Two separate experiments were carried out in a private farm in El-Matria; Dakahlia Governorate, Egypt during two successive seasons 2009/2010 and 2010/2011 to study the effect of potassium sources (potassium mono phosphate 52% K2O potassium sulphate 50% K2O and potassium citrate 38% k), levels (0, 60 and 120 kg K2O/ fed for each source), phosphorus sources (calcium super phosphate 15.5 % P2O5, rock phosphate 30 % P2O5 and phosphoric acid 85 %P2O5) and levels (0, 30 and 60 kg P2O5/fed for each source) on vegetative growth, tuber yield and chemical constituents of potato (Solanum tuberosum L.) "Spunta". Treatments were arranged in randomized complete block design in three replicates. The obtained results indicated that both potassium mono phosphate at 120 kg K2O/fed and phosphoric acid at 60 kg P2O5/fed gave the highest values of vegetative growth parameters, tuber yield and its quality in both seasons as compared with other treatments and the differences were significant.

Two field experiments were conducted during 2011 and 2012 summer seasons at Gemmeza Research Station,El Gharbia Governorate,Egypt,to study the influence of irrigation intervals and distribution of maize plants on yield and its components of imaize and rice intercropped.The experiments were coducted in strip splot design,with three replicates,where irrigation intervals were every 6 days (I1),every 10 days(I2) and every 14 days(I3) occupied the vertical plots (strip) and distribution of maize plants (one plant with 20cm between hils,two plants in hill with40cm between hills and three plants in hill with 60cm between hill) were assigned to the horizontal plots.
Results were summarized as follows;
1- All the traits of rice were significantly affected by irrigation intervals in both seasons,except, unfilled grains % in the second seasons.I1 followed by I2 treatments gave the highest values between all the characters of rice in both seasons,however, I3 treatment recorded the lowest values ,except, unfilled grains%.
2-All characters of maize were significantly affected by irrigation intervals in both seasons,except, ear height,stem diameter, number of leaves/plant and ear leaf erea in the two seasons and weight of grains/ear in the first seasons.However,all characters for maize had insignificant by distribution of plant of maize in both seasons,except,100-grain weight and grain yield/fed in the second season and plant height, ear length and weight of grains/ear in the two seasons.
3- The interaction between irrigation and distribution of maize plant had insignificant effect on all the traits of rice and maize ,except, weight of grains/ear and 100-grain weight for maize in the first seasons.
4-The highest values of Land equivalent ratio(LER)were 1.298 and1.293 in the two seasons,respectively,with irrigation intervals I1 and I2,respectively.
5-Relative crowding coefficient (RCC)was 4.21 and4.75 in the two seasons were recorded with irrigation intervals I1 and I2 ,respectively.
6-Aggressivity(Ag) indicated that rice was the dominat crop ,whereas, maize was the dominated in both seasons.
7-The highest gross return was obtained with( I1 )
Generally , it could be concluded that irrigation every 6 days and planting maize with three plants/hill with distance 60 cm between the hills could be used to obtained high grain yield for rice and irrigation every 14 days and3 plant /hill of maize at distance 60 cm for maize.

Two field experiments were conducted at Research Farm of Rice Research and TrainingCenter, Sakha, Kafr El-Sheikh, Egypt during 2010 and 2011 seasons. The study aimed to evaluate the effect of Cycocel (CCC), a mixture of Cycocel and Dicloro Iso Butyric acid (DCIB) (MLU 208), Triapenthanol (RSW041I) and Uniconazole on physiological and growth behavior of rice plants, as well as lodging degree of Sakha 104 rice cultivar(long stem cultivar that is characterized by high rate of lodging).The most important results showed that CCC did not exhibit any significant retarding effect on rice plants .All levels of MLU 208, RSW04ll and Uniconazole markedly decreased the height of plants in the terms of decreasing its lodging degree. Number of tillers/m2, flag leaf area and dry weight of rice plants were increased under all growth retardants except CCC. Degree of lodging was decreased by the application of proper levels of MLU 208, RSW04ll and Uniconazole. RSW performed better regarding lodging and reduced it to 75% of the control. All growth retardants increased the concentration of Chlorophyll A and Chlorophyll B in rice leaves but caratenoids were decreased. Nitrogen concentration in shoots and grains was increased while K was decreased. GA3 concentration in shoots was decreased but ABA was increased by the application of MLU 208, RSW0411 and Uniconazole. The high levels of growth retardants increased the weight of l000-grain, starch and protein yields. Grain yield was the highest when Uniconazole, MLU 208and RSW041Iwere applied, respectively.

