These experiments aimed to evaluate the effect of some combinations among four plant densities (20, 30, 40 and 60 plants/m2) with four types of chemical compounds (its symbols i.e., chemical compound 1, 2, 3 and 4) beside the control treatment on growth, yield and pods quality of snap bean (Phaseolus vulgaris L.) cv.Polista as a famous variety, grown under open field conditions. This study aimed to introduce a practical solution to resist atmospheric changes and instability in temperature and especially sudden sharp recursively during growth and fall season. All studied densities gave rise to a positive effect on plant growth expressed as plant height, number of branches per plant, number of leaves per plant, leaf area per plant, foliage fresh weight and foliage dry weight per plant compared with control treatments. Positive impact in comparison with the treatments of the promo, which recorded the highest values of vegetation such as plant height, number of branches per plant and number of leaves / plant when growing 40 plants/m2 and using chemical compound 2, while cultivating 30 plants/m² with chemical compound 1 gave the highest values of fresh and dry weight, Leaf area and the stem diameter. Regarding the influence of interference on the pod weight in the first season only, the length of the pod and the number of pods/plant in both seasons did not show any differences moral consequences, while cultivating 30 plants/m² with chemical compound 2 gave higher values for the pod weight in the second season, the length of the pod and the total yield, if using 30 plants/m² with chemical compound 1 record higher values for the pod thickness. Regarding the chemical content of the leaves as chlorophyll, nitrogen, potassium, recorded the highest values when growing 30 plants/m² with chemical compound 2, except the highest phosphorus values when planting 30 plants/m² with chemical compound 1. Also treatment 30 plants/m2 with chemical compound 1 gave higher values for the content of vitamin C, TSS and less fiber content and acidity and therefore get the high yield plus high quality.Beni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17961120190601Evaluation of Chrysanthemum morifolium cv.

Maghi plants caused by Sodium Azide (SA) treatments. Shoot apical cuttings were dipped in the SA solution, at 0.0, 0.12 and 0.18% for two different soaking times (6 and 12h). The cutting survivability was immensely hampered (P˃0.05) due to the SA concentrations and the time of the treatment.<br />In both seasons, there were remarkable variations in the range of all investigated traits due to the SA treatments such as plant height, number of branches and flower heads/plant, Flower head diameters and their fresh and dry weight. However, number of days till full blooming showed the lowest variation. All SA-treated plants had higher PCV and GCV than the control ones for all investigated traits except days to full bloom and flower head fresh weights. Moreover, The PCV was always higher than GCV for all the characters. Almost all traits had higher heritability. However, there were huge differences in heritability values between the control and SA-treated plants. Presence of narrow gap between phenotypic coefficient of variation and genotypic coefficient of variation for many the characters under the study suggested that expression of these traits studied showed low environmental influence, which provide ample scope for selection of superior and desired mutants.Beni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17961120190601Biological control of subterranean termites (Psammotermes hypostoma ) by entomopathogenic fungi21295398510.21608/sjas.2019.53985ENMahmoudSomalian1Department of plant protection, Faculty of Agriculture, Beni-Suef University, Beni-Suef, EgyptRafatKhalaph Allah2Department of Botany (Microbiology), Faculty of Agriculture, South Valley University, Qena, EgyptMohamedHammadDepartment of plant protection, Faculty of Agriculture, South Valley University, Qena, EgyptKhaledEbnalwaledDepartment of physics, Faculty of science, South Valley University, Qena, EgyptJournal Article20190519This study is conducted to determine the effect of entomopathogenic fungi Metarhiziuim anisopliae ( M. ani), Beauveria bassiana (B.bas) and Aspergillus niger (A.niger) in some aspects subterrenene termites life under laboratory and field conditions . After one week of treatment there was significate difference among concentrate 4×106 and concentrates 2×106 and 1×106 but no significate difference among concentrates 2×106 and 1×106 of all treatments. In addition to there was significant difference among M.anisopliae and other fungi B.bassiana (Ballsamo) and A.niger, The fungi M.ansiopliae more effectiveness than B.bassiana and A.niger which the mortality rates were 22.5%, 15.0% and 13.3% to M.ansiopliae , B.bassiana and A.niger respectively. The LC50 for three fungi were 3.278×106, 4.6526×106 and 5.4982×106 for M.anisopliae, B.bassiana and A.niger, respectively. The higher concentrations 2×106spores/ml and 4×106 spores/ml the reduction percentages were 25.93, 19.43 and 11, 85% for 2×106 spores/ml and 61.52, 35.54 and 20.06% at 4×106 spores/ml for A.niger, B.bassiana and M.anisopliae, respectively . The run-down in the reduction % in treated traps with M. anisopliae concentrations of may be due to this reason. The reduction percentages for trap treated with concentrations of A. niger were height due to not attack by workers, due to the fungi A. niger has a repellent or an antipathetic effect to worker.Beni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17961120190601Efficiency of Agroecosystem Compounds against the desert locust Schistocerca gregaria (Forskal) and the African migratory locust Locusta migratoria migratorioides (Reiche and Fairmaire)30375419610.21608/sjas.2019.54196ENMahmoudSolimanPlant Protection Department, Faculty of Agriculture , Beni-Suef University, Egypt.Karem M.MohannaPlant Protection Department, Faculty of Agriculture, South Valley University, Qena, Egypt.Tharwat T.A.Abdel-FattahHead researcher of plant protection research institute (PPRI), Locust and Grasshoppers Department.

