The purpose of this study was to estimate and compare the genetic gain obtained from the Smith-Hazel index model of selection index with direct selection to enhance the selection efficiency of superior promising families in early segregating generations of the durum wheat population. Two methods of selection were evaluated, namely, direct selection and indirect selection, by the selection index in the yield and its components. A comparison of mean performances for different traits among the four generations (F 2 , F 3 , F 4 , and F 5 ) revealed an increase in mean values for most traits with advanced generations from F 2 to F 5 , with some exceptions due to environmental factors. PCV and GCV were generally larger in magnitude for all studied traits in the F 2 generation as compared with the advanced generations F 3 , F 4 , and F 5 , indicating that the magnitude of the genetic variability persisting in this material was sufficient for providing a rather substantial amount of improvement through the selection of superior progeny. High heritability values over 50% for most studied traits across generations indicate a high magnitude of genetic variability and possible success in selection in early generations. Nine out of eleven selection indices were more efficient than direct selection for improving GY/P in the F 2 population. The highest predicted genetic gain from F 2 generation for GY/P was observed when selection index (I W123 ) was followed by selection index (I W2 ) and by selections for (I W12 ), (I W23 ), (I W1 ), and (I W3 ). Selection index (I W123 ), followed by I W12 and direct selection (I XW ), gave the highest actual genetic gains from the third generation for trait GY/P. Most indices showed a high discrepancy between predicted and actual genetic gain as GY/P; this was due to the interaction between genetic effects and large effects of environmental factors. The maximum predicted genetic advance from F 3 and F 4 generations for GY/P was achieved when selecting directly (I XW ) in F 3 followed by selection indices (I 123 ). While maximum actual genetic advance from F3 and F4 generations for GY and P was achieved when using selection indices (I 123 ), followed by (I W2 ), and then direct selection (I xw ). Deviations of the actual genetic advance from the predicted advance from the F3 and F4 generations showed positive and large values in most procedures.

This research aims to study the ability to see from abroad in its most important import markets, and it relied on the method of descriptive and quantitative statistical analysis through the method of descriptive and quantitative statistical analysis through the method of regression analysis as well as the semi-optimal demand model and the Marquee brand, and by studying the instability index that the price was more Volatile and significant value, the value was more stable in the average period (2001-2020), as a brand during the period (2001-2020), as it is clear that the markets of Holland, Saudi Arabia and Kuwait are able to absorb the largest possible amount of large exports, the market share can be expanded For the Egyptian onions in these markets, it is clear the possibility of increasing the market share of Egyptian onions in the UAE market and the possibility of reaching the quantities exported to this market . It is clear from the results of the semi-optimal demand model for the Saudi market. It is clear from the spending flexibility that an increase in the total real spending on onions in the Saudi market by about 1% leads to an increase in spending on onions in the Egyptian market by about 1.51%, which indicates that Egyptian onions are a necessary commodity in the Saudi market. About the Russian market, it was found that an increase in the total real spending on onions in the Russian market by about 1% leads to an increase in spending on onions in the Egyptian market by about 1.29%, which indicates that Egyptian onions are a necessary commodity in the Russian market. The research recommends focusing on the markets in which the demand for Egyptian onions is increasing, such as the Saudi, Dutch, Kuwaiti and Russian markets, as well as studying the prices of competing countries in order to maintain Egypt’s competitive position in the markets that occupy the center stage for Egyptian onion imports and to maintain that prices do not rise to maintain traditional markets and open markets In addition to paying attention to the external market, in terms of needs, quality standards, export dates, and desired items to ensure the continuity of the exported quantities and work to increase those quantities, as well as providing exporters with data and information on the required quality and conformity with international standards in order to achieve a competitive advantage for the crop globally .

