Two field experiments were conducted at the Experimental Station Farm in Kalapsho and Zaian region, Fac. of Agric., MansouraUniv. during 2004/2005 and 2005/2006 seasons to determine the effect of nitrogen, phosphorus and potassium fertilizers levels as well as their interactions on growth, seed yield and its components as well as quality of oil seed rape (canola). Pactol cultivar under conditions of newly reclaimed sandy saline soils as in Kalapsho and Zaian region, Dakahlia Governorate was used. The main results of this study can be summarized as follows:
Increasing nitrogen fertilizer levels from 45 to 60 and 75 kg N/fed significantly increased plant height, number of primary and secondary branches/plant, number of pods/plant, pod length, number of seeds/pod, 1000-seed weight, seed yield/fed and in both seasons. However, oil % markedly reduced by increasing nitrogen levels.
Phosphorus fertilizer levels markedly increased all studied characters in favour of 30 kg P2O5/fed in both seasons, except for oil % only in the first seasons.
Increasing potassium levels up to 24 kg K2O/fed significantly increased plant height, number of primary and secondary branches/plant, number of pods/plant, pod length, number of seeds/pod, 1000-seed weight, seed yield/feddan and oil % in both seasons. Except for number of secondary branches/plant in the first season, 1000-seed weight in the second season and oil percentage in both seasons where the differences between K levels did not reach the level of significance.
It can be concluded that using NPK fertilization at 75 kg N + 30 kg P2O5 + 24 kg K2O/fed in order to maximizing seed and oil yields of canola under the environmental conditions of Kalabsho and Zayian district – Dakahila Governorate.

Two field experiments were carried out at El-Gemmeiza Agric. Res. Station, Gharbia Governorate, during 2005 / 2006 and 2006 / 2007 seasons, to study the effect of transplanting canola seedling at different ages (30, 45 and 60 days as well as direct seeding) and preplanting soaking canola transplants, in GA3, IAA and NAA and without dipping (control treatment), on growth, yield and yield attributes of canola seeds (Srew 4). The treatment took of stages of 30 days from seeding the seeding were soaked for 24 hours just before transplanting using control without soaking. Results indicated that, the differences between transplanting treatments as well as direct seeding for number of days to 50% flowering, plant height (cm), number of branches / plant, fruiting zone length, seed yield / plant (g), 1000 – seed weight (g), seed yield kg/fad. and oil seed percentage were significant in the two seasons. Transplanting canola plants at 45 days old gave the highest values for all attributes studied in both seasons, except No. of branches/plant and oil percentage. While, transplanting after 30 days produced the highest values for number of branches / plant and seed oil percentage in the two seasons. The minimum values of the above attributes studied were obtained by sowing seed directly. IAA application significantly increased all attributes studied in first and second seasons. Interaction between transplanting and soaking treatments showed significant increase for all attributes studied except number of branches / plant, 1000 – seed weight (g) and seed oil percentage in both seasons.

Two field experiments were conducted during 2006 and 2007 summer growing seasons at Ismailia Agric. Res. Station, to study the effect of phosphorus treatments (soil at the rate of 0, 31 kg P2O5 and foliar application of 2% P2O5) as well as bio-fertilizer treatments (0, Phosphorein alone, Phosphorein + Rizobactrein, Phosphorein + Microbein and Phosphorein + Nitrobein) on yield, yield components and seed oil percentage of peanut (Arachis hypogaea, L.) Giza 6 cultivar. Results indicated that soil application of 31 kg P2O5/fad. gave the highest values for number and dry weight of nodules/plant (mg), phosphorus content, number of pods/plant, pod yield/plant (g), seed yield/plant (g), 100 – pod weight (g), 100 – seed weight(g), pod yield/fad (kg) and seed yield/fad. as well as seed oil percentage in both seasons. Also results showed that all inoculating treatments increased number, dry weight of root nodules and phosphorus content but with varying degrees compared with inoculation with phosphorein alone. In that respect bio-fertilizer treatments were descendingly arranged as follow: Phosphorein + Microbein > Phosphorein + Notrobein > Phosphorein + Rizobactrein. Co-inoculation with Phosphorein + Microbein exhibited superiority for the above mentioned parameters over the other co-inoculation treatments. Similar findings were obtained for yield and its components when inoculation with Phosphorein + Microbein produced pod yield/fad. higher 38.14 and 39.58% above the control treatment in both seasons. Interaction effect between phosphorus and bio-fertilizer treatments was significant for all studied attributes in both seasons, dry weight of nodules/plant, phosphorus content, seed yield/plant, 100 – seed weight and shelling percentage. It was shown that soil application of 31 kg P2O5 with combination of Phosphorein + Microbein gave the highest values for yield and yield attributes in both seasons.

