Generally, it is obvious that Giza-2 cultivar surpassed Giza-1 cultivar in the first and the second seasons, respectively in plant height (cm), Pod length (cm), number of branches/plant, weight of 100 seeds, seed yield per plant (g) and per fed (ton), crude lipids, total soluble sugars and total phenolic compounds and it is obvious that Giza-1 cultivar surpassed Giza-2 cultivar in both seasons in total nitrogen, crude protein and total alkaloid.

In Upper Egypt, the level of broomrape infestation is so high because of high temperature which led to decline of faba bean area. The control of two field experiments were conducted in a heavy infested soil with broomrape inShandaweel Research Station, Sohag Governorate, Agricultural Research Center during 2016/17 and 2017/18 winter seasons to study the effected potential integration between nitrogen and manure fertilizers hand pulling and interaction between selective herbicides and salicylic acid on control for broomrape and increased faba bean productivity. Each experiment contained three levels of (nitrogen fertilization at rate 20 kg/fed., organic manure fertilizers at rate 20 m 3 /fed, nitrogen fertilization at rate 10 kg /fed + organic manure fertilizers at rate 10 m 3 /fed and without fertilizer (untreated check) and eight broomrape control treatments (Glyphosate twice at rate 75 cm 3 /fed -Glyphosate once at rate 75 cm 3 /fed. + Salicylic acid once at 200 mg/one liter water -Glyphosate once at rate 50 cm 3 /fed + Salicylic acid once at 200 mg/one liter water -Salicylic acid thrice at rate 200 mg/one liter water -Hand pulling twice and untreated (control). Split plot design in three replications were used. Faba bean cultivar was Giza -843 and plot area was 10.5 m 2 . The results revealed that fertilizers reduced significantly Orobanche infestation in 2016/17 and 2017/18 seasons. Addition of 20 kg N-fertilizer/fed and N-fertilization at 10 kg /fed + O.M-fertilizers at 10 m 3 /fed increased number plants of faba bean/plot by (10.28 & 6.84%) and (2.84 & 1.18%), decreased number of plant infestation/plot by (33.41 & 17.40%) and (13.86 & 10.58%), number of broomrape spikes /plot by (31.49 & 22.16%) and (15.44 & 12.83%) and dry weight broomrape spikes/plot by (31.38 & 22.00%) and (15.45 & 12.84%) in 2016/17 and 2017/18 seasons, respectively, compared with non-fertilizer check. Nitrogen fertilization and nitrogen fertilization +Organic manure fertilizer recorded the highest values for plant height (cm), number of branches/plant, number of pods/plant, weight of pods/plant (g), seed weight/plant (g), 100-seed weight (g) and seed yield /fed in both seasons compared with non-fertilizer. Broomrape control treatments decreased significantly numbers and weight broomrape spikes (g/plot) of Orobanche in 2016/17 and 2017/18 seasons. Glyphosate at rate twice at 75 cm 3 /fed and Glyphosate once at rate 75 cm 3 /fed. + Salicylic acid once at 200 mg/one liter water increased number plants of faba bean/plot by (12.44 & 12.35%) and (4.61 & 4.12%) and decreased the number of plant infestation of faba bean/plot by (59.43 & 46.69%) and (52.52 & 51.54%), number of broomrape spikes /plot by (55.06 & 50.64%) and (49.63 & 49.48%) and dry weight of broomrape spikes/plot by (55.10 & 50.69%) and (49.62 & 49.47%) in 2016/17 and 2017/18 seasons, respectively, as compared with untreated (control). Glyphosate at rate twice and glyphosate once + Salicylic acid once gave the heist values number of pods/plant, weight of pods/plant (g), seed wei...

