Cauliflower Water Productivity, Growth, and Yield in Response to Irrigation Management Using Different Water Sources إنتاجية المياه ، نمو وحاصل نبات القرنبيط تحت ادارة نظام الري باستخدام مصادر مختلفة للري
The present study aimed to estimate water use efficiency for cauliflower crop production using different irrigation water sources. This research was carried out during the seasons of 2018-2019 in the Research Field Station of the College of Agricultural Engineering Sciences, University of Sulaimani. The experiment was laid out in randomized complete block design with three treatments and three replicants. The cauliflower plants were grown under a surface irrigation system. The three treatments were: (I1) River water irrigation and (I2) Sewage water irrigation during the entire growing seasons from planting to harvest, and (I3) alternate irrigation which meant one river irrigation water followed by two sewage irrigation water, alternatively. The results showed that the means of irrigation water requirements were 441, 457, and 427 mm for river water, sewage water, and alternate irrigation, respectively. It is observed that I3 had significantly higher WUEc (6.33kg m-3) and compared with other treatments I1 and I2 (5.13 and 4.27 kg m-3), respectively.

Effect of Micro-Nutrients Foliar Application on Yield and Quality Traits of some Canola Genotypes Under Different Environmental Conditions تأثير الرش الورقي بالعناصر الصغرى علي انتاجية وجودة محصول بعض التراکيب الوراثية من الکانولا تحت ظروف بيئية مختلفة
In order to evaluate some canola genotypes performance to micro-nutrient foliar spraying. Four field experiments in two different soil types i.e. clayey (S1) and loamy sand (S2) at two experimental farms, Faculty of Agriculture, Fayoum University, Egypt in the winter season of 2017/18 (Y1) and 2018/19 (Y2). Six canola genotypes i.e., G1 (35/9), G2 (26/18), G3 (Duplo), G4 (Drakkar), G5 (Hanna) and G6 (Serow4) and three micro-nutrient rates were studied. The Y1 has higher significant values of plant height, pods dry weight, seed, oil and protein yields, Mn, Fe and Zn seed content. The S1 significantlyexceeded S2 for most studied traits. The G1 (35/9)line followed by G6 (Serow4) variety recorded significantly the highest values of most growth traits, seed yield and its components as well as seed content of Mn, Fe, Zn, oil and protein. Foliar application of micro-nutrients by the highest rate significantly surpassed tap water (control) for all studied traits. The correlation coefficients showed that the seed, oil, and protein yields have significantly positively correlated with most studied traits. There are three traits, i.e. pods dry weight plant-1, plant height and number of pods plant-1 were significantly (P≤ 0.001) participated in variation in seed yield ha-1. The Results suggested that the G1 line could be promising genotype, have a stable yield in the various environments (years and soil types) and more responsive to micro-nutrients nutrition under different environmental conditions.

Effect of Ploughing Depths, Irrigation Intervals and Plant Densities on Sugar Beet Yields and Quality تأثير عمق الحرث وفترات الري والکثافة النباتية على انتاجية وجودة نبات بنجر السکر
Under field conditions, two trials were performed through two years of 2015/2016 and 2016/2017 at Galia Al-Kobra, Belqas district, Dakahlia Governorate to investigate the effect of four ploughing depths (15, 20, 25 and 30 cm), two irrigation intervals (every 3 and 5 weeks) and three planting hill spacings (15, 20 and 25 cm) resulted in three plants densities (46666, 35000 and 28000 plants/fed) on sugar beet Oscar poly cultivar growth, yields and quality. The factors were set in s strip-split plot design with 4 replicates. Four ploughing depths, 2 irrigation intervals and 3 planting densities were occupied randomly in the vertical, horizontal and sub-plots, correspondingly . The attained outcomes pointed out that all factors under study individually significantly influenced leaf area index, root fresh weight/plant, dimensions of roots and yields/fed as roots and sugar. Contrary of that, % of sucrose and purity were insignificantly affected by ploughing depth treatments in mutually time of years. All the interactions among the three studied factors significantly affected the above mentioned traits in both years. From the achieved results, it could be suggested that ploughing the soil at 30 cm depth and irrigated sugar beet plant every 3 weeks at the medium planting density (35000 plants/fed) resulted from sowing on 20 cm a part between hills to give the utmost yields and quality beneath the ecological circumstances of this study.

