Hort. Dept. Fac. of Agric., Minia Univ., Minia, Egypt
High pH level in Egyptian sandy calcareous soils (soil of Sedmant Al-Gabl – Beni Suef Governorate) led to fix the soluble phosphorus to insoluble form such as tri-calcium phosphate. In this study, two grapevine cvs Early Superior and Superior were treated with phosphorien as a source of phosphate dissolving bacteria "Bacillus megatherium" at 20g/vine once, twice or thrice addition for three consecutive seasons namely 2012/2013, 2013/2014 and 2014/2015.
The study showed that, vines treated with phosphorien significantly increased the leaf area and shoot length especially in the third season. Application of phosphorien resulted in a significant effect on leaf mineral contents especially NPK as compared with untreated vines. Neither Superior nor Early Superior showed significant differences in magnesium contents for the three experimental seasons and calcium for the first and second seasons, whatever the number of applications.
Yield per vine significantly increased as a result of phosphorien treatments in both cultivars especially was for the vines received phosphorien three times. The response of berries chemical content to phosphorien application was much more remarkable than those of physical properties, except those of cluster weight. However, T.S.S and reducing sugars were significantly increased as a result of phosphorien treatment in both cultivars. An obvious decrease in total acidity was noticed due to the use of phosphorien, this increment was more remarkable for the Superior cultivar. The investigated treatment had no negative effect on the overall quality characteristics of berries.
To overcome soil Phosphorus fixation problem and to stimulate growth and fruiting of Superior and Early Superior grapevines growing under sandy calcareous soil, application of phosphorien at rate of 20 g/vine three times a yearly is highly recommended.

A field study was carried out at the Horticulture Research Farm of El-Baramon, Dakahlia, governorate,Egypt aimed to study the effects of salicylic acic (SA) and ascorbic acid (AsA) on mango trees cv Fagri kalan. Leaf area and its mineral contents as growth parameter, yield and its were evaluated. Data indicated that spraying treatments increased productivity of mango trees and enhanced their fruit quality, in the two seasons Salicylic acid and AsA, when applied alone, produced low productivity of Fagri kalan mango compared to their combination. Spraying with 2MmSA+1Mm AsA gave the best values in this respect. Moreover, spraying with this treatment gave the highest values of TSS and total sugars in the fruits content and lowest value in acidity comparing with other interactions treatments used in both seasons. Further investigation are need to study the effects of AsA and SA on natural defiance system on some biotic and abiotic stress condition and to trace the involvement of metabolic processes in resistance to many disorder in mango.

Two field experiments were conducted during the successive seasons of 2012/2013 and 2013/2014 at Sakha Agricultural Research Station to study the effect of SOME herbicides on wheat, NPK uptake, associated weeds and determine its residues in soil, leaves and grains of wheat plant. The results indicated that using the herbicides Granstar at 8.0 g/fed for control broad-leaved weeds, Traxos at 0.5 L/fed for control grassy weeds and Panther at 0.6 L/fed and (Granstar/Traxos) for control annual weeds as applied post-emergence as well as hand weeding twice, gave excellent weed control.
Hand weeding treatment, Panther and (Granstar/Traxos) obviously increased plant height, spike length, weight of grains/spike, number of grains/spike, straw yield (ton/fed) and grain yield (ardab/fed) of wheat as compared with the control treatment. All herbicidal treatments as well as hand weeding treatment increased protein, phosphorus and potassium percentages and their uptake (kg/fed) in wheat grains over control treatment.
The times for 50% loss of initial Granstar in soil were 50.79 and 48.33 days. The loss of initial concentration in the leaves were (0.29 and 0.74 ppm) in the 1st and 2nd seasons, respectively. The Granstar residue become undetected in grains of the two growing seasons after 159 days from application. At the end of experiments about 97.73 and 97.32% of initial traxos in the soil in both seasons were lost. After 90 days, only 0.22 and 0.26 ppm of Traxos were reached to the grains. At the end of experiment (145 days), there were no residues in the grains of the two growing seasons. The times for 50% loss of initial Panther in soil were 56.78 and 53.67 days and the loss of initial concentrations reached 97.32 and 98.84%. At the end of the experiment (152 days) there were no Panther residues in wheat grains in the two growing seasons.
These results indicated that under heavy infestation with annual weed, it is possible to apply herbicides i.e. Panther and (Granstar/Traxos) treatments for annual weeds control, Granstar for broad-leaved weeds control and Traxos for grassy weeds control. These findings revealed obviously that such weed control measure can minimize weed/wheat competition and consequently gave the highest reduction in weeds and increase wheat yield, without any effect on wheat plants or on soil.

