The research aimed at identifying risks facing agriculture from water availability and natural hazards by planning the cropping pattern under low risk, and studying the impact of both climate change and geographical area on the productivity per Feddan. The study estimate risk of cropping pattern in the first scenario was estimated to be about 6.6% under normal restrictions. In the second scenario, it was 3.04% under normal restrictions in addition to stabilize the area of rice at 750,000 feddans, with self-sufficiency of 10% and 20% of wheat and maize The total return on risk under the first and second scenarios was about 73.315 and 75.133 million pounds. The cropping pattern in the second scenario is better than the first, as it achieves a higher net return and also achieves state policies  in terms of reducing the rice area. It also increases the self-sufficiency of  wheat and maize. The effect of climate change and geographical area variation on productivity during the period (2013-2016) showed that their impact ranged from 61 to 92%. There Also was a negative impact of climate change on the productivity per Feddan. except for wheat crop the effect of either wheat has not been determined. The study recommended pulling the optimal cropping pattern, the need to increase the awareness of the seriousness of the negative effects of climate change and the development of awareness programs through the various media, and the production of new varieties afford climate change and salinity, and the use of modern technological methods Such as protected agriculture.

Germination is a way to improve agricultural productivity and easily to use by low income families, in particular with using some elicitors in germination for enhancing the nutrition value of the seeds by sprouting. For their highly metabolic activities after harvesting, radish seeds were selected for performance of this study. The effect of using abiotic elicitor (saline water, by NaCl at different concentrations) and biotic elicitor (Saccharomyces cerevisiae) on sprouting of radish seed has been investigated. After germinating radish seeds for six days using elicitors, chemical analysis and determination for phytochemicals contents have been carried out. Results showed a promising efficiency by sprouting, where an appreciable increasing in some analysis as protein, carbohydrates, some minerals and amino acids comparing to seed. Besides, germination had a positive effect to present some phyto-compounds as some flavonoids, terpenoids and phenolic compounds. Then, this study and similar ones are an important step towards the future development of value-added foods with elicited phytochemicals and can be used in the development of innovative food products with beneficial effects on human’s health.

Two experiments were carried out under low polyethylene tunnels which furnished with drip irrigation during the two successive winter seasons of 2014-2015 and 2015-2016 at Elbrollous area which represents the circumstance and conditions of coastal zone of north Nile Delta kafr Elsheikh Governorate. The objective of the investigation was to find out the effect of grafting by different cucurbita rootstocks on cucumber hybrid "ESHRAK" (Cucumis sativus, L.) on vegetative growth, flowering, yield and fruit characteristics, beside nutrient contents of cucumber plants. Results showed that grafted cucumber plants on Super Shintoza led to significant increase in vegetative growth,i.e., stem length, number of leaves, number of branches and leaf area,fruit fresh weight (g), number of fruits, total yield were greater with grafted cucumber plants on Super Shintoza followed by grafted cucumber plants on cv. Ferro. However grafting had no significant effect on potassium % of fruit on both seasons. The highest total yield was obtained by grafting cucumber plants on Super Shintoza rootstock followed by grafting on cv. Ferro rootstock by 130 % and 73 %, respectively in the first season and 160% and 147 %, in the second season respectively as compared with ungrafted cucumber plants. Accordingly, this study ensured that the use of rootstocks were more beneficial than ungrafted cucumber in both tested seasons.

Tomato (Lycopersicon esculentum Mill.) is considered the major and important globally vegetable crops especially in Egypt. Tissue culture techniques have facilitated the induction of mutant which helps in crop improvement. The mutation induction in vegetative crops through tissue culture may be the optimal method to improve these crops. Tomato explants of Idkawy Egyptian cultivar were cultured in vitro on MS medium supplemented with 0.2 mg/L BAP. The resulted plantlets were irradiated with different gamma radiation doses (50, 100, 150, 200 or 250 Gy) and the survival and mean of shoot length decreased as gamma radiation doses increased. The survival percentages of irradiated plantlets were ranged from 78.75% with 50 Gy dose to 18.75% with 250 Gy dose, while the shoot length values were decreased by a rate of 2.71 cm for dose 50 Gy and 1.2 cm for 250 Gy dose. The ten SCoT primers amplified a total of 114 amplicons with a range from 4 with SCoT-4 primer to 18 amplicons with SCoT-5  primer with an average of 11.4 amplicons per primer, The radiation specific markers were ranged from one fragment with SCoT-1 and SCoT-2 primers, SCoT- 5 two fragments with primer to five fragments with SCoT-3 and SCoT-33 primers.

Canola (Brassica juncea L.) and mustard (Sinapis alba L.) seed sprout effects on diabetic rats  have no available information and to clarify their effects, both sprouts were investigated in streptozotocin (STZ) induced diabetic and normal rats. Rats were fed on a semi-modified diet containing 10% of canola or mustard sprouted using tap or saline water for sprouting ad-libitum for 6 weeks. STZ showed increases in blood sugar, low density lipoprotein cholesterol (LDL-c), vary low density lipoprotein cholesterol (VLDL-c) and triglycerides (TG). The addition of canola and mustard with or without salinty at 10% to diabetic rats diet as semimodified diet resulted a significant decrease in blood glucose, TG and VLDL-c and data was more pronounced using mustard sprouted or saline water without changes in the HDL-c   parameter. These results showed that canola and mustard especially mustard sprouted in saline water had a hypoglycemic activity in diabetic rats and partly improved lipid metabolism in the experimental rats, with non-toxic to rats in doses given  over 6 weeks period in this study.

