Sugar beet, N application time, chlorophyll, leaf area and sugar yield.
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 ni-trogen 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 per-centage 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 ap-plied level at three times of plant growth stages lead to raise the yield and quality of the tops and roots of sugar beet.

Peanut, micronutrient foliar application and sulphur addition
Research Station, New Valley, Egypt during 2013 and 2014 seasons to investi-gate the response of two peanut varieties to the foliar application of some micro-nutrients (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 as-signed 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 va-riety surpassed Giza-6 in the most studied traits of peanut crop. The foliar appli-cation 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 af-fected 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.
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 im-posed 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 pa-rental 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).

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. Ac-cording 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 ex-tracts 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. so-lani 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.

A field experiment was conducted to evaluate the performance of two pars-ley 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 productiv-ity 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 sepa-rately or combined together at different concentrations revealed significant effect on growth parameters of both cultivars. The effect became more pronounced dur-ing 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. RI-ALTO plants sprayed with Fe at 400 ppm combined with Mg at 200 ppm, whereas cv. KARUSA plants produced the best results when the same concentra-tion 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. KA-RUSA under Assiut field conditions.

Nutrient index, soil salinity, soil reaction, organic matter, available phosphorus, available potassium, fertility status.
Optimal use of nutrients based on soil analysis can improve crop productiv-ity 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.

الاستثمار ,الإستثمار الزراعي ,الإقتصاد المصري
يعتبر الإستثمار الزراعي الأداة الرئيسية لتحقيق أهداف التنمية الاقتصادية الزراعية، حيث يعتبر أحد العوامل المحددة لمسار النمو في الدول النامية، كما يعتبر المصدر الرئيسي لتوسيع الطاقة الإنتاجية بإدخال أساليب إنتاجية حديثة ترفع من مستوي الأداء داخل القطاع الزراعي كماً وكيفاً من خلال الدور الذي يلعبه الإستثمار في نقل التكنولوجيا ومن ثم زياده الصادرات، وتعمل إستراتيجية التنمية حالياً في مصر علي التحول إلي إقتصاديات السوق بحيث يقتصر دور الحكومة علي القيام بالخدمات الأساسية والمشروعات الإستراتيجية التي لا يستطيع القطاع الخاص القيام بها، وهذا لا يعني إطلاقاً إنسحاب الدولة أو إلغاء دورها في النشاط الاقتصادي ولكن تقليص هذا الدور مع ضرورة تحقيق الكفاءة، نظراً لأن البنية الأساسية الاقتصادية والاجتماعية التي تضطلع بها الحكومة لازمة لكى يستطيع القطاع الخاص الاستثمار في قطاع الزراعة من ثم يتمكن القطاع الزراعي من تحقيق المعدلات المثلي للنمو.

cucumber, Greenhouse, financial analysis, production system.
A greenhouse experiment was carried out in 2014/2015 in the Re-search 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 eco-nomic 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 har-vest 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 pro-duction system were higher than the open field production system. The to-tal 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 13666 L.E for open-field cucumber. The re-sults revealed that the net profit for greenhouse cucumber growers was thir-teen 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 conven-ience for greenhouse cucumber production system, highlighting a NPV equal to 223353 L.E, an IRR to 48.11%, which can be compared to the in-terest 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 pri-vate and social profits and is more efficient which compensates its extra costs.
