Effect of Irrigation, Foliar Spray with Nano-fertilizer (Lithovit) and N-levels on Productivity and Quality of Durum Wheat under Toshka Conditions
Tow field experiments were carried out at the Experimental Farm of the Water Studies and Research Complex (WSRC) Station, National Water Research Center, in Abu Simbel, Toshka Region, Egypt during two winter seasons 2015-16 and 2016-17. The main objectives were to study the effect of different irrigation levels [A1=100% of crop water requirements (ETcrop), A2=80% ETC and A3=60% ETC], three rates of nano-fertilizer (lithovit) (B1=0, B2= 200 and B3=400ppm), three levels of nitrogen fertilizer (C1=60, C2=80 and C3=100 kg N fed-1) and their interactions on yield and its component, water use efficiency (WUE), fertilizer use efficiency (FUE) and quality of durum wheat plants. The experimental design was a strip-split plot with three replications. The tested agronomic traits were: plant height, No. of tillers m-2, spike length, No. of grains spike-1, 1000-grain weight, grain yield, water use efficiency (WUE), irrigation use efficiency (IWUE), fertilizer use efficiency (FUE) as well as protein and ash content, hectoliter weight and Hegberg falling number. The results indicated that the irrigation levels, nano-fertilizer concentrations and N-levels had significant effects on most yield component, water parameters, fertilizer use efficiency and quality of wheat plants in both seasons. Increasing irrigation levels from 60% to 100% increased all agronomic traits and FUE, but WUE, IWUE and falling number were decreased. The treatment of 400 ppm nano-fertilizer produced high values of all yield parameters, water relation, FUE except falling number. Increasing N-levels from 60 to 100 kg N fed-1 increased all studied traits, but FUE and falling number were deceased. The maximum grain yield (2192.4 and 2251.6), (2026.8 and 2075.7) and (1904.3 and 1964.3 kg fed-1) were produced when 100% of irrigation water, 400ppm of lithovit and 100 kg N fed-1 were applied in the two seasons, respectively. Based on the obtained results, it could be concluded that highest irrigation level of 100%, nano-fertilizer concentration of 400 ppm in combination with N-level of 100 kg fed-1 is suitable for Toshka climatic conditions to increase the grain yield and quality of wheat (Triticum durum L.).

The Effect of Various Levels of Salt Stress, on Seed Germination of Blue Panicum and the Possibility of Alleviating Damage by Lyso-phosphatidylethanolamine (LPE)
Panicumantidotale Retz (Blue Panicum) is considered as a new forage crop recently introduced to Egypt, which emphasizes the need for an assessment of its tolerance to salinity stresses. The objectives of the study were to (1) investigate the effect of various levels of salt stress on seed germination, (2) define the threshold of damage by increasing concentration of salt stress, (3) determine the possibility of enhancing seed germination by pretreatment of seeds with lisophos and (4) examine the possibility of synergism between lisophos and low salinity level as to alleviate salt to germinate at certain a concentration of lisophos. Results showed that at a certain extent, there was a synergistic effect between salt concentrations and the percentage of seed germination. Since the soil content with NaCl of 1000 or 3000 ppm led to a significant increase in the germination (61.75% and 53.95% respectively) as compared with the control (47.70%). The influence of various used concentrations (0 ppm, 5 ppm, 10 ppm, 20 ppm and 40 ppm) of the natural compound lisophos on germination percentage of the pretreating seeds revealed that the control seeds had the least germination percentage among all treatments. To check the possibility of alleviating salinity stress injury, lisophos used concentrations at 5 ppm and 20ppm, were used to protect the seed then seeds were exposed to salinity stress concentrations. Data showed that there was a significant increase in the germination percentage of Blue Panicum by the application of lisophos at 5 ppm to salt exposed seeds at 5000 ppm. On other hand data indicated that there was an adverse effect on the germination percentage by applying lisophos at 20 ppm in the presence of salinity at 3000 ppm or 5000 ppm since the highest percentage was obtained with the control. This study may add valuable information about Panicum antidotale tolerance to salinity as well as capability and potentialty of lithophosphatidyl ethanol amine (lisophosph or LPE) as growth regulators in stimulating germination of Panicum antidotale seeds and alleviating the damage of salinity to th

Eefficiency of Certain Insecticides Alone or in Mixtures Against the Tomato Leaf miner, Tuta absoluta (Meyrick) Under Field Condition, Assiut Governorate, Egypt
Tomatoes are affected by insect pests which reduce their quantity, quality and profitability. The tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) can cause 100% yield loss. Field trials were conducted to evaluated six insecticides and four of their mixtures against this pest under field conditions. The six evaluated insecticidal treatments were applied in two consequent sprays within an interval of 17 days between each, in addition to the treatment of untreated check. The lonely or individually evaluated insecticides included indoxacarb, emamectin benzoate, spinosad, imidacloprid, lambda-cyhalothrin and acetamiprid which sprayed according to the recommendations of the Egyptian Ministry of Agriculture. Meanwhile, their evaluated mixtures emamectin benzoate+ lambda-cyhalothrin, indoxacarb + abamectin, emamectin benzoate + methomyl and abamectin + thiamethoxam were applied at the rate of half recommended dose of each insecticide within the tested mixture. All the insecticides alone or in combination were significantly better than untreated check in reducing pest population. The average reduction percentages for insecticides alone against leaf miner after first spray were 68.9, 64.9, 56.2, 50.5, 47.3 and

Effect of Preharvest Application of ProTone, Methionine and Oleic acid as Alternative Materials to Ethephon for Enhancing Berry Coloration and Quality of "Flame Seedless" Table Grapes
In this experiment, ten-years-old "Flame Seedless" grape-vines at El-Nubaria region, Behira governorate, Egypt, were preharvest sprayed during 2016 and 2017 seasons with water only with surfactant (control), 400 mg/ L ethephon, 100 mg/ L ProTone (active ingredient of Abscisic acid 10%), 100 mg / L methionine, 400 mg/ L oleic acid, ProTone plus methionine, ProTone plus oleic acid and ProTone plus methionine and oleic acid, in order to investigate their influence on berry coloration, berry quality of grapes and the possibility of using these materials as alternatives to ethephon treatment. The results revealed that ethephon, ProTone, methionine and oleic acid-treated grapes increased berry anthocyanin contents, TSS and decreased berry acidity and chlorophylls. On the other hand, the formulation containing ProTone, methionine and oleic acid possessed higher anthocyanin contents and reduced berry shattering in addition to weight loss percentage as compared with ethephon and control treatments. This study recommended using the formulation containing ProTone plus methionine and oleic acid at véraison (10- 15% berry coloration) as an alternative to ethephon treatment for enhancing berr
