Biochar with nitrapyrin reduces ammonia volatilization and increases nitrogen use efficiency of cabbage: A 15N tracer study
Nitrogen use efficiency (NUE) in subtropical crop** systems is low causing a large quantity of reactive N loss to the environment. However, the mechanisms and pathways of such losses are poorly understood. T...

Conservation agriculture improves yield and potassium balance in intensive rice systems
Intensive rice-based systems are mining soil potassium (K) due to negative K balances. Conservation Agriculture (CA) practices may increase yield and economic return of rice-based systems but there is limited ...

Tillage and Residue Management Impact on Microbial and Nematode Abundance Under Diverse Rice-Based Crop** Systems in Calcareous and Non-calcareous Floodplain Soils
Switching from conventional to conservation agriculture (CA) practices may affect the soil microbial community; however, such information in rice-based systems is yet to be explored. Two field experiments were...

Article
Conservation agriculture in intensive rice crop** reverses soil potassium depletion
Intensive crop** in the Eastern Gangetic Plain has progressively depleted soil potassium (K) over time due to negative K balances. There is limited understanding of how alternative soil and crop management p...

Effect of Bioslurry on the Yield of Wheat and Rice in the Wheat–Rice Crop** System
The study was conducted to assess the integrated use of chemical fertilizers with organic manure in the wheat–rice crop** systems in Bangladesh. The experiment involved a sole chemical fertilizer treatment, ...

Article
Nitrous oxide and nitric oxide emissions and nitrogen use efficiency as affected by nitrogen placement in lowland rice fields
Urea deep placement (UDP) has demonstrated its benefits of saving N fertilizer and increasing nitrogen use efficiency (NUE) and grain yields. However, studies on its environmental impacts, particularly on nitr...

Floodwater ammonium, nitrogen use efficiency and rice yields with fertilizer deep placement and alternate wetting and drying under triple rice crop** systems
Fertilizer management should consider optimum time, rates and methods of application to increase use efficiency and crop yield. We conducted field experiments at Bangladesh Agricultural University, Bangladesh,...

Accumulation of arsenic in soil and rice under wetland condition in Bangladesh
Shallow tube well (STW) water, often contaminated with arsenic (As), is used extensively in Bangladesh for irrigating rice fields in the dry season, leading to potential As accumulation in soils. In the curren...

Article
Fate of irrigation-water arsenic in rice soils of Bangladesh
An experiment involving four soils and three irrigation-water As concentrations was conducted in undisturbed soil columns during 2004–2006, with Boro (winter dry-season, flood-irrigated rice, using As-contaminate...

Article
The effects of iron plaque and phosphorus on yield and arsenic accumulation in rice
The effects of arsenate, Fe2+, and phosphate on amount and composition of Fe-oxide plaque at the rice-root surface and on the yield and arsenic accumulation in rice (cv. BRRI dhan33) were studied in a replicated ...

The requirement of zinc for improvement of crop yield and mineral nutrition in the maize–mungbean–rice system
A study was made over 3 years to find out an optimum rate of Zn application for the maize–mungbean–rice crop** system in a calcareous soil of Bangladesh. Zinc application was made at 0, 2 and 4 kg ha−1 for maiz...

Chapter and Conference Paper
Boron Nutrition and Boron Application in Crops
Boron deficiency is a major reason for lower yield of wheat and mustard in Bangladesh. This element deficiency has arisen mainly due to continuous mining of soil nutrients for increased crop** intensity with...

Boron Efficiency in a Wheat Germplasm from Bangladesh
Wheat production in Bangladesh has grown from about 32,000 tons from 60,000 ha in 1961 to almost 2 million tons from 800,000 ha by the year 2000. Wheat has contributed significantly to the country’s food secur...

Enrichment of indigenous blue—green algal population in rice fields and evaluation of its effect in rice culture
A field experiment was carried out at Bangladesh Agricultural University Farm, Mymensingh during the 1992 boro season to enrich the indigenous blue—green algal population and to evaluate its effectiveness in r...
