Fungal disease i.e.,chocolate spot (<em>Botrytis fabae</em> Sard.)and rust (<em>Uromyces vicia fabae</em> (Pers.) Schart) are the most destructive diseases of faba bean and causes considerable dramatic damage losses on faba bean yield worldwide Therefore, the use of plant nutrients (leaves fertilizers) i.e., Ascobein(As), Citreen(Ci) and Potassen (Po) to both diseases (chocolate spot and rust) in<em> Vicia fabae</em> ,gave evidence for controlling these diseases. Results showed that ,spraying faba bean plants with As+Ci+Po significantly decreased chocolate spot disease with 3.5% and 3.81% while ,rust was by decreased 5.2% and 5.77% for the two growing seasons 2010/2011 and 2011/2012.
Total chlorophyll reached to the maximum values when using Potassen (1.933mg/g f.w.) while ,As+Ci+Po as combination revealed the most superior effect on total phenolics compounds .All treatments were found to be most effective in increasing growth characters and yield of faba bean.

Two field experiments were carried out at the Experimental Farm of Gemmeiza Agriculture Research Station, Agricultural Research Center, Egypt, during the two growing summer seasons of 2010 and 2011. The main objective of this study was to evaluate the effect of compost rates, humic acid treatments and nitrogen fertilizer rates on growth, grain yieldand its components of maize cultivar yellow single cross 166. Each rate of compost was performed in separate experiment. Every experiment of compost rates was carried out in split plot design with four replications. The main plots were occupied with humic acid treatments. The sub-plots were assigned to nitrogen fertilizer rates. The obvious results of this investigation can be summarized as follows:
Adding 30 m<sup>3</sup> compost/fed recorded the highest values of growth traits, grain yield and its attributes in both seasons and their combined. Moreover, applying 15 m<sup>3</sup> compost/fed came in the second rank in both seasons and their combined. The lowest values of these characters were obtained by control treatment (without compost) in both seasons and their combined
Soaking seeds before planting in humic acid plus foliar spraying plants with humic acid enhanced maize growth, subsequently produced the highest means grain yield and its attributes in both seasons and their combined. It was followed by soaking seeds before planting in humic acid or foliar spraying plants with humic acid in both seasons and their combined.
There were substantial differences in all studied characters among various studied nitrogen fertilizer rates inboth seasons and their combined. Fertilizing maize plants with 120 kg N/fed produced the highest values of these characters inboth seasons and their combined. However, using 60 kg N/fed was accompanied with the least values of grain yield and its attributes characters inboth seasons and their combined, as well as there are many significant effect of the interactions among studied factors on studied characters.
Generally, it can be concluded that organic fertilizing maize plants hybrid S.C. 166 with 30 m3 compost/fed and soaking seeds plus foliar spraying plants with humic acid at the rate of 1000 ppm in addition mineral fertilizing with 120 or 90 kg N/fed in order to maximizing its growth and productivity under the environmental conditions of Gemmeiza district, El-Gharbia Governorate.

The successful establishment of crop mainly depends on good quality seed which germinate rapidly, uniformly and able to withstand under environmental adversity after sowing. Laboratory experiment was conducted at Seed Technology Unit, Mansoura, Egypt to evaluate the effect of rice seed priming (c.v. Giza 177) with CaCl<sub>2</sub> at osmotic potentials (- 0.75, -1.00 , -1.25 , -1.50 MPa and distilled water) for 6 , 12, 24 , 36 and 48 hours on seed germination, seed and seedling vigor under normal and salinity stress. The obtainedresults of this study indicated that salinity levels (9 dS/m) delayed germination, seed and seedling vigor characters compared with normal salinity (0.3 dS/m). Rice seed priming with CaCl<sub>2 </sub>at (-1.00 MPa) followed by (-1.25 MPa) gave the highest values of germination percentage, speed of germination index, germination rate, germination co-efficient, germination energy %,seedlings length, seedlings dry weight, water uptake % and decreasing mean germination time as well as time to 50 % germination compared with control (distilled water) under salinity stress. Whereas, priming seed with distilled water (control) resulted in the lowest germination characters under salinity stress. Priming duration 24 h showed its superiority in improving germination characters comparing with other priming durations. It could be concluded that, priming rice seed (c.v. Giza 177) with osmotic potential (-1.00 MPa) for 24 h can reduce the injurious effects of salinity stress.

