Barnyardgrass (Echinochloa spp.) is one of the most common and troublesome weeds in paddy rice cultivation. For effective barnyardgrass control, herbicides with high efficacy against the weed and good selectivity for rice are required. 1-Phenyl-5(4H)-4-dialkylcarbamoyltetrazolinones exhibited high activity against barnyardgrass in paddy field experiments. Fentrazamide, 4-(2-chlorophenyl)-N-cycl...

Because excised, washed roots of rice (Oryza sativa) immediately produce CH4 when they are incubated under anoxic conditions (P. Frenzel and U. Bosse, FEMS Microbiol. Ecol. 21:25-36, 1996), we employed a culture-independent molecular approach to identify the methanogenic microbial community present on roots of rice plants. Archaeal small-subunit rRNA-encoding genes were amplified directly from ...

Most paddy rice in the world grows in warm, humid and rainy environment where it is hard to acquire optical remote sensing data. Synthetic Aperture Radar (SAR) can acquire remote sensing information due to its all weather imaging and frequent revisit capability in the areas. A semi-empirical backscattering model was used to estimate leaf area index (LAI) from ENVISAT ASAR (Advanced Synthetic Ap...

Rice seedlings were inoculated with Azospirillum sp. B510 and transplanted into a paddy field. Growth in terms of tiller numbers and shoot length was significantly increased by inoculation. Principal-coordinates analysis of rice bacterial communities using the 16S rRNA gene showed no overall change from B510 inoculation. However, the abundance of Veillonellaceae and Aurantimonas significantly i...

Rice-duck farming system is one of the means of organic rice farming, in which the weeds, diseases and insects could be effectively controlled with minimal or no pesticide and herbicide application. Whereas in conventional rice-duck farming system the controlling effect on diseases, insect pests and weeds was slowly disappeared after the rice heading stage at which ducks were driven out of the ...

Urban land has increasingly expanded and encroached upon a significant number of paddy fields in Hang-Jia-Hu Plain, due to the rapid socio-economic development and agro-pedoclimatic conditions favorable to rice cultivation and human settlement. Although many studies have analyzed the characteristics of urban land expansion, relatively less attention has been paid to exploring the various urban ...

Rice provides the staple food for over 60% of the world’s population. Globally 80% of rice is grown by small farmers in low income and developing nations, and in India rice farming is a key source of employment for the 60% of Indian workers still dependent on agriculture for work. Yet rice production is also an important source of greenhouse gas emissions, for example responsible for between 3 ...

The efficiency of brown rice and germinated brown rice as a substrate for probiotic food was investigated. Lactobacillus isolated from goat milk was used for fermenting the rice medium. Brown rice (BR) obtained by dehulling the paddy, was germinated for 48 h. The dried powders of BR and Germinated BR (GBR) were compared for the growth of Lactobacillus sp. and nutritive evaluation such as carboh...
