استجابة بعض أصناف الشعیر لمواعید الزراعة المتأخرة ومعدلات السماد النیتروجینی
تحت ظروف الوادی الجدید
This investigation was carried out at El-Dakhla Oasis in the New Valley Governorate, Egypt, during the two growing seasons of 2013/2014 and 2014/2015 to study the response of some barley cultivars to late sowing date and nitrogen fertilizer rates under the New Valley condition. Three experiments were conducted separately for each sowing date (1st Dec., 20th Dec. and 10th Jan. i.e. S1, S2 and S3) in both seasons. The randomized complete block design using split plot with three replications was employed, where the nitrogen fertilizer rates (50, 70 and 90 kg N/fed. i.e. N1, N2 and N3) were assigned in the main plots, while the cultivars (Giza 123, Giza 129 and Giza 130 i.e. Cv. 1, Cv. 2 and Cv. 3) were allocated in the sub-plots. The plot area was 10.5 m2 including 3x3.5 m (1/400 fed). The results could be summarized as the following: - Sowing date at 1st Dec. recorded the highest mean values for the plant height and spike length in the 1st season, and 1000 grain weight in the both seasons. Moreover, the tallest plants and the greatest number of spikes/m2 in the 2nd season and the maximum grain yield/fed. in the both seasons were recorded by sowing date at 20th Dec. - Number of spikes/m2, 1000 grain weight and grain yield/fed. increased with increasing N fertilizer rates up to 70 kg N/fed., as well as the tallest plants was obtained by 90 kg N/fed. rate in the both seasons. - Giza 123 cultivar surpassed the Giza 129 and Giza 130 cultivars and gained the highest mean values for 1000 grain weight and grain yield/fed. in the both seasons and number of spikes/m2 and plant height in the 1st and 2nd seasons, respectively, while Giza 129 cultivar gave the tallest plants and the greatest number of spikes/m2 in the 1st and 2nd seasons, respectively. - The S3xN1 (10th Jan. x 50 kg N/fed.) interaction treatments gave the minimum values for the plant height in the both seasons and number of spikes/m2 in the 1st season, as well as S3xN3 (10th Jan. x 90 kg N/fed.) interaction treatments gave the minimum values for 1000 grain weight and grain yield/fed. in the both seasons. However, the maximum mean values for 1000 grain weight and grain yield/fed. were obtained by S2xCv.1 (20th Dec. x Giza 123 cultivar) interaction treatment and N2xCv.1 (70 kg N/fed. x Giza 123 cultivar) interaction treatments in the both seasons. - The highest mean values for 1000 grain weight and grain yield/fed. in the both seasons and number of spikes/m2 in the 2nd season were achieved by S2xN3xCv.1 (20th Dec. x 90 kg N/fed. x Giza 123 cultivar) interaction treatments.

دراسة تأثیر معدلات مختلفة من التسمید الفوسفوری والکثافات النباتیة على إنتاجیة وربحیة الفول السودانی فى الأرض الرملیة
Two field experiments were carried out at Ismailia Agricultural Experiments and Research Station, A.R.C., El- Ismailia Governorate, Egypt, during growing seasons 2015 and 2016, respectively. In both seasons, the experiment was conducted using the split plot design in randomized complete block design with three replicates to study the effect of P fertilizer and plant density on pods and oil yields, as well as, net return. Three phosphorus (P) fertilizer rates (30, 45 and 60 kg P2O5 per fed) and three peanut plant densities (70, 105 and 140 thousand plants per fed) were tested. A split plot design replicated thrice was used. The results showed that increasing rate of P fertilizer from 30 up to 60 kg P2O5 per feddan increased significantly all the studied peanut traits except seed oil content. Decreasing peanut plant density from 140 to 70 thousand plants per feddan increased significantly numbers and weights of pods and seeds per plant, shelling and seed oil content mean, while the reverse was true for plant height in the two successive seasons. Peanut plant density of 105 thousand plants per feddan achieved the highest pods and oil yields per feddan compared with the other plant densities. Interaction between 60 kg P2O5 per feddan and 105 thousand plants per feddan increased significantly the most studied traits of peanut. Application of 60 kg P2O5/fed combined with 105 thousand plants per feddan achieved high pods, oil yields and net return.