Impact of Foliar Application with Iron, Zinc, Silicon Nano Particles and Yeast on Growth, Yield and Water Use Efficiency of Tomato Plants under Water Stress Conditions تأثير الرش الورقي بجزيئات نانو الحديد والزنک والسيليکون والخميرة على النمو والمحصول وکفاءة الاستهلاک المائى لنباتات الطماطم تحت ظروف الإجهاد المائى
Two filed experiments were conducted during the two summer seasons of 2015 and 2016 in a private Farm at Gemiana village near Belqas City Dakahlia Governorate, Egypt, to study the effect of interaction between deficit irrigation water (60%, 80%, 100% of ETc) and some foliar spray treatments (nano iron, nano zinc, nano silicon and yeast extract) on plant growth parameters, chemical composition of leaves as photosynthetic pigments (Chl. a, Chl. b, total Chl. a+b), leaf mineral percentages (N, P, K) proline, yield and water use efficiency (WUE) of tomato plants (Fayruz hybrid) under drip irrigation system. A strip-plot design with three replicates was used. The vertical plots were allocated to the deficit irrigation, whereas the horizontal-plots were devoted to foliar spray treatments. Results revealed that the interaction among irrigation tomato plants at the level of 80 % Etc and spraying with different nano particles at different concentration or yeast extract significantly increased all aforementioned parameters, meanwhile deficit irrigation water treatments improved leaves proline content and WUE in both growing seasons. The best interaction treatment for increasing plant growth parameters, chemical constitutes of leaves as photosynthetic pigments (Chl. a, Chl. b, total Chl. a+b) leaf mineral percentages (N, P, K) early and total yield is irrigation treatment with 80 % Etc and spraying with nano Si at 12 ppm and can be recommended to increase growth and productivity tomato plants of under similar conditions of this study.

Crop Assessment and Phenotypic Correlation and Stability of New Sugarcane Genotypes under Different Seed Rates التقييم المحصولي والارتباط والثبات المظهري لتراکيب وراثية جديدة من قصب السکر تحت معدلات تقاوي مختلفة
Two field experiments were conducted at Shandaweel Agric. Res. St. (latitude of 26.33° N and longitude of 31.41° E), Sohag Governorate, Egypt in 2017/2018 and 2018/2019 seasons to assess the yield and quality of the new sugarcane varieties viz. (G.2003-47 and G.2004-27) and G.2005-47 promising genotype, compared to the commercial variety GT.54-9 as affected by three seed rates (1.0, 1.5 and 2.0 drills of three-budded cane cuttings). A split plot design was used. Planting sugarcane using 2.0 drills of cuttings improved most of the studied traits. Significant improvements in brix%, sucrose% and sugar recovery% (SR%) were recorded in case of growing using 1.0 drill, while using 1.5 drill resulted in the highest millable cane (MC) weight. The commercial GT.54-9 variety was superior in most of the studied traits. Variety G.2003-47 was superior in brix%, sucrose% and SR%, meanwhile, variety G.2004-27 attained the highest number of MC/fed. The interaction between the studied factors markedly affected all the studied traits, except MC height, in both seasons. Millable cane weight exhibited positive and high significant correlation with MC height and diameter. However, it was negative correlation between number of MC/fed with MC diameter, brix and sucrose%. Variety G.2004-27 showed broader adaptability for all studied seeding rates. Based upon the previous results, planting sugar cane variety GT.54-9 using 2.0 drills cutting seed setts could be recommended to attain the highest cane yield, while, planting variety G.2003-47 using 1.5 drill is recommended to get the maximum sugar yield under conditions of the present work.

