: Accelerating global warming and water scarcity and improving water use efficiency are considered essential factors for achieving adequate crop development and productivity. Therefore, the authors targeted the use of arbuscular mycorrhizal fungi (AMF) and Pseudomonas fluorescens (Ps1) for improving growth, productivity, and water use efficiency of broccoli plants ( Brassica olercea L. var. italica , cv. Belstar F 1 ) under various irrigation regimes i.e., 50, 75, and 100% of crop evapotranspiration (ETc). Two greenhouse experiments were carried out in clayey soil. The combined inoculation of endomycorrhizae and Ps. fluorescens (Ps1) improved water use efficiency and consequently vegetative growth and yield. Under the applied irrigation regime 75% ETc of broccoli inoculated with both endomycorrhizae and Ps. fluorescens (Ps1) showed higher head weight (616 and 647 gram) than those grown under the irrigation regime 75% ETc combined with endomycorrhizae
:加速全球变暖和缺水以及提高用水效率被认为是实现充分作物发展和生产力的基本因素。因此，作者瞄准了利用丛枝菌根真菌(AMF)和荧光假单胞菌(Ps1)来提高西兰花(Brassica olercea L. var. italica, cv.)的生长、生产力和水分利用效率。在不同的灌溉制度下，即50%、75%和100%的作物蒸散量(等)。在粘性土壤中进行了两个温室试验。联合接种内生菌根和荧光ps (Ps1)提高了水分利用效率，从而提高了营养生长和产量。75% ETc同时接种内生菌根和荧光ps (Ps1)的西兰花在灌水条件下的穗重(616和647 g)高于75% ETc同时接种内生菌根的西兰花

: This study aimed to examine the consequences of three regimes for irrigation on cucumber crops and their growth indication, production, and water productivity under greenhouse cultivation. Cucumber seedlings were planted in May 2018 under a greenhouse condition. Three regimes of drip irrigation were examined, first 100%, 80%, and 50% of ETc namely T1, T2, and T3, respectively. Second regime was systems of drip irrigation (surface and sub-surface irrigation), finally the third is drippers discharge which used (2 l/h and 4 l/h). Results indicated clearly that the best production was under 80% ETc regime by 2 l/h dripper for surface and subsurface that was 10.1 and 11.2 ton/greenhouse respectively with IR 172 m 3 /season and the best regime by using 4 l/h was 50% ETc for surface and sub-surface respectively which was 11 and 11.5 ton/greenhouse with IR 216 m 3 /season which saved about half a quantity of irrigation water. On the other hand, the very best water productivity value (WP) was under 80% ETc was 58.7 and 65.4 kg/m 3 under surface (S) and sub-surface (SS) drip irrigation respectively by 2

: Study was conducted to assess two enzyme detoxifying activities and insecticide-resistance gene expression quantitation using real-time (PCR). Four populations of pink bollworm were compared with baseline laboratory strain. Field populations showed higher levels of enzymatic activity, glutathione-S-transferase and β–esterases, than those of the laboratory strain. The amplification curves scored a cycle threshold ( Ct ) value of 25 for the ribosomal protein subunit7 ( rps 7). For the BtR gene, the Ct values of analyzed biological groups ranged from 20 for laboratory strain to 24 for Fayoum group. For Cad1 , the Ct values ranged from 19 for laboratory strain to 23 for Fayoum and Qalubia populations. Therefore, the present work intro-duces a method for the challenge of monitoring resistance to Bt toxins in crops which require, according to IPM (Integrated pest management) pro-gram,

: In the sake of enhancing the thermal stability of α-Tocopheryl acetate (α-TA) and Strawberry Anthocyanins (AN), their encapsulation with starch or β-Cyclodextrin were prepared and characterized by UV-Vis and IR spectra in addition to thermal analysis. Thermal stability was investigated by comparing the thermographs of each host and guest with that of the prepared complex. Both hosts provided extra thermal stability to both guests where α-TA is stabilized from 230 to 291 o C by complexation with starch and to 285 o C by encapsulation with β-CD. AN was also stabilized from 40.02 o C to 75.57 and 79.46 o C by complexation with starch and β-CD respectively.