طرق مکافحة الحشائش المحسنة فى الذرة الشامیة بإستخدام المبیدات المنفردة وتولیفاتها بالمعدلات المخفضة مع مادة مضافة الزیت المعدنى
A field experiment was carried out in Mallawy Agricultural Research Station, Agricultural Research Center, El-Minia Governorate, during 2015 and 2016 seasons to evaluate the efficacy of certain single herbicides at full rate and their mixtures at reduced rate (50 % of full rate) with mineral oil on weed control and maize productivity. Each experiment comprised of fourteen treatments as follow: the first five treatments were pendimethalin, s-metolachlor, acetochlor, nicosulfuron and dicamba+topramizonused as single herbicidesat full rate 682.5, 672, 840, 24 and 63 g a.i./fed., respectively, the next six treatments were the sequential application of the same previous herbicides at half of the rate plus mineral oil at 1 % v/v and the last three treatments were (foramsulfuron sodium 3.35 % + iodosulfuron–methyl sodium 0.11 + thiencarbazone–methyll1.07) used at full rate 22.65 g a.i./fed., hoeing twice and untreated treatment as control. Randomized Complete Block Design (RCBD) with four replications was used. The major weeds were Euphorbia geniculata, Ortega, Xanthium strumarium L., Corchorus olitorius L. and Ipomoea eriocarpa L. as broad-leaved weeds and Echinochloa colonum L. and Brachiaria reptans L. as grasses weeds.
The findings of this study showed that the sequential application of two herbicides with different site of action (pendimethalin or s-metolachlor or acetochlor combination with nicosulfuron or dicamba+topramizon) at reduced rate plus mineral oil at 1 % v/v gave better result in controlling broad-leaved and total weeds than applying the same previous herbicides alone at full rate, while, pendimethalin and s-metolachlor alone at full rate were the best in controlling grasses weeds.
The best total weed control efficiency (91.95 and 91.5 %) was achieved under treatment hoeing twice which was equal statistically with foramsulfuron sodium + iodosulfuron – methyl sodium + thiencarbazone – methyl (91.48 and 90.05 %) and with acetochlor mixture with nicosulfuron at reduced rate plus mineral oil (87.19 and 85.37 %) controlling effect as compared with untreated treatment at first survey in both seasons, respectively. Moreover, those treatments also gave the significantly higher grain yield (28.14, 27.20 and 24.98 ardab/fed.) and (26.90, 25.44 and 23.36 ardab/fed. in the both seasons, respectively), as well as ear grains weight and 100-grain weight as compared with untreated treatment.

تأثیر الجبس وطینة المرشحات والتسمید الغیر العضوى على الخصائص الکیمیائیة وجودة العصیر لثلاثة أصناف من قصب السکر
A field experiment was conducted at Mallawi Agriculture Research Station Farm – El-Minia Governorate, Egypt in two successive seasons of 2012/2013 and 2013/2014 (plant crops) to find out the influence of gypsum, filter mud cake with inorganic fertilization on chemical composition and juice quality of three sugarcane varieties. The obtained results could be summarized as follow:
Gypsum rates had insignificant effect on leaves consists of P and K and significantly on the percentages of N, S and Ca of sugarcane leaves in the both seasons. Each increment in gypsum rate was associated with a significant increase in juice quality (brix% and sucrose%) in the two seasons. Juice purity% and reducing sugars% significantly affected by gypsum rates only in the first season, but the same traits showed insignificant response to gypsum rates in the second growing season.
As for, filter mud cake with inorganic fertilization, the data cleared that fertilization had a significant effects on the traits of N, P, K, S and Ca leaves consist, juice quality traits (brix, sucrose and reducing sugars percentages) in the first and the second growing seasons.Juice purity percentage significantly affected only in the 1st season.
Also, varieties differed significantly in respect to the traits of N, P and K leaves consists and brix% in the first and the second growing seasons, but had insignificant effect in respect of S and Ca leaves concentrations, purity% and reducing sugars% not only in the first season but also in the second one as well as it had significant effect on sucrose% in the second growing season.
The second order interaction showed insignificant effects on N, P, S and Ca leaf concentrations, significant effect on brix and sucrose percentages in the first and the second growing seasons, while it showed significant effect in K concentration in the second season only, however it had a significant effect on purity and reducing sugars percentages only in the first growing season.

