To improve agronomic and quality in bread wheat, this experiment was performed in 2015/16 and 2016/17 seasons at Sakha Agricultural Research Station, Egypt to study performance of ten bread wheat (<em>Triticum aestivum</em> L.) genotypes (Giza 171, Sakha 95, Gemmeiza 12, Shandweel 1, Sids 12, Sids 14, Misr 3, Line 1, Line 2 and Line 3) and their forty-five F<sub>1</sub> crosses were evaluated for sixteen agronomic and grain quality characters. The mean squares for genotypes, parents, crosses, parents vs. crosses, general and specific combining ability were significant for most studied characters. The ratio of general and specific combining ability was more than unity for all characters and both additive and non-additive gene effects were important in controlling the studied characters with more importance for additive effects. The best performance was detected in Sakha 95, Sids 14 and Shandweel 1 for grain yield plant<sup>-1</sup>, all parents except for Sids 12 and Giza 171 and Shandweel 1 for yellow rust, Line 1 for stem rust and Gemmeiza 12 and Sids 12 for dry gluten. The best combiners were Sakha 95, Sids 14, Giza 171 and Misr 3 for grain yield plant<sup>-1</sup> and Giza 171, Sakha 95, Gemmeiza 12 and Shandweel 1 for wet and dry gluten. Grain yield plant<sup>-1</sup> had positive significant correlation with grain filling rate, plant height, number of spikes plant<sup>-1</sup> and kernel weight. The correlation of dry gluten was significant and positive with wet gluten and negative with hydration capacity percentage. Path coefficient analysis showed that the highest positive direct effect on grain yield plant<sup>-1</sup> was obtained by grain filling period, wet gluten, days to maturity and days to heading. On the other hand, the highest negative direct effect was detected by dry gluten, hydration capacity percentage and days to anthesis. The highest positive direct effect on dry gluten was obtained by wet gluten, grain filling rate and days to maturity. Meanwhile, the highest negative direct effect on dry gluten was obtained by grain yield plant<sup>-1</sup>, hydration capacity percentage and days to anthesis. Using stepwise regression, days to heading, grain filling period and rate, kernel weight, yellow rust resistance and electrical conductivity had justified the maximum of grain yield plant<sup>-1</sup> changes. Number of kernels spike<sup>-1</sup>, wet gluten and hydration capacity percentage had justified the maximum of dry gluten changes. Giza 171 × Misr 3, Line 1 × Line 3, Sids 12 × Misr 3, Giza 171 × Line 2, Sakha 95 × Shandweel 1, Sakha 95 × Gemmeiza 12 and Shandweel 1 × Misr 3 crosses had high yield potentiality and resistance to yellow rust and moderately susceptible to stem rust, consequently these crosses will be favorable in wheat breeding programs. Sakha 95 × Gemmeiza 12 and Sids 12 × Misr 3 were the best crosses for dry gluten and will be promising in breeding for wheat grain quality.

A field Experiments were carried out during two winter successive seasons 2011/2012 and 2012/2013 at Sakha Agricultural Research Station. AgriculturalResearchCenter at the north region of Delta Egypt, to illustrate the importance of studying sowing dates of some wheat cultivars. Ten cultivars of bread wheat (Sakha 93, Sakha 94, Giza 168, Misr 1, Misr 2, Gemmeiza 9, Gemmeiza 11, Sids12, Shandawel 1 and Giza 171) were sown at 20<sup>th</sup> October, 20<sup>th</sup> November and 20<sup>th</sup> December. Sowing date were separated and wheat cultivars were distributed randomly in the every experiment. The results indicated that there were significant differences among the three sowing dates for all studied traits in both seasons. Sowing on 20<sup>th</sup> October recorded the lowest days to heading and straw yield, longest time to maturity. Meanwhile, sowing on 20<sup>st</sup> November recorded the tallest plants, highest number of spikes/m<sup>2</sup>, number of grains/spike and grain yield. On the other hand, sowing on 20<sup>th</sup> December recorded the decreases in yield and increases in protein percentage. The differences among bread wheat cultivars were significant in both seasons. Misr 2 recorded the highest number of days to heading and maturity. Sakha 94 recorded the highest number of tillers/m<sup>2</sup>. Giza 171 produced the highest values for 1000- grain weight. Misr 2 and Sakha 94 recorded the highest number of grains/spike and straw yield. Meanwhile, Misr 1 and Gemmeiza 9 recorded the highest grain and straw yields/Fed. Giza 168 recorded the highest values for both of harvest index and protein percentage. Sakha 94 recorded the highest number of days to heading and maturity and plant height when sowing on 20 November. Gemmeiza 11and Giza 171 recorded the highest values for 1000- grain weight in two seasons when sowing on 20 November. It can be concluded that sowing Giza 168 and Misr 1 on different sowing dates, sowing Gimaza 9, Gemmeiza 11, Shandaweel 1 and Giza 171 on optimum date and sowing Misr 2 on the late date are recommended for optimum grain at Kafr elsheikh area.