Two field experiments were conducted at the Agricultural Experimental Station, Faculty of Agriculture, Cairo University, Giza, Egypt during 2013/2014 and 2014/2015 seasons to study the agro-economic effect of three nitrogen fertilization rates (60, 80 and 100 kg N/fed), three cropping systems (sugar beet sole, sugar beet + canola and sugar beet + onion) and four multi-germ sugar beet varieties (Farida, Carola, Gloria and Demapoly). The experimental design was a split- split plot in randomized complete block arrangement with three replications. Results revealed that increased N rates, from 60 to 100 kg fed-1 and Growing sugar beet as a sole crop significantly increased root weight, root yield and sugar yield in both seasons. Sugar beet variety Carola was superior in root weight, root yield and sugar yield followed by the variety Farida in both seasons. The main effects of nitrogen, cropping systems and varieties had no significant effect on root quality traits in terms of total soluble solids%, sucrose%, purity% and extractable sucrose% during the two seasons. The highest significant values of mean root weight (1.019 and 1.109 kg), root number (28.69 and 28.21 thousand plants/fed), root yield (29.35 and 31.47 ton/fed) and sugar yield (3.72 and 3.75 ton/fed) resulted from fertilized sugar beet sole plants with 100 kg N/feddan in the 1st and 2nd seasons, respectively. Irrespective of cropping systems, fertilized sugar beet varieties Farida and Carola plants with 100 kg N/ feddan gave the highest mean values of root weight, root yield and sugar yield during the two seasons. The interaction of cropping systems x varieties had a significant effect on mean root weight, root number, root yield and sugar yield during the two seasons. Among the tested varieties, sole planting of Carola had maximum beet root weight (0.953 and 1.043 kg), beet root yield (28.65 and 31.07 ton/fed) and sugar yield (3.69 and 3.74 ton/fed.) in the 1st and 2nd seasons, respectively, followed by Farida when planted as a sole crop. The highest and significant root and sugar yields were obtained from the sugar beet variety Carola when planted as a sole crop and fertilized with 100 kg N/feddan during the two seasons. It was observed that irrespective of sugar beet varieties and cropping systems, the highest cost of production and gross revenue were recorded when plants received 100 kg N/feddan. The cost of sugar beet (sole) production was LE. 5350 fed-1 against the production costs of LE. 5650 and 6950 fed-1 when sugar beet was intercropped with canola and onion, respectively. The highest gross revenue (19002 and 17650 LE/fed) resulted from intercropping sugar beet varieties Carola and Gloria, respectively with onion under 100 kg N/feddan. The maximum net returns was obtained under combination of sugar beet variety Carola + onion (12052 LE/ fed), followed by sugar beet variety Gloria + onion (10700 LE/fed) when plants fertilized with 100 kg N/feddan. The maximum cost benefit ratios of 1.73 and 1.54 were obtained with nitrogen rate of 100 kg/feddan under combination of sugar beet variety Carola + onion and sugar beet variety Gloria + onion, respectively. The results showed that for obtaining higher net returns from the unit area, preference may be given to intercrop sugar beet variety Carola with onion and fertilized plants with 100 kg N feddan-1.

