The present work was carried out during the two seasons of 2019 and 2020 in Al-Marashda Research Station, Qena Governorate, Egypt. This experiment was conducted to examine the possibility of producing Melia azedarach L. as a valuable trees under salinity stress by using yeast extract levels as bio fertilizers. The layout of the experiment was sitting as completely randomized in a splitplot design with two factors (salinity and yeast extract with two controls) and included 16 treatments; 4 levels of salinity (0, 2000, 3000 and 4000 ppm) and 4 levels of yeast extract (0, 5, 10 and 15%). Results indicated that the different vegetative growth characters as well as chemical constituents of M. azedarach were decreased due to various salinity concentrations. Foliar application of yeast extract with salinity levels increased of vegetative characters and chemical composition compared to the control. Meanwhile, the exogenous application of yeast extract showed a significant reduction in values of free proline content in leaves of M. azedarach and this decrease was higher with spraying 15%, in the average of seasons. These results assure the possibility of growing M. azedarach seedlings at the same conditions of salt stress by the use of some bio fertilizers as yeast. Accordingly, these trees can be planted in newly reclaimed soils and afforestation programs in areas that affected by salinity with spraying by yeast extracts at 15%.

Bioactive food compounds (BFCs) are micronutrients existing in small quantities in various foods. Plant, microbes, and animals are considered the main sources of bioactive components including polyphenols, flavonoids, ω-3 FAs, and so on. BFCs have many biological functions such as antioxidant, antidiabetic, antiobesity, anti-cardiovascular, anticancer, antiinflammatory, antimicrobial, immune-modulatory, cholesterol reduction characteristics, and others. However, incorporation of BFCs in food or pharmaceutical formulations is limited because of their high liability against temperature, pH, shear, pressures, and light, as well as poor hydro-solubility in some of these compounds, low stability under human gastrointestinal conditions, and thereby lower bioavailability (BA) and reducing functional activity. Therefore, encapsulation of BFCs using micro/nanostructure systems can overcome these challenges. These encapsulation systems include nano-silver, nano-gold, nano-emulsions, liposomes, cubosomes, biopolymer-based nanoparticles, nano-gels, and so on. Finally, biopolymer-based nanoparticles and nano-gels are good choices to encapsulate the BFCs compared to other available encapsulation systems due to their advantages. Furthermore, encapsulation of BFCs in micro/nano-systems improved their bio-efficacy including antioxidant, antidiabetic, antiobesity, anti-cardiovascular, anticancer, anti-inflammatory, antimicrobial, and immune-modulatory. Among all encapsulated-BFCs, encapsulated-curcumin and -quercetin showed the highest bio-efficacy. However, further studies regarding stability, BA, and in vivo work of BFCs-loaded micro/nano-encapsulation systems are recommended to evaluate the therapeutic efficacy including physicochemical stability, target mechanisms, cellular internalization, and

Paclobutrazol enhances the productivity of lowland rice when applied during the second ratoon cropping. This study sought to determine the response of second ratoon lowland rice to paclobutrazol at different levels of application. Determine the specific level of paclobutrazol application that can produce maximum productivity, and evaluate the profitability of growing second ratoon lowland rice applied to paclobutrazol at different levels of application. The study was set out in a Randomized Complete Block Design (RCBD) with levels of paclobutrazol application as treatment and replicated three times. The paclobutrazol application treatments were; T 0 – no paclobutrazol application (control), T 1 – paclobutrazol at 50ppm, T 2 – paclobutrazol at 100ppm, T 3 – paclobutrazol at 200ppm, T 4 – paclobutrazol at 300ppm, T 5 – paclobutrazol at 400ppm, T 6 – paclobutrazol at 500ppm, and T 7 – paclobutrazol at 600ppm. Statistical analysis revealed that second ratoon lowland rice applied with 300ppm paclobutrazol (T 4 ) significantly produced a taller plant height, an abundant number of tillers hill -1 , greater LAI, higher percent of tall tillers with elongated panicles, higher fresh straw yield, longer root length, more number of nodal roots plant -1 , longer panicle length, abundant spikelets per panicle, and produced remarkably the highest grain yield when compared to unsprayed control. This treatment achieved the highest gross margin (USD764.11) than those other treatments adopted. This study enlightens the ratoon growers regarding the physiological biochemical responses of ratoon crops to the application of paclobutrazol as a growth regulator in enhancing rice productivity.