Two field experiments were conducted at the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafr EI-Sheikh, Egypt, during 2010and 2011 summer seasons to investigate the effect of water qualities on some growth attributes, yield, its components and some chemical properties of four rice cultivars namely, Sakha 101and Sakha 102 (short grain and japonica type), and Giza 178 (short grain japonica / indica type) and Giza 182 (long grain indica type). A strip-plot design with four replicates was used in all experiments. The vertical plots were devoted to six water qualities as following: canal water (CW), drainage water (DW), mixed water (MW), and 1 CW: 1DW, 2CW: 1DW, and 1CW:2DW alternatively. The horizontal plots were occupied by the four rice cultivars. (Giza182, Giza178, Sakha 102 and Sakha101).
Results showed that most of growth analysis and attributed and yield components significantly increased when rice plants irrigated with drainage water treatment. In addition the drainage water treatment gave the lowest values of the K+% but gave the highest value of Na+% and Na+/K+ratio in straw and grain. The canal water treatment gave the highest values of K+% in straw and grain.
The results showed that Giza 178 is more stable under drainage water (DW) than the other cultivars. Study indicated that 2CW: I DW treatment is reasonable and save to irrigate rice plants for fields particularly soils at the end of canal.

Two pot experiments were carried out in the farm of Fac. of Agric.; MansouraUniversity during the two successive summer seasons of 2008 and 2009, to investigate the effect of soil salinity Proline treatments and some irrigation levels on plant growth, yield and biochemical constituents of Common bean (Phaseolus vulgaris L.). cv. Nebrasca.
The results obtained can be summarized as follows:-
1-Vegetative growth of common bean in term of plant height, number of leaves, fresh weight, dry weight and leaf area was reduced in case of growing on saline clay soil in both seasons.
2- Decreasing the number of irrigation gave rise to decrease vegetative growth in both seasons.
3- Proline treatment caused positive effect on the leaves.
4- The triple interaction had no significant effect on all parameters of vegetative growth in both years except leaf area in the second year.
5- Saline soil had deleterious effect on flowering parameters on both years. Likewise, decreasing irrigation number lead to injuring effect on flowering parameters while proline treatment had no obvious increase in this respect.
6- Triple interaction had no effect on flowering parameters on both years.
7- Almost NPK concentrations as well as Na, Ca, Mg were reduced in case of saline soil in both years.
8- Decreasing irrigation number decreased mineral contents of common bean leaves in both years, while proline treatment lead to increase mineral concentration in both years.
9- Saline soil had injurious effect on chlorophyll contents in both seasons. Likewise, decreasing irrigation number caused a significant decrease in pigment content in both years. Otherwise, proline treatment caused an increase in pigments content in both years.

The newly bread wheat cultivar Gemmeiza 11 has been selected from a local cross made at Gemmeiza Agricultural Research Station, Wheat Research Dept. FCRI, ARC. Egypt, using the pedigree method.
Yield evaluation was performed through 10 preliminary yield trials in 2005/ 2006, 65 advanced yield trials in 2006/2007 and 2007/2008 growing seasons, 66 verification yield trials in 2009/2010, 2010/2011 and 2011/2012 seasons in addition to 106 demonstration fields in 2011/ 2012 growing season. Results proved the superiority of the new bread wheat cultivar Gemmeiza11 compared to the commercial check cultivars Sakha 93, Sakha 94, Gemmeiza 9 and Shandaweel 1 in the most of different zones with a few exceptions . However, at the level of over all mean of the check cultivars across the locations at different climatic zones, the new cultivar mean yield exceeded significantly all the check cultivars means in both 2006/2007 and 2007/2008 growing seasons. Thus, we can highly recommend the new cultivar Gemmeiza 11 to be grown all over zones of Egypt. Moreover, the results of the verification yield trials ensure the superiority of Gemmeiza11 on the commercial wheat cultivars Sakha 93, Giza 168 and Gemmeiza 9 at North, Middle and South Delta, but at Middle Egypt its yield was less than the check cultivars Sakha 93 and Giza 168 and it was nearly equal at Upper Egypt. The obtained results of the new cultivar in the demonstration fields achieved 28.38 ard /fed in four governorates in Middle and South Delta compared to the mean of the five check cultivars which yielded 24.162 ard / fed with an increment of 4.128 ard / fed (17.46%).

