Abstract: The radiation hazards indices of common silhouette plants used in homes decoration were studied at two seasons; spring and summer. Twelve species of silhouette plants were collected from nurseries in Baghdad, six of them were collected in spring season others in summer season, each group were positioned in the laboratory at normal conditions. The measurements were carried out using NaI (Tl) gamma-ray spectrometry. Results shown a little difference between the mean specific activities of the radionuclides, they were 161.2±11.8, 11.2±1.2Bq/kg, and 5.8±0.5Bq/kg in spring season plants, 159.5±21.1, 5.4±0.8Bq/kg, and 6.4±0.4 in summer season plants for K-40, Bi-214, and Tl-208 respectively. According to these results the mean radiation hazard indices (The radium equivalent activity, absorbed dose rate, annual effective dose equivalent, external hazard indices, annual gonadal dose and excess lifetime cancer risk) were also convergent to each other in plant samples of both groups. The highest specific activities were appeared in Dareseny plant 197.11Bq/kg, 15.94Bq/kg, and 7.8 Bq/kg for K-40, Bi-214, and Tl-208 respectively. While in summer season the K-40 (265.9Bq/Kg) and Bi-214 (8.6Bq/Kg) were higher in sygonium, and Tl-208 is higher in Ficus Elatic (9.2Bq/Kg). All results are within the recommended values.

Abstract: This research work was carried out, to assess the impact of cassava in Nigeria. 4 Local governments, namely: (Ife East, Ife South, Ife Central and Ife North), local government areas were sampled. 4,000 open questionnaires were distributed to the 4 Local Governments, out of which 1000 was used for the farmers in each local government. A total of 40 different locations were visited in all the four Local Governments, out of which 100 questionnaires were used in each location. It was gathered that above 75% of the farmers from the four local governments, supported, assessing the impact of cassava in Nigeria. while below 25% of the farmers, could not even understand whether or not there was any need, to assess the impact of cassava in Nigeria. The results from the questionnaires when using Pearson two-tailed correlation coefficient revealed that there was a significant difference from the summary data collected from the farmers within the four local government areas visited and sampled, (p > 0.05) table 5. This shows a strong positive correlation, which implying that, to assess the impact of cassava in Nigeria, is strongly influenced and enhanced the farmer’s support in our society, and therefore has made the research work to become a reality, (p>0.05) table 5. The reasons may be due to the fact that, cassava farming is not mainly done, to produce items, solvents, alcohol, glucose, animal feed, energy, fertilizers, and some extra by-products, but many industries in Nigeria also used cassava tubers, as major raw materials for: cassava flour factories, noddles production industries, alcohol and liquor production industries, garri factories, fufu producers etc. Pie chart was used to depict the summary data of each of the local government areas sampled in Ile–Ife Kingdom, of Nigeria.

Abstract: Mineral fertilizer use is expanding in Jute growing countries to satisfy fiber demands. Fertilizer consumers are being asked to improve fertilizer use efficiency through better management in their fields to provide a healthy economy. Following the thought a field experiment was established to determine the influence of mineral fertilizer (NPKS) on growth and yield of the advanced C. olitorious breeding line of O-043-7-9. We selected three different locations under Bangladesh Jute Research Institute to examine jute crop response to optimum fertilizer combination and the yield variability by 10 different nutrient combinations. Because of the essentiality of N, P, K, and S fertilizer combination on Jute fibre production and their effects on its growth were studied. The lower levels of N, P, K and S were zero applications in specific treatments. N, P, K and S were positively correlated with yield level. Over time, the simple effect of N exhibited an increased positive trend only when applied limited to 100kg/ha, while simple effects of P and K increased sharply at the rate 10 and 30 kg/ha respectively. The zero fertilizer treatment yielded decline for each mineral in specific treatment in the trial. Fertilizer N, P, K and S were utilized more efficiently in fully balanced combination. After the findings from three different locations for growth, yield and agronomic characteristics, we can draw the conclusion that the combination dose of N100 P10 K30 S15 Kg/ha may need to be applied for breeding line O-043-7-9 cultivation in Bangladesh.

Abstract: A pot experiment was conducted in the Net House of “Field Laboratory of Plant Stress Management” in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from October 2016 to March 2017. The two factors experiment was laid out in Complete Randomized Design with five replications. Factor A is three tomato varieties viz. V1= Exotic line 1 (Korean), V2= Exotic line 2 (Taiwan) and V3= BARI tomato 14 and factor B is seed priming treatment viz. P0= No priming (Control), P1= Hydropriming (distilled water), P2= NaCl priming (50 mM) and P3= KNO3 priming (200 mM). The total treatment combinations were (4×3) 12 and 8 dS/m fixed salinity maintained for all the pots. The experimental results exhibited that seed priming treatment significantly affected growth, yield and quality parameters of tomato. The highest plant height (137.10 cm), number of fruits per plant (40.92) and fruit yield per plant (585.00 g) were found from V1 under 8 dS/m salinity level. In case of seed priming, the highest plant height (150.10 cm), number of fruits per plant (48.11) and fruit yield per plant (755.80 g) were recorded from P2 mostly at 8 dS/m salinity level. Regarding the combined effect, the highest plant height (187.00 cm), number of fruits per plant (55.00) and fruit yield per plant (829.30 g) were found from V1P2 under 8 dS/m salinity level. So, Exotic line 1 with NaCl priming (50mM) showed better performance for growth, yield and quality of tomato under saline condition.

Abstract: In Brazil there is lack of information about the weed emergency periodicity from the seed bank in the soil. This information is important to the elaboration of a strategy of weeds management. The objective of this research was to evaluate emergency periodicity of weeds by a frequent application of glyphosate used to determine the seeds bank in two systems of handling of the soil (tillage and no tillage). The experiment was conducted in the district of Piracicaba-SP, during two years, on the Dept. of Vegetable Production of ESALQ/USP. The experimental design was of completely randomized blocks with subdivided portions, repeated four times. The treatment consisted in glyphosate applications rates of 0, 540, 720, 900, 1080, 1260 and 1440 g.i.a ha-1. Weeds were sampled through the method of iron square and the seeds bank was determined by withdrawing of soil in depths of 0-2.5, 2.5-5.0, 5.0-10.0, 10.0-15.0 and 15.0-20.0cm. The herbicide glyphosate was shown effective in controlling weeds. In the year of 2001, they happened periodicitys of emergency more differentiated in the no tillage that in the tillage, but in the year of 2002, those differences of periodicitys in the species were not as expressive. The seeds concentrated layer superficial of the soil, in the no tillage system, while the tillage preparation in the soil distributed the seeds in the profile of soil.
