Two field experiments had conducted in of 2012 and 2013 summer seasons at Deir Mawas, Menia Governorate, Egypt to study the effect of irrigation amounts applied with center- pivot sprinklers and fertilization on yield and quality of soybean. The results indicated that application of 2880 m3 /feddan (4200 m2) significantly surpassed application of 2240 and 1600 m3 /feddan in plant height, number of pods and seeds/plant, seed index and seed yield/plant. The highest seed yield/fed. was obtained with irrigation by 2880 m3 /fed., which was 52.2 % higher than irrigation with 1600 m3 /fed. (0.620 ton/fed.). The maximum oil content (20.74 %) and protein content (41.79) had achieved with irrigating by 2240 m3/feddan. However, the highest yields of oil (266.52 kg/fed) and protein (534.88 kg/feddan) had obtained from irrigation by 2880 m3 water/feddan.
The highest soybean plant height, number of pods and seeds/plant, seed index and seed yield/plant were obtained with addition of NPK compound (19:19:19) with15 units of each elements (F2). In addition, F2 fertilizer treatment recorded the highest values of seed, oil and protein yields/feddan and IWUE. On the other hand, application of NPK compound (19:19:19) with 7.5 Kg of each element/feddan(F4) produced the highest oil and protein contents in seeds (21.28 and 43.06 %, respectively). The interactions between the amounts of irrigation and fertilizer treatments revealed highly significant differences in plant height, number of seeds/plant, seed index, seed yields per plant and feddan, oil and protein contents and yields. Irrigation by 2880 m3 /feddan with addition NPK compound (19:19:19) with 15 Kg of each element/ feddan significantly gave the greatest values of plant height, seeds/plant, seed index, seed yield/plant and yields/feddan of seed, oil and protein.

Two field experiments were conducted at El-Hamoul area, Kafr El-Sheikh Governorate, Egypt during 2010/2011 and 2011/2012 seasons, to study the effect of six biofertilization treatments (Without biofertilization (control),inoculation wheat seeds with Nitrobine (450 g/feddan) 100% of the recommended dose , Nitrobine (675 g/feddan) 150% from the recommended dose, Cerialine (450 g/feddan) recommended dose and Cerialine (675 g/feddan) 150% from recommended dose) and four nitrogen rates (0, 30, 50 and 70kg N/feddan.) and their interactions on growth, yield and quality of wheat .
-The obtained results indicated that plants produced from seeds inoculated with nitrobine at the rate of 150% from the recommended dose gave the highest number of spikes/m2, 1000 grains weight, grain yield/feddan, straw yield/feddan., carbohydrate % and protein% in grains in both seasons.
- Application of nitrogen fertilizer at the rate of 70 kg N/feddan surpassed all the other treatments in all measured parameters in both seasons.
- The interaction effect between biofertilizers and chemical nitrogen fertilizer rates was significant on all studied characters in both seasons. Wheat plants produced from grains inoculated by nitrobine at the rate of 150% and received nitrogen fertilizer at that rate of 70 kg N/feddan gave the highest values of studied traits in both seasons. Treatment having nitrobine at the rate of 150%

Two field experiments were carried out at a Farm in El-Shahyna Village Kafrelsheikh Governorate (North Delta), Egypt, during the two successive winter seasons of 2012 and 2013 to study the effect of starter solutions of NPK fertilizers in soil and foliar application of some stimulants (amino acids and seaweed extract) as well as their interactions on growth and yield of Chinese cabbage plants (Brassica rapa L. subsp. pekinensis) cv. (Manoko). Four starter fertilizers treatments included three sources of N, i.e., ammonium sulfate (20.5 % N), ammonium nitrate (33.5 %) and urea (46%) as well as without starter solution and two sources of stimulants. The experiments were carried out in a split-plot with three replications.The results indicated that, starter solutions treatments resulted in highly significant increases in stem length, stem diameter, whole stem weight, number of total leaves/ plant and fresh weights of outer leaves (inedible), inner leaves (edible) , total leaves / plant and weights of total yield (whole head) and marketable yield (edible head) compared with the control treatment (without starter solution) in both seasons. The increase (%) in weights of total and marketable yield resulted from using starter solution No. 1 (containing Ammonium Sulfate), No. 2 (containing ammonium nitrate) and No. 3 (containing urea) over the control( without starter solution) were (51.8 and 67.6(%) , 59.1 and 75.6(%) , 55.7 and 75.6(%) (as av. two seasons), respectively.Amino acid and seaweed extract treatments caused highly significant increases in stem diameter, whole stem weight, number of total leaves/ plant, weights of outer leaves (inedible), inner leaves (edible) and total leaves/ plant , fresh weights of total yield (whole head) and marketable yield (edible head) compared to the control (unsprayed) treatment in both seasons. Such increases were highly significant in the first season for leaf area / plant and leaf area index (LAI) . Moreover, they had a significant increase in stem length in both seasons such increase were significant in the second one for leaf area /plant and leaf area index(LAI). The increase (%) in weights of total and marketable yield resulted from foliar spray with amino acid and seaweed extract over no spray were 43.3 and 43.0(%), 14.8 and 14.3(%) (as av. two seasons), respectively. The highest values of previous characteristics were recorded when Chinese cabbage plants sprayed with amino acid followed by seaweed extract compared with unsprayed plants which had the lowest values in both seasons.The combined interaction between starter solutions and foliar spray with some stimulants had no significant effect on stem characteristics, leaves characteristics and weights of total and marketable yield in both seasons.

