Response of cotton plant to the indole-3-butyric acid application under n fertilization rates.
Two field experiments were carried out during 2011 and 2012 seasons at Sids Agricultural Research Station. ARC, using cotton cultivar Giza 80 to study the effect nitrogen fertilizer rates (45, 60 and 75kg/fed) and foliar spraying of indole -3- butyric acid (IBA) at four rates (0, 10, 20 and 30 ppm) on growth characters, yield and yield components as well as fiber properties and chemical contents. Increasing nitrogen fertilizer rates from 45 to 60 or 75 kg/fed significantly increased for plant height, number of internodes/plant, internode length, number of fruiting branches/plant, boll setting percentage, number of open bolls/plant, boll weight, earliness percentage, seed cotton yield (Kentar/fed) and chemical contents of cotton plant (leaves and seeds). On the other hand, position of first fruiting node and fiber properties showed insignificant responded to nitrogen fertilization. Result revealed that the IBA at 20 ppm was significantly enhanced plant height, No. of internodes/plant, internode length, boll setting %, No. of open bolls/plant, boll weight, seed cotton yield, chlorophyll (A), carotenoids, protein and oil percentage. On other hand, position of first fruiting node, fiber properties, chlorophyll (B) and total chlorophyll. However, No. of fruiting branches and earliness % response only in one season. Generally, the interaction between N and IBA had highly significantly affected all studied characters, except position of first fruiting node, yield and yield components and chemical contents as well as (leaves and seeds) of cotton plant were not affected by the interaction between treatments with refer to apply 75kg N/F and spraying 20ppm IBA.

Screening of chickpea (cicer arietinum l.) genotypes for earliness, yield, yield components and resistance against fusarium wilt
Twelve chickpea ( Cicer arietinum L.) genotypes were evaluated for earliness, yield, yield components and resistance against fusarium wilt under field and laboratory conditions through two successive seasons; 2009/2010 and 2010/2011. Under field conditions, generally for both seasons, L 138 had the first grade in case of number of days for flowering (earliness), number of days for maturity, seed weight / plant (g), 100 seed weight (g) and seed yield / feddan (ardab). Also, the four Egyptian genotypes (Giza 88, Giza 1 and 2 and L 138) had better values than the eight ICARDA genotypes for the parameters mentioned before. At the first season the least total fusarium wilt for both seedling and podding stages were noticed in case of L 138 followed by G88 and F 97 – 195 C with averages of 11.52, 12.78 and 15.65%, respectively. At the second season it was the least with L 138 followed by F 97 – 195 C, G 88 and F 98 – 58 C with averages of 8.36, 9.55, 11.88 and 12.80%, respectively. Under laboratory conditions, chickpea genotypes leaf extracts (CLE) decreased Fusarium oxysporum f.sp < em>. ciceris linear growth than chickpea genotypes root extracts ( CRE ) with averages of 3.79 and 5.88 cm., respectively. The least linear growth in case of (CLE) cleared with L 138 and F 97 – 195 C with averages of 2.05 and 2.53 cm., respectively but F 98 – 58 C had the highest value with an average of 4.84 cm. Using CRE, also L 138 and F 97 – 195 C had the best effect in reducing the fungal linear growth with averages of 2.86 and 3.62 cm. respectively.

Forage Yield as Affected by Mixing Rates of Egyptian clover (Trifolium alexandrinum L.) With Ryegrass (Lolium multiflorum ) Grown in Sandy Soil.
Two field experiments were conducted during the winter seasons of 2008/2009 and 2009/2010 in Research and Production Station of National Research Centre, Al Emam Malek Village, Al Nubaria District, Al Behaira Governorate, Egypt. Experiments aimed to study potential of mixture of Egyptian clover with ryegrass to increase forage yield and its quality grown under sandy soil conditions.
Five treatments were used i.e ryegrass (pure stand) 12kg seeds/fed., clover (pure stand) 20kg seeds/fed., ¼ Ryegrass +¾ clover, ½ Ryegrass +½ clover and ¾ Ryegrass +¼ clover.
Fresh and dry forage yield/fed. were determined for the three cuts as ton /fed. (First cut 60 days after sowing, second 50 days from the first while third cut 40 days later.) during the two seasons. Chemical composition and nutritional evaluation for dry forage yield was conducted. The obtained results showed that treatment of mixing ¾ clover + ¼ ryegrass mixture was the best treatment in fresh and dry yields as well as chemical components and nutritive evaluation i.e. crude protein, crude fiber, ether extract,nitrogen free extract, ash, digestible crude protein and total digestible nutrient in both seasons (as combined analysis of two seasons).

Effects of Intercropping Sunflower with Sugar Beet under Different Plant Densities and Defoliation Levels on Yield and Production Efficiency of Both Crops
Two field trials were carried out in Agriculture Research Station, Giza, Egypt during 2009/2010 and 2010/2011 seasons to study the effect of intercropping sugar beet with different plant densities of sunflower (100%, 80% and 67% sunflower plants from pure stand) and four defoliation levels of sunflower plants (75, 50, 25% and 0% at milk ripe stage) on growth, yield and yield components of sunflower (Helianthus annus L.) and sugar beet (Beta vulgaris L.).
Sugar beet (c.v. Kawemire), as the main crop, was seeded in hills spaced 20 cm on two sides of wide ridges 120 cm apart, both in intercropping and monoculture patterns to achieve full stand of 35000-plants/ fed. Sunflower (c.v. Giza 102) as a sole crop was seeded in hills spaced 20 cm apart and one plant per hill on both sides of the ridges 120cm to achieve full stand 35,000 plants/fed. Intercropped sunflower was sown at one plant per hill spaced 20, 25 and 30cm on two rows in the top of ridges 120cm width. The experiments included 12 treatments, in addition to monocultures of sunflower and sugar beet as checks. The experiments were designed a Randomized Complete Block Design (RCBD) with three replications.
