Impact of System of Rice Intensification (SRI) Components on Nutrient Content, Nutrient Uptake, Soil Parameters and Economics over Conventional Puddled Transplanted Rice

The Effects of Repeated Soil Wetting and Drying on Lowland Rice Yield with System of Rice Intensification (SRI) Methods

In lowland rice farming, water control is the most important management practice that determines the efficacy of other production inputs such as nutrients, herbicides, pesticides, farm machines, microbial activity, mineralization rate, etc. Poor drainage that keeps soil saturated is detrimental to crops and degrades soil quality. In many rice irrigation systems, drainage mechanisms and practice...

Effects of Soil pH and Eh on Growth and Nutrient Uptake by Rice in a Flooded

Rice grown on a flooded Sumatra Oxisol soils frequently exhibits poor growth and low yield. A study has been made of the effects of pH and redox conditions on growth and nutrient uptake by rice, and the relationship between nutrient release in the flooded soil and nutrient uptake by the rice plant. At pH 4.5 rice plants produced low plant height, low root dry weight, low shoot dry weight, slow ...

Effect of System of Rice Intensification (SRI) on rice yield in Bangladesh, Boro Season, 2005-2006

In an on-going effort of the FoSHoL project of ActionAid Bangladesh to evaluate the farmers’ perception and effect of system of rice intensification on the yield, 85 farm families of Tala, Satkhira Sadar, Biswamvampur, Noakhali, Ulipur and Koira Upazilla of Satkhira, Sunamganj, Noakhali, Kurigram and Khulna districts conducted the study in their own lands in a participatory action research appr...

Effects of arsenic and moisture regime on nutrient content and their uptake by NERICA rice

A pot experiment was carried out in the net house of Bangladesh Institute of Nuclear Agriculture (BINA) to study nutrient content and their uptake by different rice varieties (NERICA-1, NERICA-10 and BRRI dhan48) in response to different levels of arsenic (As) under varying moisture regimes. Three levels of As were added viz. 0, 30, 60 ppm to the pot soil from sodium arsenate (Na2HAsO4. 7H2O). ...
