Response of Two Sugar Beet Cultivars to the Application level and Time of Nitrogen fertilizer
أستجابة صنفین من بنجر السکر لمستوى ووقت أضافة السماد النیتروجینى
Two field experiments were carried out at Agronomy Department Exp. Farm, Faculty of Agricultural, Assiut University, Assiut, Egypt 2010/2011 and 2011/2012 seasons to investigate the response of two sugar beet cultivars to nitrogen application level and time. A randomized complete block design (RCBD) using a split-plot arrangement with three replications was used. Two sugar beet cultivars were assigned to the main plots while, seven the nitrogen combination were randomly arranged in the sub-plots.
The obtained results showed that the N fertilizer application level and time had a significant effect on the root and top fresh weights and yields of sugar beet plants. Increasing the N applied level up to 120 kg fed.-1 decreased the sugar percentage and juice purity of roots. On the other hand, the early application of N at 30 days after planting using 90 kg N fed.-1 splitting into three doses was ranked to be the best treatment for improving the root quality and increasing the root gross and extractable sugar yields. The purity of root juice that combined with a good sugar yield quality was obtained from applying the three equal doses of N fertilizer in compared with two equal doses. It can be concluded that the N applied level at three times of plant growth stages lead to raise the yield and quality of the tops and roots of sugar beet.

أستجابه صنفین من الفول السودانی للرش الورقى ببعض المغذیات الصغرى وأضافة الکبریت تحت ظروف شرق العوینات
Two field experiments were conducted at East of El-Ewinate Agricultural Research Station, New Valley, Egypt during 2013 and 2014 seasons to investigate the response of two peanut varieties to the foliar application of some micronutrients (Fe, Zn and Mn) and sulphur addition. A randomized complete block design (RCBD) using a split- split-plot arrangement with three replications was used. Seven combinations of Fe, Zn and Mn were randomly allocated in the main plots. Two elemental sulphur levels (200 and 400 kg fed.-1) were randomly assigned in the sub-plots, as well as two peanut varieties (Giza-6 and Sohag-110) were arranged in the sub-sub-plots. The obtained results showed that, the peanut varieties varied significantly in most studied traits except the shelling percentage in both seasons. Sohag-110 variety surpassed Giza-6 in the most studied traits of peanut crop. The foliar application of micronutrient treatments had a significant influence on all studied traits of peanut crop in both growing seasons. Also, the interaction of varieties and the micronutrients foliar application showed a significant impact on some studied traits compared to the control. The yield and its attributes were significantly affected when sulphur and micronutrient treatments were applied. The highest mean values of most studied traits were obtained by applying 400 kg fed.-1 of sulphur with adding Fe +Zn + Mn treatment as a foliar spray. Moreover, the highest mean values of yield and its attributes as well as oil yield were obtained by adding 400 Kg fed.-1 of sulphur and spraying Sohag-110 variety of peanut crop with Fe + Zn + Mn treatment.

Impacts of Recurrent Selection and Synthetic Population on Forage and Seed Yields of Monocut Egyptian Clover (Trifolium alexandrinum L.)
تأثیر الانتخاب الدوری والعشیرة الترکیبیة علی المحصول العلفی والبذری فی البرسیم المصری وحید الحشة
The objectives of the current investigation were to determine the response of forage and seed yields and their components in monocut Egyptian clover to two methods of breeding, namely recurrent selection and synthetic population approach. One cycle of recurrent selection among superior accessions was imposed on a base population. Both yields were compared to the base population and a commercial cultivar (c.v. Fahl). In addition, first generation of a synthetic population created by compositing six superior accessions was compared to the commercial cultivar and their parents.
The realized gains of the recurrent selections were 18.6, 11.7, 14.6 and 24.1% for leaf/stem ratio, fresh, dry and forage protein yields, respectively, over the base population. Moreover, the realized gains were 14.4, 19.2, 13.1 and 16.9% for number of inflorescences/plant, number of seeds/inflorescence, seed yield and 1000-seed weight, respectively, over the base population.
The first generation of the synthetic population showed increases over parental means of 3.5, 3.0, 4.9 and 3.8% for leaf/stem ratio, fresh, dry, and forage protein yields, respectively. Similarly, the realized gains were 5.0, 5.3, 3.1 and 4.3% for number of inflorescences/plant, number of seeds/inflorescence, seed yield and 1000 seed weight, respectively, over to the check cultivar (c.v. Fahl).

