This study was conducted at the Experimental Station and Laboratory of Vegetable and Floriculture Department, Fac. of Agric., Mansoura Univ., Egypt, during 2015/2016 and 2016/2017 seasons to investigate the effect of some natural products and some alternative chemical growth regulators on rooting response‚ growth and chemical composition of cuttings of rosemary (Rosmarinus officinalis L.) plants. The layout of the experiment was completely randomized block design (CRBD) with three replications. The obtained results could be summarized as the following: It is worthy to mention that the highest values of all studied vegetative growth characters and chemical constituents of rosemary were resulted from treating terminal cuttings with coconut milk at the highest rate (75%) in both seasons. With exception, fresh weight of shoots, which, obtained when treating terminal cuttings with seaweed extract at the rate of 50 % and total phenols percentage, which obtained from control treatment (treating cuttings with water only) in both seasons. Using natural products such as coconut milk, seaweed extraction, yeast extract and honey bee were better than using chemical growth regulators like Indole butyric acid (IBA) in both seasons. It can be concluded that treating terminal cuttings of rosemary (Rosmarinus officinalis L.) with coconut milk at the rate of 75 % as natural growth regulator in order to enhance rooting‚ vegetative growth and chemical constituents.

The present investigation was carried out during 2015 and 2016 seasons on three Egyptian mango cultivars (Mangifera indica L.) named Ewais (normal & nubbin), Sedeq and Zebda grown at a private orchard in Idko region under Beheira governorate conditions. The trees were selected to study normal and nubbin fruits of some mango trees productivity and quantification of expressed gene levels as well as trying to make better understanding of embryo abortion phenomenon in mango. Real-time qPCR was used to detect the relative amounts of mRNA of four different genes. Fruit physical characteristics of Ewais (nubbin) cultivar, i e fruit length, width and pulp, stone and peel weights, as well as yield were lower significantly than normal fruits, while its pulp/ stone ratio gave the highest values, in both seasons. The chemical characteristics of Ewais (nubbin), i e TSS, TSS/ acidity, reducing sugars, total sugars and pectin methyl esterase were significantly higher than normal fruits, while acidity, vitamin C and peroxidase were the lowest values. Results showed that the four selected ESTs were differentially expressed in the tissues of normal, aborted embryos and leaves, however, the 4 ESTs (MaAGA, MaAP2, MaERF, and MaMADS) were upregulated in normal embryo tissues compared to aborted embryos of "Ewais". Also the expression levels in the leaves tissues were upregulated in Sedeq and Zebda varieties compared to Ewais leaves. The results of total protein (SDS-PAGE) explained that Zebda and Sedeq cultivars, which had normal fruits gave the highest several bands in both embryos and leaves tissues than Ewais cultivar which had nubbin fruits.

This investigation was carried out during two successive seasons of 2014 and 2015 on mature pomegranate trees cv. Manfalouty grown in calcareous soil at Borg-El-Arab region, Alexandria governorate, Egypt. It was conducted to determine if a combination of fast or slow release (i e phosphorus coated urea PCU 37%) nitrogen fertilizer with different levels of soil moisture can enhance growth of Manfalouty pomegranate trees with high productivity as compared to the current production practices as well as to reduce both rate and number of soil applications during the growing season. The results showed that all vegetative growth, leaf mineral contents and fruit characteristics parameters were significantly affected by interaction between levels of soil moisture of field capacity (FC) and slow-release nitrogen fertilizer. The chemical fruit characteristics, i e TSS, TSS/ acidity, vitamin C and anthocyanin were the maximum values at 50% FC + 400 g actual slow release nitrogen fertilizer, while the acidity value was the highest in the treatment of 100% FC + 200 g/tree as a slow release nitrogen fertilizer in both seasons. The fruit set was the maximum at 75% FC +200 or 300 g actual slow release nitrogen fertilizer in the first and second seasons, respectively. Also, yield showed the highest significant values of 44.1 and 47.1 Kg/tree with the treatment of 100% FC+ 400 g/tree in the first and second seasons, respectively. Moreover, the results showed that the combination between the 100% FC irrigation treatment and the highest amount of slow release fertilizer of 400 g actual slow release nitrogen fertilizer /tree produced the highest values of most vegetative growth traits i.e., tree height, shoot length, dry weight of 30 leaves, and chlorophyll content (SPAD) in both seasons. Also leaf nitrogen, potassium, phosphorus and magnesium content was increased under such conditions.