Two herbaceous species belonging to genus Solanum namely, Solanum melongena L. and Solanum lycopersicum L. were subjected to study the incidence of the secondary growth and consequently the formation of protective tissues in their roots. The main results were as follows :
1- At an early stage of growth, the xylem tissue at the base of the root accomplished a proportion of its final amount that was decidedly bigger than that needed for the shoot system already achieved by the plant.
2- In contrast to the eggplant, no development of any periderm-like structure at the periphery of the root of tomato was detected. In the successive ages, storage depletion of food stuff in root parenchyma of the eggplant was not found in the tomato root.
3- The whole vascular cylinder was dissected into differently sized sectors by rays of varied width ranging in cross section from 2 to 6 cells. This histological characteristic was not present in the root of eggplant.
4- The root xylem in the tomato root unlike that in the eggplant looked heterogeneously perforated.

Field experiment was carried out at the Experimental Farm of Rice Research and TrainingCenter,(RRTC), Sakha, Kafr EL-Sheikh, Egypt during 2010 and 2011 summer seasons. In order to estimate general combining ability (GCA) and specific combining ability (SCA) effects of the parents and their F1 for some agronomic and yield and its component traits. This study involving ten rice genotypes, i.e. three commercial varieties (Giza178, Sakha103 and Sakha106), one promising line Gz 9057-6-1-3-2 (Giza179) and six Egypt ∕ America bold grains genotypes (SKC 23819-189-1-1-1-3-1-2-4-2, SKC 23819-192-2-1-2-2-4-2-1-2, SKC 23819-192-2-1-2-3-1-1-1-2, SKC 23819-192-2-1-2-4-5-3-2-1, SKC 23819-192-2-2-1-1-2-1-2-2 and SKC 23819-192-2-2-1-1-2-2-1-2. The parental genotypes have a wide range of variations for all studied traits, origin, pedigree and group type. Ten parental genotypes in this study were sown in three sowing dates. A line x tester cross was conducted among the ten parents (four lines and six testers) in (2010) to produce (24) crosses. The parental genotypes and their 24 crosses were studied for eight traits i.e. No of days to heading (day), plant height (cm), number of tillers plant-1, flag leaf area (cm2), grain yield plant-1 (g), number of panicles plant-1, 1000-grain weight (g), and number of filled grains panicle-1 the mean square of parents, crosses and parents vs. crosses revealed highly significant variations for all traits under investigation. GCA were found to be highly significant for all studied traits, except grain yield plant-1 and 1000-grain weight for Sakha 103 and grain yield plant-1 for line (Gz 9057-6-1-3-2) which was found to be not significant while testers, namely SKC 23819-189-1-1-1-3-1-2-4-2, SKC 23819-192-2-1-2-3-1-1-1-2 and SKC 23819-192-2-2-1-1-2-1-2-2 were also not significant for grain yield plant-1. Sakha 103 and Sakha 106 were good combiners for early maturing. Regarding to number of tillers plant-1, flag leaf area (cm2), number of panicle plant-1 and number of filled grains panicle-1, the parental variety, Gz 9057-6-1-3-2 exhibited highly significant positive GCA effects for these traits. The rice variety Sakha 106 was found to be highly significant positive GCA effects for 1000-grain weight and grain yield plant-1. While, SKC 23819-192-2-2-1-1-2-1-2-2 proved to be excellent combiner for 1000-grain weight, while SKC 23819-192-2-2-1-1-2-2-1-2 was the best combiner also for the grain yield plant-1 this traits would be of practical interest in breeding program towards developing high yielding genotypes. Three out of the twenty four rice hybrid combinations showed highly significant positive SCA effects for grain yield plant-1, 1000-grain weight and number of filled grains panicle-1, this combinations, were Sakha 103 x SKC 23819-192-2-1-2-2-4-2-1-2, Giza 178 x SKC 23819-189-1-1-1-3-1-2-4-2 and Giza 179 x SKC 23819-192-2-1-2-3-1-1-1-2.

