The effect of various thermal treatments (electric oven, microwave) and g-irradiation at three doses (6, 8 and 10 KGy) on the composition of volatile and non-volatile of anise essential oil and also their antioxidant properties were considered. The hydrodistilled oil (HD) of control and treated samples were subjected to gas chromatography–mass spectrometry (GC/MS) analysis. The volatile profile of raw HD oil of anise consisted mainly of transe-anethole (79.68%) followed by hexahydrofarnesyl acetone (6.95%), para-anisaldehyde (5.49%); g-himachalene (2.53%) and estragole (0.76%). Although the effect of roasting didn’t cause significant changes in the total yield  of major compounds of HD anise oil which are phenylpropanoid derivative (transe anethole , para-anisaldehyde, cis-anethole and estragole (=methylchavicol), it is found that gamma irradiation revealed the same behavior at the 10 KGy irradiated sample but decrease the total yield of these compounds in 6.8 KGy irradiated sample compared to control one. also the thermal and g- irradiation caused drastic increase in the total yield of sesquiterpenes whereas decreased oxygenated compounds  in all samples under investigation compared to control one. Such changes affected the antioxidant activity of the treated samples 1.1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging as well as β-carotene bleaching test against butylated hydroxy toluene (BHT). The strongest effect of reduction of DPPH radical as well as the highest inhibiting effect of the oxidation of linoleic acid and the subsequent bleaching of β-carotene was by 8 KGy irradiated sample which comprised (84.57%±1.43); (85.21% ± 0.12) respectively, in comparison to BHT (98% ± 0.0) at the same concentration 30 µg/mL besides all samples under investigation revealed high antioxidant activities due to their high content of phenylpropanoid and oxygenated compounds. These confirmed by total phenolic content.  High performance liquid chromatography (HPLC) method was used for the analysis of phenolic compounds in the selected sample. Polyphenolic compounds were analysed on C18 Reversed Phase (RP) HPLC. A total of 9 phenolic compounds were identified, the obtained results showed that the predominant compound was P-qumaric acid (43.36%) followed by ferulic acid (21.06%).

Two field experiments were carried out during two early summer seasons of 2012 and 2013 years at the Experimental Farm of Kaha Station, Qalubia Governorate to study the response of snap bean plants Poulista c.v to some agricultural treatments for early green pods yield production using (flowering, amcotone, super phosphate solution compounds) as foliar nutrition, (charcoal, agriculture sulphur and charcoal + agriculture sulphur) as soil addition and( Pea, onion and broad bean) as protection plants, in addition using black polyethylene plastic as a soil mulch. The results indicated that spraying the plants with flowering and amcotone compounds followed by super phosphate solution had the highest values of fresh and dry plant weight. While addingcharcoal to the soil before sowing snap bean seeds gave the highest values of no. of leaves/ plant followed by spraying withflowering and amcotone compounds, respectively. The data showed also that spraying the plants with flowering, amcotone compounds, super phosphate solution, adding charcoal + sulphur and soil mulch with black polyethylene plastic exerted the highest values on all parameter of  green pods its and yield attributes in both growing seasons. Concerning total sugars in dry pods it's clear that using protection plants with broad bean followed byonion were the best treatments on it. Generally it can recommend  using  any one of the mentioned treatments in this experiment especially flowering, amcotone compounds, super phosphate solution, charcoal + sulphur, respectively to obtain high green pod yield  either early or total with the  best quality.

Morphological structure and different characters of achene is most important from the taxonomic point of view. In present study achene shape, colour, size, texture and pappus type were recorded for 20 taxa of Asteraceae by using light microscope (LM) and scanning electron microscope (SEM). Examination of pappus by SEM recorded 6 groups; (1- Scarbous barbellate fine bristles and scarbous barbellate bristles, 2- Scarbous subulate scales free, 3- Scarious scales, 4- Paleaceous scales corona, 5- Plumose bristles and 6- Capillary barbellate). Also eight patterns were recognized based on surface sculpturing pattern: reticulate, with two subtypes, tuberculate, sulcate, puncticulate, colliculate, aculeate, lineate and striate. The data proved useful in the construction of a dichotomous indented key to the studied taxa. Twenty-two characters with 85 characters stats were used to generate anatomical key using the DELTA key-generating programs.

