A study was conducted to assess the present status of agricultural waste management by farmers in Trishal upazila of Mymensingh district, Bangladesh. During April to May 2015 and data were collected from the sample of 70 farmers and 5 farms. A structured interview schedule was used for collection of data. The study explored the relationship between the four selected type farming (independent variable) of farmers with their generation of agricultural waste (dependent variable). In this study the highest amount waste (straw and husk production) is closely related with the size of cropland. Straw production less than or equal 1000 kg is 36.62%, straw production less than or equal 10000 kg is 54.92%, straw production less than or equal 20000 kg is 5.63% and straw production less than or equal 30000 is 2.81% and husk production less than or equal 1000 kg is 35.71%, husk production less than or equal 10000 kg is 55.71%, husk production less than or equal 15000 kg is 8.57%. So as the dairy and poultry waste is also relate with the number of cows and birds. Average amount of dung is 8.87 kg per day and average amount of used litter was 46.36 kg per 800 bird production. For management biogas was suggested by 12.5 percent respondent. Composting and fish culture were suggested individually by 4.17 and 8.3 percent respectively. Due to manage agricultural waste efficiently it is necessary to initiating program to introduce the economic benefits of waste management and start training programs for farmers.Res. Agric., Livest.

This study elucidated and attempted to design and development of arsenic and iron removal unit for drinking water. The process of reducing iron and arsenic from water has been experimented by developing a unit in the Department of Farm Structure at Bangladesh Agriculture University, Mymensingh. In order to test the performance of the developed unit, arsenic contaminated water with four different concentrations like 0.05, 0.10, 0.15 and 0.20 mg/l were prepared in the laboratory and passed into the developed unit and the respective output concentrations were found to be 0.00, 0.01, 0.025 and 0.05 mg/l. The input and output concentrations of arsenic were tested in the chemical testing laboratory under the Bangladesh Institute of Nuclear Agriculture, Mymensingh. Iron contaminated water were collected from four selected tube wells of local Mymensingh and were also passed into the developed unit with four input concentrations like 0.18, 0.1532, 0.179 and 0.133 mg/l and the respective output concentrations were found to be 0.10, 0.1021, 0.11 and 0.09 mg/l. The concentrations of Iron were tested in the chemical testing laboratory under the Soil Resource Development Institute, Dhaka. The results have revealed that iron and arsenic content brings to allowable limit. The developed unit has the capacity to remove Arsenic and Iron and help to eradicates hazardous problem of people.