Effect of Spatial Distribution on Competition, Yield and Economics of Spring-Planted Sugarcane Intercropped With Some Oil Crops
تأثیر التوزیع الفراغی على التنافس و محصول و ربحیة قصب السکر الربیعی المحمل ببعض المحاصیل الزیتیة
The effect of two sugarcane row arrangements and intercropping systems with three densities of soybean and/or sunflower on yield and quality of sugarcane as well as the companion crops were investigated in two successive seasons. The study conducted at Mallawi Research Station, Sugar crops Institute, Giza, Egypt during 2013/2014 and 2014/2015. Results showed that, spatial distributions had no significant effects on the most of studied traits. Furthermore; the higher the dense of intercrop the lower the number of millable canes. Sole cane and cane intercropped with 15 and/or 30% soybean showed significant superiority over the other systems in terms of millable stalk weight and cane and sugar yields (ton fed-1).
The low dense systems of soybean (15 %) gave the greatest plant yield (kg) and the lowest seed yield (ton fed-1). Moreover; sole systems of soybean and sunflower presented the highest seed and oil yields (ton fed-1). Maximum land equivalent ratios (LERs) were showed in case of sugarcane intercropped 30 % soybean. In addition; data revealed that sunflower showed more competitive than sugarcane when they grew in associations.

دراسة الترکیب الکیمیائی والمرکبات الفعالة لاوراق نبات البردقوش Origanum majorana واستخدامها کمادة حافظة للأنظمة الغذائیة
The chemical composition and mineral elements of the leaves of the origanum majorana plant were estimated as the percentage of moisture content, protein, fat, ash and carbohydrides (5.7,6.6,8.4,18.7 and 60.6)%, whereas the concentrations of mineral elements of sodium, potassium, cobalt, iron, and barium were (0.49, 0,039, 5.1, 0.6 and 0.01) ppm respectively. The functional groups were identified through qualitative data on aqueous and alcohol extracts, it has been observed to contain (tannins, phenols, flavonoids, saponine, carbohydrates and alkaloids). Physical and chemical tests were studied, such as combustion and solubility, as they were partially dissolved in polar solvents and completely in non – polar solvents. The effect of herb powder leaves as a preservative of beef meat was studied with (0.5 and 1) % concentration of refrigeration at 5°C for (0, 7, 10) days. The changes in meat cuttings were monitored by estimating the number of peroxide. The results showed a decrease its value in the samples treated with herb powder compared to the fresh sample during the storage period, and the effect of logarithm was studied in the preparation of total bacteria and colon bacteria often the meat in the same period of storage and previous concentration. The results showed that the herb has a role in reducing the number of microoraganisms in minced meat models, as well as having an antioxidant effect by prolonging the life of the meat