Effect of Schinus molle and Schinus terebinthifolius Extracts on Sweet Pea Damping-off
تأثیر مستخلصات من نباتی الفلفل الرفیع والفلفل العریض على مرض موت البادرا ت
فی بسلة الزهور
The potential efficiency of leaf and stem extracts of Schinus molle and Schinus terebinthifolius against Fusarium solani in addition to the phytochemical screening of both species was studied. Extracts were prepared using different solvents (water, ethanol, methanol and acetone). Fusarium solani was isolated and identified from naturally diseased sweet pea (Lathyrus odoratus) plants. According to the pathogenicity tests, the highest pathogenic isolate was used to test the antifungal activity of each extracts with different concentrations on mycelial growth of F. solani in vitro. The effect differed according to the extract type and concentration. The potential antifungal activity of ethanol extracts appeared highly significant when used with leaves, regardless of plant species, whereas acetone was effective when used with stems. The highest reduction of F. solani growth was obtained by ethanol and aqueous extracts of S. terebinthifolius leaves, ethanol extract of S. molle leaves, acetone extract of both S. molle and S. terebinthifolius stems, respectively. Effect of extracts at 64 mg/ml on damping-off incidence of artificially infected L. odoratus under greenhouse conditions was studied as well. The highest reduction of the disease was achieved by leaf extracts of S. terebinthifolius followed by S. molle. These results were attributed to the presence of alkaloid, phenolics, flavonoids, and tannins in leaves and stems of both plant species as revealed by the phytochemical screening. Significant negative correlation was detected between in vitro inhibition percentage of F. solani and the field incidence of damping-off in L. odoratus plants. These results suggest that extracts from S. molle and S. terebenthefolius, especially ethanol leaf extracts and acetone stem extracts, are promising naturally derived antifungal agents for F. solani and other plant pathogenic fungi.

Assessment of Two Newly Introduced Parsley Varieties for Productivity and Quality as Affected by Iron and Magnesium Foliar Application under Upper Egypt Conditions
تقییم النمو ومحصول الزیت الطیار لاثنین من أصناف البقدونس المستجلبة حدیثًا تحت ظروف صعید مصر متأثرة بالرش بالحدید والماغنسیوم
A field experiment was conducted to evaluate the performance of two parsley cultivars under the conditions of Assiut, Egypt. Response of both varieties to foliar application of iron and magnesium at four concentrations (0, 100, 200 and 400 ppm) was studied. Results showed considerable differences in the productivity of both cultivars where cv. Gewone Snij3-RIALTO (RIALTO) surpassed cv. Moskrul 2-KARUSA (KARUSA) in terms of fresh and dry weight, essential oil and leaf pigment content in both seasons. Foliar application of Fe and Mg separately or combined together at different concentrations revealed significant effect on growth parameters of both cultivars. The effect became more pronounced during the second and the third cuts. Increasing the concentration of either Fe or Mg resulted in significantly better results. The best interaction was found in cv. RIALTO plants sprayed with Fe at 400 ppm combined with Mg at 200 ppm, whereas cv. KARUSA plants produced the best results when the same concentration of Mg (200 ppm) was combined with Fe at 200 ppm. It could be concluded that productivity and quality of parsley depended significantly on cultivar, cut and foliar nutrition. Cv. RIALTO showed noticeable superiority over cv. KARUSA under Assiut field conditions.

Optimal use of nutrients based on soil analysis can improve crop productivity and minimize environmental pollution. Therefore this study aimed to assess forms of both potassium and phosphorus in soils of Assiut and the relationship between both elements and some soil properties. The study area was divided into 10 transects and 54 soil profiles were selected. Soil samples from two depths (0- 30 and 30- 60 cm) at each location were collected then they were analyzed by standard methods. Available and total content of both phosphorus and potassium were measured.
The correlation matrix of soil properties shows that several physical and chemical variables were correlated with each other especially, CaCO3, OM, pH, EC and CEC. Soil salinity (EC) of 90% of soil samples were less than 2 dS/m. Soil reaction (pH) of Assiut Governorate ranged from 7.22 to 8.92 with average value of 7.98. The soil organic matter (SOM) content of Assiut governorate ranged from 0.33 to 4.09% with average value of 1.51 %. Available phosphorus was low in 63.9%, medium in 21.3% and high in 14.8% of the soil samples. Available phosphorus was low in 63.9%, medium in 21.3% and high in 14.8% of the soil samples. Available potassium was low in 16.7% soil samples and 60.2% of soil samples were medium. The remaining 23.2% of soil samples were high. Soil Nutrient Index of the study area was found in category of low phosphorus, medium potassium and high OMC.