High salinity stress levels decreased while pre- soaked and foliar spray applied antioxidants increased growth parameters such as leaf area , stem dry weights , and leaves dry weights.
Heigh salinity level ( 9000 mg/l ) was more effective in decreasing all growth parameters . while applied antioxidants ( pre-soaked and foliar spray) ASA and Yeast extract were more effective in increasing all growth parameters .
Moreover , it could be show that applied antioxidants partially alleviated the harmful effect of salinity stress which enhanced growth parameters .Growth parameters which increased due to applied antioxidants combined with salinity stress levels were still than control .
Salinity stress levels decreased soybean yield, and 9000 mg /l was the most effective in this respect. On the other hand, applied antioxidants (pre-soaked and foliar spray) increased seed yield of soybean plant. The data also show that applied antioxidants enhanced seed yield grown under stress condition comparing with untreated plants. This increase was less than control plant. It could be show that applied antioxidants partially counteracted the harmful effect of salinity stress on seed yield of soybean plant.

This investigation was carried out to study the effect of hand thinning, bagging and spraying with aluminum silicate on yield and fruit quality of Wanderfull pomegranate cv.
The obtained results revealed that hand thinning alone or with bagging significantly reduced the number of fruits/tree than bagging only or spraying with aluminum silicate. Yet, the effect of these treatments was on yield/tree pronounced. Since, hand tinning alone or with bagging significantly increased both fruit weight and size than the control.
The data also revealed that, bagging the fruit or spraying with aluminum silicate significantly reduced the percent of sunburn damages than hand thinning or the control. Bagging the fruits gave zero percent of sunburn. Furthermore, hand thinning with bagging or spraying the trees with aluminum silicate increased the values of soluble solids % and anthocyanin content in the skin of the fruits and in juice than hand thinning or the control. For protecting fruits of Wanderfull pomegranate from sunburn damage and improving fruit quality it is advised to use hand thinning with bagging.

The success of plant breeding operations relies heavily on the nature and extent of genetic components of variation. Thus it is imperative to have reliable estimates of such components in order to formulate an efficient breeding strategy. In the present study, ten diverse lines in F2 generation were crossed to three testers viz., Giza 86(L1) ,Austuralian(L2) and their F1 Giza86 X Austuralian (L3). The parents (lines and testers) and crosses were evaluated in randomized complete block design. Analysis of variance revealed significant differences among progenies. The deviations (cultivars L1 + cultivars L2 – cultivars 2 L3) were analyzed to provide a test of epistasis. Additive- dominance model was fitted to the data for these traits not influenced by gene interaction. The results indicated that total epistasis was insignificant for all traits. The partitioning of the total epistasis, showed significance of ( i ) types fixable part of epistasis for all traits except lint percentage, fiber strength and micronaire, while the unfixable epistasis, dominance x dominance and dominance x additive was significant for all traits except lint percentage, fiber strength and micronaire. Additive gene action played the important role for all studied traits except for lint cotton yield, upper half mean, fiber strength and micronaire. While, dominance effects were insignificant for all traits. The degree of dominance revealed that the ratio was less than unit indicated the predominant role of additively in controlling boll weight ,seed and lint cotton yield ,seed index and uniformity ratio, whilst this ratio was equal to unity for lint percentage and upper half mean showed the important of both additive and dominance properties of genes, The higher degree of dominance for fiber strength and micronaire showed over- dominance. The results showed that the dominant alleles were dispersed between testers, as hybrids did not show any proof of directional dominance for all characters.