Two field experiments were carried out at the research farm of west-west El-Minya, (latitude of 28.24 o N and longitude of 29.59 o E with 134 meters elevation above sea level), El- Minya Governorate, Egypt, in the 2019/2020 and 2020/2021 seasons to find out the effect of magnetizing irrigation water and foliar application of boron-sugar alcohol complex on growth, yield, and quality of sugar beet ( Beta vulgaris var. saccharifera, L.), under drip irrigation system in sandy soil. This work included ten treatments representing the combinations of two types of irrigation water [irrigation with well water (the conventional practice) and watering with magnetized well water] and five levels of boron-sugar alcohol complex (zero, 50,100,150, and 200 ppm/fed), equivalent to (zero, 2.36, 4.72, 7.08 and 9.44 cm 3 ) of the compound containing 15% boron, which was sprayed twice at 65 and 85 days from sowing. A split-plot randomized complete block design in arrangement with four replications was used. Results revealed that sugar beet plants irrigated with magnetized well water had better performance and productivity than those received well water without magnetization. Leaf area index, photosynthetic pigments, root criteria, percentages of sucrose, extracted sugar and quality index, as well as root, top, and sugar yields/fed increased compared to that received non-magnetized well water. However, impurities contents and sugar lost to molasses% were insignificantly affected in both seasons. Spraying beets with 150 and/or 200 ppm boron-sugar alcohol complex gave the highest values of sucrose, extracted sugar percentages, quality index, root, and top yields/fed in both seasons, as well as sugar yield/fed, in 1 st season while sodium and alpha-amino N contents decreased, in both seasons. On the other hand, spraying with 200 ppm boron-sugar alcohol complex increased leaf area index, photosynthetic pigments, root criteria, and root potassium content in both seasons as well as sugar yield/fed in the second one compared with those sprayed with 150 ppm. The combination of irrigation with magnetized well water + spraying with 150 and/or 200 ppm boron-sugar alcohol complex recorded the highest values of the root, top, and sugar yields/fed in both seasons.
在2019/2020和2020/2021两季，在埃及El-Minya省west-west研究农场(纬度28.24 o N，经度29.59 o E，海拔134 m)，研究磁化灌溉水和叶面施用硼糖醇配合物对沙质土壤滴灌系统下甜菜(Beta vulgaris var. saccharifera, L.)生长、产量和品质的影响。这项工作包括10个处理，代表两种灌溉水的组合[用井水灌溉(传统做法)和用磁化井水灌溉]和5个水平的硼糖醇复合物(0、50、100、150和200 ppm/次)，相当于(0、2.36、4.72、7.08和9.44 cm 3)含15%硼的化合物，在播种后65天和85天喷洒两次。采用4个重复的裂图随机完全区组设计。结果表明，磁化井水灌溉甜菜植株的生长性能和生产能力优于未磁化井水灌溉甜菜植株。叶片面积指数、光合色素、根标准、蔗糖百分比、抽提糖和品质指数、根、顶、糖产量/日均较未磁化井水提高。然而，杂质含量和糖蜜损失率在两个季节都没有显著影响。喷施150 ppm和/或200 ppm硼糖醇配合物的甜菜，蔗糖、抽提糖率、品质指数、根产量、顶产量/饲用量以及糖产量/饲用量在第1季均最高，钠和α -氨基氮含量在第1季均下降。另一方面，与150 ppm相比，200 ppm硼糖醇配合物在两个季节的叶面积指数、光合色素、根标准和根钾含量以及第二个季节的糖产量/采食量均有所增加。磁化井水灌溉+ 150 ppm和/或200 ppm硼糖醇复合喷药组合在两个季节的根、顶和食糖产量均最高。

The research aims to estimate the efficiency of the agricultural technical and economic resources used in the production of the faba bean crop in Ismailia Governorate and to determine the optimal combination of productive resources used in production. a questionnaire specially prepared for this purpose, where 100 farms were selected randomly: 30 farms (one feddan or less), 35 farms (greater than one feddan and less than three feddans), and 35 farms (three feddans). It was found that there are 30 farms that achieved full technical competence, where they were distinguished with a constant return on capacity, which means that the actual combination of resources is the same as the optimum, where the capacity efficiency reached one. 65 farms were characterized by an increase in the return on capacity, meaning that these farms