Generally It has been accepted that the apomictic nature of nature of garlic clones could affect its cytological and genetical features as a result of accumulation of certain somatic mutations. Thus, the aim of this study is to examine some of the cytological (karyotyping, mitotic index and mitotic abnormalities) and isozyme characteristics of five garlic genotypes cultivated in Egypt (Baladi , Chinese , Chinese , 30-4 , Chinese 31-1and Chinese 31-3).Relative chromosome lengths and centromere position of these genotypes revealed insignificant difference in their karyotype formula (5 large , 2 medium from submetacentric pair and one large metacentric pair no. 5). The percentage of mitotic index of Baladi genotype (8.28%) was not very much different from that of Chinese (12.08%) whereas it was significantly lower than those of Chinese 30-4 (15.6%),Chinese 31-1(18.18%)and Chinese 31-3 (16. 8%). Means of total chromosomal abnormalities (including anuepliody, break and stickiness) were remarkably lower in genotypes Baladi (7.64%) and Chinese (9.38%)than those of Chinese 30-4 (11.94%), Chinese 31-3 (11.2%). Statistical analysis revealed that there was a high correlation (0.77) between the mitotic index and the percentage of mitotic chromosome abnormalities. Isozymes [Acid phosphatase, Glutamate Oxaloacetate Transaminase (GOT), Peroxidase and Esterase) banding patterns were qualitatively compared. The banding patterns of esterase (2bands) and GOT (one band) were similar in all five genotypes. As for Pyroxidase, the four genotypes of the Chinese origin had two bands, whereas only one band was shown by the genotype Baladi that was similar in molecular weight to small band of Chinese genotypes. All studies genotypes of acid phosphatase showed one band, which was of a low molecular weight in all except in Chinese genotype where it was a high molecular weight and Chinese 31-1 in which both low and high molecular weight bands were found.

Field experiments were conducted to study effect of adding mineral nitrogen as Ammonium nitrate compared with or without two types of organic manuals e.g. Chechen and sheep manuals in presence or absence of inoculums of two strains of Aztobacter vinelandii on the growth and chemical composition of squash plants. Obtained date revealed that all treatment led to significant increase in all growth parameter i.e. plant height, number of level per plant and dry weight.
Chemical analysis also show significant increase in percentage of nitrogen in treated plants compared with control treatment. Also N up take (gm/ plant) was increased in all treatments. Clear variations among different treatments were detected. The highest values in growth permeates or plant chemical composition were obtained when 45 kg of mineral N combined with 7 tons of Chechen manure in presence of Azotobacter isolate T 26. Data also show that Azotobacter isolate T 26 showed more effect on promoting growth compare with isolate T 16. Adding Chechen manure increased all parameters under test compare with sheep manure. Positive correlation between increase mineral nitrogen and growth parameter under test when mineral nitrogen was added alone. On the contrary when mineral nitrogen was compared with any other treatment a clear negative relation between increase the N dose from 45 to 60 and most parameter under test.