This invstigation aimed to study the importance of morphological and anatomical traits with total phenols in leaves and bolls for insect resistance and evaluate the hybrids of Giza 88 okra leaf shaped and cultivar Giza 88 with promising cross [{G.84 x(G.70 xG.51B) x pima 62 }].The trial was conducted at Sakha Research Station during 2010 and 2011summer seasons. The results indicated that the leaves of line G.88 okra leaf characterized by narrow lobes while Giza 88 was wider lobes. Giza 88 characterized by increase for size of leaf nectaries and No. of bolls nectaries. Total phenols in leaf was high for the parent Giza 88 okra leaf, while F1 was intermediate between its two parents. The anatomical study revealed narrow difference between anatomy structural of the two parents Giza 88 and line Giza 88 okra for leaves. Anatomical features were observed, firstly the extension of the palisade tissue towards the mid vein of two parents exhibited palisade tissue, secondly the presence one in G.88 okra while G.88 had two small reverse oriented bundles separated. The F1 had not small reverse oriented bundles. The results of principal components exhibited that the two factors I and II were more importance about 87.45% of total variance, while the two factors III and IV were less importance about 21.11% of total variance .Factor I accounted for 40.32% of total variance including lobbing index , spongy tissue thickness, mid vein thickness, width of main vascular bundle and No. of xylem rows had positive loading indicates the direction of relationship between factor and variables .Factor II accounted for 38.13% including laminar thickness, spongy tissue thickness , width of main vascular bundle, No. of xylem vessels in row and total phenols of leaves and bolls, the results of anatomical traits play considerable role for resistance with that total phenols. It could be concluded that traits of laminar thickness, spongy tissue thickness, width of main vascular bundle and No. of xylem vessels in row have interrelation ship with total phenols of leaves and bolls that these traits play the main role in insect resistance. It could be concluded that traits of laminar thickness, spongy tissue, width of main vascular bundle and No. of xylem vessels in row have interrelationship to total phenols as indication for insect resistance in positive direction, no differences were noted between the structural anatomy of the two parents Giza 88 and line Giza 88 okra leaf for leaves, but the leaves of line G.88 okra varied morphologically by narrow lobes.

Two field experiments were carried out at the Experimental Farm of Sakha Agricultural Research Station in Kafr El-Sheikh Governorate at North Nile Delta Region. The experiments were conducted to study the response of onion to nitrogen fertilizer levels under different bio-organic fertilizers (compost tea and biofertilizer) as well as their interaction, on the growth and onion bulbs yield and its quality as well as storability of onion bulbs during the two successive winter seasons of 2010/2011 and 2011/2012. A split-split plot design with three replicates was used in this study. The main plots were designated to the three mineral nitrogen fertilizer levels (60, 90 and 120 kg N fad.-1), whereas foliar spraying treatments with compost tea at the same dose, 20 L fad.-1 (spraying with water; foliar spraying at 40 days after transplanting (DAT); foliar spraying at 40 and 60 DAT; foliar spraying at 40, 60 and 80 DAT and soil application, 30 DAT at rate of 30 L fad.-1) were randomly distributed in sub plots. While uninoculated and Inoculation with di-nitrogen fixing bacteria (Azotobacter and Azospirilium) were randomly distributed in the sub-sub plots.
The obtained results could be summarized as follow:
The two higher nitrogen levels (90 and 120kg N fad.-1) achieved a significant increase in vegetative growth characters (plant height, plant fresh weight, leaves dry weight/plant, bulb dry weight, plant dry weight and bulb diameter) as well as bulbs yield and quality (marketable and total bulbs yield as well as bulb diameter) as compared to the lower nitrogen rate (60 kg N fad.-1) in both seasons. The lower level of nitrogen (60 kg N fad.-1) resulted in a significant increase in TSS and dry matter % in addition to decrease weight loss% of onion bulbs at different storage periods in the two seasons.
Growth and onion bulbs yield and its quality were highest due to application of compost tea on thrice than twice batches at the same dose and other treatments. The lowest values of bulbs weight loss% at 6 months were obtained under the application of compost tea on thrice batches.
The effect of bio-fertilizer in plant height, Leaves dry weight/plant, bulb dry weight, plant dry weight, bulb diameter and bulb weight as well as bulb quality was evident in both seasons. In general, inoculation with Azotobacter and Azospirilium possitively increased all the previous characters. Total bulbs yield increased above 4.2 % in the plots treated by bio-fertilizer as compared with uninoculated treatment. Bio-fertilizer exert a significant effect on total weight loss of onion bulbs during different storage periods in the two seasons, where the lowest values were recorded with Azotobacter and Azospirilium inoculation.
The interaction between mineral nitrogen and compost tea treatments had a significant effect on most studied characters. It is clear that the application of 90kg N fad.-1x foliar spraying with compost tea at 40, 60 and 80 DAT treatments produced the highest values of these traits in both seasons.