There is a gap in knowledge regarding the impact of trap depths on Psammotermes hypostoma ( Desneux) population variations. The purpose of this study is to investigate the impact of trap depths and some physical parameters on worker population fluctuations. From September 2019 to August 2020, 1300, El-Sebay-modified traps within Poly Vinyl Chloride (P.V.C.) tubes were used at several depths of 10 cm, to 150 cm in Qena City, Egypt. Furthermore, temperatures and relative humidity % were assessed using the Pearson correlation coefficient. The current findings illustrated the highest percentage (34.04%) at 10 cm depth, inversely, the lowest was (7.24%) at 100 cm depth. Interestingly, the 36 th week (April) at 50 cm depth had the highest mean number of individuals (234.60 ± 12.9). Although, at 10 cm depth, the lowest mean number of individuals was 0.20 ± 0.20 in the 19 th week. On the other hand, result analysis demonstrated that both maximum and minimum temperatures had a substantial positive effect on the worker activity at 10 cm depth where r = 0.333 and 0.318, respectively. However, there was a significant negative effect at 150 cm depth between the maximum, and minimum temperatures. Additionally, RH% had a significant positive effect at 150 cm depth and a negative significant effect at 10 and 50 cm depths, respectively. Thus, it's concluded that the abundance of individuals is inversely proportional to the soil depth furthermore temperature, and directly the relative humidity. So, in the future, this could be a viable result for managing subterranean termites.

The interest and development of logistics services have become the focus of attention of most economies in the world over the past decades. This is what called for Egypt's need to pay attention with the level of its logistical performance and relying on it as an effective solution towards the development of exports within it. Therefore, the study takes its importance by identifying the extent of the reflection of the development of logistical performance on the development of total and agricultural exports through the application to the COMESA agreement using the gravity model. The results showed that the most important factors affecting the total of Egyptian exports to the COMESA countries. It is represented in the gross domestic product of the importing country, the commercial openness to Egypt, the participation in the land borders, the per capita GDP of importing countries, in addition to the adverse effect of the geographical distance. The performance index of logistics services increases in Egypt with an increase in the GDP of Egypt.

The purpose of this study was to determine the toxicity of fenpyroximate, bifenazate, emamectin benzoate, buprofezin, sulfur, K. Z oil, and chili nanosilver (AgNPs) extract against the two-spotted spider mite ( Tetranychus urticae ) associated with tomato plants ( Lycopersicum esculentum ) during the summer cultivations of 2017/2018 and 2018/2019 seasons, The bioassay revealed that the tested pesticides were in the same order of efficacy at both the LC50 and LC90 levels. The pesticides that were tested could be sorted in the following order: fenpyroximate ˃ bifenazate ˃ emamectin benzoate ˃ buprofezin ˃ sulfur ˃ K. Z oil ˃ chili AgNPs extract. The corresponding LC50 values were 90.02, 112.18, 131.96, 154.60, 220.14, 269.48 and 314.44 ppm, while the LC90 values were 4403.98, 742.45, 756.11, 1293.59, 914.76, 1568.16 and 1500.05ppm, respectively. On the other hand, χ2 values were 2.09, 1.68, 2.65, 2.96, 2.75, 5.20, and 5.24 respectively. The field experiments show that fenpyroximate, bifenazate, emamectin benzoate, buprofezin, sulfur, K. Z oil, and chili AgNPs succeeded in controlling T. urticae , where the means of reduction percentages of infestation were 76.91, 67.00, 71.64, 55.54, 69.40, 64.96 and 72.23 % in 2017/2018 season, respectively. While the means of reduction percentages of infestation were 83.55, 80.55, 78.62, 77.30, 78.29, 73.20, and 72.37 % in the 2018/2019 season, respectively.

