The present study aimed to justify the effects of restricted feeding periods during last month of pregnancy and initiation of lactation on growth rate of Maghrebi she-camel and their offsprings. Sixteen pregnant she- camels with an average body weight 512.74 kg were divided randomly into three groups. The first group (G1) was fed 100% of their daily requirements concentrates. The second group (G2) was offered 75% of their daily requirement of concentrates after delivery for one month, while the third group (G3) was fed on 75% of  their daily of concentrate requirements for two months (one month pre and another one post-partum). New born calves were divided after one month of lactation to four groups as following; calves born  G1 dams were divided randomly to two subgroups. The first one (G11) suckled their dams naturally, while the other (G12) was artificial reared on a milk mixture (50% natural camel milk and 50% cattle milk replacer). Calves born to G2 and G3 dams were artificial reared on a mixture 50% natural camel milk and 50% cattle milk replacer. Results obtained showed that she-camels of G1 gained insignificant more live body weight than that of G3 during the pre-calving period 49.09 vs. 42.05 kg, respectively. There were insignificant differences among the 3 groups in calves birth weight 30.44, 32.8 and 29.73 kg, respectively. During lactation period, she-camels of G1 produced insignificantly more daily milk in compare with the corresponding she-camels of G2 and G3 (3.78 liter vs. 3.32 and 3.4 liter/ animal), respectively. She-camel of G3 lost significantly (P˂0.05) more LBW from the beginning of the experiment to the end of the study in compare with both of G1 and G2 she-camels. Calves of one month of age and born to G1 dams indicate faster (P˂0.05) daily gain (0.326 kg / h/ day) than those to both of G2 and G3 dams. Three months old age calves of different groups, indicated nearly similar growth, regardless of their dams feed restriction and type of calves rearing (natural vs. artificial). Data obtained showed also that neither she-camels feed restriction practice nor type of calves rearing have any significant effect on either calves daily gain or dams final LBW after 3 months of treatments.

The issue of  water resources using which make the best using  stayed one of the most important issue  which Egyptian society suffer from on the two levels  individual  and national .  The research depended for a achieving his goals on the discriptive and statistical method which representative on linear programmar method and the researcher depended on the data which be published by research associations such as the central agency for the general mobilization and statistics and ministry of agriculture and  reclaimation the lands.  The research showed that the limitations of crops combination are (the agricultural land – the water resources) and the constraints which be used in linear programmar model are (crops area- feddan return net) and by the looking for the   actual crops combination we can observe that it consist of (42 crops divided into (17 winter crops – 13 summer crops- 6 nile  crops- 6 fruits) and from the research results showed that the gross water amount was (46271.5) million m3 and the water amount for the winter crops was (14870.7) million m3 and the water amount for the summer crops was (23552.6) million m3 whereas the nile crops was (1041) million m3 and the fruits was (6807.2) million m3 and which related to the crops area the results showed that the gross area was (13678254.7) feddan and the winter crops was (6613977.2) feddan whereas the summer crops was (5325536.7) feddan and the nile crops was (392740.8) and which related to the fruits was (1246000) feddan

The influences of grafting treatments (6001 and Star rootstocks in addition to, check nongrafted transplants) and some foliar spray treatments (potassium silicate at rate 4 and 5 ml/L, calcium at rate 1 and 2 ml/L and check) on growth, yield and fruit quality of watermelon cv. Aswan F1 were investigated. The experiment was conducted in Baloza Research Station, Desert Research Center, at North Sinai Governorate during the two successive growing seasons of 2016 and 2017. The results indicated that plants sprayed with potassium silicate at a rate 5 ml/L or grafted onto Star rootstock recorded the highest significant values on transplant stand (success) percentage, vegetative growth characteristics (plant length, fresh and dry weight), yield and its components (fruit weight, fruit size, rind and flesh thickness and total yield), while the lowest values were observed in check nongrafted plants. Meanwhile, grafting had reducing effect on fruit quality, where the highest values of total soluble solids and total sugars were found in the fruits of nongrafted plants. The application of 5 ml/L potassium silicate gave the best significant values of TSS and total sugars compared with check treatment during the two studied seasons.