Samples of seeds from 29 flax cultivars were used to study the effect of seven-year storage period on isolation frequencies of seedborne fungi. Ten of the cultivars were chosen to study the effect of storage period on seed germination. Storage of flax seed for 6 years had no deleterious effect on seed germination; however, a sharp decrease in viability of seed was observed in the seventh year. Clay cv. showed the lowest germination (8%) in the seventh year. A liner relationship was observed between storage period and germination for cvs. Ottawa 770B, Marshall, and C.I. 2008. Sixteen fungi were isolated from flax seeds over seven years. The isolated fungi were, Alternaria alternata, Stemphylium botryosum, Aspergillus flavus, A. niger, Chaetomium sp., Cladosporium sp., Drechslera sp., Epicoccum sp < em>., Fusarium solani, F. oxysporum, Nigrospora sp., Penicillium sp., Phoma sp., Stemphylium sp., Trichoderma sp., and Verticillium sp. In all years, no single cultivar yielded all the 16 fungi, and the frequency of fungi was affected by storage period. In the present study, linear correlation analysis was used to determine colonization incidence (CI)-colonization severity (CS) relationship of flax seedborne fungi over the seven-year period. The analysis revealed that CI-CS relationship of flax seedborne fungi conformed to the linear model regardless of the storage period within a six-year period-that is, the easily measured incidence values can be used for assessment of CS. A significant correlation between CI and CS was lacking in 2006. CI was less sensitive to storage period compared with CS. Isolation frequencies of some fungi were significantly correlated with seed germination. Most of these correlations were negative, which may indicate the presence of causal relationship between seedborne fungi and seed germination. Data for seed germination and frequencies of fungi, isolated from seeds, were entered into a computerized stepwise multiple regression analysis. Using the predictors supplied by the stepwise regression, seven models were constructed to describe the relationship between seed germination (dependent variable) and frequencies of the isolated fungi (independent variables or predictors). The R2 values of the models ranged from 12.50 to 50.20%, which indicates that seedborne fungi of flax play a minor role in determining variability in seed germination- that is, most of this variability is attributed to the effects of other biotic and abiotic factors.

Four isolates of Fusarium oxysporum f.sp. vasinfectum (FOV) were tested for levels of pathogenicity on 45-day-old greenhouse grown seedlings of 20 cotton genotypes. Isolates differed significantly (p=0.04) in their pathogenicity on the genotypes. Similarly, differences among genotypes were very highly significant (p=0.0000) when they were tested against the isolates. Isolate x genotype interaction was a highly significant (p=0.01) source of variation in wilt incidence suggesting that the genotypes responded differently to the different isolates. These results imply that the pathogenicity of the tested isolates is a mixture of both aggressiveness and virulence and there are significant differences among isolates in both types of pathogenicity. Similarly, resistance of the tested genotypes is also a mixture of both vertical resistance (VR) and horizontal resistance (HR) and the genotypes significantly differ in both types of resistance. Assessment of the relative contribution of each source of variation to the explained (model) variation in wilt incidence revealed that isolate aggressiveness accounted for 0.88% of the explained variation, HR of the genotypes accounted for 89.28%, and virulence of the isolates or VR of the genotypes accounted for 8.95%. The GLC analysis of amino acid composition of cottonseeds revealed the presence of 17 amino acids but the occurrence of each in the seeds varied with the genotype. Lysine and glycine were negatively (r = - 0.385) and positively (r = 0.418) correlated (p < 0.10) with VR of the genotypes to S3 and S4, respectively. None of the other amino acids was significantly correlated with VR of the genotypes to any isolate. Data for VR of the genotypes to each of the tested isolates (dependent variables) and concentrations of the amino acids (independent variables or predictors) were entered into a computerized stepwise multiple regression analysis. Using the predictors supplied by stepwise regression, 4 models were constructed to predict VR of the genotypes to FOV isolates. One of the generated models proved to be effective in prediction VR of the genotypes to S2. This model showed that differences in VR to S2 among the genotypes were due largely to the amino acids alanine, histedine, lysine, and cystine, which accounted for 61.71% of the total variation in VR. Concentrations of proline, histedine, and lysine accounted for 36.36% of the total variation in HR. The findings of the present study suggest that the variations in amino acids may, at least in part, account for the differences in the VR or HR of the different cotton genotypes to FOV.