This study was carried out during three successive seasons, (2013, 2014 and 2015) in a private orchard located in North Sinai governorate, Egypt. The study was conducted on 10 years old Kalamata olive trees planted at 6 X 6 m apart grown in sandy soil, under drip irrigation system and uniform in shape and received the common horticultural practices. The aim of this study was conducted to evaluate Kalamata olive trees irrigation techniques which involve two types (whole root-zone irrigation – alternate partial root-zone irrigation) and three levels of regulated deficit irrigation values based on crop evapotranspiration (irrigated with 100%, 80% and 60% of ETc). The obtained results indicate that alternate partial root-zone irrigation increased vegetative growth, number of inflorescences per shoot, number of perfect flowers, crop yield, fruit oil content and fruit quality characteristics as compared with whole root-zone irrigation technique. On the other hand, the previous parameters recorded strong correlation with the highest level of irrigation treatments (100% ETc control treatment) while, regulated deficit irrigation with 60% of ETc recorded the lowest values in these respect while 80% ETc treatment came in between. In general alternate partial root-zone irrigation technique saved at least 20% of irrigation water as compared with whole root-zone irrigation and improving water use efficiency.

A field study was conducted during 2015 and 2016 seasons in Sakha experimental farm, Kafrelsheikh, Egypt to study the effect of sowing dates and weed control on growth and yield of broadcasted-seeded rice (Giza 179 cv). Three sowing dates viz., May 20th, May 30th and June 10th in individual experiments. Seven weed control treatments i.e., weedy check, Penoxsulam (2.5% OD) at 24 g.ai ha-1, Bispyribac-sodium (2% SL) at 38 g.ai ha-1, Fenoxaprop-p-ethyl (7.5% EW) at 63 g.ai ha-1, Penoxsulam (2.5% OD) plus Azimsulfuron (50% WG) at 14 g.ai ha-1, Bispyribac-sodium plus Azimsulfuron (50% WG) and Fenoxaprop-p-ethyl (7.5% EW) plus Azimsulfuron (50% WG), companied analysis was done for the three sowing dates. The results showed that rice sowing on May 20th reduced the highest number of tillers m-2 and total weeds dry weight while increased dry weight for rice, number of panicles m-2, panicle weight, number of filled grains panicle-1 and rice grain yield as compared to rice sowing on May 30th and June 10th. The application of Penoxsulam (2.5% OD) or Bispyribac-sodium (2% SL) mixed with Azimsulfuron (50 %WG) at recommended doses recorded the lowest number of weed tillers m-2, total weeds dry weight and highest rice yields as compared to weedy check. The interaction between sowing date and weed control treatment was significant for number of tillers m-2, total weeds dry weight, rice yield and its components. Sowing date May 20th with The mixture of Penoxsulam (2.5% OD) or Bispyribac-sodium (2% SL) mixed with Azimsulfuron (50% WG) recorded the lowest total weed characters, highest dry weight, number of panicles m-2 panicle weight, number of filled grain panicle-1 and yield of broadcasted-seededrice under this study conditions. ai= active ingredient ha. = Hectar