Six rice genotypes with different drought tolerance were crossed. Six populations (P1, P2, F1, F2, BC1 and BC2) of three rice crosses namely Giza 177 x Giza 178 (cross I); Sakha 103 x WAB 880 SG 33 (cross II) and Sakha 104 x IET 1444 (cross III) were raised in a randomized complete block design with three replications during the three successive summer seasons from 2010 to 2012 at the Farm of Rice Research and Training Center Sakha, Kafer El-Sheikh, Egypt. This study aimed to determine the heterosis, gene action, heritability, genetic advance and phenotypic correlation response to selection and prediction by the new lines for the traits of days to 50 % heading, plant height, panicle length, number of panicles/ plant, number of filled grains/ panicle, 100-grain weight, sterility % and grain yield/ plant. Flashing water irrigation was added every 10 days intervals.
The results obtained from the mean of parents, F1 and F2 generations showed wide range in mean values between the parents and the presence of partial and over-dominance were found for all studied characters. Significant and highly significant positive estimates as a deviation from mid and better parents in all crosses for panicle length, number of panicles/ plant and grain yield/ plant, also highly significant positive estimates as a deviation from mid and better parents in the first two crosses for plant height. Scaling test provide evidence of non-allelic interaction in controlling all the characters studied in most crosses, the additive gene effect (d) was more important in the genetic system for all studied characters, dominance gene effects (h) and additive x additive gene effects (i) were played an important role in the inheritance of plant height, panicle length, number of filled grains/ panicle, 100-grain weight, sterility % and grain yield/ plant. The additive x dominance (j) were significant and involved in the inheritance of days to 50 % heading, plant height, number of panicles/ plant, number of filled grains/ panicle, 100-grain weight, sterility % and grain yield/ plant. However, the dominance x dominance (l) were involved in the genetic control of all characters. Heritability estimates in broad sense were high. Meanwhile, heritability estimates in narrow sense were mostly low. The maximum genetic advance of the mean values was found to be high for number of panicles/ plant, plant height and days to 50 % heading characters. Highly significant and positive correlation was found for grain yield/ plant with panicle length, number of panicles/ plant, number of filled grains/ panicle and 100-grain weight in all studied crosses.
From the foregoing results, cross II (Sakha 103 x WAB 880 SG 33) and cross III (Sakha 104 x IET1444) could be recommended for growing under water deficiency to obtain the highest rice grain yield and the highest values of saving water at the same time.

Two pot experiments were carried out during two growing seasons (2010/2011 and 2011/2012) at Seed Technology Research Unit, Seed Technology Research Department , Field Crops Research Institute. The aim of these experiments were to study the response of faba bean namely (Sakha1) growing in saline soil (2000 mg/L, 4000 mg/L, 6000 mg/L and 8000 mg/L) to application of some growth promoters (Salicylic acid 250 mg/L, Ascorbic acid 250 mg/L, α –Tocopherol 100 mg/L, Humic acid 1000 mg/L, Yeast extracts 2000 mg/L) as seed soaking, foliar spraying or seed soaking and foliar spraying together. The effect of these promoters on faba bean yield and it`s components were recorded. Results indicated that salinity stress levels at 8000 mg/L followed by 6000 mg/L, 4000 mg/L and 2000 mg/L respectively, compared with control treatment (320 mg/L) were the most effective in decreasing all yield and it`s parameters (number of pods / plant, pods weight / plant (g), number of seeds / plant, seeds weight / plant (g) and 100- seed weight (g)). While, applied antioxidants promoters ASA 250 mg/L followed by SA 250 mg/L, Yeast extract 2000 mg/L, Humic acid 1000 mg/L and Tocopherol 100 mg/L compared with water as control applied as (seed soaking, foliar spraying or seed soaking and foliar spraying together) were the most effective in increasing all yield and it`s parameters. It could be seen that applied antioxidants as growth promoters hardly decreasing the harmful effects of salinity stress on yield and it`s components of faba bean plants.

