A field experiment was carried out at the Extension farm in Province 41 of Husseiniya, Babylon Governorate to study the effect of foliar nutrition with some of nano-fertilizers and nano-amino acids on growth and yield of wheat cultivar Adana 99. The experiment included 8 treatments of Nano chelated super fertilizer (NCSF), nano-amino acids (AA), nano potassium K (NK),di (NCSF +NAA),(NCSF +NK), (NAA+NK), tri (NCSF +NAA+NK) and spray with water only as control for comparison with three replicates in a simple one-way experience using RCBD design. A number of growth criteria in plant and yield (quality and quantity) parameters were recorded. Results indicated that significant response is obvious due to spraying of NCSF followed by the spraying combined of di (NCSF +NAA),(NCSF +NK) and (NAA+NK) tri (NCSF +NAA+NK), treatments respectively in all growth and yield parameters of wheat with an increment of the spray foliar (NCSF) of 81.66 cm, 11.88 cm, 51.99 spad, 118.57,32.66,26.33 and 69.43 µg g−1 for plant height, length of spike, total chlorophyll, concentration of Fe, Cu,Zn and Mn in grain respectively compared to control treatment. The same treatment had grain yield and protein of 5.836 Mg ha−1 and 809.93 kg h−1 compared to control, harvest index were in the range (from 35.37 to 44.57 %) for control and tricombination spraying respectively. The highest grain yield and agronomic productivity was achieved when foliar nutrition of tri nano mixture of (NCSF +NAA+NK) (7.036 Mg h−1 and 2570kg kg−1).

A study was conducted to evaluate bacterial contamination in hairdressing and beauty salons in Thi-Qar at Alnasiriyah city. Samples were collected from ten different salons. The samples were collected from scissors,comb, razor, dryer, sink, and table tools. The isolates obtained were examined and identified using microscopic examination, colonial morphology and biochemical characteristics. Six bacterial species were isolated and identified. The bacterial isolates include Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus spp, Micrococcus Spp,Enterococusspp and Enterobacter. Isolated from some men's salons and shaving tools and the highest frequency of bacteria was in the salon of Nawras by 15%, Salon Ahmed by 12.5% , more bacterial isolation of shaving tools,sink,razor and the presence of this potential pathogen is an indication that hairdressing salons could be contributing to the spread of infection.

An effective protocol for the mass production of cauliflower microshoots was refined using the meristematic layer of cauliflower curd. The meristimatic layer was excised, homogenized using a commercial blender and separated into desirable size classes and cultured in liquid culture media containing 2 mg/L kinetin, 1 mg/L IBA (indole butyric acid) and different types and concentrations of sugars. Among several concentrations of sucrose derived from sugar beet, the use of 3 % concentration was found to be the optimal. Fructose, glucose and maltose were also tested at 1.5, 3, and 4.5 % concentrations and compared with the use of 3 % of sucrose which was considered as a standard (control). The best explants response was obtained using maltose but without a significant difference compared with the control. The effect of the source of sucrose on the development of cauliflower culture was also investigated using different concentrations of sucrose derived from both sugar cane and sugar beet. The use of 4.4 % sugar cane sucrose was found to be the best in terms of the number of developing microshoots. The results reported in this study helps to increase the effectiveness of the cauliflower micropropagation system and to reduce the cost of micropropagule per unit of production.