This study examined the inhibitors militating against artisanal fisherfolks in Epe Local Government Area, Lagos, Nigeria. A two stage sampling procedure was used to select 120 respondents. Data were obtained by the use of structured questionnaire. Based on the result of findings, most of the respondents were female (66.7%) with average age of 44 years. The average farming experience was 12 years. Tilapia and Croaker (mean=3.99), Catfish (mean=3.98), Obokun fish (mean=3.97), Pink shrimp (mean=3.91), Ejaosan (mean=3.88), Abo (mean=3.06) and Akokoni (mean=3.03) were highly harvested fish among respondents. The top ranked inhibitors were infestation of water by hyacinth (mean=2.67), inaccessibility to credit (mean=2.05), and inadequate technology (mean=2.02). Borrowing money (mean=2.27), Borrowing equipment (mean=2.05), Servicing boats before breakdown (mean=1.68) were the leading coping strategies to inhibitors against fisher folks in the study area. PPMC results show that sex (r=0.254; p=0.006), education (r=0.233; p=0.012) and primary occupation (r=0.357; p=0.000) were socioeconomic characteristics that significantly affect inhibitors against fisher folks in the study area. There is need for government to make fund available for arsenal fisher folks by creating loans through bank of Agriculture. Fisher folks should also be enlightened through extension programmes on how to control water hyacinth, improvement of fishing practices and technology adoption.

Manfalouty) fruits during two successive seasons, 2019 and 2020. Trees were treated with the vermicompost tea application by spraying fruits and leaves or adding them to the soil at a distance of 50 cm from the trunk of the tree, or a combination thereof, three times a year; the first one in the middle of July (after fruit set), the second after a month of the first application, and the last one after a month of the second. The results demonstrated that all treatments achieved the increment and improvement of all parameters compared with the control, while the treatment that included a combination of foliar application and adding to the soil gave the best effectiveness compared with the other treatments in the two successive seasons. It was also noted that the physical and chemical properties of fruits were better in the second season compared with the first, which was due to the accumulation of the effect of vermicompost in the soil. So the recommendation of this study is to use vermicompost either spray the trees or add to the soil. Both had a positive impact on fruits, while the best effect is to use a combination of both.

A study was conducted during 2018 and 2019 summer seasons at Toshka Agricultural Research Station, Agriculture, Egypt, with the objective to study the effect of sowing date and planting methods on productivity and oil content of three sesame varieties. The experiment was laid out in a split-split plot arrangement was based on a randomized complete block design (RCBD) with four replications. Sowing dates were assigned to the main plots while planting methods in sup-plot and varieties in sub-sub-plot. There was a significant effect of the interaction between sowing dates, sowing method and varieties on study traits (capsule length, capsule width, 1000-seed weight, seed yield per Faddan and seed oil content). The highest values of capsule length were obtained from the interaction of D 1 M 3 V 3 , capsule width from D 3 M 2 V 3 , number of capsules per plant from D 1 M 2 V 1 . The interaction D 2 M 2 V 2 gave the highest values of 1000-seed weight, seed yield per Faddan and seed oil content.

Sesame ( Sesame indicum L.) is being infected with various pathogens which cause severe losses in oil and seed production. This work aimed to identify the most tolerant cultivars to Fusarium oxysporum f. sp. sesami (Zap) Cast and Macrophomina phaseolina (Tassi) Goid, screening of cultivars for agronomic traits and study the path-analysis of yield and its components. Eight cultivars were evaluated in the field and in the green house under artificial infection of both pathogens for the seasons of 2018 and 2019. The combined analysis revealed significant differences among cultivars for most traits. Int 688 was the best cultivar in seed yield/plant (SY/P) under the infection of the two pathogens. The highest correlations were among SY/P, number of seeds/capsule (NS/C), 1000sw and number of capsules/plant (NC/P) at the genotypic level. Generally, the results of path-analysis indicated that both of NS/C and NC/P showed the highest direct and indirect effect on SY/P under the infection both pathogens. It could be concluded that restricted selection by NC/P and NS/C in the segregating generations of crosses among the tolerant parents from these materials could be improve seed yield. The reaction of the eight cultivars to the two pathogens in the green house indicated highly significant differences of susceptibility and resistance to Fusarium wilt and charcoal rot among the tested cultivars. Results indicated that Shandaweel 3, Int 688 and Giza 24 cultivars proved to be the most resistant cultivars; they produce the lowest percentages of disease severity of Fusarium wilt and Macrophomina damping-off and rot.
