An Experiment was conducted during 2006-2007 to study the effect of some eco-friendly treatments on severity of leaf bight (Bipolnris sorokinianm, number and weight of grain per spike and grain health of wheat. Seeds of wheat variety Kanchan were collected from a farmer of Bansal district. Apparently healthy seeds were sorted out from the seed lot. Both unsorted and apparently healthy seeds were treated with hot water at 50°C for 5 minutes, brine solution (2% wlv NaCI) for 15 minutes, sun drying for 14 hours and polythene solarization for 14 hours. Unsorted and apparently healthy seeds were planted and 0.05% boron solution was applied as foliar spray at tillering stage. Two checks were maintained, unsorted and apparently healthy seeds, and planted without any treatment. At all stages of data collection. the highest severity of leaf blight on flag leaf and penultimate leaf were recorded under control. where unsorted and untreated seeds were planted followed by the treatment where apparently healthy seeds were planted without any treatment. Other treatments caused significant reduction in leaf blight severity and percentage of diseased seeds as compared to control. The treatments gave significant increase in number and weight of grain per spike and percentage of healthy grain. Considering the above parameters, pre-sowing treatment of apparently healthy seeds with hot water, brine or sundrying were noted as effective ceo-friendly methods to reduce leaf blight severity and to increase grain yield and healthy seeds of wheat.

(Dept. of CE, CUET, 19-Dec-2018) Sarker, A.; Iqbal, M. B.; Rahman, M. M.; A-Noor, M. C.; Rahman, M. A; Islam, M. R.
Stabilization of problematic soils with fly ash not only improves engineering properties of soil but also provides a solution to challenges of fly ash disposal. Approximately 52,000 tons of fly ash produced annually at Boropukuria coal-based power plant in Bangladesh require a huge disposal area and create environmental problems. This paper reports the results of laboratory investigation carried out on expansive soil collected from Rajendrapur area stabilized with fly ash in varying percentages. Here, 4% cement is used as an activator. The effect of cement with varying fly ash contents are correlated with soaked California bearing ratio (CBR) value, swelling index and Atterberg limits of stabilized soil. The study finds that soaked CBR value of the soil improves from 1.73% to 26.07% after adding 6% of fly ash for 14 days of curing. With increasing of more fly ash content, strength decreases. So optimum value of fly ash content is 6% for which highest strength is obtained. Moreover, swelling index of the collected soil with 4-days soaking condition is found to be decreased by 47% when 6% fly ash is added. The outcome of this study will guide road engineers of Bangladesh to use fly ash as a stabilizing agent to improve the properties of subgrade

The Experiments were carried out during the period of 2009 to 2013 on the epidemiological status an :--,__ -=,",./ .., prescriptions used for the management of cucumber mosaic disease with a view to simulate a diagnosis and prescription model. The survey area covered five upazillas viz. Mymensingh sadar, Kushtia sadar, Kumarkhali, Chandina and Sher-e-Bangla Nagar under four districts viz, Mymensingh, Kushtia, Comilla and Dhaka where altogether 250 farmers field were considered for observation. The highest disease incidence of mosaic of cucumber (37, I%) was recorded at Kumarkhali, while the lowest were (33.9%) in Boira Keyotkhali, Gemini virus was detected as causal pathogen for cucumber mosaic disease. The model prescriptions issued by Plant Disease Diagnostic Clinic (PDDC) found effective in the farmer's field against the Cucumber Mosaic disease in selected locations were subjected to re-evaluation under different experimentations at Plant Pathological field laboratory at BAU farm. Economically affordable management practices were re-tested in five locations of Bangladesh. Based on the re-investigation results, the model prescriptions were finally selected for the vegetable growers of the country. Model diagnosis and prescription have been proposed. These were Surni-Alpha @ I mlfl sprayed 4 times at 15 days intervals starting from first sign of the disease at 60 days after sowing for cucumber mosaic disease. The management practices were reduced of disease incidence (73.5%), disease severity (73.8%), yield increased (74.4%) over control and benefit cost ratio (BCR) was 3.40, respectively.
STATUS OF INDISCRIMINATE USES OF ANTIBIOTICS IN LIVESTOCK AT NARAYANGANJ SADAR, NARAYANGANJ
(Sher-e-Bangia Agricultural University Research System (SAURES), 2023-07) Robin, A. I.; Hossain, H.; Taslima, M.; Jahan, M. S.; Islam, M. R.
Antibiotic overuse, the prevalence of diseases, and the emergence of medication resistance are the main reasons why rash antibiotic use has attracted significant attention worldwide. By assessing the prescribers' patterns of prescribing antibiotics for patients, this cross-sectional survey-based study aims to represent a true picture of antibiotic use in Narayanganj Sadar, Narayanganj. It was conducted by making specific interviews with 60 farmers using a self-designed standard questionnaire. As a result of this study, we know that 38.3% of animals received antibiotic prescriptions, and that young animals (those age under 2 years old) received these prescriptions more frequently (53.8%). According to this study, the majority of antibiotics were used to treat microbial infections about 18 out of 23 animals (78.3%). Contrary to goat species, cattle species utilized antibiotics at a rate that is 6.69% greater. All prescriptions are for ceftriaxone (22%), marbofloxacin (18%), ceftiofur (4%), and ciprofloxacin (4%), in addition to amoxicillin (26%) and penicillin (26%). The13% of farmers had no idea how an antibiotic worked, how long it had lasted, or how to use it. About 69.5% of animals received prescriptions from non-registered veterinarians. It was obvious that farmers were not sufficiently aware of the usage of antibiotics, lacked adequate education and did not practice regarding drug usage policies in all situations. The spread of bacterial resistance to antibiotics and other health issues are caused by this illogical use. Therefore, community base awareness regarding the discriminate and indiscriminate use of antibiotics in livestock production.
