Influence of Timing of Herbicide Application on Winter Canola Performance
Canola (Brassica napus L.) is an important source of vegetable oil for humans and canola cake is a nutritious feed for animals. However, weeds are one of the major constraints in canola production in the southeastern regions of the United States causing loss upto 50 percent in yield. Control of weeds in spring canola has been reported but research on weed control in winter canola has not been well documented. Therefore, research experiments were conducted from 2005 to 2007 to evaluate the effects of herbicide application timings on canola performance. Results showed that pre-emergence timing of trifluralin @ 1 kg ai ha resulted 496 kg ha , 411 kg ha , 502 kg ha higher canola yield as compared to control in 2005, 1 1 1 1 2006 and 2007, respectively. Pre-emergence application timing of trifluralin gave 79% less weed biomass than control plots. Increasing weed density and weed biomass significantly reduced the canola yield whereas increasing plant height increased the canola yield significantly. This study revealed that herbicide application timing significantly reduced weed biomass and increased canola yield.
Growth and Oil Production of Canola as Affected by Different Sulphur Sources.
A field experiment was carried out in the Research and Production Station, National Research Centre, El- Nobaria Site, Beheara Governorate- Delta Egypt. The experiment was conducted to evaluate the effect of different sources and rates of sulphur on canola growth and oil production. The obtained results showed:  Treatments can be arranged in descending order as follows: ammonium sulphate > ammonium thiosulphate > elemental sulphur.  Elemental sulphur gave the lowest values of the growth, seeds and oil yield along with mineral and chemical content of canola seeds.  Ammonium sulphate addition in plant media enhanced all parameters of canola growth, seeds and oil yield as well as chemical and minerals content of canola seeds especially with 300 Kg/fed rate.
Microbial flora of frozen tail meat from captive Nile crocodiles (Crocodylus niloticus).
Frozen tail meat samples from nine Nile crocodiles (Crocodylus niloticus) were evaluated for microbial numbers and types. Microbial analyses yielded a mean aerobic plate count (APC, 30 degrees C) of 4.86 log cfu/g, a mean coliform count (TC, 37 degrees C) of 3.77 log cfu/g and a mean faecal coliform count (FC, 44 degrees C) of 3.40 log cfu/g. Salmonella was isolated from three samples, and beta-haemolytic streptococci from two samples. Yersinia, Aeromonas, Staphylococcus aureus and Bacillus cereus were not isolated. Typical bacterial genera recovered included Flavobacterium, Pseudomonas, Acinetobacter, Enterobacter, Moraxella, Micrococcus, Staphylococcus and Streptococcus.