Inducing Salinity Tolerance in Mango (Mangifera indica L.) Cv. “El-Gahrawey” by Sodium Silicate Pentahydrate and Glycine Betaine تعزيز تحمل شتلات المانجو صنف ̋ الجحراوى ̏ للملوحة بواسطة سليکات الصوديوم والجليسين بيتين.
The investigation was done to study the effect of Sodium Silicate Pentahydrate (Si) and Glycine betaine (GB) on enhancing salt tolerance of Mango seedlings “El-Gahrawey” cultivar grown under salinity stress. The results indicated that the application of sodium chloride (NaCl) induced a significant reduction in growth parameters and plant development, increasing salinity levels decreased plant leaf number, stem diameter, and stem length as well as fresh and dry weight of leaves. Also, a reduction of chlorophyll was observed in salt-affected plants. Besides, salt stress lead to an accumulation of sodium Na+ and a decrease in N, P, K+, Ca2+, and Mg2+ concentrations in mango leaves. However, Combinations of Si and GB sprays was the most effective treatment in alleviating the negative impacts of salt stress in mango, this treatment increased significantly most of the tested parameters under salt stress.

Influence of Foliar Application with Nitrogen and Boron on Growth and Yield of Cauliflower تأثير الرش بالنتروجين والبورون على نمو ومحصول القنبيط
Appropriate nutrition in early autumn season under high temperature conditions has a major effect on cauliflower yield and quality. Thus two field experiments were conducted during autumn 2018 and 2019 seasons at a private farm in Demiana village, Belqas district, Dakahlia governorate to investigate the influence of foliar application with nitrogen micro carbon (NMC) at 0, 300, 600 and 900 ppm) and boron (B) at 0, 10 and 20 ppm and their interaction on vegetative growth characters, leaves chemical contents, curds yield and quality. This study contains 12 treatments with three replicates arranged in split plots in a complete randomized block design. Nitrogen micro carbon was assigned in the main plots, whereas the boron was randomly located in sub plots. Obtained results cleared that interaction impact between NMC and B significantly affected on vegetative growth (plant height, foliage fresh weight, No. of leaves, leaves fresh weight, leaves area and leaves dry matter), chemical contents of leaves (N, P, K, chlorophyll a, chlorophyll b and carotenoids), curds yield and physical characters (curd weight, diameter compactness rate, yield and hollow stem) and curds quality (dry matter, Vit. C, acidity and TSS). In this concern, combination between nitrogen micro carbon at 600 ppm and Boron at 20 ppm gave the highest values of previous parameters except hollow stem percentage where between NMC at 0 ppm and B at 20 ppm gave the lowest percentage of hollow stem.

Efficacy of some Integrated Weed Control Treatments on Sugarcane Ratoon Productivity "فاعلية بعض معاملات المکافحة المتکاملة للحشائش على إنتاجية القصب الخلفة"
Two field experiments were carried out at Shandaweel Agricultural Research Station (latitude of 26 33° N and longitude of 31 41°E), Sohag Governorate, Egypt in 2018/2019 and 2019/2020 seasons to study efficacy of some integrated weed control treatments (removing or burning cane trash; hoeing and Ready Peck, Clomdi, Lumax, Garlone herbicides) on yield and quality of sugarcane 1st ratoon of G.2003-47 variety (Giza-3). A randomized complete block design in a split-plot arrangement with three replications was used. The results showed that the removal of plant cane trash out of the field resulted in significant increases in millable cane height, number of millable canes, cane and sugar yields/fed of the 1st cane ratoon crop. However, cane trash treatments had insignificant effect on weed traits, millable cane diameter and juice quality. The applied herbicides and hoeing (twice) negatively and significantly affected fresh, dry weight of both grassy and broad-leaved weeds and their total weight, compared to un-weeded plots. The applied herbicides and hoeing appreciably increased millable cane height, number of millable canes, sucrose%, sugar recovery%, cane and sugar yields. Hoeing was the most effective in weed eradication, resulting in higher sugarcane traits, compared with the other treatments. The effects of interactions among the studied factors on sugarcane and/or weed traits were discussed. Under conditions of the present study, the removal of trash of the plant cane crop out of the field, with hand hoeing twice can be concluded to attain the highest cane and sugar yields of 1st ratoon cane crop.
