Commonly used herbicides, such as sulfentrazone, pose the risk of soil contamination due to their persistence, bioaccumulation and toxicity. Phytoremediation by green manure species has been tested using biomarkers, but analytical data are now required to confirm the extraction of sulfentrazone from soil. Thus, the present work was carried out to analyze sulfentrazone residues in soil based on ...
Common bean (Phaseolus vulgaris L.) can establish symbiotic associations with several Rhizobium species; however, the effectiveness of most strains at fixing nitrogen under field conditions is very low. PRF 81(T) is a very effective strain, usually referred to as Rhizobium tropici and used successfully in thousands of doses of commercial inoculants for the common bean crop in Brazil; it has sho...
The Bradyrhizobium sp. DOA9 strain isolated from a paddy field has the ability to nodulate a wide spectrum of legumes. Unlike other bradyrhizobia, this strain has a symbiotic plasmid harboring nod, nif, and type 3 secretion system (T3SS) genes. This T3SS cluster contains all the genes necessary for the formation of the secretory apparatus and the transcriptional activator (TtsI), which is prece...
Crop Performance Indexes Applied to Legume Used as Summer Cover Crops under Water Deficit Conditions
Summer legume cover crops (CC) such as Crotalaria juncea, spectabilis, ochroleuca, and Cajanus cajan could offer diverse advantages for the environment productive cropping systems. A low transpiration efficiency (TE) of CC can induce soil water content to levels that present a challenge subsequent crop. In 75-day growth chamber experiment, using natural abundance 13C, 18O, 15N we evaluated TE B...