Two field experiments were carried out at the Horticulture experimental station of Ministry of Agricultural at El-Baramon experimental farm, Dakahlia Government, Egypt., during the two successive summer seasons of 2011 and 2012 to investigate the effect of irrigation intervals, foliar application of different antitranspirants under compost rates as well as their interactions on growth and productivity of eggplant (Solanum melongena L.).
Twenty four treatments were arranged in split-split plots design, which were the simple possible combination between three rates of organic manure (0, 50 and 100% from recommended doses), two treatments of irrigation intervals (10 and 20 days) and four treatments of foliar application from antitranspirants (control, kaoline, CaCO3 and dyroton). Each treatment was replicated three times.
The most important findings could be summarized as follows:
Increasing compost from 0 to 4 ton/fed. significantly increased vegetative growth of eggplant, yield and its components, fruit quality and its chemical composition N, P, K%, Fe ppm, TSS% and VC(mg/100g) . Short irrigation intervals (10days) significantly increased all parameters under investigation. The spraying with dyroton at 3% led to significant increase in growth characters traits, N,P,K%, Fe ppm, TSS%, VC, firmness, fruit quality and yield as well as its components.
The interaction between organic manure and irrigation intervals significantly affected growth parameters, yield, fruit quality and its chemical composition except stem diameter in the 2nd season, N%, TSS% in the 1st season, K% and average fruit weight during both seasons.
Interaction effect of organic manure and antitranspirants significantly affected growth parameters, yield, fruit quality and its chemical composition except K% and stem diameter in the 2nd season; VC and average fruit weight during both seasons.
Interaction effect between irrigation intervals and antitranspirants characters under investigation had significant effect on all studied treats except TSS% in the 1st season, stem diameter in 2nd K, VC and average fruit weight during both seasons.
The interaction effect between organic manure, irrigation intervals and antitranspirants significantly affected to growth parameters, yield, fruit quality and its chemical composition except average fruit weight during both seasons.

In tow successive season's 2011and 2012 two field experiments were ducted at the Rice Research and Training Center Farm, Sakha, Kafr El-Sheikh, Egypt. The investigation was carried out to study the effect of two nitrogen levels, i.e., 165 and 220kg N/ha and six times of nitrogen application, i.e., T1 ( 2/3 as basal + 1/3 at panicle initiation ), T2 ( 1/3 as B +1/3 at mid-tillering + 1/3 at P.I ), T3 ( 1/2 as B + 1/4 at M.T + 1/4 at P.I ), T4 ( 1/4 as B + 1/4 at M.T + 1/4 at P.I + 1/4 at booting ), T5 ( 1/4 as B + 1/4 at M.T + 1/4 at BT + 1/4 at complete heading ), T6 ( 1/4 as B + 1/4 at M.T + 1/4 at P.I + 1/4 at flowering ) of Egyptian hybrid 1 rice variety. The present study was laid out into split plot design with four replications. The most important findings of this study could be summarized as follows: Increasing N-levels caused significant increases in growth, yield and its components for most studied traits. Time of nitrogen application significantly effect on growth and yield and its components for all studied traits. The best combination was adding 165kg N/ha in four splits (1/4 as B, 1/4 at M.T, 1/4 at P.I, and 1/4 at flowering) to produce optimum grain yield. From the obtained results, it can be recommended that for achievement of high yield production from Egyptian hybrid 1 rice variety when it grown under broadcast seeded rice and application of N-fertilizer at the rate of 165 kg/ha, we must splitting nitrogen fertilizer in four equal doses i.e. as basal application, at mid-tillering stage, at panicle initiation stage and last at the flowering stage under these conditions of this study.

North Carolina designs are very effective in breaking undesirable linkage and lead to creating genetic variability in a population. F1 population was obtained by crossing the two cultivars Giza 88 P1 and Australian P2. Followed crossing between F2 with the original parents, P1 and P2. The analysis of variance was highly significant for all studied traits. While, females sets were highly significant for all studied traits, which exhibit difference between them. Also, the males were significant for boll weight (BW) g /plant, seed cotton yield (SCY) and lint yield g/plant(LY) g/plant, which showed difference between them. The interactions between them were highly significant for boll weight (BW) and seed cotton yield (SCY). That showed variation background. The additive variance was higher than dominance for most studied traits. The contribution of male or female parents was more pronounced in the genetic variation. Additive components of variation were higher than dominance ones for most studied traits reflecting decreased (√D/A) values (less than unity). While the dominance portion of the genetic variation played a role for some traits reflecting higher (√D/A) values than unity for boll weight (BW) and fiber length (FL.2.5%).