In order to study the effect of nitrogen and potassium on yield and yield components on four bread wheat cultivars; Gemmiza 11, Sids 12, Sids 13 and Shandaweel 1, the treatments included three levels of nitrogen: 50, 75 and 100 kg N/fad accompanied by tow levels of potassium: 24 and 48 kg Ko2/fed. Field experiment was conducted at Sakha Agricultural Research Station, Agricultural Research Center, during the two growing seasons of 2008 - 2009 and 2009-2010. The treatments were arranged in a spilt-spilt plot design with four replications. The main plots were devoted to nitrogen levels and the sub-plots were allocated to potassium levels, while the sub-sub plots were designed to cultivars.
Increasing nitrogen levels up to 100 kg N/fad. Resulted in significant gradual increase in days to heading and maturity, plant height, number of spikes/m2, number of kernels/spike, and grain yield/fad.
On the hand, there was no significant effect for potassium fertilization levels on the tested agronomic characters.
The results indicated that Gemmiza 11 was the earliest in heading and maturity in the two seasons. Shandaweel 1 gave the highest grain yield/fed in the first season while it was the latest one in days to maturity.Sids12 cultivars gave more spikes/m2in the both seasons.While,Sids 13cultivars gave the highest values of 1000-grain weight.
The interaction between nitrogen and potassium, nitrogen and cultivars, potassium and cultivars and cultivars, nitrogen and potassium
rates did not show any significant effect on grain, straw yield/fed and harvest index in the two seasons. However, the interaction between nitrogen rates and cultivars and potassium and cultivars was significant for number grains/spike in the two seasons. The interaction between nitrogen levels and cultivars was significant for no. of spikes/m2 in the second season. Also, the interaction between nitrogen and potassium levels was significant for no. of spikes/m2 in the first season.
It could be concluded that Shandaweel 1 can be cultivated under fertilization at 100kgN/fed to produce the highest yields of grains and straw per Fadden.

Studying green areas in Mansoura city as a model of Egyptian cities has become a very important issue. Therefore, the purpose of this study is to identify the green areas in the city of Mansoura and its adequacy range of quantity and quality and propose appropriate solutions. We have studied the green areas in the city as following: the total area of the public green areas, the rates of green areas in the city (the per capita green area in the city in 1949, 1977, 2007 and 2012- the international norms of green spaces), the distribution of green areas, the last green area changes in Mansoura city from 2007 to 2013(Lost green areas – Al Geash st developments - Shagret El-dorr garden) the types of green areas in the city, the maintenance (the available gardening tools in East and West district of Mansoura city in (2010) - The Green areas expenses during fiscal year (2009/2010) in Mansoura city) and street trees (a field survey for street trees in 22 of Mansoura city main and secondary streets). We have found that the status of green spaces in the city is very poor for a lot of things, the per capita green area is 0.4055 m2 in 2012 from 0.50 m2 in 2007 due to the increasing population and the decreasing of the total green areas, the distribution (the green areas of the city didn’t make a network permeating the body of the city - no connection between its units - its small areas did not allow doing many activities…), maintenance (a shortage in tools necessary for maintenance – the total expenses on green areas during fiscal year (2009/2010) in Mansoura city was about 0.4172 EGP/m2),street trees (the rule of a one type of trees Ficus retusa - …). To improve the green areas in Mansoura city we have proposed: steps are now available, developments of a short-term plan, development of a long-term plan and adding green areas.

Combining ability is an important genetic attributes to cotton breeders in anticipated improvement via hybridization and selection. Seven parents were involved in a half diallel mating design which was analyzed by GGE biplot graphical method. General combining ability (GCA) and specific combining ability (SCA) effects were significant for all traits. None of the parents were found to be a good combiner for all traits where the parents Giza 75 x Sea, 10229 x Giza 86 and Giza 86 observed general combining ability for seed cotton yield, lint cotton yield and boll weight, respectively. The crosses Giza 92 x (Giza 75 x Sea) and Giza 92 x Giza 93 revealed specific combining ability for seed cotton yield, meanwhile, the cross , Giza 85 x Giza 93 for lint cotton yield and also, and the cross (Giza 75 x Sea) x (10229 x Giza 86) for boll weight.
The graphical demonstration proposed by the biplot analysis provided an effective overview of GCA and SCA effects and mean performances in crosses, where the analysis showed that the parents Giza 75 x Sea, 10229 x Giza 86 and Giza 86 could be used in improvement of plant breeding program.
In addition, the biplot also provided an opportunity for assessing the interrelationship among the genotypes.