Two famous Citrus rootstocks sour orange (C. aurantium.) and volkamer lemon (C. volkamariana.) were tested as interstocks at the stage of transplant production to investigate their mutual effects on the scion growth characteristics, mineral content, carbohydrates, total indols and phenols from side; and rootstock growth traits. nitrogen content, carbohydrates, indols and phenols from the other side. Also the results indicated that Navel orange budded on C. volkamariana grafted on C. volkamariana achieved significantly the highest scion height, root length, leaf number. The highest content of N, P, K, Mg, Fe, Zn, Mn and total phenols in scion stem. Moreover, the mentioned treatment gained the highest significant carbohydrates in roots.

In the current research, wheat grains were used to study the effect of grain soaking and sprouting using tap water and saline water (NaCl solution) on sprout growth, proximate analysis, minerals content, anti-nutritional and antioxidant compounds of sterilized grains (soaked for 0.33h) and soaked grains for imbibition (12h) and sprouted grain for 24h old. Results revealed that the longest radical of 24h old wheat sprout was observed at 2000 ppm NaCl, and shortest was observed at 4000 ppm NaCl. Soaked wheat grains (12h) for imbibition recorded the highest moisture content (10.2 to 10.9%) while soaked for 20 min (0.33h) in calcium hypochlorite for sterilization recorded medium content (8.8 to 9.9%) and the lowest one recorded in 24h  old wheat sprouts (6.9 to 7.2%). The low moisture content the high total carbohydrate, total fats and energy and vice versa. Soaked grains for sterilization period (0.33 h) and imbibition (12h) increased zinc (Zn), manganese (Mn) and calcium (Ca) while non-sterilized only potassium (K). Tap water increased sprout magnesium (Mg), and manganese (Mn) content while saline water increased sprout magnesium (Mg), and calcium (Ca) content. Grain sprouting was effective in reducing phytic acid, oxalate and alkaloids anti-nutrient in wheat sprouts especially when using sterilized grains. Soaking non sterilized grains for imbibition (12h) in saline water contained higher total phenol, flavonoids and total antioxidant. Etiolated wheat sprouts contained lower total  flavonoids and antioxidant compared with soaked grains in saline water.

Selenium is a trace element essential in animal nutrition and exerts multiple actions related to enhance animal production, fertility, immune response and antioxidant defense system of chickens. The aim of the present study is investigating the benefit effects of selenium nanoparticles (SEN) in-ovo injection on productive performance, express stimulate antioxidant defense system and immune response of hatched chicks.  A total of 210 broiler breeder eggs ( Habbard Star-Bro) were divided into three in-ovo injection treatment groups,( 0, 5 and 10 ppm SEN) and incubated. Hatchability traits , productive performance,  biochemical profile, antioxidant status and immune response of hatched chicks were estimated. Results indicated significant increase in HDLcholesterol, T3, GSR, GSH, IGA, IGM and IGG as affected by in-ovo inoculated SEN levels. However feed conversion ratio, triglycerides and MDA significantly decreased by in-ovo treatments. No significant alternations were recorded in hatched chicks weight, feed intake, body weight, body weight gain, carcass characteristics, and serum levels of protein fractions, cholesterol, LDL- cholesterol, ALT, AST, ALP, uric acid, creatinine and glucose in in-ovo treated groups compared with the control one. It is summarized that, in-ovo inoculation of different levels of SEN can improve feed conversion ratio, lipid profile, antioxidants status and immunity of  broiler hatched chicks.

Plectranthus barbatus Andrew (Coleus forskolii) is one of the important species of the genus Plectranthus (Coleus) belonging to family Lamiaceae, with a many of traditional medicinal uses in India. C. forskolii is only known source of forskolin; a compound with a many uses in pharmaceutical industries. C. forskolii was lack in Egyptian flora. Moreover, there were no previously studies on this plant in Egypt. Therefore, the present study used tool of biotechnology to conserve the stocks of this plant by micropropagation. C. forskolii seedlings came from its native Thailand at June 2013 and were put in the greenhouse in Desert Research Center for creating an efficient micropropagation protocol. The study was carried out on the effect of growth regulators (cytokinins and auxins) on different micropropagation stages of the explants. In multiplication stage, initiated shoots were cultured on MS medium supplemented with various concentrations (0.5, 1.0, 1.5 and 2.0 mg/L) of cytokinins (6-benzylaminopurine (BA), Kinetin ( KIN) and Thidiazuron (TDZ). The mean number of axillary shoots per explant of C. forskolii reached the highest value 6.19 ±0.573 on MS medium containing 2.0mg/L TDZ. Where, the highest value of mean length was 6.44± 0.310 cm on MS medium containing 1.0 mg/L KIN. The mean number of roots / explant of C. forskolii reached the highest value and the mean length were 30.00 ± 0.577 and 11.8±0.860 cm respectively, on 1/2 MS medium containing 0.5mg/L indole-3-butyric acid(IBA). While, the highest value of shoot length was 11.8±0.860 cm on 1/2 MS medium containing  2.0mg/L naphthalene acetic acid (NAA). A percentage of 83% of rooted plantlets were successfully acclimatized after four weeks and grown normally in the greenhouse in sterile soil mixture of garden soil,  vermiculate and sand (2:1:1/v/v/v). The protocol could be cost effective and useful in germplasm conservation and delivery of tissue cultured Coleus plants.