المغذیات والمرکبات الکیمیائیه الطبیعیه فی ثمار الکاکا والحرنکش
The aim of this study was to determine the proximate chemical composition, minerals content, some vitamins, sugars composition, flavonoids content as well as phenols content of whole persimmon and husk tomato fruits. The results indicated that, husk tomato has higher amounts of crude protein, crude fat, crude fiber and ash compared with persimmon fruits. Iron (Fe) was the most predominant of micro-elements found in persimmon and husk tomato. Persimmon fruits contained much more Vit. K content compared with husk tomato fruits. Glucose, arabinose, xylose, glactose and fructose were the predominant sugars of both of persimmon and husk tomato fruits. The major flavonoids of persimmon fruits were narengin, luteolin, hesperidin, quercetrin and rosmarinic acid, while it were rosmarinic acid, luteolin, rutin, querectin and narengin in husk tomato fruits.
Regarding to phenolic compounds, pyrogallol was the major phenolics in both of persimmon and husk tomato followed by catechen in persimmon and benzoic acid in husk tomato.
The aim of this study was to determine the proximate chemical composition, minerals content, some vitamins, sugars composition, flavonoids content as well as phenols content of whole persimmon and husk tomato fruits. The results indicated that, husk tomato has higher amounts of crude protein, crude fat, crude fiber and ash compared with persimmon fruits.

Effect of Magnesium Fertilization and Leaf/Bunch Ratio on Growth and Fruiting of Sewy Date Palm
تأثیر التسمید بالماغنسیوم ونسبة الأوراق للسوباطة علی نمو وإثمار نخیل البلح السیوی
This study was conducted during the two successive seasons of 2013 and 2014 in a private orchard, at El-Kharga Oasis, New Valley Governorate, Egypt to investigate the effect of magnesium fertilization and leaf/bunch ratio on growth and fruiting of Sewy date palm.
The experiment was set up in a randomized complete block design in split plot arranged. The pruning treatments were imposed in main plots while the magnesium fertilization rates were put in the sub-plots. Both pruning and fertilization treatments include three levels per each.
The number of new leaf/palm, leaf area and leaf nutrient composition substantially increased with increasing leaf/bunch ratio from 6 to 10:1 leaf/bunch. Also, such growth traits materially increased with increasing magnesium levels from 500 to 1000 g/palm. All combinations of (MgSO4) at 750 to 1000 g with 8 or 10 leaf/bunch induce a considerable increase in growth traits and nutrient content in the leaves of palms compared to using 500 g N/palm and leaving 6 leaf/bunch. Fertilizing by 750 & 1000 g/palm along with pruning to leave 8 or 10 leaf/bunch was followed by yield and fruit quality of Sewy date palm compared to using 500 g MgSO4/palm and accompanied with leaving 6 leaf/bunch. Fertilizing the palm with 750 or 1000 g MgSO4 improving combined with 8 or 10 leaf/bunch ratio had no major effects.
It could be concluded that leaving 8 active leaves per each retentive bunch combined with fertilizing with 750 g MgSO4/palm gave the best results with regard to yield and fruit quality of Sewy date palm.

Effect of Thinning Practices on Fruiting of Ruby Seedless Grapevine
تأثیر طرز الخف علی إثمار العنب الروبی عدیم البذور
This study was carried out during the two successive seasons of 2015 and 2016 at the Experimental Orchard Faculty of Agriculture, Assiut University, Assiut, Egypt, to investigate the effect of cluster or berry thinning on fruiting of Ruby Seedless grapevines. Thinning treatments were performed after berry set. The experiment was arranged in randomized set up as complete block with eight treatments and three replicates one vine per each.
- Fruit thinning by removing either 20 or 30% of cluster number/vine, as well as removing 30% of cluster shoulders considerably decreased the yield. Yield was unaffected carrying out by other thinning treatments compared to unthinned ones (control).
- Removing 20 or 30% of cluster number was responsive for increasing the cluster weight. Contrarly removed 30% of cluster shoulders materially deceased cluster weight, whereas cluster weight was unaffected by other thinning treatment compared to control.
- The best cluster compactness coefficient and form was obtained due berry thinning as removing 15% of its shoulders combined by 15% of cluster apical removal.
- All berry thinning improved the grapes quality in terms of increasing berry weight, berry coloration, total soluble solid and sugar contents and decreasing titratable acidity compared to control.
From this study, it is clear that to get the high yield with good clusters and berry traits it is preferable for carrying out berry thinning by removing 15% of cluster shoulders along with cutting back 15% from the apical cluster or cutting back about 30% of the apical portion of the cluster.