This research was conducted in the Laboratory of Plant Tissue Culture, Vegetable and Floriculture Department, Mansoura University, Egypt during 2016/2017. The aim was to use tissue culture technique for callus production and enhancing total phenolics (TPC) and flavonoids (TFC) content in suspension culture of garden balsam(<em>Impatiens balsamina </em>L.) which belongs to Family Balsaminaceae, which has many important secondary metabolites in its different organs. Callus was initiated on leaf discs cultured on MS medium supplemented with either 2,4-D or NAA at different concentrations (0.5, 1.0 and 1.5 mg/l), besides the control (MS-free hormone medium) with a fixed BAP concentration (0.5 mg/l). Also, suspensions were supplemented with either yeast extract or chitosan (0, 50, 100 and 200 mg/l) for enhancing accumulation of phenolics and flavonoids content for two separated elicitation periods (24 and 48hrs.). Data showed that the highest callus formation percentage (100%) was obtained from leaf explants cultured on MS medium supplemented with either 1.0 mg/l 2,4-D+0.5 mg/l BAP or 1.5 mg/l NAA+0.5 mg/l BAP. Also, these superior treatments produced the biggest callus volume (9.38 and 9.19 mm<sup>3</sup>, respectively). The heaviest callus fresh and dry weights (8.25 and 1.15 g/jar) were recorded for MS medium fortified with 1.0 mg/l 2,4-D+0.5 mg/l BAP. In addition, after 24hrs from the suspensions elicitation, the highest TPC value of 8.298 mg/gdw with 4.18 fold higher than the control was recorded for suspensions which received 50 mg/l yeast extract. In the same time, 50 mg/l chitosan increased TFC (3.929 mg/gdw). The matter was partially similar after 48hrs, with a slight increase in all the elicitation treatments, since the superior treatments after 24hrs still giving a higher TPC and TFC.

The present study was carried out to study the effect of treatment with three doses (5,10 and 15 min) of laser irradiation and evaluate the induced variability on some quantitative characters of the two Egyptian cotton cultivars Giza 92 and Giza 94. The trial was conducted at Sakha Experimental Station, Agricultural Research Center, Kafr El-Sheikh, Egypt during three growing seasons from 2014 to 2016. The results indicated that the laser irradiation decreased the mean performance of yield and yield components for Giza 92, while the Giza 94 variety exhibited increase for yield and yield components. no effect was found for the fiber quality of Giza 92, while better fiber quality was obtained for Giza 94 except for fiber strength which was reduced with the mutagen treatments in M<sub>1</sub> generation. The treatment with laser irradiation increased the variability for most studied traits. The results of kurtosis indicated that most of cases were less than 3 indicated that the variability of plants were distributed as platykurtic so, the individual plants are unconcentrated around the means. Heritability estimated showed high values for boll weight (more than 50%) in M<sub>1</sub> 5 and 10 min and M<sub>2</sub> 15 min , as well as for number of bolls per plant , seed and lint cotton yield per plant, lint percentage and fiber fineness in M<sub>1</sub> of Giza 92, fiber length in all generations of Giza 94. Low values of broad senses heritability (less than 30%) were found for boll weight of Giza 94 in treatment 15 min of M<sub>1</sub> and M<sub>2</sub>, as well as in treatment of 10 min in M<sub>2 </sub>for Giza 92. The fiber fineness exhibited low heritability value for Giza 94, while Giza 92 exhibited high values of heritability. The relationship between the yield and boll weight was significantly positive for control treatment, and between the yield and lint percentage in M<sub>2</sub> and M<sub>3</sub> of treatment 10 min for Giza 92, while Giza 94 exhibited insignificant correlation between yield and lint percentage and fiber fineness. Giza 92 exhibited insignificant correlation between yield and both fiber strength and fiber length, while the cultivar Giza 94 revealed negative and significant correlation in M<sub>1</sub> for the treatment 5 and 10 min, as well as 15 min in M<sub>1</sub> and M<sub>2</sub> between the same traits.

