Trichoderma asperellum, a potential fungal biocontrol agent against Aspergillus niger 2019-02-28T08:57:12+00:00 Rupa Verma Abhijit Dutta Ashok Kumar Choudhary Sudarshan Maurya <p><em>Trichoderma asperellum</em> is free-living, ubiquitous fungus which is very common in the habitat of soil and root ecosystem, is known as a potent opportunistic, avirulent plant symbionts and it parasitizes several soilborne phytopathogens. <em>Aspergillus niger </em>is well known black mold which causes several storage diseases. Among the storage diseases, black mould disease of onion is an important disease which is caused by <em>A. niger</em>. Antagonsitic potential of <em>T. asperellum</em> was assayed against three isolates of <em>A. niger </em>[RC1, RC2 (isolated from soil samples of Farm 1 and 2) and RC3 isolated from diseases onion]. Antagonistic efficacy of<em> T. asperellum </em>of <em>A</em>. <em>niger</em> almost similar against all the test isolates. Percentage inhibition of radial growth (PIRG) of <em>A. </em><em>niger</em> by <em>T. asperellum</em> inhibited 55.17% within five days, 77.20% within 7 days and 92.06% in 12 days. Antagonistic efficacy of <em>T. asperellum</em> can be exploited in the management of black mould disease of onion.</p> 2017-10-01T00:00:00+00:00 ##submission.copyrightStatement## Bullying at High Schools: Scenario of Dhaka City 2019-02-28T08:57:05+00:00 Sabrina Mahmood Shaheen Islam <p>Incidence of bullying among school children is very common and well recognized. The present study explored the existing scenario of bullying in high schools in Dhaka city. Phenomenological approach was used to gather and analyze focus group discussion data from 60 parents, teachers and students from both English and Bangla medium school, selected through convenient sampling. The qualitative analysis using software NVivo, revealed seven forms of bullying such as verbal, emotional, exclusion, physical, sexual, cyber, and race, to be prevalent among high school children. Though bullying found to affect large numbers of high school children in both Bangla and English medium, according to teachers’ report, physical and emotional bullying were more common in Bangla medium, while frequency of verbal, sexual, and cyberbullying were high in English medium. Teachers also reported that student of grade 9 and 10 experienced more sexual and cyberbullying than other classes. It was evident that bullying took place at anywhere and everywhere in the school premises, like in classroom, playground, bathroom, around the campus, or even in school bus. Common causes, probable consequences and prevention strategies on bullying were also identified. Seeking attention was found to be an important factor in bully behavior. Opinion of parents, teachers and students about experiences and probable prevention plan were considered to work out a helpful intervention program for bullying in the future.</p> 2017-10-01T00:00:00+00:00 ##submission.copyrightStatement## Temperature effects on growth of the biocontrol agent Pantoea agglomerans (An oval isolate from Iraqi soils) 2019-03-03T09:06:13+00:00 Zaid Raad Abbas Sawsan Hassan Authman Aqeel Mohammed Majeed Al-Ezee <p>The growth response of the biocontrol agent <em>Pantoea agglomerans</em> to changes in temperature was determined <em>in vitro</em> in nutrient yeast extract-sucrose medium. The minimum temperature at which <em>P. agglomerans</em> was able to grow was 4°C and the maximum temperature was 42°C. This study defines the range of environmental condition (Temperature) over which the bacteria may be developed for biocontrol of postharvest diseases.</p> 2017-10-01T00:00:00+00:00 ##submission.copyrightStatement## In vitro screening of Trichoderma viride against Albugo candida - white rust pathogen of rapeseed-mustard 2019-03-03T09:06:10+00:00 Yengkhom Premlata Devi G. K.N. Chhetry <p>Field experiments on white rust of rapeseed-mustard were conducted at Kakching located 45 km away from Imphal, Manipur during two consecutive <em>rabi </em>seasons (2014-15 &amp; 2015-16) under organic farming. Using dual culture technique of <em>Trichoderma viride</em> and <em>Albugo candida </em>resulted in significant effect in all the varieties except in between M-27 (V<sub>3</sub>) &amp; Ragini (V<sub>4</sub>). The percent inhibition of mycelial growth over control was found to be highest in V<sub>4</sub> (58.78%) and lowest in local cultivar<em>, </em>Lamtachabi (V<sub>2</sub>) i.e. 33.17%.</p> 2017-10-01T00:00:00+00:00 ##submission.copyrightStatement## Seasonal Study of some Chemical Parameters in Daryabganj Lake, District Etah 2019-03-03T09:06:05+00:00 Kuber Singh H. N. Sharma <p>In India, great regional differences are found in the topography, geology, climate etc. As a result of these differences, the limnological resources (lake, pond &amp; reservoirs) are very unevenly distributed. The inland fisheries include, besides capture fishes of the lake, rivers and large bodies of waters, the culture fishery whose contribution to the dietary of man is of the highest importance. From the catch statistics of these waters, it becomes quite clear that fish production is low in comparison to those of other countries like China, Japan, Indonesia etc. The efforts for increasing fish production in inland waters are underway; however, any effort towards developing the fish resources requires intimate knowledge.</p> 2019-01-14T00:00:00+00:00 ##submission.copyrightStatement##