A total of 16 fungi were isolated from seeds of 29 flax cultivars. The isolated fungi were Alternaria alternata, Stemphylium botryosum, Aspergillus flavus, A. niger, Chaetomium sp., Cladosporium sp., Drechslera sp., Epicoccum sp., Fusarium solani, F. oxysporum, Nigrospora sp., Penicillium sp., Phoma sp., Stemphylium sp., Trichoderma sp., and Verticillium sp. A. alternata, S. botryosum, A. flavus, Cladosporium sp., and Penicillium sp. were the only fungi, which were isolated from all the tested cultivars. Associations among the pairs of isolated fungi were identified and the relative strength of their associations were measured by calculating Pearson correlation coefficient (r) for each pair of the fungi. From 45 to 91 fungal pairings were analyzed each year. Thirty six of the fungal pairs were significantly associated. Of the 36 pairs, 32 were positively associated, and 4 were negatively associated. No significant associations were found in the remainder fungal pairs. Grouping the isolated fungi by cluster analysis, based on their seed colonization patterns, was not related to their taxonomy. Cluster analysis divided the fungi into two distinct groups. One group was consisting of 10 fungi, and a second group was consisting of 6 fungi. Within each group, the fungi were associated strongly and positively, whereas between groups, the fungi were associated weakly or negatively. This result implies the potential existence of cultivar related groups of fungi.

A field experiment was carried out at Giza experimental Station, Agricultural Research Center (ARC), during 2004/2005 and 2005/2006 seasons. The main objective was to study the effect of either iron (Fe) or manganese (Mn) application methods, viz. seed coating at rates of 0.2 g Fe or 0.3 g Mn / 1 kg seed, foliar application at 200 ppm Fe or 300 ppm Mn 45 days after sowing (DAS) and the combination of both methods on growth, yield and seed quality of Giza 40 and Nubaria 1 faba bean cultivars. The split plot design with three replications was used. Results showed that Giza 40 produced significantly taller plants at 64, 85, 106 and 127 DAS. It was also superior in plant shoot dry weight at 64 and 85 DAS. The same trend was true at harvest regarding pod number / plant in both seasons. However, Nubaria 1 surpassed Giza 40 in plant shoot dry weight at 106 and 127 DAS. In addition, Nubaria 1 was superior to Giza 40 in leaf area (LA) / plant at all growth ages, 100-seed weight, seed weight / plant, seed and straw yields / feddan as well as seed crude protein, Fe and Mn contents. All treatments induced significant increases over the control in all investigated yield traits in both seasons. Foliar application of Fe was the most effective treatment in this respect followed by foliar application of Mn. The average increases due to foliar application of Fe were 20.4, 42.8, 14.2 and 23.2 % for number of pods / plant, seed weight / plant, 100-seed weight and seed yield / feddan, respectively compared with control. Results also indicated that foliar application of either Fe or Mn could have improved yield and seed quality traits. The improvement in seed protein, total carbohydrate, Fe and Mn contents due to foliar application over coating or coating + spraying methods were 4.8 and 3.9 % for crude protein, 6.1 and 5.5 % for total carbohydrates, 11.1 and 7.5 % for Fe and 10.4 and 7.2 % for Mn, respectively.

This investigation was conducted for two successive seasons (2006& 2007) to study the effect of training system and fruiting unit length on bud behaviour, growth and productivity of Flame Seedless grapevines. The chosen vines were ten-year-old, grown in a clay loamy soil and irrigated by the drip irrigation system. The vineyard was located at Meniet Samannoud, Dakahlia governorate. Vines were spaced at 2.5 X 3 meters apart, pruned during the second week of February with a load of (40-42 buds/vine) and trellised according to the telephone system. Seventy two uniform vines were chosen. Each four vines acted as a replicate and each three replicates were treated by one of the following treatments: Two training systems were evaluated; the first was cordon training system with three levels of spur length: two, three or four buds per spur, while the second was cane training system with three levels of cane length: six, eight or ten buds per cane.
The results showed that cordon training system gave the best results as compared to cane training system. The spur pruning (2-3 buds/spur) resulted in the highest percentages of bud burst and fruitful buds and coefficient of bud fertility as compared to the cane pruning (6 buds/cane) which recorded the lowest values. In addition, the cordon training system with fruiting unit lengths of 2-3 buds/spur gave the best yield/vine and its components as well as the best physical properties of bunches, improved the physical and chemical characteristics of berries and ensured the best vegetative growth parameters, dynamics of wood ripening, weight of prunings/vine and size of old wood. Total chlorophyll of the leaves and total carbohydrates of the canes were also increased as compared to the cane training system with fruiting unit length of ten buds/cane which gave the lowest values of these parameters.
The economical study indicated that cordon training system with spur pruning for Flame Seedless grapevines gave the highest net income as compared to cane training system with cane pruning.

