In Egypt, the yearly national production of sugar, 2.28 million tons, fails to cover the consumption amounted to3.25 million tons (S. C. C., 2020). As an attempt to minimize this gap, it was necessary to expand the area planted with sugar beet in the newly reclaimed lands. This work was conducted to evaluate the performance of three beet varieties under water stress to find out the best variety and its proper water requirement to get the maximum root and sugar yields per unit area in Toshka zone. Maximizing sugar production is a national target through expansion in sugar beet cultivation in the newly reclaimed soils, the specific problems of newly reclaimed soils management in particular their low water holding capacity require using an efficient irrigation system such as controlled irrigation. This technique makes it possible to relate, under water shortage condsitions, the drought stress undergone by the sugar beet plants to possible decreases in the yield or quality. The performance of beet plants under controlled irrigation with respect to yield and its components was studied by many authors among them, Tognetti et al. (2002), TWO field experiments were carried out during 2016/2017 and 2017/2018 seasons at the agricultural experimental station farm of Water Studies & Research Complex (WSRC), National Water Research Center, located in Abu-Simbel, Toshka, at the most southern part of Egypt, about 1300 south from Cairo and 280 Km from Aswan (latitude of 22 o.49N, longitude of 28 o.58E) Aswan Governorate, Egypt. These trials aimed to find out the effect of water stress rates (60%, 80% and 100% of irrigation water requirements (IWR). on yield, yield components and quality of sugar beet varieties namely Oscar poly, Farida, and Universal. Randomized complete block design, in Strip Plots arrangement, with three replications was used.
在埃及,全国每年的糖产量为228万吨,但不能满足消费量为325万吨(S. C. C., 2020)。为了缩小这一差距,有必要在新开垦的土地上扩大种植甜菜的面积。本研究通过对3个甜菜品种在水分胁迫下的表现进行评价,找出Toshka地区获得最大单位面积根产量和糖产量的最佳品种及其适宜需水量。通过在新开垦的土壤中扩大甜菜种植,实现糖产量最大化是一个国家目标,新开垦土壤管理的具体问题,特别是其低持水量需要使用有效的灌溉系统,如控制灌溉。这种技术使得在缺水条件下,甜菜植株所遭受的干旱胁迫与产量或质量的可能下降有可能联系起来。包括Tognetti等(2002)在内的许多作者对控制灌溉条件下甜菜植株的产量及其组成进行了研究。在2016/2017和2017/2018季节,在位于埃及最南部Toshka Abu-Simbel的国家水研究中心水研究综合体(WSRC)的农业实验站农场进行了两次田间试验。埃及阿斯旺省,距开罗以南1300米,距阿斯旺280公里(北纬22.49度,东经28.58度)。这些试验旨在找出水分胁迫率(60%、80%和100%灌溉需水量)的影响。研究了Oscar poly、Farida和Universal三个甜菜品种的产量、产量构成和品质。随机完全区组设计,采用条形图排列,3个重复。

DROUGHT is a worldwide problem which controls the crop productivity. Six Egyptian bread wheat varieties were crossed in a 6x6 half diallel in 2018/19 season. Parents and their fifteen F1 crosses were evaluated under normal irrigation (N), mid water stress (MS) and severe water stress (SS) during 2019/20 in three field experiments. Results showed that the analysis of variance were significant for all the studied traits. The highest mean values were recorded under all irrigation treatments as well as the combined analysis with the crosses P1x P2, P1 x P3, P1 x P5, P2 x P3, P3 x P5 and P5 x P6 for grain yield per plant. Mean squares for both general (GCA) and specific (SCA) combining ability estimates were highly significant for all studied traits. GCA/SCA ratio was greater than unity for most traits. The parental P1 exhibited positive and significant GCA effects for number of kernels per spike, grain yield per spike and grain yield per plant. The highest desirable SCA effects were obtained with the crosses P3 x P5 and P4 x P5 for grain yield per plant under stresses conditions. Positive significant heterosis were detected by the crosses P1 x P3, P2 x P3, P3 x P5, P4 x P5 and P5 x P6 for number of spikes per plant, number of kernels per spike, grain yield per spike, 1000-grain weight and grain yield per plant at N, MS, SS conditions and the combined data.
干旱是一个世界性的问题,它控制着作物的生产力。2018/19年,六个埃及面包小麦品种在6x6半双列杂交中杂交。在2019/20年的三个田间试验中,在正常灌溉(N)、中等水分胁迫(MS)和严重水分胁迫(SS)条件下对亲本及其15个F1组合进行了评估。结果表明,方差分析对所有研究性状均具有显著性。在所有灌溉处理以及与杂交组合P1x P2、P1 x P3、P1 x P5、P2 x P3、P3 x P5和P5 x P6的单株产量的组合分析下,记录了最高的平均值。一般(GCA)和特异(SCA)配合力估计的均方对所有研究性状都具有高度显著性。大多数性状的GCA/SCA比值大于1。亲本P1对穗粒数、穗粒产量和单株产量表现出积极而显著的GCA效应。在胁迫条件下,杂交组合P3×P5和P4×P5的单株产量达到了最高的SCA效果。杂交组合P1×P3、P2×P3、P3×P5、P4×P5和P5×P6在N、MS、SS条件下的单株穗数、单株粒数、单株产量、1000粒重和单株产量以及组合数据均表现出正显著的杂种优势。

Wheat (Triticum aestivum L.) is the most strategic cereal crop allover the world and Egypt. Egypt faces food shortage problems because of increment of population. Therefore, Egypt is considered one of the biggest importers of wheat all over the world. Great efforts are continually driven for increasing its productivity by means of horizontal and/or vertical planting to reduce hiatus between production and consumption.

Laboratory and wirehouse experiments were conducted in Weed Research Central Laboratory, Agricultural Research Center, Giza, Egypt to investigate the possibility of using microwave energy to prevent the germination of weed seeds and find applicable treatments which can completely devitalize quarantine weed seeds. The present work evaluated the effect of microwave on germination of six weed species: wild oats, darnel, white bursage, Giant ragweed, field bindweed and dodder and improvement of some traits of two imported crops soybean and wheat (oil percentage of soybean seeds and protein content of wheat grains), which were contaminated by these weed species. Results showed that microwave power and time required for preventing germination varied considerably among the species studied. Microwave power 80% for 15 minutes prevented completely germination percentage of wild oats and darnel and reduced germination percentage of field bindweed to 10%. The microwave power 50%, 15 minutes was enough to prevent seeds germination completely and weaken dooder quarantine. In regard to Giant ragweed and white bursage, under all microwave power treatments, there were no germination of these weeds. Microwave powers 50% for 10 minutes and 80% for 15 minutes had no effect on the oil percentage extracted from soybean seeds and protein content of wheat grains, respectively. The present results suggest clearly that the exposure to microwave can weaken quarantine weed seeds in imported soybean and wheat without injury of oil percentage of soybean seeds and protein content of wheat grains.
