hercule. A field trail was sown in eight environments as major four locations (Sakha, Giza, El-Fayoum and Malawy) for two years (2011/12 and 2012/13) using a randomized complete block design, with three replications. Analysis of variance for root yield, sugar yield and sugar content showed that the environment and genotype and genotype × environment interaction (GEI) were significant. GEI were evaluated by two methods (phenotypic stability and AMMI model).
According to phenotypic stability analysis results, genotype (Lilly) was the most stable for sugar content and root and sugar yield. This genotype recorded the highest root and sugar yield (30.34 and 5.22 ton/fed, respectively) across environments, and Sakha environment had the highest mean values of environments followed by El-Fayoum environment.
AMMI model explained most of the genotype × environment interaction (85.97%, 83.34 % and 86.47 %) for root yield, sugar content and, sugar yield, respectively. Lilly was the best genotype based on the biplot, and showed specific adaptation to Sakha and El-Fayoum location. The varieties Pather, Hercule and Toro were the lowest variety among the evaluated varieties and it is better not to use it in the studied areas. The genotypes Gazella, Oscar poly and DS9004 had an average genetic potential for the studied traits, but its high general adaptability, then it could be introduced for all areas. Among the locations, Sakha was the best location, and was more similar to El-Fayoum. Meanwhile, Malawy was the poorest location.
Therefore, two stability methods confirmed that Sakha and El-Fayoum are recommended as suitable regions for sowing sugar beet and Lilly variety could be suggested as the best genotype for these locations. Meanwhile, AMMI method showed new information.

The inheritance studies of some quantitative and qualitative characteristics of tomato were carried out using a half diallel crosses mating design to obtain 15 crosses among 6 genotypes.
General (GCA) and Specific (SCA) combining abilities were significant or highly significant for all studied traits. The large magnitude of (GCA) for the vegetative, and total soluble solids (TSS %) traits suggested the importance of additive genetic effects, while the large magnitude of (GCA) and (SCA) for fruit set percentage (FS %), earliness, total yield, average fruit weight (AFW), fruit firmness (FF), number of locules per-fruit (NL/F) and fruit thickness (FT) suggested the importance of additive and non-additive genetic effects.
B5357 cultivar (P5) was a good combiner for plant height (PH), fruit set percentage (FS %), early fruit number (EFN), total fruit number (TFN), total fruit weight (TWF) and total soluble solids (TSS %). Edkawy cultivar (P2) also, was a good combiner for number of branches per plant (NB/P) and number of locules per-fruit (NLF) while Fline cultivar (P6) was a good combiner for average fruit weight (AFW), fruit firmness (FF), and fruit thickness (FT).