The present investigation was carried out (Lab. study) in microbial genetics lab., Genetic Dept., Minia University and a field study was carried out at Sakha agriculture research station farm during the two successive summer season of 2004 and 2005.
DNA extract from Bacillus sp < /em>. (grown under 20% NaCl) was used transform salt isolate to sensitive isolates of Azotobacter vinelandii Wild type. The producing transformants were used to infect cultivars of cucumber (hybrid prince) and Okra Eskandrandi).
Results showed that the highest frequencies of transformants (330 x 10-6) was obtained on 10% NaCl at 24 hours.
Results also, indicated that there were significant differences in growth characteristics between the plants inoculated with the tested strains when compared with the control plants (non-inoculated) or the plants inoculated with the wild type strain. All transformants in our study had the best effect on most growth characters and yield as compared with wild type strain.
The best transformants was T-4 which had the highest percentage of increasing total yield with both crops. The data show that there were differences among both, methods of incubation (Liquid or capsules) in their effects on the two crops in their response. The best method was liquid which had the highest values of all growth characters and total yield.
Finally, the present investigation recommends the importance of inoculating vegetables crops with transformants of A. vinelandii to improve their growth and yield with using the liquid method.

This investigation was conducted in the research facilities of the Horticulture Research Institute during the period from 2003 to 2006 to produce and evaluate some tomato hybrids having ripening inhibitor mutant gene rin and study effect of this gene on some quality characters, yield and fruit shelf life. Twenty four tomato cvs. were crossed as female parents with Incridible cv. as male parent. The cultivar Incridible carries rin mutant gene. Parents and F1 populations were planted in RCBD with 4 replicates in two successive summer seasons 2005 and 2006 in open field to evaluate them. It was found that the hybrids Black From Tula Í Incridible and VFNT Í Incridible produced the highest significant early yield (7.7 and 6.85 ton /feddan, respectively). Nine hybrids out of them exhibited significant positive high parent heterosis for early yield ranged from 36.81 to 146.79% with the hybrid Black From Tula Í Incridible having the highest value. The hybrid Strain B Î Incridible produced the highest total yield (17.54 ton/fed.) over all evaluated genotypes; the hybrid Packmore BÍ Incridible exhibited the highest positive high parent heterosis for the same trait. The cultivar Polish produced the highest significant average fruit weight over all evaluated cvs. with mean value 241.4 g. The cultivars Black From Tula, ranked second in this trait having mean value being 205.8g, the two hybrids VFNT Í Incridible and Castle King Í Incridible showed significant positive high parent heterosis. The cultivar Incridible significantly was the highest value among all evaluated genotypes in fruit firmness, fruit firmness during 35 days, and storage ability. All of the evaluated hybrids were not superior in fruit firmness compared to high parent where they showed significant negative high parent heterosis for these traits.

This study was carried out at the laboratory of genetic department and the farm of horticulture department Fac. of Agri. Minia University in two successive seasons on f 2003 and 2004. In this study some transformants of Azotobacter showed high tolerance against saline water (0.25, 0.50, 0.75, 1.oo, 1.25, 1.50, 1.75, and 2.00 g/ 100 ml w/v). Azotobacter transformants were obtained by incubating wild isolate of Azotobacter with an isolate of Bacillus spp., tolerant to 30% NaCl, for 2 or 24 hrs.These resulted transformants were tested in pot experiments under four levels of salinity and presence of squash plants as indicator. The results revealed that:
1- The wild type strain of Azotobacter was sensitive to 1.5-2.0% NaCl as recipient comparison to the Bacillus spp < /em>.which resistant to 30%NaCl as donor.
2- The transformants of Azotobacter were obtained after two hours incubation were less in their frequencies than those were obtained after 24 hours incubation with DNA of Bacillus sp.
3- Adding transformants of Azotobacter to salinity soil led to reduction in the symptoms of salinity on squash plants.
4- Different transformants varied in their effects, regards, plant growth characters under salinity conditions and T2 & T4 showed the best effect.