The present study was conducted to evaluate the ecological characteristics and the bioactive metabolic products of C. procera. Also, the crude methanol extract of the aerial parts of calotropis was examined for antioxidant and antimicrobial potentialilties. The scrubland dominated by C. procera represented an advanced stage of desert vegetation and comprised 33 species related to 14 families. Tamarix nilotica, Alhagi graecorum, Launea mucronata, Trichodesma africanum and Hyoscyamus muticus were the common associates. The major life-forms were therophytes, geophytes and chamaephytes. The assemblage of this community belongs to eleven floristics categories with predominance of Sahara-Sindian, Sahara-Arabian and Sudano-Zambezian. The flavonoids and polyphenols contents of the aerial parts of C. procera were 0.185 and 0.37 g/100g, respectively. Thirteen fatty acids were detected among them undecanoic, palmitic, lauric, myristic and linoleic acids. The Calotropis methanolic extract exhibited free radical scavenging activity with IC50 value of 0.35 mg ml-1. It is showed antimicrobial spectrum only against Bacillus subtilis.

The experiment was conducted during the two successive seasons of 2013 and 2014 at the Agriculture Research Station, in El- Arish, North Sinai Governorate, Egypt. Tomato "GS12" hybrid was used in the experiment to study the effect of three water irrigation levels ,.i.e. 100 %, 75 % and 50 % from water requirements of tomato plants under foliar spray with two materials, i.e Dodouxil Benzene Sulphonate "DBS" and Potassium silicate "PS" at two rates 2 and 6 cm/liter on the growth, fruit yield and its quality as well as some water irrigation relationship. Split plot design was used in the experiment. The results showed that, irrigation at the level 100% from tomato requirements with foliar spray by any one of the materials used, i.e. (DBS) or (PS) at the concentration of 6 cm/liter then the concentration of 2 cm/liter recorded the high values of growth parameters, i.e. dry weight of tomato plant organs (roots, leaves and stem). The superior total yield was obtained from the same treatment. The same treatment hassend also, physical and chemical fruit quality. While irrigation tomato plants with 75% from its requirement led to reduction in fruit yield by 25% but in the same time saved 33.6% from water irrigation, moreover irrigation tomato plants with 50% levels saved about 43% from water irrigation and induced 50%reduction from tomato yield. Foliar spray with potassium silicate or Dodouxil Benzene Sulphonate showed significant values in tomato growth, fruit yield and its quality and increased the water use efficiency of tomato plants grown under the condition of North Sinai.

Two field experiments were conducted at the private Farm in Mansoura, Dakahlia Governorate, Egypt, during 2013/2014 and 2014/2015 seasons to improve some wheat cultivars productivity under organic, mineral and foliar fertilization. The experiments were carried out in a strip-split plot design with three replications. The vertical plots were assigned to organic manure (compost) and mineral nitrogen combination treatments. The Horizontal plots were devoted to foliar fertilization treatments (commercial foliar fertilizers). While, the sub – plots were allocated to wheat cultivars (Sakha 93, Giza 168 and Gemmiza 10).
The obtained results showed that application of 100 % (214 kg N/ha) as mineral nitrogen alone increased all growth characters, yield and yield components as well as crude protein percentages in grains as compared with other compost and mineral nitrogen combination treatments. However, application of 25 % compost (53.5 kg N/ha) + 75 % mineral nitrogen (160.5 kg N/ha) came in the second rank in both seasons.
Spraying wheat plants with Biohealth which considered as biostimulants foliar fertilizer produced the highest values of wheat growth, yields and its components and quality character and followed by spraying with Stimufol as macro and micro nutrients foliar fertilizer in both seasons.
Gemmiza 10 cultivar surpassed other studied cultivars (Giza 168 and Sakha 93) and recorded the highest values of most studied characters in both seasons. Giza 168 cultivar registered the longest spikes and the highest values of protein percentage in grains. Whereas, Sakha 93 cultivar recorded the highest values of 1000 – grain weight at the same time the lowest values of other studied characters.
It could be recommended that fertilizing Gemmiza 10 cultivar with 25 % compost (53.5 kg N/ha) + 75 % mineral nitrogen (160.5 kg N/ha) and foliar spraying with commercial foliar fertilizer Biohealth to enhance wheat productivity and also to reduce sources of environmental pollution and maintain human health.
