detailed overview of evaluating 21 LTR-REMAP and 27 SSR markers in the discriminating capacity, efficiency and ability of the genetic variability among 20 genotypes in the genus Citrus . The LTR-REMAP profile displayed 1.28 fold higher value of marker index (MI) compare to the SSR profile, highlights the distinctive nature of LTR-REMAP assay. This marker was more sensitive and provided much more evidence to discriminate at low taxonomic levels, especially for Egyptian acidic, whereas, SSR can differentiate within the group level only. Intriguingly, the heatmap cluster analysis (HCA) and principal component analysis (PCA) data drew an accurate monophyletic annotations cluster in Citreneae species, offer unambiguous identification without overlapping groups between true species and related hybrids of citrus, resulted in their placement in different clades. The use of molecular technologies will help to overcome the obstacles of cultivars identification, genetic variability in the Egyptian citrus breeding.

Grape is one of the most delicious, refreshing and nourishing fruits of the world. The berries are a good source of sugars and minerals as Ca, Mg, Fe, and vitamins as B1, B2 and C (Senthilkumar et al., 2018). Thompson seedless grape is the most important table grape cultivar grown in Egypt especially in Delta region. It is a table grape and for making raisins and also it is an important cultivar for export.

Contamination by HMs has emerged with the industrial revolution and then sharply increased in urban due to due to increased population activity and in rural areas due tointensive agriculture production to meet food demand of a growing population. Intensive agricultural pollution arises from both natural (geological) and anthropogenic activities i.e., various stationary and mobile sources (Bilos et al., 2001). Agricultural amendments e.g., sewagesludge, mineral synthetic fertilizers and pesticidesrelease large quantities of HMs (Anagawa et al., 2019), exceeding critical limits i.e., 60mg/kg Pb and 70mg/kg Cu in the soil according to FAO/WHO (2001).This is acutely evident inEgypt, especially in areas adjacent to the highways, domestic wastewater and industrial zonewhich pose a critical concern to plants,environment and human at the end of the food chain. In northeastern of the Delta, particularly in Talkha, an industrial and agricultural city, the soil is heavy in texture with relatively high pH, low organic matter and contaminated by copper and lead, besides low quality irrigation water which was a mixture of industrial waste from El Delta Fertilizers Co. and sewage and agricultural wastewaters. THE PRESENT study was carried out during the summer seasons of 2017 and 2018 in Talkha city, Dakahlia Governorate, Egypt near El-Mansoura-Damietta highway and El Delta Company for Fertilizers and Chemical Industries, where lead (Pb) and copper (Cu) levels in the soil exceed the permissible levels. Therefore, the aim of this study was to alleviate the adverse effects of heavy metals (HMs) on tomato plant (Solanumlycopersicum L.) Super Strain B F1. Twelve treatments were conducted which were the interactions between two silicon (Si) foliar spraying (without or 300 ppm Si) and six soil amendments : 100% chemical fertilizers (CF), 50% farmyard manure (FYM), 100% FYM, 100% CF+ Trichoderma spp. (T.), 50% FYM + T. and 100% FYM + T. Data indicate that Pb and Cu were accumulated in tomato organs to hazardous levels in the following descending order : roots > shoots > fruits and shoots > roots > fruits, respectively which consequently severely reduced tomato plant growth and fruit yield and fruit quality. Results also, showed that the application of Si treatment sole or in combination with soil amendments markedly enhanced plant height, dry weight, total chlorophyll, number of fruits/plant, total yield/fed, Vitamin C, acidity %, TSS and taste index, where as, reduced Pb and Cu concentrations in different plant organs, bio-concentration factor (BCF) and translocation factor (TF). However, Si + FYM + T. treatment was superior in these respects, therefore increased the net return. Also, negative correlations were obtained between fruit yield and BCF of Pb or Cu and between taste index and TF of Pb or Cu.

