  Nile tilapia – probiotic - aflatoxin B1- Psedomonus floresence
  This study was conducted to investigate the ability of a probiotic; Pediococcus Acidilactici in a commercial product named Bactocel,to overcome the toxic effects of aflatoxin B1 (AFB1) on Nile tilapia (Oreochromis niloticus) fingerlings. In which 0.1%, 0.2% and 0.3% Bactocil were added to an aflatoxin (150 ppb aflatoxin B1) diet for fingerlings. These rations were fed 6 days a week at 3% of actual biomass in glass aquaria in duplicate (2 aquaria / treatment) in an indoor feeding experiment that lasted 11 weeks. The aflatoxic diet had adversely affected the growth performance, survival rate, feed and protein utilization, carcass composition and health status of fish. Generally, the obtained results from the present study indicated that adding 0.1% and/or 0.2% Bactocil to fish rations could be used as detoxifying agents for aflatoxins. Moreover, fish fed Pediococcus acidilactici had obtained higher resistance against challenge with Psedomonus floresence pathogenic bacteria especially at feeding the concentration of 0.2% Bactocil

  Wheat- Sugar
  Two field experiment were conducted at Sakha Agricultural Research Station, Agriculture Research Center, Egypt, in 2010/2011 and 2011/2012 seasons, to study the effect of two planting patterns (ridges 60cm and beds 120cm) and intercropping wheat (Tritium eastivum, L.) cv. Sakha 93 with sugar beet (Beta vulgaris, L.) cv. Diamond on the productivity of both crops. Intercropping systems were solid crop, intercropping sugar beet with wheat in hill spaces 20, 40, 60 and 80cm. Sugar beet was sown on one side of ridge or two sides of bed for solid or intercrop system. Wheat was sown on another side of ridge and two rows on top of bed at all intercropping systems.
Beets sown on ridges were significantly superior to those sown on beds in root length, gross sugar%, white sugar% and white sugar yield per feddan in both seasons and juice purity in the first season, only. The inverse was true in K+ Na concentration in root juice in the first season. No significant differences were detected between the two planting patterns in root diameter, top weight, root weight, root yield and top yield in both seasons. In respect to wheat, there were no significant differences between the two planting patterns in plant height, number of spikes per m2, spike length, grains number and weight per spike, 1000-grain weight, grain yield, straw yield and harvest index.
There was a significant difference among intercropping systems in top, root and sugar yields and their attributes as well as root quality in the two seasons. Decreasing density of wheat increased root length, root diameter, root yield, top yield, total sugar%, white sugar% and juice purity%, while it decreased concentration of impurities (K, Na, ?-amino-N and K+ Na), alkalinity coefficient and losses sugar%. Root and sugar yields per feddan produced by solid beet plants and its intercropped with wheat at hills 80cm apart were practically the same and significantly surpassed those intercropped with wheat at hills 20cm apart in both seasons. In respect to wheat, increasing wheat density increased plant height, number of spikes /m2, 1000-grain weight, grain yield, straw yield and harvest index. The inverse was true in spike length, grains number and weight per spike.

The highest root and white sugar yields were recorded in solid beet followed by its intercropped with wheat on ridges and beds at 80 and 60cm between hills with no significant difference among them in both seasons.
Land equivalent ratio (LER) values were greater than one at any intercropping systems. Intercropping sugar beet and wheat increased land usage by 37, 35, 31 and 33% over monocultures of both crops at wheat hill spacing of 20, 40, 60 and 80cm

  Canola – N-fertilizers – Micronutrients – seed oil contents –Growth – yield components.
  Two field experiments were carried out in 2010/2011 and 2011/2012 winter season at Sakha agricultural research station to study the effect of nitrogen fertilizer levels (30,45and 60 Kg/fed) and foliar fertilization (foliar spraying with urea 2%, superphosphate4%, and mixture of micronutrients (100 ppm Fe, 140 ppm Zn, 120 ppm Mn) on growth, yield and its components of canola C.V. serw4.
Results indicated that Plant height; number of branches /plant and leaf area /plant as well as chlorophyll a, b and total photosynthetic pigments in leaves were significantly increased with increasing nitrogen level at two growth stages in both seasons. Foliar nutrient application of urea followed by mixture of micronutrients significantly improved growth attributes. Increasing N fertilizer up to 60 Kg N /fed and foliar spraying with urea 2% and micronutrients led to significant increase in plant height, 1000 seed weight, seed yield/plant and seed yield (Kg/fed) and oil yield (Kg/fed) ,however seed oil content was significantly decreased with increasing fertilizer nitrogen rate and foliar application. The interaction among levels of N fertilization and foliar spraying with nutrient application proved significant in most of the investigated growth traits and yield of canola plants.
It could be concluded that nitrogen applied at 60 Kg N/fed and spraying with urea2% followed by mixture of micronutrients to canola plants ,which gave the highest both seed yield/fed and oil yield/fed