Salinity is a major limiting factor for tomato crop growth and productivity especially in arid and semi arid lands region. Therefore this study was conducted to study the effect of applying sugar beet molasses, priming tomato seedling in saline water and Fe-EDHHA on mitigating salinity negative effects on tomato (Lycopersicon esculentum L.)  hybrid super strain B (salinity sensitive hybrid). Seedlings of tomato hybrid were transplanted on April 4th in both seasons 2014 and 2015 in pots contains washed sandy soil, and irrigated with saline water with EC of  2000, 3000 and 4000 ppm. Beet molasses and Fe – EDHHA were applied at  rates of 200 and 300 kg / fed. for beet molasses and 3 and 4 kg / fed. for Fe – EDHHA. Priming tomato seedlings in saline water treatment was applied at 5 and 6 dS/m for 24 hours.  Data showed that all plant growth aspects such as plant height, leaf area, plant fresh and dry weights were improved under beet molasses, Fe and priming tomato seedlings in saline water treatments compared to none treated plants (control). Yield parameters also followed the same trend. Among treatments, beet molasses at a rate of 200 kg / fed. recorded the highest significant effect in mitigating salinity negative effects. It could be concluded that beet molasses, priming tomato seedling in saline water and Fe – EDHHA treatments were more effective and efficient in mitigating salinity stress on tomato plants.

The present research was carried out in the AlGhab region, the village of Hialin, Hama Governorate, during 2015-2106- 2017 season. superior strains in addition to both check varieties (Idlib I-C and Hamma H-C) of peanuts were used. Ten stains of which were derived from the local variety Hama and other 13 strains were derived from the local variety Idlib, after exposing the seeds of the two varieties to three doses of gamma rays (200 - 250 - 300) Gy during  2010 and 2011  seasons. The twenty three M3 seeds were planted in the 2015 season and at the end of the season the superior M4 plants were selected for planting during next season (2016). In the 2017 season, M5 seeds were planted and at the end of the season the M5 plants were individually selected based on the following traits (early/day, yield kg/ha).   The results showed that the local cultivar Idlib was more responsive to investigated procedure than local cultivar of Hama.

Sunflower (Helianthus annuus L.) belongs to the family Asteraceae. The current study used the fluorescent amplified fragment length polymorphism (F-AFLP) technique for evaluating the genetic diversity among 14 sunflower genotypes including eight agronomical traits. Highly significant difference between genotypes was observed for all studied traits (p≤ 0.01). The results of correlation between the studied traits (p≤ 0.05) revealed that positive correlations were observed between most of the traits. Six F-AFLP combination were succeeded in the development of 178 molecular markers within a total of 1007 polymorphic bands, with 97.42% polymorphic percentage. Concerning the molecular markers associated traits, 73 were observed related to morphological and yield component traits. These results may facilitate the simultaneous selection of several economic traits and can thus improve the efficacy of selection based on F-AFLP in the sunflower breeding programs.

RT-PCR was conducted for four genes implicated for salt tolerance, oxidative and osmotic stresses in Egyptian gray mangroves within Nabq protected area in South Sinai Governorate. The results showed over-expression of the mRNA of ferritin (amFer1) gene as very high expression, followed by increase in  mRNA of superoxide dismutase (amSOD1) and ubiquitin conjugation2 (amUBC2).  At the same time gene expression of catalase (amCAT1) decreased.

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.

Egypt is working on the development of Egyptian agricultural exports and trying to create new markets as this leads to increasing national income and thus economic development, and this comes through improving the agricultural marketing system. Therefore, it can be said that marketing is an accelerated economic development accelerator and may be an obstacle to economic development if the agricultural marketing system is not improved, onion crop in Egypt is exposed recently to many of the problems of production and marketing as well as export problems in either fresh or preserved form that led to The decline in production  and the fluctuation of cultivated area and hence the high price of the consumer with the low quality that the global exports of onions ranged from a minimum of about 8.2 million tons in 2000 and a maximum of 8.6 million tons in 2016. As shown in the same table, India is ranked first in terms of the average quantity of onion exports. The average quantity of exports of this crop reached about 1.3 million tons, representing about 22% of the average total volume of global exports of onions, which is about 6.18 million tons during the same period.

To explore the antibacterial activities of Allium sativium (garlic) extract was tested against two waterborne pathogenic strains isolated from River Nile, to mitigate the increase of bacterial resistance to conventional antibiotics. The two isolates were identified as Enterobacter cloacae DSM 3264 BRB & Enterobacter cloacae MB11506_1CHB by MALDI-Tof-MS. Aqueous, methanolic and oil extraction of garlic were tested for their inhibitory activity against the selected strains using well diffusion method. Enterobacter sp. were more sensitive towards oil extract with inhibition zone 2.3 cm rather than aqueous and methanolic extractions with was 50%. Analysis of garlic essential oil by GC-MS dedicated six sulfur compounds represented 25% of total detected compounds in the oil.