Sixteen flax genotypes {13 promising lines and 3 check varieties viz., Giza 8 (oil type), Sakha 1 (dual purpose type) and Sakha 3 (fiber type)} were evaluated for straw, seed, oil yields and their related traits under twelve different environments; four locations (Sakha, Etay El-Baroud, Ismailia and Giza Exp. Stations through three successive seasons (2011/12, 2012/13 and 2013/14). These materials were evaluated in a randomized complete blocks design with three replications at the twelve above-mentioned environments. The analysis of variance revealed highly significant differences among genotypes (G), environments (E) and G x E interaction for all studied traits except straw weight per plant, indicating a wide range of variation among genotypes, environments and these genotypes exhibited differential response to environmental conditions. The significant variance due to residual for all characters except both straw weight per plant and oil yield per fad indicated that genotypes differed with respect to their stability suggesting that prediction would be difficult, which means that mean performance alone would not be appropriate. Interaction component of variance (σ2ge) was less than the genotypic variance (σ2g) for all characters, indicating that genotypes differ in their genetic potential for these traits. This was reflected in high heritability and low discrepancy between phenotypic (PCV) and genotypic (GCV) coefficients of variability values for these traits indicating the possibility of using each of long fiber percentage, plant height and technical stem length as selection indices for improving straw weight per plant, as well as, using 1000-seed weight and capsules number per plant as selection indices for improving seed weight per plant. Yield stability (YSi) statistic indicated that S.541-C/3 and S.541-D/10 gave high mean performance and stability for straw, fiber, seed and oil yields per fad in addition to oil percentage, capsules number per plant and 1000-seed weight. Therefore, the two genotypes well be released under the name Giza 11 and Giza 12, respectively. These newly released varieties are of dual purpose type for straw, fiber, seed and oil yield. They may replace the low yielding cultivars Giza 8, Sakha 1 and Sakha 3.

Susceptibility of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera : Gelechiidae) larvae, pupae and adults to entomopathogenic nematode, Steirnernema carpocapsae and two fungal species; Beauveria bassiana and Metarhizium anisopliae was investigated under laboratory conditions. Applied concentrations against the last instar larvae and different ages of the pupae, using leaf and soil treatments, were 250, 500,1000 IJs/ml for the nematode and 108, 109,1010 spores/ml for the fungi. Soil applications of the nematode and fungi resulted to high mortality (100, 100 and 93.3%) of4thinstar larvae while low pupal mortality (46.7,30and 23.3% ),respectively. In leaf treatment a high level of larval mortality (93.3, 90 and 80%) was recorded revealing S. carpocapsae, B. bassiana and M. anisopliae, respectively. The present study also showed also susceptibility of Tuta absoluta adults to the three pathoens. The results demonstrated suitability of entomopathogenic nematode and fungi for controlling T. absoluta.

Two field experiments were conducted at the Experimental Research Farm, Faculty of Agriculture, Suez Canal University, Egypt during spring 2013 and 2014 using summer squash (Cucurbita pepo cv. Eskandarani) for studying the effects of PGPR strains. The objective of the first experiment was to study the efficiency of single, double and triple inoculations of Azospirillum brasilense (AC1), Bacillus subtilis (AC2) and Serratia marcescens (BM1) on summer squash fruit characters. Results showed that the double inoculations of tested PGPR strains in addition to single inoculation with Serratia marcescens produced non-significant higher fruit yield and average fruit weight compared to triple inoculation (AC1+AC2+BM1) and single inoculation with Azospirillum brasilense. However, non-inoculated control plants and plants inoculated with Bacillus subtilis showed lower fruit yield and average fruit weight. From the previous results, it concluded that the double inoculation were better than single and triple inoculations. However, the aim of the second experiment was to evaluate the efficiency of PGPR under N and P fertilization levels on plant growth, yield and nutrients uptake of summer squash as well as soil nutrient availability (available N and P). As per main effects, generally, plant growth, fruit yield, nutrients uptake and availability enhanced significantly by increasing N and P levels, except half dose of P which gave statistically equivalent values of plant fresh and dry weight as well as nitrogen uptake in shoots and fruits in addition to P in shoots compared to full dose. Also, main effect of PGPR showed that the inoculated plants gave significantly higher plant growth, fruit yield, nutrient uptake and availability compared to un-inoculated control plants. Inoculated plants with PGPR strains under full dose of N and P gave mostly highest plant growth, fruit yield, nutrients uptake and availability. This effect was at significant level in terms of fruit yield, soil nutrient availability and some nutrients uptake such as K in the shoots and N the fruits. Furthermore, PGPR significantly reduced P fertilizer application without any reduction in squash yield, especially under no and half dose of N fertilizer. Results revealed that the efficiency of PGPR strains increased by P increasing and decreased by N increasing.