Two pot experiments were carried out during growth seasons of 2016 and 2017 at the experimental station of faculty of agriculture, Benha University. The investigation target was to find out the effect of using plant growth promoting rhizobacteria either PGPR-group (A) containing 7×109 cell suspension of each (Azo. lipoferium D178, B. megaterium ATCC14581 and B. circulans ATCC4513) or PGPR-group (B) containing 7×109 cell suspension of each (A. chroococcum EMCCN1458, B. megaterium ATCC14581 and B. circulans ATCC4513) individually or in combination with mineral fertilization rates (25, 50, 75 and100%) NPK on the vegetative growth characteristics and chemical constituents of Moringa oleifera plant at 75 and 150 DAS. The combination of plant growth promoting rhizobacteria PGPR group (A) and inorganic fertilizers treatments gave the highest values of dehydrogenase (DHA), alkaline phosphatase (ALP) and nitrogenase (N2-ase) activities as compared with each one individually. In all treatments, enzymes activities were increased to reach the maximum values after 90 DAS. The highest values of enzymes activity recorded for treatment which inoculated with PGPR group (A) and amended with ¾ of mineral fertilizers followed by treatment which inoculated with PGPR group (B) amended with ¾ mineral fertilizers. Vegetative growth measurements, photosynthetic pigments, promoting endogenous phytohormones, total phenolics, flavonoids and ascorbic acid contents as well as the highest values of antioxidants activity were recorded for treatment that inoculated with PGPR group (A) amended with ¾ of mineral fertilizers followed by treatment that inoculated with PGPR group (B) amended with ¾ mineral fertilizers, respectively compared to mineral fertilization. Abscisic acid was reduced with different applied treatments as compared to the control, but the reduction was more obviously clear for treatment of PGPR group (B) amended with 1/2 mineral fertilizers. While, salicylic acid was increased with the different tested treatments compared with the control and reached its maximum values with PGPR group (B) amended with ¾ mineral fertilizers and PGPR group (A) with ¾ mineral fertilizers treatments, respectively.

Nodule-forming rhizobia and specific legume host are forming the mutualistic interactions between them which involve a series of signaling molecules leading to the establishment of a strong and functional symbiosis between the two partners. The success of symbiotic relationships and form nodule are depend on competitive ability and legume host specificity of rhizobia together with the ability of both rhizobia and legumes to release functionally divergent active molecules. The parameters showing the growth and metabolism of <em>Vicia faba</em> in response to cultivation with different Rhizobia and endophytic bacteria were determine. Combination of <em>Rhizobium</em> with different endophytic bacteria had a positive effect on growth parameters, photosynthetic pigments and carbohydrate content in shoot of <em>Vicia faba</em>, at flowering stage.

An experiment was conducted at the Experimental Farm of Sakha Agricultural Research Station 31° 07\\ N and 30° 57\\, Kafr El-Sheikh, Egypt, during 2015 and 2016 seasons to study the effect of skipping one irrigation at different growth stages and foliar application of zinc on quantitative and qualitative characteristics of sunflower cultivar Sakha 53.A split plot design with four replications was used. The main plots were devoted to water treatments <em>i.e.</em> I<sub>1</sub>= without skipping (control four irrigation during season), I<sub>2</sub>= skipping one irrigation during vegetative stage, I<sub>3</sub>=skipping one irrigation during flowering stage, I<sub>4</sub>= skipping one irrigation during grain filling stage. Sub plot treatments were devoted to foliar application with zinc sulfate , <em>i.e.</em> Zn<sub>o</sub>= water application, Zn<sub>1</sub>= 0.5% and Zn<sub>2</sub>= 1% concentration. The results showed that flowering stage was the most sensitive to water deficit stress and skipping irrigation at this stage caused marked decrease in chlorophyll content in leaves, relative water content (RWC %), seed oil %, seed yield and its components, while increased proline content and seed protein % in the two growing seasons. Zinc spraying had significant effect on all attributes in this research. In general, application of Zn could be used as a good tool to increase yield of sunflower under drought stress.Also, the highest mean values for seasonal amount of water applied and water productivity were recorded under traditional irrigation. From this study we can be concluded that it is possible to gain high seed yield with less quantities of applied water when the irrigation skipping happens at vegetative stage with application of 1% zinc sulfate .