Effect of some Pre- and Postharvest Treatments on the Ability of “Balady” Orange Fruits to Storage
تأثیر معاملات ما قبل وبعد الحصاد على قابلیة ثمار البرتقال البلدی للتخزین
The experiment was conducted during two successive seasons (2015 and 2016) on Balady orange trees (Citrus sinensis) which divided in two groups. The first group was sprayed with potassium sulphate (48%) in the orchard at three times sequential (March, June and August) and the second group was sprayed with water (control). Orange fruits of both treatments were collected in maturity stage and dipped in salicylic acid (SA) at 4mM/l in laboratory. The purpose of this investigation is studying the effect of SA and K on orange fruits quality during storage at room temperature (13+2 C°). Some physical and chemical properties of fruits were estimated every 10 days till 50 days (the end of storage) such as weight loss %, juice content%, acidity%, total soluble solids% (TSS), TSS/ acid ratio and ascorbic acid during both seasons. The results illustrated that, SA had a positive effect on fruit quality of the fruits treated with SA single or combined with potassium sulphate

The effect of Salicylic acid (SA) on three Cavendish banana cultivars (i.e. Zeef, imported and local Grand Naine) subjected to in vitro salt stress was evaluated. Five concentrations of NaCl (0,30,60,120 and 200 mM) were tested, among which the optimum concentration for screening was determined at 120 mM. Different concentrations of SA (0, 0.5 and 1 mM) were assessed for several vegetative and physiological traits of the three cultivars cultured upon medium containing 120 mMNaCl. Analysis of variance showed highly significant differences among cultivars, SA concentrations and salinity levels, as well as their interactions in most of the studied traits. NaCl treatment caused severe loss in vegetative and physiological traits in all tested cultivars and activated several protein bands compared with non-saline conditions. Moreover, addition of SA exhibited a beneficial effect in reducingdamage caused by salinity in several traits i.e. survival percentage, plantlet length, fresh weight, total chlorophyll, carotenoids and proline content and Potassiumuptake. In addition, SA at 0.5 mM was more effective in enhancement salinity tolerance, while high concentration inhibited most of protein bands enhanced under salinity. The results showed that among the evaluated cultivars, both Grand Naine cultivars were more tolerantthanZeef cultivar. The information

Partial Replacement of Nitrogen Fertilization by Humic Acid and Seaweed Extracts in Balady Mandarin Orchards
الاستبدال الجزئی للتسمید النیتروجینی بحمض الهیومیک ومستخلص الطحالب البحریة فی بساتین الیوسفی البلدی
This study was carried out in the experimental orchard, Faculty of Agriculture, Assiut University, Egypt, to investigate the possibility of replacing nitrogen fertilization of Balady mandarin orchards by humic acid or seaweed extract during 2014, 2015 and 2016 seasons. The experiment was arranged in a randomized complete block design with three replications per treatment, one tree each. Mineral nitrogen fertilization was splitted into three equal batches and added in March, May and August, while liquid nitrogen as organic form was added once in March. Seaweed extract spraying and humic acid as soil dressing were applied three times on mid of March, June and August. The obtained results could be summarized as follow: Using recommended nitrogen dose (RND) via liquid organic-N, as well as a combination of inorganic or organic plus humic acid or seaweed significantly increased the growth traits as well as N, P, K and total chlorophyll of leaves compared to the use of RND via mineral-N (check treatment). The maximum values of these traits were recorded on trees that fertilized with the triple form (33% mineral and 33 g humic acid plus 33% seaweed). No significant differences due to fertilize via triple form using either organic or mineral form, as well as via double form using either humic acid or seaweed extract. Fertilization via either double or triple forms could achieve a beneficial improvement to the nutrient status and C/N ratio of trees since it increased the yield/tree compared to the use of RND via mineral-N only. Using double or triple forms improved the fruit quality in terms of increasing fruit weight, pulp percentage, total soluble solids, sugar and vitamin C contents and decreasing the total acidity compared to the use of RND via mineral-N source only. The best fruit quality was recorded due to triple forms. It is evident from the foregoing results that replacing 25 to 66% of nitrogen fertilization by humic acid or/and seaweed extract improved the tree nutrient status, yield and fruit quality. In addition, it minimized the production costs and environmental pollution which could be occurred by excess of chemical fertilizers. Theremore, the growers are able to produce organic farming products.