Adjuvant, Biochemical parameters, Calves, FMD, Humoral immunity, Vaccine Abstract: The foot and mouth disease (FMD) vaccine is used to control the FMD in cloven-hoofed animals including calves. The most important step in vaccine preparation is the selection of a suitable adjuvant which plays a main role in the vaccine’s potency. The present study is an attempt to use clinoptilolite instead of Montanide oil to enhance the efficiency of the FMD vaccine and reduce its production cost. Twelve calves were split into four groups. Three groups were vaccinated with FMD vaccine with different adjuvants i.e. 100% Montanide (ISA 206), 50% of Montanide with 1.0 μg/dose of clinoptilolite (ISA 206+CLINP), and by replacing the 100% of Montanide by 1 μg/dose of clinoptilolite (CLINP). The fourth group was unvaccinated. Results showed that calves vaccinated with (ISA 206+CLINP) FMD vaccine expressed the highest and the longest periods of immune response until 38 weeks. While groups vaccinated with (CLINP) or (ISA 206) vaccine showed only protection up to 26 and 34 weeks respectively. Also, our results showed that clinoptilolite improved organ functions resulting from the stress of vaccines. Finally, this study recommended the use of clinoptilolite with Montanide oil as a potential adjuvant in the FMD vaccine to give high stimulation of the immune response.

: Glyphosate (GLY) and glufosinate ammonium (GLUA) are broad spectrum, non-selective, contact herbicides which are commonly used in fruit farms. Achieving the separation and detection of glyphosate and glufosinate from soil samples by chromatograph are a challenging task as they are ionic and highly water soluble compounds. The aim of this study is conducted to determine the dissipation of GLY and GLUA applied at two dose levels in three depth soils of orange orchards. The residues of GLY and GLUA were determined by HPLC-UV detector. The residual detection limit of GLY and GLUA of the method were 0.03 and 0.05 ng/g in soil respectively. The obtained data indicated that GLY persistent in soil is very short, only for 7 days, following applications of 1 to 2 kg/fed in orange crop. GLUA dissipated in soil within 14 days of application, regardless of dose. The half-life (T/2) of GLY and GLUA were 1.68 and 1.42 days in at 0 cm depth, respectively. There was no significant difference between the half-life of the two herbicides in soil at three depths. These results showed that GLY dissipation

: A series of lab and field experiments were carried out to evaluate the possibility of using some substances as adjuvants added to the foliar fertilizer tank to improve fertilizer application and use efficiency. Each of the suggested substances was prepared in 10 concentrations treatments, ranging between 0.05 and 2g/L. The effect of each concentration on static surface tension and static contact angle in liquid/air/glass and solid plant leaves/air interface were used to evaluate and find out the optimum concentration of each substance to be used as adjuvant. An Adjmix-D1 was prepared using 0.6g/L Triethanolamine and 0.6g/L liquid soap as surfactants, 0.6g/L glycerin as a humectant, 0.6 g/L Arabic gum as a sticker and 0.6g/L urea as a penetrator.

: Pot experiment was carried out in seventeen levels of fertilization to evaluate the effect of the bio-fertilizer mixture alone or in combination with chemical fertilizer (NPK) on Fennel ( Foeniculum vulgare Mill). Biofertilizer was a mixture of Azotobacter chroococcum , Bacillus circulans and Vesicular-arbuscular mycorrhiza. Results indicated that use of bio-fertilizer at 3.75 ml/pot four times with 25% of NPK gave the highest significant values of vegetative growth, yield parameters, and also NPK uptake; however, fertilizing with bio-fertilizers without NPK application showed the lowest significant values in the two experimental seasons. The same addition of biofertilizer gave the highest significant values of total microbial count of soil and increased cumulative CO 2 ; whereas addition of 100% NPK gave the lowest significant values in both seasons. The full dose of NPK significantly increased volatile oil percentage while the addition of bio-fertilizer only significantly decreased it in both seasons. GC analysis of essential oil showed that the highest percentage of anethol (12.77 %) was obtained by applying 3.75 ml/pot bio-fertilizer added one time + 25% NPK and decreased estragole (72.78%).