Two field experiments were conducted at the Experimental Research Station in El-Serw, AgriculturalResearchCenter during 2010/2011 and 2011/2012 seasons to study the effect of nitrogen and compost combination treatments and potassium fertilizer levels on growth, yield and its components as well as grain quality of some wheat cultivars. The experiments were carried out in a strip-split plot design with three replicates. The vertical plots were assigned to wheat cultivars (Sakha 93, Gemmiza 9 and Gemmiza 10). The Horizontal plots were devoted to nitrogen and compost combination treatments as follows: 1) 100 % mineral nitrogen (90 kg/fed). 2) 75 % mineral nitrogen (67.5 kg/fed) + 25 % organic nitrogen "compost" (22.5 kg/fed). 3) 50 % mineral nitrogen (45.0 kg/fed) + 50 % organic nitrogen "compost" (45.0 kg/fed). 4) 25 % mineral nitrogen (22.5 kg/fed) + 75 % organic nitrogen "compost" (67.5 kg/fed). 5) 100 % organic nitrogen "compost" (90 kg/fed). While, the sub – plots were allocated to potassium fertilizer levels (0 and 48 kg K2O/fed).
Results showed that Gemmiza 10 cultivar surpassed other studied cultivars in number of days to heading, flag leaf area, plant height, number of spikes/m2, number of spikelets/spike, number of grains/spike, grains weight/spike, grain and straw yields/fed, potassium content in grains in both seasons. However, Gemmiza 9 cultivar produced the longest spikes and the highest values of protein percentage in grains in both seasons. Whereas, Sakha 93 cultivar recorded the highest values of 1000 – grain weight at the same time the lowest values of other studied characters in both seasons.
Application of 100 % mineral nitrogen fertilizer alone produced the highest values of all studied characters. Application of 75 % mineral nitrogen (67.5 kg/fed) + 25 % organic nitrogen "compost" (22.5 kg/fed) came in the second rank after application of 100 % mineral nitrogen alone without significant differences between them in some studied characters in both seasons.
All studied characters of wheat plants gradually increased as a result of increasing potassium fertilizer levels from 0 to 48 kg K2O/fed in both seasons. Generally, maximum means of all studied characters were produced from fertilizing wheat plants with 48 kg K2O/fed in both seasons.
It could be recommended that fertilizing Gemmiza 10 cultivar plants with mineral nitrogen (67.5 kg N/fed) + compost (22.5 kg N/fed) + 48 kg K2O/fed to enhance wheat productivity and also to reduce sources of environmental pollution and maintain human health.

Plant growth and yield of wheat crop in saline soils and water may be increased by optimum fertilization management. The aim of this study was to investigate the response of new promising wheat genotypes to various nitrogen levels under various irrigation water salinity levels.To achieve this aim two experiments were conducted at the Experimental Farm of Dierab Station, Faculty of Agriculture and Food Sciences, King Saud University, Riyadh city, Kingdom Saudi Arabia during 2008/2009 and 2009/ 2010 seasons. The experiment was laid out in strip-split plot design with three replications. The vertical plots were allocated with three salinity levels of irrigation water (1000, 2000 and 4000 ppm). The horizontal plots were assigned to three nitrogen levels (100, 200 and 300 kg N/ha). While, the sub-plots were devoted to seven genotypes (KSU 101, KSU 102, KSU 104, KSU 105, KSU106 and Youkora Rojo).
The main results could be summarized as follows; the salinity levels significantly affected the yield and yield components of wheat whereas, they were significantly decreased as salinity level was increased up to 1000 ppm. The optimum nitrogen rate was 200 kg N/ha. The new released genotypes showed superiority against the commercial variety i.e. Youkora Rojo under normal and salinity conditions. The best released genotype was KSU102 followed by KSU 101 and KSU103.
Increasing nitrogen rate at high salinity level of irrigation water is not favorable, whereas it significantly decreased wheat grain yield and main yield components. By the way, 200 kg N/ha was the optimum under salinity conditions. The new tested wheat variety confirmed its salinity tolerance rather than common American variety.
It can be concluded that, fertilizing wheat genotype KSU102 with 200 kg N/ha could be recommend to maximizing wheat productivity under salinity conditions.