Two field experiments were carried out at Sakha Agric. Res. Station, Kafr El-Sheikh Governorate, Egypt during 2010/2011 and 2011/2012 seasons, to study the effect of three irrigation water quantity (3000, 2500 and 2000m<sup>3</sup>), four nitrogen sources (Urea 46.5% N, Ammonium sulfate 20.6% N, Ammonium nitrate 33.5% N and Anhydrous ammonia 82% N) and three nitrogen rates (70, 80 and 90kg N/fed.) on growth yield and quality of sugar beet c.v.Gloriuf . The experiments were laid out in split plot design with four replications.
The obtained results indicated that decreasing amount of irrigation water from 3000m<sup>3</sup> to 2500 and 2000m<sup>3</sup> caused reduction in root fresh weight, α amino nitrogen and potassium% .On the other hand, reducing irrigation level from 3000m<sup>3</sup> to 2500 and 2000m<sup>3</sup> increased root length , sodium percentage as well as purity percentage .
Sugar beet plants received anhydrous ammonia gave the highest values of root length, root fresh weight , potassium and purity percentage , on the other hand, it gave the lowest values of α amino nitrogen and Sodium percentage.
Sugar beet plants fertilized with nitrogen fertilizer at the rate of 90kg N/fed. gave the highest values of root length , root fresh weight , potassium percentage and α amino nitrogen percentage, while the highest values of sodium percentage and purity percentage were recorded with plants received nitrogen fertilizer at the rate of 70kg N/fed. as compared with other nitrogen fertilizer rates .
At all irrigation levels nitrogen fertilizer application in the form of anhydrous ammonia gave the highest values of root length, root fresh weight, potassium% and purity%, but it gave the lowest values of α amino nitrogen% and sodium percentage .At the highest water regime (2000m<sup>3</sup>/fed.) raising nitrogen fertilizer from 70 to 90kg N/fed. increased root length , root fresh weight , α amino nitrogen% and potassium% , on the contrary the highest Na and purity% were found with 70kg N/fed. At all nitrogen fertilizer rates plants received nitrogen in the form of anhydrous ammonia gave the highest values of root length, root fresh weight and purity%, on the other hand, this treatment gave the lowest values of α amino nitrogen % percentage and sodium percentage .
At the highest water regime (2000m<sup>3</sup>/fed.) plants fertilized by nitrogen fertilizer at the rate of 90kg N/fed. in the form of anhydrous ammonia gave the longest root , heaviest roots, potassium percentage and purity percentage, on the contrary it gave the lowest α amino nitrogen percentage ,sodium percentage.
Generally, it could be concluded that when the shortage of irrigation water was presented, fertilizing sugar beet plants with nitrogen fertilizer in the form of anhydrous ammonia at the rate of 90kg N/fed. improved growth and root juice quality of sugar beet plants at Sakha Kafr El-Sheikh Governorate conditions.

The present study was carried out at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, Dakahlya Governorate, during the two successive seasons of 2011 and 2012 to determine general, specific combining abilities and heterosis for grain yield and yield associated traits by crossing 6 inbred lines of maize in a half diallel mating design. Fifteen F<sub>1</sub> single crosses with their parents were planted in a randomized complete block design with three replicates.
Results showed that mean squares of crosses were significant for all studied traits i.e. number of days to 50% tasseling and silking, plant height, number of rows/ear, number of grains/row, 100-grain weight, grain yield/plant and shelling percentage. The analysis of variance revealed highly significant mean squares of general combining ability (GCA) and specific combing ability (SCA) for all studied traits, indicating the importance of both additive and non additive genetic effects for these traits. GCA/SCA variances ratios were found to be greater than unity for number of days to 50% tasseling and silking, plant height and 100-grain weight, indicating that the additive and additive×additive types of gene action were greater importance in the inheritance of these 4 traits. Best GCA effects for earliness traits (number of days to 50% tasseling and silking) achieved inbred lines P4 (Inb.173) and P5 (Inb.174), for plant height were P1 (Sd63), P3 (Inb.19), P4 (Inb.173) and P5 (Inb.174), for number of rows/ear were P1 (Sd63), P3 (Inb.19) and P4 (Inb.173), for 100-grain weight was P1 (Sd63). Inbred lines P1 (Sd63) and P2 (Sd7) showed best GCA effects for grain yield. Also P2 (Sd7) and P6 (Inb.170) showed best GCA effects for shelling percentage.
Hybrid combinations P2×P5 and P3×P6 showed largest SCA effects for number of days to 50% tasseling, for number of days to 50% silking were P1×P2, P1×P6, P2×P5 and P3×P4, for plant height were P1×P3, P1×P5, P2×P3, P2×P6, P4×P5 and P4×P6, for number of rows/ear were P1×P2, P1×P4, P2×P3, P3×P4, P4×P5 and P5×P6 and for shelling percentage were P1×P3, P1×P4, P2×P3, P2×P4, P3×P4 and P5×P6. Concerning number of grains/row, grain yield/plant and100-grain weight, most of crosses recorded positive significant or highly significant SCA effects. Results showed significant or highly significant heterosis for all studied traits. Cross P3×P6 was the best, with highly significant negative heterosis over mid and better parents for number of days to 50% tasseling. Cross P2×P3 recorded the highest negative heterosis over mid and better parents for number of days to 50% silking. Regarding to plant height, none of the cross combinations showed negative heterosis over mid and better parents. The best cross over mid and better parents for number of grains/row, grain yield and 100-grain weight was P1×P2. Crosses P1×P4 and P5×P6 recorded the highest positive heterosis over mid and better parents for number of rows/ear and shelling percentage, respectively.
Therefore, it could be stated that parents with good positive GCA for grain yield (P1 and P2), negative GCA for tasseling, silking date (P4 and P5) and dwarf plant height (P1, P3, P4 and P5) may be extensively used in hybridization program as a donor. The better performing four crosses (P1×P2, P1×P4, P1×P6 and P2×P3) can be utilized for developing high yielding hybrid varieties as well as for exploiting hybrid vigor.