could increase the number of resources used and obtain a greater amount of production, while 5 farms were characterized by a decrease in the return on capacity. capacity, which means reducing the resources used in it to achieve full technical efficiency, as it was found that 34 farms consider their farms self-sufficient (self-referential), and 66 farms are considered farms that are a reference for other farms. By estimating the economic efficiency in the case of capacity change, it was found that the farms who achieved economic efficiency were 2 farms with a rate of 7% of the total farmers of the first category, and for the second category, it was found that the farmers who achieved economic efficiency were 2 farms with a rate of 6% of the total farmers of the second category, while the farmers of the third category who achieved economic efficiency were 4 farms with a rate of 11% of the total farmers of the third category, meaning that the first, second, and third category producers can achieve the same level of production at a cost less than the actual costs by 12%, 9%, and 9%, respectively. As it was shown from the estimation of the optimal quantities of resources that achieve economic efficiency in the case of a change in the yield of capacity in relation to the amount of seeds, the quantity of seeds must be reduced by about 5 and 10 kg/feddan for the first and second, respectively, as well as reducing the number of workers by about 2, 6, and 8 workers/feddan for the first, second, and third, respectively, while the amount of nitrogen fertilizer should be increased by about 10 and 5 kg/feddan for the first and second categories, and 5 kg/feddan in the third category. as well as an increase in the amount of phosphate fertilizer by about 50 kg/feddan for the first category; in the third category, regarding the amount of irrigation water, the amount of irrigation water should be increased by about 500 m3/feddan and 200 m3/feddan for the first and second categories, respectively.

Since ancient times, many edible crops have been planted in Egyptian lands that have become an essential part of daily eating habits; faba bean (Vicia faba L.) became one of these crops and also became the most important food legume crop in Egypt. This experiment was carried out in the two winter seasons (2020/2021 and 2021/2022) at Tag El-Ezz Research Station using two varieties of faba bean (Giza 843 and Nubaria 5) and adding sorbitol (sugar alcohol) and boron, individually or combined via seed soaking and foliar application, to investigate the ability to improve seed yield and quality. A split-plot design was used where faba bean varieties were in the main plots while sorbitol and boron treatments were in sub-plots. Results indicated that the Giza 843 variety was better. Pronounced differently, differences among studied treatments are either combinations or singles. The best performance was recorded with the soaked Giza 843 variety with treatments (sorbitol at 10.0 g L-1 and boron at 10.0 mg L-1) and simultaneously foliar application with the same rates during plant life. Generally, it can be concluded that the seed soaking and foliar application of sorbitol and boron were successful ways to improve field emergence and optimize seed yield (quality and quantity) of both faba bean ( Vicia faba L.) varieties Giza 843 and Nubaria 5.
自古以来，埃及土地上种植了许多可食用的作物，这些作物已成为日常饮食习惯的重要组成部分;蚕豆(Vicia faba L.)成为这些作物之一，也成为埃及最重要的食用豆类作物。本试验于2020/2021和2021/2022两个冬季(吉萨843和努巴利亚5)在Tag El-Ezz研究站进行，并通过种子浸泡和叶面施用单独或联合添加山梨醇(糖醇)和硼，以研究其提高种子产量和品质的能力。采用裂区设计，蚕豆品种在主区，山梨醇和硼处理在副区。结果表明，吉萨843品种较好。不同的是，被研究的治疗方法之间的差异要么是组合的，要么是单一的。吉萨843浸泡后，在植株生长过程中，山梨醇用量为10.0 g L-1，硼用量为10.0 mg L-1，叶面同时施用量相同，表现最佳。综上所述，浸种和叶面施用山梨糖醇和硼是提高吉萨843和努巴利亚5大田出苗率和优化种子产量(质量和数量)的成功方法。
