Growth‐promoting diazotrophs can enhance the growth and development of associated crops by transferring fixed N or improving nutrient uptake through modulation hormone‐linked phenomena in inoculated plants. Six rhizobial isolated from a wide range legume hosts were investigated to determine their growth‐promoting activities lowland rice ( Oryza sativa L.) during 1997. Seeds seedlings Pankaj with different rhizobia grown potted soil supplemented varied amounts mineral N. Inoculation Rhizobium...
Rice ( Oryza sativa L.) is one of the world's most important crops. The present investigation was designed to assess range growth‐promoting activities various diazotrophic bacteria on rice seedling vigor, its carryover effect straw and grain yield, persistence an inoculant strain roots under greenhouse conditions. Growth responses inoculation exhibited bacterial strain–rice variety specificity that were either stimulatory or inhibitory. included changes in rates emergence, radical...
Understanding spatiotemporal variability in precipitation and temperature their future projections is critical for assessing environmental hazards planning long-term mitigation adaptation. In this study, 18 Global Climate Models (GCMs) from the most recent Coupled Model Intercomparison Project phase 6 (CMIP6) were employed to project mean annual, seasonal, monthly precipitation, maximum air (Tmax), minimum (Tmin) Bangladesh. The GCM bias-corrected using Simple Quantile Mapping (SQM)...
Tilapia farming has expanded rapidly in Bangladesh over the years thanks to a suitable climate for aquaculture and consistently increasing demand fish rich vitamins minerals. A clear picture regarding future trend of tilapia production is still not available, however. The purpose this study was estimate parameters that fit into Autoregressive Integrated Moving Average (ARIMA) model forecasting Bangladesh. This accomplished by calibrating validating ARIMA taking account lowest values Akaike...
Rainfall variability, waterlogging and frequent natural hazards are the major obstacles for cropping system intensification in heavy textured soils of coastal areas Bangladesh. While earlier monsoon rice harvesting by introducing short duration varieties created opportunities cultivating low water demanding non-rice crops dry season, such failed many instances because rainfall waterlogging. To address issue, we have analysed season (Nov–Apr) patterns six meteorological stations Bangladesh...
Information on carbon dioxide (CO2) emission from different organic sources and their temperature sensitivity to decomposition is scarce in Bangladesh. Therefore, this study quantified the rates of CO2 (C) degradation constants material mixed soils at variable temperatures two laboratory experiments. The first experiment was conducted room for 26 weeks C mineralization using vermicompost, chicken manure, cow dung, rice straw, husk biochar. Weekly measured by alkali absorption followed acid...
Decomposed organic materials, in combination with plant growth-promoting bacteria (PGPB), are environmentally friendly and reduce synthetic fertilizer use rice production. A bio-organic (BoF) was prepared using kitchen waste (79%), chita-dhan (unfilled grain) biochar (15%), rock phosphate (5%), a consortium of 10 PGPB (1%) to supplement 30% nitrogen replace triple superphosphate (TSP) production an improvement soil health. were local isolates identified 16S ribosomal RNA partial gene...
A study was conducted to assess the effects of organic amendments on soil aggregates, carbon (C) sequestration, and energy use efficiency (EUE) during five consecutive Boro Transplanted Aman rice seasons in Bangladesh 2018–2020. Five treatments (viz., control (only inorganic fertilizers), cow dung (CD), vermicompost (VC), straw (RS), poultry manure (PM)) were used. The materials applied at 2 t C ha−1 season−1 all plots, except treatment. Inorganic fertilizers both following integrated...
Urea deep placement (UDP) and the alternate wetting drying (AWD) irrigation method are two promising rice production technologies. However, studies on impact of UDP under AWD nitrous oxide (N2O) nitric (NO) emissions limited. In this study, effects with these emissions, nitrogen use efficiency (NUE), yields investigated, compared to conventional broadcast application. N2O NO from three fertilizer treatments - no nitrogen, UDP, application prilled urea (PU) were measured. Measurements taken...
The impacts of climate change (CC) on all spheres human life are evident worldwide. Fish is the premier protein source, and its production in Bangladesh mainly dependent hatchery-based seed production. However, hatchery productivity disrupted every year due to CC. This study assesses CC fish hatcheries from perspective owners. A semi-structured questionnaire survey was conducted with 60 owners five sub-districts (Trishal, Mymensingh Sadar, Gouripur, Fulbaria, Muktagacha) district, highest...
Rhizobial inoculation increases grain yield in rice ( Oryza sativa L.), a nonlegume plant, but little is known about the mechanism(s) involved. This study was conducted to determine whether with rhizobia could influence leaf photosynthesis of plants under greenhouse conditions. Rice seeds and pot soil were inoculated three rhizobial strains or without added N fertilizer. Single‐leaf net photosynthetic rates measured portable systems (LI‐6200 LI‐6400) at several growth stages. Stomatal...
Rice crops uptake large amounts of potassium (K), which is mainly supplied from inorganic fertilizer. Alternate K sources are essential to preserve natural reserves and recycle unused containing stubbles. We have evaluated the performance rice straw (RS) in farmers' field following integrated plant nutrient system (IPNS) for supplementing requirement compared with agro-ecological zone (AEZ)-based chemical fertilizer practice Tista Meander Floodplain soils Bangladesh during 2013–2015....
Abstract Appraisal of the long‐term precipitation trends and variability is crucial for sustainable water resources management. This research intended to evaluate Bangladesh's monthly, seasonal, annual spatiotemporal rainfall using 40 global climate models two representative concentration pathways (RCPs), RCP4.5 RCP8.5. Statistical downscaling model (SimCLIM) was used ensemble projection in near (2011–2040), middle (2041–2070), far (2071–2100) futures. Modified Mann–Kendall test applied...
Abstract Pumping groundwater for irrigation in Bangladesh is a major energy-consuming process and mostly depends on diesel fuel, which related to greenhouse gas (GHG) emissions. But that issue has not yet been addressed Bangladesh. `In this study, we have estimated GHG emissions dry season (DS) irrigated rice considering all devices with their lifting heads, area coverage, water sources (surface groundwater) power (diesel electricity) during 2019–2020. varied locations, of irrigation, fuel...