The Strategic Distribution of Public Investments on the Commodity Sectors and its Impact on the Agriculture Sector in Egypt
إستراتیجیة توزیع الاستثمارات العامة على القطاعات السلعیة وإنعکاساتها على قطاع الزراعة فی مصر
Despite the importance of the agriculture sector in the Egyptian economy, but the attention of successive governments in this vital sector is not commensurate with its importance, where decreased year directed to the agriculture sector investment value, So the search target to answer the following questions: Are there significant differences in public investment between commodity sectors?, Is the public investment distribution in Egypt on economic sectors according to the coefficient of employment or the rate of investment?, What the amount of the target in the agriculture sector of public investment according to the most important factors specific to him? And what the extent of deviation from the actual public investment target counterpart?, Does the value of public investment in the agricultural sector affect on the amount of both domestic and foreign investment?, turns out that there are significant differences confirmed statistically in the value of public investment between commodity sectors and some of them, it turns out that, despite the fact that the agriculture sector came first as one of the sectors most efficient in terms of minimum investment required to hire one worker value but it shares in second place and the third in terms of overall communicated to him the investment value, and that, despite the fact that both agriculture and the construction sector come in the first place as the most sectors efficiency in terms of return on the British investor, however, each comes in third and last place in the public directed to two investment value, As it turns out that the desired level of public investment in Egypt exceeds the actual counterpart, with an average ratio target of public investment actual counterpart level during the study period of about 1.76%, it has been shown to increase public sector investment in the agriculture sector increased by 100% lead to increased gross domestic product for the same sector by 17%, which represents a case of diminishing return on Sahoy references to the need for the agricultural sector to receive more public investment to reach the economic efficiency gay, and it turns out that the most important determinants of value for domestic investment is the total state spending on infrastructure the agriculture sector to the age of its predecessor and return on your investment, as well as the total state spending on infrastructure agriculture sector to the age of its predecessor is the determining factor for the value of agricultural foreign investment.

Greenhouse- grown Cucumber as an Alternative to Field Production and its Economic Feasibility in Aswan Governorate, Egypt
الجدوى الاقتصادیة لإنتاج الخیار فى الصوب الزراعیة کبدیل للإنتاج الحقلى فى محافظة أسوان (مصر)
A greenhouse experiment was carried out in 2014/2015 in the Research Station at Faculty of Agriculture and Natural Resources, Aswan University to investigate pilot/experimental greenhouse model facilities to improve efficiency of integration along the value chain of cucumber crop and provide a guide for greenhouse cucumber growers in Upper Egypt. The area of the greenhouse was 4200 m2 representing the most common economic module in terms of unit size for the greenhouse vegetable industry. The cucumber cultivar ‘Barracuda F1’ was cultivated in the greenhouse and ‘Elmayadeen’ in the open field. The results revealed that the total harvest yield of the cucumber cultivar ‘Barracuda F1’ under greenhouse was 5 times the open-field yield of the cultivar ‘Elmayadeen’ in the area; as well as, the water used for irrigation was 70 % less than in open-field. The mean variable costs, average fixed costs and total costs for the greenhouse production system were higher than the open field production system. The total gross revenue and margin were 114000 L.E and 84383 L.E for the greenhouse cucumber, while the gross revenue and margin for the open-field cucumber were 19400 L.E and 15047 L.E. The mean net profit was 61830 L.E for greenhouse and 13666L.E foropen-field cucumber. The results revealed that the net profit for greenhouse cucumber growers was thirteen times higher that of their open-field counterparts. The average yield off for the greenhouse cucumber was higher by 24.74 ton (45.6-20.86=24.74) ton, while in open field the average yield off was higher by 6.84 ton (9.7-2.86=6.84). The financial indicators indicated higher convenience for greenhouse cucumber production system, highlighting a NPV equal to 223353 L.E, an IRR to 48.11%, which can be compared to the interest rate which was about 11% to prove the profitability of greenhouse cucumber project. The cucumber greenhouse system has been shown to have a higher profitability than the open-field system as shown by the private and social profits and is more efficient which compensates its extra costs.