This investigation aims to evaluate the groundwater quality of El-Dakhla oasis, New Valley governorate, Egypt and assess its suitability for irrigation. About 144 groundwater samples were collected from wells distributed in eleven transects that represent the study area. The obtained results indicated that 63 samples were under the C1S1 indicating category low sodium and low salinity hazards. Meanwhile, 72 samples in the C2S1 category showing low sodium and medium salinity hazards and 9 samples exhibited a C3S1 type resulting in low sodium and high salinity hazards. According to Wilcox diagram, 93.75% of the water samples had an excellent quality for irrigation and 4.86% of them were considered as a permissible class. The results also revealed that 49.31% of these samples gave positive chloro-alkaline index (CAI) values. However, the remaining samples (50.69%) showed negative CAI. With respect of the corrosivity ratio(CR), 140 groundwater samples (97.22%) were safe to transport in mineral pipes whereas only 4 samples (2.78%) were corrosive in nature and need non-corrosive pipe to transport and lift these groundwaters.

An Economic Study of the Effects of Agricultural Practices on the Losses of Wheat Crop in the Governorate of Sohag
دراسة اقتصادیة لأثر الممارسات الزراعیة على الفاقد لمحصول القمح فی محافظة سوهاج
Lack of sufficient attention to the problem of loss by the Egyptian agricultural policy to the lack of reliable objective estimates of it at various stages, The official statistics do not provide accurate and detailed data. The data on losses in the various operations are very necessary for the development of sound policies for the maintenance of agricultural production, The problem of the study is the existence of a large loss of the wheat crop, and the failure to implement clear and specific programs in an appropriate manner to reduce the loss of it, with inefficiency in the performance of agricultural operations, The most important factors were the effect on the loss of cultivation of this crop in Sohag governorate, which is the quantity of production and the delay of the planting time. When the production increases and the farms delay planting wheat in November, the loss of wheat yield is about 4.98 and 6.23 kg / feddan. The most important factors affecting the loss of harvesting wheat crop are increasing the amount of production as the increase in production leads to increase losses about 6.37 kg / feddan, While the appropriate time during the month of May leads to reduce the loss of wheat harvest about 13.67 kg / feddan, As for the two factors affecting the loss of the wheat yield in Sohag governorate, what is the quantity of production and the date of harvest, as the increase in production leads to increase the losses about 4.43 kg / fed, while the farmer committed to the appropriate harvest times, which lead to reduction of feddan losses of wheat yield of about 14.56 kg /feddan. As for the factors affecting the loss of drying of the wheat crop, the quantity of production and harvest in May, as the higher the production increased the loss of about 3.65 kg / fed, and as the farmer committed to the time of harvest helped reduce the loss of the wheat crop about 18.64 kg /fedan, With regard to the factors affecting the total loss of the wheat crop are the increase in production and the length of the drying period if, when using the previous inputs, the total loss of the wheat crop is about 20.18 and 23.45 kg/ feddan, respectively.
It is recommended to study the stages of harvesting, drying, storage and transport in order to reduce the losses of wheat from the wheat crop by spreading the mechanization in the harvest, as well as cultivating varieties characterized by the non-diversion of the ears during the circulation from agriculture to the transfer to stores or distribution to wholesalers, as well as the dissemination of audio aids and visual aids and a lot of extension centers to increase awareness of farmers importance Reducing the losses of the wheat crop and its contribution to increasing the productivity of wheat for wheat.