An efficient <em>in vitro</em> callus induction and plant regeneration Protocol has been established for a value aromatic and medicinal plant, <em>Aloysia triphylla</em> by using shoots tips and leaf disc as explants. The nutrient MS medium with different concentrations of auxins NAA, IBA and 2,4-D alone or in combination with different cytokinins BA, TDZ and Kin were used to induce callus formation. Shoots tips and leaf disc cultured on MS medium supplemented with 2,4-D at 1.5 mg/L in combination with BA at 1 mg/L induced Maximum callus formation percentage of 91.7 and 100 %, respectively coupled with the highest callus fresh weight of 9.71 and 10.66 g, respectively. For Callus differentiation, callus derived from shoot tip and culture on half strength MS media fortified with TDZ at 2 mg/L and GA<sub>3</sub> at 0.5 mg/L recorded 100 % callus differentiation percentage and significantly the highest value of shoots number (12.92 shoots). Healthy regenerated shoots were rooted <em>in vitro</em> on MS containing 0.5 mg/L IBA. Plantlets with well-developed root and shoot systems were successfully acclimated (97%) and established in pots containing mixture of soil, sand and peatmoss (1: 1: 1).

Dahlia is one of the popular cut flowers in the world which characterized by the rich variety and attractive flower colors. Hence, in a field study 100, 200, 300mgL<sup>−</sup><sup>1 </sup>gibberellic acid (GA<sub>3</sub>) and salicylic acid (SA) were used during two successive seasons 2015 and 2016 to determine the possible role of each growth regulator in improving marketable quality, increasing yield and vase life of dahlia. Results indicated that the tallest plants (118.43cm) were those sprayed with GA<sub>3</sub> at 200mgL<sup>-1</sup>. Additionally, it showed that foliar application of GA<sub>3</sub> or SA at 200mgL<sup>−</sup><sup>1</sup> significantly increased the number of branches plant<sup>-1</sup>, fresh and dry weight plant<sup>-1</sup>, leaf numbers, leaf area plant<sup>-1</sup>, flower numbers, flower quality and vase life as well as tuber length, and numbers plant<sup>-1</sup>. The most rapid flowering (39.57 days after planting) occurred when plants were sprayed with GA<sub>3</sub> at 200mgL<sup>1</sup>. Concomitant to the enhancement in the vegetable and flowering attributes, an increscent in the anthocyanin content and total soluble solids was observed in the petals by increasing GA<sub>3</sub> and SA concentrations up to 200mgL<sup>−</sup><sup>1</sup>. Additionally, a significant increment in the total chlorophyll content was recorded with GA<sub>3</sub> and SA treatments. In conclusion, the vegetative and flowering characters of dahlia could be improved by application of either GA<sub>3</sub> or SA.

Two greenhouse experiments were conducted during 2014/ 2015 and 2015/2016 seasons in the Experimental Station Farm, Faculty of Agriculture and Natural Resources, Aswan University, Egypt on a sandy textured soil under unheated plastic houses. The target fertilization program seeks to achieve the best combination of various organic and NPK mineral fertilization that lead to the highest yield and quality of produced sweet pepper plant ''Lama Star F<sub>1</sub> hybrid'' especially during the winter season. Therefore, 12 treatments were arranged in a Split plot layout in complete randomize block design with three replicates. Chicken manure at the rates of (10, 15 and 20m<sup>3</sup>/fed.) were randomly arranged in the main plots, while NPK mineral fertilization at rates of (0:0:0, 50:30:50, 100:40:80, and 150:50:110 Kg N:P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O/fed., respectively, were randomly distributed in the sub-plots. The obtained results demonstrated that the treatment combination of chicken manure at 20 m<sup>3</sup>/ fed. Plus either 150:50:110 or 100:40:80 Kg. NPK/fed. brought about the highest significant mean values of most studied characters as vegetative growth characters (i.e. plant height, number of leaves/plant, the number of branches /plant and plant fresh weight); yield characters {i.e. No. fruits /plant, average fruit weight (g), early yield/m<sup>2</sup> (kg) and total yield/m<sup>2 </sup>(kg)}; fruit quality (i.e. TSS %,vitamin C, and non-reducing fruit sugars); chemical analysis characters (<em>viz</em>,a, b and total chlorophyll and N, P, K contents in leaves and fruits ) during both seasons of the study as compared to the other treatments. Based upon, the reported results, it is possible to conclude that, the combination among 20 m<sup>3</sup>/fed. of chicken manure plus either 150:50:110 or 100:40:80 Kg. NPK/fed. considered as the optimal combination treatment whereas it gave the highest mean values of vegetative growth characters, yield and its components and fruit quality of pepper plants grown under plastic houses conditions at Aswan governorate.