Two field experiments were carried out during winter season of 2005-2006 and 2006-2007, in EL- Kassasien Horticulture Research Station, Ismailia Governorate. It aimed to study the effect of three irrigation water quantities (800, 1000 and 1200 m3/fed.) combined with three sowing dates (20th Sep.,10th Oct. and 1st Nov.) on two cultivars (Victory freezer and Lincoln) of pea (Pisum sativum L.) grown under sandy soil condition using drip irrigation system. The result indicated that increasing water quantity up to 1200 m3/fed. led to a significant increase of plant growth (plant height, number of branches , leaves per plant and dry weight ) and yield and its components (number of seeds per pod, weight of 100 seeds, net ratio and Green pod yield per fed.).Sowing pea plants on 10th Oct gave the highest value of plant height, number of branches and leaves per plant, dry weight of branches and leaves per plant and yield and its components. Victory freezer cultivar recorded the highest value of plant height, number of branches and leaves per plant, dry weight of branches and leaves per plant and yield and it components. Sowing Victory freezer cultivar on10th Oct. with application of 1200 m3/fed.was the best interaction treatment for increasing plant height, number of branches and leaves per plant, dry weight of branches and leaves per plant and yield and its components.

This study was carried out at the experimental nursery of Horticultural Research Institute; AgriculturalResearchCenter, Giza, during the two successive seasons of 2005 and 2006. The main objective was to study thepossibility of using biofertilization (Rhizobacterein and Phosphorein) to reduce the need for mineral fertilizers and study its effect on the vegetative growth, flowering and chemical composition of Helianthus annuus L. (Big Smile) plants. The results indicated that using a combination of Rhizobacterein and Phosphorein promoted plant height, leaf area and total carbohydrates, compared to using each biofertilizers alone or in combination with half the full rate of chemical fertilization (full rate= 10 g Christalon/plant). Using half the amount of chemical fertilizers and replacing the other half by the combination of biofertilizers caused an increase in number of leaves, fresh and dry weights, and the leaves contained much more total chlorophylls and potassium. This treatment also caused a significant increase in number of lateral flowers. It could be concluded that treating sunflower (Big Smile) plants with 5 g Rhizobacterein and 10 g Phosphorein plus 5 g Christalon per plant produced the most vigorous vegetative growth and the largest number of lateral flowers with good characteristics.

Two field experiments were conducted to test the efficiency of selected rhizobia in charcoal and filter-mud as suitable carriers. Rhizobium isolates procured from naturally initiated nodules were compared with imported strains for nodulation in two forage plants, Medicago sativa and Clitoria ternateaa at two different sites in the Sudan. The local isolates proved to be as efficient as the imported strains. In the field experiment, there was a marked positive effect in response to inoculation with the carrier based inoculants. Fresh and dry weight, total nitrogen content and number of nodules per plant were significantly higher in modulated plants as compared with the control (non-inoculated and non-inoculated plants which received urea. The range of increase was between 16 and 94%.

Two field experiments were conducted at the Experimental Farm of Horticultural Research Institute (Qaha Farm) during the two successive winter seasons of 2005 and 2006 to elucidate the effect of some soil amendments application such as farmyard manure at 20m3/fed, in addition gypsum at 2 ton/fed, sulphur at 500 kg/fed and their combination besides to the check treatment on vegetative growth, heavy metal uptake (lead and cadmium) by edible parts of lettuce plants (Lactuca sativa L) "cv dark green" and radish (Raphanus sativus L.) "cv white radish" which grown near the Cairo – Alexandria Agriculture road. Traffic densities on the examined road were about 120960 vehicles/day.
The obtained results show that applying farmyard manure, gypsum and/or sulphur reflected the highest values of vegetative growth parameters expressed as fresh and dry weight per plant as well as number of leaves /plant with high significant differences compared with the control treatment (without application). Using soil amendments especially in a mixture form exhibited the highest values of vegetative growth aspects and total yield as well as ascorbic acid content. Heavy metal uptake by edible parts were depressed with the addition of single or mixer application of farmyard manure and gypsum compared with sulphur treatment and the control.
Generally, farmyard manure and gypsum in a single or mixer application gave the best results and are recommended for increasing productivity and improving the quality of lettuce and radish grown near the high densities traffic roads by reduction the heavy metal contents