Two winter Fahl berseem field experiments were conducted in two newly reclaimed soils, at Ismailia and New valley Agricultural Research stations during (2009/10 and 2010/11) seasons.This was to study the effect of planting methods and seeding rates on improving some chemical , physical and biological soil properties, as well as its productivity. The treatments comprised (1) Three planting methods i.e., broadcast, 20 and 30 cm distance between rows . (2)Applied three seeding rates, i.e., 20, 25 and 30 Kg seed fad-1 the experiments were laid-out a split plot design with three replicates.
Results showed improvements for several soil chemical, physical and biological parameters ,i.e., soil pH , O.M, available N, P and K, bulk density, total porosity , available water. Dehydrogenase and nitrogenase activity as a result of the tested treatments refer to control (broadcast method under 20 kg seed fad-1) treatment. Drilling on 20 cm apart as planting method was the best supporters in studied soil properties, particularly in the presence of 30 kg seed fad-1 treatment.
At 75th days of sowing , a positive effect of either planting methods or seeding rates was noticed, on growth characteristics of Fahl berseem plants and its composition, i.e plant height, leaves/stem ratio (LSR), forage and dry yield, total nitrogen, protein and ash contents particularly in the presence of 30 kg seed fad-1 under drilling on 20 cm rows methods gave high values compared with control.
At harvesting stage, seed yield characteristics of Fahl berseem were enhanced in response to different methods of planting and seed rates, especially with 30 kg seed fad-1 in the presence of Rows A method achieving relatively high increases compared to broadcast method treatment amended with 20 kg seed fad-1.

Two field experiments were conducted during the two successive winter seasons of 2009/2010 and 2010/2011 in a private Farm in Bani-Ebeed District, Dakahlia Governorate. The aim is to study the effect of organic, bio, mineral fertilization and their interactions on yield and quality of carrot cv. shantenay.
In general, it can be concluded that:
1- Fertilizing with compost gave the highest values of yield and quality of carrot comparing with untreated plants in both studied seasons.
2- Bio-fertilizing significantly increased yield and quality and the superiority was to the plants treated with bio-fertilizer mixture (Azotobacter, Bacillus circulans, Mycorrhiza) followed by EM.
3- Fertilizing with 100% NPK has achieved the highest values of yield however, 75% NPK gave the highest values of carrot quality.
4- The interaction among compost, bio-fertilizer (mixture or EM) and 100% NPK gave the highest values of yield however, compost plus bio fertilizer (Mixture or EM) and 75% NPK gave the superiority for yield and quality comparing with plants fertilizing with 100% NPK alone.

Two field experiments were conducted in Sakha Research Station Kafr El-Sheikh Governorate during 2010 /2011 and 2011/2012 seasons to study the effect of the combination between three nitrogen levels ( 60 , 90 and 120 kg / fed ) and four foliar zinc levels ( 0 , 0.5 , 1 and 1.5 g/ l as Zn-EDTA ) on some physiological properties , yield and quality of sugar beet.
The obtained results proved that :
The increase of N level up to 120 kg/ fed significantly increased root length and diameter as well as fresh weight/plant , leaf area , leaves zinc uptake , juice impurities content (K, Na and α-amino N) and yields of top and root (ton / fed) whereas , sucrose % , extractable sugar % , purity % and sugar yield were decreased in both seasons.
The middle dose of nitrogen (90 kg N /fed) was the superior as compared with the highest dose (120 kg N/fed) on sucrose % , extractable sugar % , purity % and sugar yield as well as gave the lowest juice impurities content and sugar losses to molasses in both seasons .
The increase of zinc level up to (1.5g/l) significantly increased all studied traits in both seasons except for N leaves content in the 1st season only as well as gave the lowest juice impurities content and sugar losses to molasses.
Fertilization beet plant at the rate of 90 kg N/fed + 1.5 g Zn/l was enough to achieve the highest sugar yield (4.22 and 4.57 ton/fed) ,whereas the increase of N fertilization at the rate of 120 kg N / fed + 1.5 g Zn/l was necessary to attain the highest yields of top (10.01 and 10.78 ton/fed), and root (28.77 and 32.60 ton/fed ) in the 1st and 2nd seasons respectively .
Therefore, it could be recommended that fertilization beet plant at the rate of 90 kg N/fed + 1.5 g Zn/l foliar application maximized sugar yield and technological parameters .