Two field experiments were carried out at the Experimental Farm of Sakha Agricultural Research Station, Agricultural Research CenterEgypt, during the two successive summer seasons of 2011 and 2012. The main objectives of this study were to determine the effect of tillage treatments, plant distribution patterns and sources of nitrogen fertilizer on growth, yield and its components of corn hybrid S.C. 128. Each tillage treatment was performed in separate experiment. Every experiment of tillage treatment was carried out in split plot design with four replications. The main plots were occupied with plant distribution patterns. The sub-plots were assigned to sources of nitrogen fertilizer. The most important results could be summarized as follaws:
All studied characters were significantly affected by different studied tillage treatments in the two seasons. Using chisel plow twice gave the highest values of studied characters in both seasons. Using chisel plow once in addition to Stiller plow once was accompanied with the least values of these characters in both seasons.
There was significant effect on all studied characters due to plant distribution patterns in the two seasons. Planting maize in ridges 80 cm apart, 22 cm between hills and one plant per hill produced the highest values of all studied characters in both seasons. Planting corn or maize in ridges 70 cm apart, 50 cm between hills and two plants per hill gave the lowest values of these characters in both seasons.
Sources of nitrogen fertilizer had a significant effect on all studied characters in the two seasons. Using Urea fertilizer resulted in the highest means of all studied characters followed by using Ammonium Nitrate then Ammonium Sulphate fertilizers in both seasons.
It can be concluded that tillage corn soil by using chisel plow twice and planting in ridges 80 cm apart, 22 cm between hills and one plant per hill in addition using Urea as a source of nitrogen fertilizer in order to maximize corn hybrid S.C.128 growth and its productivity under the environmental conditions of Sakha district,Kafr El-Shikh Governorate Egypt.

Two field experiments were conducted at Rice Research and Training Center ( RRTC ) Farm, Kafr-El-Sheikh Governorate, Egypt, during two successive seasons of 2009 and 2010. The main objectives of this study are; identifying both the optimum seeding rates and hill spacing to increase the yield of hybrid rice seed for the hybrid IR69625A/Giza181R (2046H), this study included, three seeding rates for cytoplasmic male sterile line (6kg/fed, 8kg/fed and 10kg/fed) and three hill spacing ( 15×10, 15×15 and 15× 20cm).The treatments were arranged in split plot design with three replications, where seeding rates distributed as main plots while hill spacing were allocated in the sub plots. Data were recorded on different traits relating to yield and its components .
The results showed that, the seed rates had highest significant on plant height , panicle weight, panicle length, panicle exsertion, no. of spikelets/ panicle seed set, 1000 grain weight and grain yield . The optimum treatment to produce high quantity of hybrid rice seed from the hybrid combination of IR69625A/Giza181R (SK.2046H) was 8kg seeds/fed, for the seeding rate.
Moreover, hill spacing treatments had highest significant on all studied characters,except no. of panicles/m<sup>2 </sup>character. The best hill spacing for cytoplamic male sterile was 15 x 15cm.
The interaction between seed rates and hill spacing was significant for all studied characters.
It could be concluded that the optimum treatments to produce high quantity of hybrid seed from the hybrid combination IR69625A/Giza 181R (SK.2046H) was 8kg seeds/fed for the seeding rate and (15×15cm) for hill spacing, because this treatment was recorded the highest values of panicle exsertion (81.61%),seed set (46.06%) and grain yield (1.32 t/fed).