This study was carried out to investigate the effect of partial substitution (10 and 15%) of wheat flour by sorghum or chickpea flour on quality parameters of sponge cake and biscuit. Chickpea flour contained the highest percentage of protein, lipids, ash and crude fiber. Water absorption was increased by replacement of wheat flour with sorghum or chickpea flour. From the obtained data, it could be seen that the deleterious effect of adding sorghum flour to wheat flour on the rheological properties was more pronounced than that happened when chickpea flour was added. Cake prepared with sorghum flour had less pronounced improvements in its chemical composition rather than those of chickpea. With regard to volume and specific volume, cake prepared with 10% chickpea flour with or without cake improver recorded the highest values. Cake prepared by chickpea flour had no any unfavorable sensory change especially for the cake produced by cake improver.  Crude protein, lipids, ash and crude fiber contents were increased progressively in all biscuit samples with increasing of either the sorghum or chickpea flour levels. Also, there were no significant differences (P>0.05) between the thickness and spread ratio of control biscuit compared to that of sorghum or chickpea- wheat composite flour.  It is worth mentioning that the substitution of wheat flour with chickpea flour gave biscuit more sensory acceptable.

The present investigation was carried out at the Experimental Farm of the Faculty of Agriculture at Fayoum, Cario University at Dalla, Fayoum Governorate during the two seasons 2000/2001 and 2001/2002. The aim of this investigation was to study the effect of organic manure and number of berseem cuts on cotton yield and its components and fiber traits. The obtained results indicate that only plant height at harvest, number of fruiting branches / plant and the height of the 1st fruiting branch were significantly affected by organic manure (O.M.) application. On the other hand, organic manure did not affect significantly the seed cotton yield, yield components and fiber quality traits. Cotton planting dates affected significantly all studied vegetative growth, seed cotton yield, yield components and fiber quality traits. Early planting date (1st week of March) showed significant superiority over the other two planting dates (1st week of April & May) in number of fruiting branches/ plant, number of days to 1st flower appearance and 1st boll opening, number and weight of open bolls/ plant in the 1st& 2nd pickings, seed cotton yield, lint percentages and studied fiber quality traits. The decreases in the total seed cotton yield attributed to the late planting dates (1st week of April & May) amounted 26.4 and 84.8% and 30.6 and 84.1% of  March planting with the treatments of 10 and 20 m3/ fad organic manure, respectively.

Two field experiments were carried out during two summer seasons of 2013 and 2014 years at the Experimental Farm of Kaha Station, Qalubia Governorate to study the effect of using three irrigation intervals (7, 15 or 21 day) and five treatments of water absorbent substrates as adding to soil before transplanting ,i.e. (without substrates (control), SAP at 15 kg/fed., SAP at 20 kg/fed., compost at 5 t/fed. and compost at 10t/fed.) on sweet  pepper plants c.v. Mohanad and the effect of that on growth, yield, physical and chemical characters of sweet  pepper fruits. The results indicated that, the highest values of all vegetative growth parameters, yield and yield components were registered by the treatment of 7 days or 15 day irrigation intervals. Concerning of using water absorbent substrates, it was found that, pepper plants grown in the soil fertilized at 10 t/fed. or treated with super absorbent polymer (SAP) 20 kg/fed., respectively gave the highest values of vegetative growth parameters, yield and yield components.It is obvious that the plants fertilized at 10 t/fed. and irrigated every 7 days gave the highest values of fruit length, fruit diameter, fresh fruit weight and total yield. While, plants treated with SAP at 20 kg/fed. and irrigated every 15 day gave the highest values of fruit diameter and fresh fruit weight, but the differences did not reach to significance level for fruit length and early yield in both growing seasons. On the other hand, compost at 10 t/fed., compost at 5 t/fed. and SAP at 20 kg/fed. with irrigation every 21 day were the best treatments for yield and yield components of pepper plants. Generally, it can recommend by using compost at 5 t/fed., or super absorbent polymer (SAP) at 20 kg/fed. with irrigation every 15 days and this mean that increased the irrigation period without any injury or statistical effect on the fruit crop to obtain high pepper fruit yield  with height quality and height net income to the growers.