T HE PRESENT investigation was carried out at Shandaweel Agricultural Research Station, Sohag Governorate (latitude of 26°33'N, longitude of 31°41'E and Altitude of 69m), in the two successive seasons 2016/2017 and 2017/2018 to investigate the effect of study the effect of nitrogen, phosphorus and filter cake on yield and quality of sugarcane. The filed experimental work was carried out in a Randomized Complete Blocks Design (RCBD) using a split-split plot arrangement in three replications in both growing seasons. The results showed that increasing nitrogen levels from 150 up to 210kg N/fad resulted in a significant increase in plant length, diameter, stalk weight, number of millable canes, cane and sugar yields, as well as brix, sucrose, quality and sugar recovery percentages in both seasons. Super phosphate addition by rates 30kg P 2 O 5 /fad resulted in a significant increase in plant length, diameter, number of millable canes, stalk weight and cane and sugar yields, as well as brix, sucrose and sugar recovery percentages in both seasons. Results showed that the addition of filter cake by 4tons/fad give a significant increase in plant length, diameter, number of millable canes, stalk weight, cane and sugar yields, as well as brix, sucrose and sugar recovery percentages in both seasons.

The experimental field was conducted at the experimental farm, Fac. of Ag., Al-Azhar U., Assuit, during two growing summer seasons of 2018 and 2019. A field experiment was designed as randomized complete block with split split-plot arrangement of treatment with three replications. The current study aims to evaluate different irrigation methods (conventional and alternative furrows) and nitrogen fertilizer Sources (urea as fast nitrogen fertilizer and ureaform as slow one) for maximizing the production of some cotton varieties (G80 and G90) as well as to define the most favorable irrigation manner that achieves the highest water productivity and high cotton yield and its quality. The results showed that alternate furrow irrigation (AFI) saves about 12 % of the actual evapotranspiration (ETa) compared to the conventional furrow irrigation (CFI). The ETa increased with urea fertilizer compared to ureaform fertilizer. The estimated evapotranspiration (ETo) values in both growing seasons followed the descending order of FAO Penman-Montithe > Turc > Hargreaves. It is clear that the Hargreaves equation calculated ETo efficiently for cotton crop growth under Assiut region circumstances. The AFI increased the crop water productivity (CWP) and irrigation water productivity (IWP) by 13 and 15%, respectively compared to the CFI. The irrigation methods during both growing seasons had significant effects on cotton seed yield, cotton lint percentage, boll weight, lint index, seed index, 2.5% span length, length uniformity ratio, fiber strength (pressly index) and fiber fineness. The AFI realized positive higher effect on cotton traits and yield quality than those under (CFI).water and nitrate leaching from continuous and alternate furrow irrigated rapeseed and maize fields.

Two field experiments were conducted at Bardies, Sohag Governorate, Egypt, during the summer seasons of 2011 and 2012. The objective of this investigation aimed to study the response of some maize hybrids to different nitrogen fertilization levels and filter mud cake. A split-split plot design with three replications was used. Two Maize Hybrids (H1-Single cross Watania-4 and H2-Three way cross-310) were allocated in the main plots. Nitrogen fertilization levels (N1-80, N2-100 and N3 120 kg N/fed) were distributed in the sub plots. While, organic fertilizer (filter mud cake B1-Control (without addition, B2-one ton/fed, B3-1.5 ton/fed and B4-2 ton/fed) were randomly distributed in the sub-sub plots.The results indicated that single cross Watania-4 surpassed significantly three way cross 310 in ear length cm, ear diameter cm, number of rows/ear, number of kernel/ear, ear weight gm, grains weight/ear gm, 100-grain weight gm and grain yield (ardab/feddan). There were gradual and significant increases in ear length cm, ear diameter cm, number of rows/ear, number of kernel/ear, ear weight gm, grains weight/ear gm, 100-grain weight gm and grain yield (ardab/feddan) resulted from raising mineral N-level from 80 to 100 and 120 kg N/fed.There were significant differences in the studied traits as affected by the organic fertilizer (filter mud cake) in both seasons. Under Sohag Governorate conditions of the present work, growing single cross Watania-4 fertilized with 120 N/fed and applied 2.0 ton filter mud cake that were recommended to get the maximum grain yield (ardab/feddan).