A field experiment was conducted at El-Kanater Horticultural Research Station in the seasons of 2010 and 2011 to study the effect of three soil moisture levels (25, 50 and 75 % depletion i.e. wet, medium and dry) and three application of potassium unit i.e., 500, 1000 and 1500 g/tree. The obtained results indicated that water consumptive use (W.C.U.) ranged between 1255.5 and 934.4 mm in the first season from 1278.6 to 974.63 mm in the second one, corresponding to 5273.1 and 3924.5 m<sup>3</sup>/fed. in the first season and 5370.1 to 4093.4 m<sup>3</sup>/fed. in the second season, respectively. Increase of potassium application slightly decreased the water consumptive use (W.C.U.).
Monthly water use was low after dormancy, then increased to reach a maximum during July and August. The rates declined to reach minimum during October. Seasonal crop coefficient (Kc) was 0.79. The wet moisture stress level (75 % available water) increased all studied growth characters in the two successive seasons. The water use efficiency was 0.96 and 1.0 kg fruits/m<sup>3</sup> water consumed. It was markedly increased with increased potassium application.
Increasing soil moisture enhanced leaf area, fruit length, fruit weight, fruit size, while decreased total soluble solids, T.S.S./acid ratio and acidity. The wet moisture stress level (75 % available water) gave the higher yield.

Two field experiments were carried out during winter seasons of 2010 - 2011 and 2011-2012, at theExperimental Farm of El Kassasein Horticultural Research Station, Ismailia Governorate, Egypt, to study the effect of NPK levels (25, 50 and 100 % of recommended dose), foliar applications (Control, HA, EM and HA+ EM) and magnetite levels (without and 150 kg/fed.) on growth, yield and its components of pea plants (<em>Pisum sativum </em>L.) cv. Master B under sandy soil conditions.
Results indicated that increasing NPK fertilizer levels up to 100% recommended dose cause a significant increases in plant growth (plant height, number of branches and leaves/plant and dry weight/plant ) and yield and its components (pod length, number of seeds/pod, weight of 100 seeds and green pods yield/fed).
Spraying pea plants with a mixture of HA+ EM gave the highest values of vegetative growth parameters and yield and its components. In the same trends, treated plants with magnetite recorded the highest values of vegetative growth and yield and its components as compared to untreated plants.
application of 50% NPK and spraying plants with humic acid + EM plus magnetite at 150 kg/fed recorded higher values of plant growth and green pod yield per feddan as compared to 100% NPK alone (control) without significant difference between both treatments. Fertilizing pea plants with 100% NPK and spraying plants with combination of humic acid + EM with application of 150 kg/fed magnetite gave the highest values of plant growth parameters, yield and its components as compared to other interaction treatments.

Two field experiments were carried out at Sakha Research Station, Kafr El–Sheikh Governorate during two growing seasons of 2010/2011 and 2011/2012 to study the effect of the combinations between foliar application of three Fe levels (0, 1 , and 2g/L as Fe- EDTA), three Mn levels (0, 0.5 and 1 g/L as Mn-EDTA) and two sulpher levels (0 and 8 cm S/L as calcium poly sulphide 30 %) on yield and quality of sugar beet.
<strong>The obtained results proved that: </strong>
The increase of Fe level up to 2 g / L, Mn up to 1g/L and 8 cm S/L individually as foliar application significantly increased root length and diameter as well as sucrose%, extractable sugar %, purity % , yields of top, root and sugar (ton / fed), whereas Juice impurities content (K, Na and-amino N) and sugar losses to molasses were decreased in both seasons.
Foliar spray beet plants at the rate of 2g Fe/L+1g Mn / L+8 cm S/L achieved the highest root yield (29.32 and 33.82) in the 1<sup>st</sup> and 2<sup>nd</sup> seasons, respectively.
Therefore, it could be recommended that, spraying beet plants by 2g Fe / L +1g Mn / L + 8 cm S/L as foliar application to maximize root yield.

Low levels of available nitrogen in soils may limit rice growth. An investigation was undertaken at the farm of Rice Research and Training Center, Sakha, Kafr El-Shiekh during 2010 and 2011 rice growing seasons the objectives of this investigation was aimed to evaluate the effect of different nitrogen sources combination on growth, yield and its components of Egyptian hybrid rice 1 (EHR1). All growth traits i.e. plant height, number of tillers hill<sup>-1</sup>, chlorophyll content as well as dry matter accumulation differed significantly by N sources combination. Application of 46 kg N fed<sup>-1</sup> plus 7 tons of FYM fed<sup>-1</sup> recorded highest values of these traits at all different growth stages, while the untreated control treatment gave the lowest ones. Applications of 46 kg N fed<sup>-1</sup> plus 7 tons FYM fed<sup>-1</sup> produced tallest panicles and highest panicle grain weight, number of panicles hill<sup>-1</sup>. The untreated (control) treatment gave the minimum values of all traits mentioned above.
