Propionate-forming bacteria seem to be abundant in anoxic rice paddy soil, but biogeochemical investigations show that propionate is not a correspondingly important intermediate in carbon flux in this system. Mixed cultures of Opitutus terrae strain PB90-1, a representative propionate-producing bacterium from rice paddy soil, and the hydrogenotrophic Methanospirillum hungatei strain SK maintain...

Microplot experiments on flooded soil infested with Hirschmanniella oryzae were conducted to investigate the influence of the legum Sesbania rostrata as a rotat ion crop with rice, Oryza sativa L. cv. Moroberekan. To avoid a green manure effect f rom S. r'ostrata, all aerial parts were removed at harvest. The dry weight of paddy, culms and leaves, and n u m b e r of culms of rice following Sesb...

Rice is the major source of food for half of the world’s population. Paddy production entails use of costly resources a quarter to one third of world’s annual fresh water supply, fossil fuels and synthetic fertilizers leading to high ecological foot prints. Paddy fields also emit greenhouse gases to global warming, soil and water pollution. The system of Rice Intensification (SRI) is an answer ...

BACKGROUND Program effectiveness is influenced by the degree and quality of implementation, thus requiring careful examination of delivery processes and how the program is or is not being implemented as intended. Implementation fidelity is defined by adherence to intervention design, exposure or dose, quality of delivery, and participant responsiveness. As part of the process evaluation (PE) of...

This study was undertaken to assess the socio-economic impact of producing export oriented agricultural crops on the livelihoods of the farmers, in eastern Ethiopia. A random sample of 305 farmers was studied. Comparisons were made between producers and non-producers using the Ztest and regression analysis. It was found that producers of export oriented crops are better off than the non-produce...

OBJECTIVE The objective of this study was to examine the predictive relationships between employee health risk factors (HRFs) and workers' compensation (WC) claim occurrence and costs. METHODS Logistic regression and generalised linear models were used to estimate the predictive association between HRFs and claim occurrence and cost among a cohort of 16 926 employees from 314 large, medium an...

An anammox assay involving a ¹⁵N tracer and gas chromatography-mass spectrometry revealed that the potential anammox activity accounted for 1 to 5% of total N₂ production in a ravine paddy field, Japan. Among four 4-cm-deep layers, the top layer showed the highest activity. Clone libraries showed that the DNA in the top layer contained sequences related to those of Candidatus 'Brocadia fulgida'...