Two field experiments were carried out during 2014/2015 and 2015/2016 seasons under two sowing dates, 24th November (optimum date) 25th December (late date) at the Experimental Farm, Faculty of Agriculture, Zagazig University, Sharkia Governorate, Egypt using eight wheat genotypes to estimate genetic variability, phenotypic and genotypic correlations as well as path coefficient for yield and yield component characters. The results indicated significant differences among wheat genotypes for all the studied characters except chlorophyll content at the two seasons and number of spikes/m2 at the 2nd one only. Wheat genotypes Line 3, Sids 12 Misr 1, and Line 4 performed well under the late sowing date in the two seasons for yield and its component. Maximum phenotypic variance (Vp) and genotypic one (Vg) were recorded for number of spikes /m2 under the two sowing dates and plant height under 2nd one only. The (PCV) and (GCV) ranged from 27.69 and 26.08 % to 90.38 and 85.11% and from 20.26 and 12.66 % to 208.31 and 189.59 % for 1000 grain wheat and number of spikes/m2 under 1st sowing date and 2nd one, respectively. The range observed for heritability (bs) was from (58.42) for number of fertile spikelets/spike to (95.3%) for number of grains /spike and from (39.04) for 1000 grain weight to (89.46%) for plant height under 1st sowing date and 2nd one, respectively. Spike length, number of fertile spikelets/spike, number of spikes /m2, number of grains /spike and 1000-grain weight were the most important traits which greatly correlated with grain yield at both genotypic and phenotypic levels. Maximum positive direct effect on grain yield was contributed mostly by 1000-grain weight (1.104), followed by number of grains/spike (0.626) and number of spikes/m2 (0.352).This means that a slight increase in one of these traits may directly contribute to grain yield. Since these characters could be used as selection criteria for improving wheat grain yield.

This study was carried out during the seasons of 2014, 2015 on Washington navel orange (Citrus sinensis L. Osbeck) cultivated in a commercial orchard located in Shiwah Valley near Aga city, Dakahleia Governorate, Egypt. to study the effect of organic fertilization such as humic and Fulvic acid as a soil application on fruit set, dropping and yield of Washington navel orange . The data reveal that adding humic or fulvic acid each alone or together significantly increased the fruit set percentage but reduced pre-harvest drop than the control. The data also, showed that adding humic acid at 30 ml with fulvic acid at 100 ml significantly increased the number of fruit per trees than the other treatments or the control since, this treatment gave a higher yield. Whereas no clear effect had obtained on average fruit weight. Furthermore, both humic or fulvic acid applications gave no clear effect on average fruit juice than the control. So, this treatment gave no clear effect on SSC, total acidity and SSC/acid ratio in fruit juice than the control. but ,thes treatment gave a somewhat increment on average Vit-c in fruit juice.

Rice is considered as one of the most important food crops in the world. Rice plants infected by several plant pathogens. In Egypt, however important diseases of rice namely blast and brown spot are major limitation on rice production and becoming more sever on rice grown in silicon depleted soil. Disease that occurs to plant may reduce the ability of the plant to survive and in more severe cases could eventually lead to plant death. Two field experiments were carried out to study the effect of different sources of biogenic silica nanoparticles on blast, brown spot diseases and yield component in rice at Rice Research and Training Center Experimental Farm, Sakha, Kafr El-Sheikh, Egypt. Theeffect of different sources of silica on the behavior and infection by rice blast on Sakha 101 rice variety had been studied in thefirst experiment. While the second experiment included the behaviorand infection bybrown spot of Egyptian Hybrid Rice One under silica nanoparticles biogenic treatments. The silica treatments were white rice husk, rice husk nanoparticles, white rice straw, rice straw nanoparticles, Mg2O8 Si3, and K2 SiO2. Chemicalfungicides (Beam and Del-Cup) and tap water were used as control. Different biogenic and chemical silica led to decreasing blast disease infection in Sakha 101 compared with control (tap water). Most of the agronomic characters of Sakha 101 were affected significantly by different treatments. All treatment of different biogenic and chemical silica sources decreased the leaf infection percent and severity for brown spot disease on Egyptian Hybrid Rice One. Different treatments significantly affected panicle length, number of filled grains per panicle, number of unfilled spikelets per panicle, 1000-grain weight, and grain yield and harvest index of Egyptian Hybrid Rice One. The result of this study suggests that silica caused decrease the intensity of blast and brown spot diseases.