Analytical Study of the Food Security Position of the most Important Groups and Food Commodities in Egypt
دراسة تحلیلیة لوضع الأمن الغذائی لأهم المجموعات والسلع الغذائیة النباتیة فی مصر
The issue of food in Egypt is one of the most important objectives of the strategy of economic and social development until 2030. This should be focused on the many reasons and challenges facing this sector, the most important of which is the increase in population and the increase in food demand, under the limited available agricultural resources as land and water. It has been noticed recently that the percentage of self-sufficiency has declined, especially for the group of essential food commodities such as cereals, including wheat, maize, legumes, vegetable oils and sugar, which leads to increased reliance on imports to meet most of the food needs.
The study examined the current and future status of production capacities, consumer capacities and self-sufficiency ratios of the most important food commodities and their implications for achieving food security in Egypt. The research in the statistical analysis relied on the T-Test to compare the differences between the two study periods (2000-2006) (2007- 2014).
Based on the research results, showed that there were significant differences in total production between the two periods in wheat, legumes, fruits and sugar. This due to an increase in cultivated area or the use of biotechnological methods, such as high-yielding new varieties. As for the cultivated area, it was noticed that there were significant differences between the periods in cereals, wheat, legumes and fruits. This may be due to the negative impact of the cultivated area on the agricultural land, or the expansion of agriculture in the new lands. On the productivity, it was observed that the differences between the two periods were not significant in all commodities, except for vegetable crops, due to different varieties cultivated.
The decrease in the period of production adequacy for domestic consumption and the increase in the period of coverage of imports for domestic consumption is a negative indicator of the self-sufficiency rate in cereals, wheat, legumes, oils and sugar. In addition, Egypt has adopted its food security on imports. While the increase in the period of production adequacy and the decrease or stability of the period of coverage of imports for domestic consumption is a positive indicator of the self-sufficiency rate in maize, rice, vegetables and fruit. So the Country depends on local production to achieve self-sufficiency or stability at the same level.
Therefore, the study recommends that the importance of expanding the cultivation of cereals, legumes and oil crops by growing high productivity varieties and increasing the extension role, as well as reducing the prices of wheat and rice seeds in light of the high prices of production inputs and the preservation of agricultural land from infringement. By enforcing strict laws that criminalize encroachment on agricultural land by building on it. Finally, the implementation of the agricultural cycle, it is not possible under the rising of food prices and limited land and water resources to leave agricultural producers, especially the biggest ones produce what they like.

Analysis of the Added Value of Recycling Cotton Stalks in Egypt
تحلیل القیمة المضافة لتدویر حطب القطن فی مصر
Statistics indicate a decline in the cropping area of Egyptian cotton and cotton yield at the same time there are some problems of direct burning of cottons stalks, which leads to pollution of the environment and loss of opportunity to manufacture and achieve added value. The research is aiming to explain the financial analysis for the enterprises which dealing with cotton stalks manufacturing. The study was relying on calculation some performance indicators beside profitability ratio and efficiency ratio. In addition to, calculate feasibility study indicators such as the net present value and benefit - cost ratio and internal rate of return.
The financial indicators for the cotton waste recycling project, including the criteria for long-term repayment capacity, profitability ratio and efficiency ratio, showed the possibility of implementing the project and the project's ability to pay and fulfill its obligations.
The financial feasibility and sensitivity analysis of the project showed that the project is able to generate positive cash flows and that the internal rate of return of the project exceeds the cost of alternative opportunities reflected by the interest rate on capital deposits and estimated at 16%.
The added value of cottons stalks recycling was estimated at LE 2074 thousand as an average for the period 2011/2015. Which was reflecting the financial and environmental gains that could be made from the manufacture of such wastes.