Nano-fertilizers are effective substitutes for the traditional ones. However, to what extent can nano hydroxyapatite (NHA) and nano-boron oxide (NBO) be suitable substitutes for calcium superphosphate(CSP) and boric acid (BA)? The answer required conducting a field experiment on broccoli (Brassica oleraceavar. italica) cultivated on a heavy claysoil for two successive seasons of 2016/2017 and 2017/2018.The nano form of NHA surpassed CSP by 14.2 to 17.8 % for leaf area and 13.6 to 15.8% for total head yield. Foliar spray with NBO increased leaf area, head yield and vitamin C content in heads as compared with BA. P and B contents in broccoli shoots receiving the nano forms surpassed those of the conventional fertilizers. Combined application of the two nano-fertilizers surpassed the combined application of the two conventional fertilizers by 16.0 %. Values for yield and yield components were significantly positively correlated with P and B contents in plant shoots and heads.

Pomegranate (Punica granatum, L) has been mentioned in the Hallowed Quran and it was cultivated in Egypt a long time ago. Pomegranate is a popular fruit and considered one of the most valuable fruits for its nutritive, industrial and medicinal values. (Swain, 1965 and Nasacheva, 1973). Recently, in Egypt, pomegranate cultivated area increased rapidly from year to another and reached about 34.27 Hectare (85676 feddan) with total fruit production of 381426 metric tons, according to (M.A.L.R. R.2017). Fertilization plays an important role during the growing season to reach an economical yield with good fruit quality. In Egypt, usually apply mineral fertilizers especially nitrogen fertilizers in very excess quantities (Eman, 2006). Mineral fertilizers, pesticides and other chemicals used in production not only have great harmful effects on the environment but also they could change the composition of fruits and vegetables and harmful residues may remain in fruits (Bogatyre, 2000). Organic fertilizers became a promising alternative to mineral fertilizers to decrease of pollution and to produce more safe yield (Blake, 1990). Farmers apply organic N not only to improvement of soil physical, chemical and biological properties but also to increase in the availability of other nutrients (Yagodin, 1984, Lindemann & Cardenas, 1984, El-Salhy et al., 2002, Diab, 2006 and Almadini TO EVALUATE efficacy of fertilizing with different combinations of organic fertilizers on yield, fruit quality and nutritional status of “Wonderful” pomegranate trees, a field experiment was carried out in “Hegazi farm” located in Cairo to Alexandria desert road, Egypt. during three growing seasons 2016, 2017 and 2018 on nine years old pomegranate trees cv. ‘Wonderful’ growing in sandy loam soil under 62% shading. Nitrogen requirements were added from different combinations of commercial organic fertilizers such: Compost (COM), Chicken Manure (CHM), Cattle Manure (CAM) and Mineral Fertilizer (MF) by the rate 40 kg actual N fed-1with or without humic acid addition. The experiment consists of ten treatments spread in a randomized complete block design with five replicates. Fertilizing with (50% (CHM)+ 50% (COM)), (50% (COM) + 50% (CAM) and (33.3% (CHM) + 33.3% COM) + 33.3% (CAM) + humic) enhanced vegetative growth, yield. Fertilizing with (50% (CHM) + 50% (COM) + humic) and (33.3% (CHM) +33.3% (COM) +33.3% (CAM) + humic) improved fruit physical properties like (arils weight, juice weight and juice volume). Fertilizing with, (50% (COM) + 50% (CAM) + humic) gave the highest content of TSS%, TSS/acid ratio & ascorbic acid and least content of acidity. So it could be recommended by, fertilizing “Wonderful” pomegranate trees by one of these treatments (50% CHM +50% COM + humic), (50% COM +50%CAM+ humic) and (33.3% CHM+33.3% COM+33.3% CAM +humic) by the rate of 40 kg actual N fed-1to improve yield, fruit quality and nutritional status.

Kohlrabi (Brassica oleraceae var. gongylodes) is an edible plant belongs to Brassicaceae family. Kohlrabi is considered as a cole crop with enlarged stem (knob) as an edible portion. Because of the high contents of knobs in vitamin C, potassium and antioxidant substances, enormous nutritional and medicinal values have been highlighted (Dhaliwal, 2017). It is widely cultivated in European and American countries, having a short growing season with high exportability. However, no available data about cultivation and consumption of this valuable vegetable in Egypt even a very limited area was cultivated randomly.
