Irrigation application and organic amendments could contribute to the improvement of wheat production in coastal areas. Field experiment was carried out at Shamnagar, Satkhira Sadar for the improvement of wheat production in saline areas through irrigation application and gypsum amendments. Two wheat cultivars viz. L-880-43 and BARIghom- 26 were used as test crops. There were six treatments such as control (no irrigation); one irrigation at vegetative stage with canal water (canal water means rainwater harvested in natural/man-made canal); one irrigation at vegetative stage with STW water + Gypsum application @ 200 Kg/ha (STW means sallow tube-well); Irrigation at vegetative and heading/flowering stage with canal water; Irrigation at vegetative stage with saline canal water + Gypsum application @ 200 Kg/ha; Irrigation at vegetative and heading/flowering stage with STW water + Gypsum application @ 200 Kg/ha. The treatments were allocated in the main-plot and the cultivars in the sub-plot all experimental plots received recommended doses of urea, triple super phosphate, and muriate of potash. The treatments were imposed accordingly. The results showed that soil salinity caused a significant reduction in growth and yield components of both wheat cultivars. Irrigation application and Gypsum amendments significantly increased the growth and yield components of both cultivars under soil salinity. Soil salinity also reduced grain yields of both cultivars. Combined application of irrigation water and gypsum amendments showed higher yields than that of sole application of irrigation water during saline conditions. Gypsum used as amendments because it reduces the soil salinity. Therefore, the present study suggests that wheat production might be feasible in coastal areas of southern Bangladesh (saline soils) through irrigation application and gypsum amendments. Res.

Aims: Rice is the most widely consumed staple food as well as Bangladesh. With the global upsurge in population, rapid urbanization, and industrialization increasing waste production in urban areas and managing them becoming a major concern. Municipal solid waste (MSW) is considered an important recycling tool for use in agricultural fields as compost. Green manure (GM) is another thing thatprovides a substantial portion of the nitrogen requirement of rice. Both MSW compost and GM add organic matter to the soil. We conducted a study to know the residual effects of municipal solid waste (MSW) compost and green manure (GM) on nutrient contents in soil and uptakes in rice (BINA Dhan-7). Methods: The experiment was conducted with a Randomized Complete Block Design (RCBD), nine treatments, and three replications. The present rice crop received no fertilizers during the cultivation period. MSW compost and GM inoculated with Rhizobium strains were incorporated as per treatments in 2 cycles of the Mungbean- Dhaincha- Rice cropping pattern. Results: The highest nutrient content and uptake were recorded with higher rates of MSW compost and GM application in the preceding crops. Compost is a slow-release source of nitrogen and most nitrogen remaining after completion of the composting process is bound into organic forms. After application nutrients do not become available immediately for plant uptake, and remain as residue which contributes to improving soil quality for several years after application ceases. MSW compost and GM increases soil nutrient contents, availability, and uptake by adding organic matter, increasing the C: N ratio, and soil’s physical, chemical, and biological properties. Conclusion: The MSW compost and GM can provide a significant amount of residual effects on the nutrient content in the soil and uptake in rice which depends on the nutrient composition of applied manure in previous crops.
Background: The proportion of Diabetes is becoming more aggregate around the universe, and it is linked to both genetic and environmental causes. Because of the rising prevalence of type 2 diabetes among young people, the number of pregnancies with this problem has increased. Objectives: The aim of the study was to assess the proportion of Gestational Diabetes Mellitus (GDM) among the pregnant mothers and their socio-demographic characteristics.