Chicory (Cichorium intybus L.) related to the family Asteraceae is a winter crop and stores inulin in the taproots. Chicory is considerable a cash crop, whereas inulin is a polyfructans, which is widely used as prebiotic, sugar replacer, fat replacer, starting material for fructose syrup and oligofructose in several industrial applications.Thus,two field experiments were carried out in 2014/2015 and 2015/2016 seasons at El-Giza Agricultural Station Agricultural Research Center in Egypt (latitude of 300 03 N and longitude of 310 13 E) in a clay soil to evaluate the performance of two French chicory varieties namely Nues and Eurobees for its growth, yield and quality under three harvest ages 125, 145 and 165 days after sowing date in (October 15th in the two growing seasons). The experimental design was split plots with four replications. The results indicated that the two chicory varieties differed considerably concerning their potential of growth, yield and quality characteristics. Eurobees variety surpassed Nues in root formation, root fresh and dry yields/fed, inulin% and inulin yield/fed.Delaying harvest ages from 125 to 145 and up to 165 day after sowing caused significant increases in fresh and dry root yields/fed, inulin % and inulin yield/fed in both seasons. The interaction between Chicory varieties and harvest ages indicated that Eurobees achieved the highest significant values of root fresh, root dry and inulin yields/fed with delaying harvest age to 165 days after sowing as compared to Nues variety harvested at 125 days. Both Eurobees and Nues varieties which harvested at 165 days from sowing attained the highest significant variance of inulin% as compared to them at 125 and/or 145 days after sowing.As for enzymetic analyses of inulin extracted from sample of root dry at the three harvesting ages under this work indicated that Eurobees has the longest inulin chain length, while Nues was the shortest inulin chain length. Thus, the variation in quality traits of the two chicory varieties allows a wide spectrum of utilization in food and pharmaceutical industries in Egypt. Under conditions of this present work, it could be recommended that both root chicory varieties sowing in October and must be harvesting at 165 days after sowing to get the highest yields of fresh and dry roots as well as inulin% and inulin yield/fed, also for highest total fructose, reducing sugar percentages.

This investigation was carried out on female Jojoba (Simmondsia Chinensis, (Link) Schneider) shrubs in a private orchard at Hackstep, Zone, Cairo Governorate to evaluate 15 female shrubs, about 8 years old during two successive seasons of 2014 and 2015. The shrubs growing in sandy soil in 4 lines at distances 3 × 3 meter apart and irrigated with drip irrigation system. Through the rigorous assessment of female selected jojoba trees through the measurements of vegetative growth, floral measurements, productivity and the percentage of oil in their seeds. The study recommends the following: Firstly: the strongest shrubs were No. (1, 2, 5, 9, 10, 12 and 15), secondly: the shrub number No 4 was the earliest one in the flowering date in both first and second seasons. Thirdly: the highest yield recorded for female shrubs No. (5, 10, 12 and 15) in the first season, while in the second one were No. 9 and 12 per the branch. Fourthly: the female shrubs No. (2, 5, 7 and 13) gave the highest oil content in the first season, while in the second one, the female shrub No. 11 was the best. Fifthly: genetic fingerprint of different species was made using 15 primers and it resulted in 5 positive primer and unaffected 10 then, when using ISSR marker the results showed that there are differences between breeds. It is clear from the foregoing that the shrubs No. 5,4,12, and 11, 13) were the best in the strength of growth, early harvest, production and oil content percentage and can be more vegetative and cultivated. As for a high value of genetic similarity was No. 8 and 6 and also, the highest similarity value (0.875) was found between the strains (T8 and T6) followed by 0.792 between (T5 & T15, T8 & T13 and T11 & T14), respectively. Generally, genetic similarity value was low among the investigated genotypes and the study.
