Chemical Profiles of <i>Heterodera glycines</i> Suppressive Soils in Double Cropping Soybean Production

چکیده
Abstract We previously reported soybean fields double-cropped with winter wheat having reduced cyst nematode (SCN) ( Heterodera glycines ) counts compared to fallow. A follow-up metagenomics study identified several fungal and bacterial taxa enriched in fields, some were parasitize SCN. Knowing that phytocompounds potential nematicidal activity are released via roots stubble, we implemented a dichloromethane-based extraction method gas chromatography-mass spectrometry (GCMS) system investigate soil chemical profiles of samples collected from these review the compounds higher concentration double cropping fields. 51 detected during GCMS analysis, eight unknown identification. Several compounds, including multiple fatty acids, had larger relative peak areas when double-cropped, fallow samples. This study, along our published one, provided better understanding mechanisms govern effect on SCN populations. Rather than driven by single mechanism, suppression was potentially linked microbial communities, increased populations beneficial organisms, concentrations chemicals activity. To knowledge, this is first using characterize regarding

Effect of tillage and residue management on productivity of soybean and physico-chemical properties of soil in soybean–wheat cropping system
A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...

Influence of sustainable agricultural practices on chemical properties of vertisol soil with Soybean-Wheat cropping sequence
The present study is one step towards sustainable agricultural practices. The results observed for chemical properties like pH, electrical conductivity, available nitrogen, available phosphorus, available potassium, available sulphur, zinc content, organic carbon content and organic matter of vertisol soil indicated that these properties were significantly enchanced at different stages of Soybe...

Progress in next-generation sequencing has played a significant role in ecological studies of microbial populations. These advances have led to a rapid evaluation in metagenomics studies (analysis of DNA of microbial communities without the need to culture). Many statistical and computational tools and metagenomics databases have led to the discovery of huge amounts of data. In this research, i...