One day old 5th nymphal instars of each of the mentioned species were treated by various concentrations of tested compounds by the feeding technique. The results indicated that Locusta migratoria migratorioides is more sensitive to all tested insecticides than Schistocerca gregaria. In both species, fipronil was the most effective followed by spinosad, and chlorantraniliprole was the least effective. LC30 concentrations of the three compounds were used to treat the 5th instar hoppers of both species to examine the effects of sub lethal concentrations of the mentioned insecticides on the haemolymph total proteins, total lipids and total carbohydrates. It was found that haemolymph proteins, lipids and carbohydrates contents were dramatically reduced for the treated hoppers when compared to the untreated ones of both species. Malformed hopper and wrinkled winged adult were seen in insects treated by sub lethal concentrations of fipronil and spinosad.Beni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17961120190601Effects of Lipidium sativum seeds extract (Garden cress) on the kidney in sodium nitrite receiving rats38455281810.21608/sjas.2019.52818ENEnas S.Abdel-BakyLecturer of Zoology, Biology department, Faculty of education- Ain Shams University, Egypt. corresponding author: e-mail: enashelal5566@yahoo.comJournal Article20191010This study was carried out to investigate the modulating effect of Lipidium sativum (LS) seeds aqueous extract consumption against sodium nitrite (SN) that induced the nephrotoxicity in male rats. Rats were divided into four groups. Group 1 (control): without any treatment; group 2: injected with a single dose of SN (50 mg/kg body weight) 24 h prior to decapitation intraperitoneally (i.p.); group 3: given orally 300 mg/kg body weight of LS for four weeks; group 4: treated orally with LS for four weeks, then injected with a single dose of SN, at 24 h prior to decapitation (i.p.) with the same doses. The results showed that, the treatment with sodium nitrite revealed a significantly increase in the levels of sodium, chloride, total calcium, ionized calcium, urea, creatinine and uric acid comparing to the control group. In respect to serum potassium, there is a significant decrease when compared to the control group. Also, the kidney tissue thiobarbituric acid reactive substances (TBARS) were significantly increased. But the superoxide dismutase (SOD), glutathione (GSH) and Catalase (CAT) enzymes were markedly decreased. The pre-treatment with LS before the injection of SN improved the harmful effects of SN caused in the serum levels of the biochemical parameters tested and the concentrations of GSH, SOD, CAT and TBARS in the kidney tissue comparing to SN-treated rats. It could be concluded that Lipidium sativum seeds act as a natural substance for ameliorating the alterations in serum electrolytes, kidney function and oxidative damage induced by sodium nitrite in the kidney tissue.Beni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17961120190601Economic implications of the shift towards the cultivation of protected vegetables46535398610.21608/sjas.2019.53986ENTamer M.ElsentrecyAgricultural Economics Department, Faculty of Agriculture, Beni-Suef University, Beni-Suef, Egypt.Journal Article20190514The shift towards the cultivation of vegetable crops through protected agriculture is one of the main axes of increasing agricultural production and providing some agricultural land and water, as well as a positive impact on both farms and the national economy.<br />The green vegetables, green pea, cabbage, zucchini, lettuce, spinach and cantaloupe are cultivated in a protected area of 5.7 thousand feddans only, with a yield of more than three times that of agriculture Exposed.<br />As the mentioned crops are grown in the three lagoons in an area of 1232.2 thousand feddans and achieved a production of about 14166 thousand tons, representing 66.5% of the total vegetable crops exposed in the three queens. The study estimated that the same production can be achieved through protected crops in about 133.4 thousand feddans in the three soils, thus saving about 276.7 thousand feddans can be cultivated with the same quantities of water and the same cost by following one of the agricultural courses<br />The study showed that the production of 276.7 thousand feddans in the cycle of beet sugar + summer potatoes achieved the highest yield of about 5859 million pounds at local prices. It also contributes to reducing sugar imports by 3.26 billion pounds annually.<br />The cultivation of 133.4 thousand feddans in green vegetables in the three lagoons, taking into consideration the costs of protected agriculture, including the cost of constructing the house, will yield a net return of more than the equivalent of open agriculture by 7.94 billion pounds annually, representing about 6.76% of total agricultural agricultural income in 2016/2017..<br />The study pointed out that this shift towards the cultivation of protected vegetables to achieve production from open agriculture will entail the provision of about 400.2 million cubic meters of water per year that can be directed to the reclamation and cultivation of new lands.<br />The study showed the end of the study compared to some economic indicators of open agriculture and protected agriculture for vegetables in feddan without taking the revenues from the cultivation of 276.7 thousand feddans in the cycle (beet sugar + summer potato) in consideration.<br />KEYWORDS: Green vegetables, Agricultural greenhouse, Feasibility
