Abstract Soybean ( Glycine max L ) is a legume rich in protein, fat, vitamins, minerals and fibre. The nutritional value of soybeans the amino acid profiles processed fermented soybean (Tempe) products need to be studied. Tempe flour from black soybean, local (Anjasmoro variety) imported (USA soybean) were analyzed proximately, including carbohydrates (spectrophotometric method), protein (Kjeld...

The phenomenon that rhizosphere processes significantly control soil organic matter (SOM) decomposition, also termed rhizosphere priming effect (RPE), is now increasingly recognized as significant as the effects of soil temperature and moisture on SOM decomposition. However, the exact mechanisms responsible for RPE remain largely unknown. Particularly, some reports have suggested that the quali...

The effects of no-tillage (NT), conventional tillage (CT), and crop rotation on soybean yield and population dynamics of Heterodera glycines were compared during a 7-year study in a silty clay loam soil with 6% organic matter. Either H. glycines-resistant 'Linford' soybean or susceptible 'Williams 82' soybean was rotated with corn and grown on 76-cm-wide rows in both tillage systems. Soybean wa...

rotation is also more effective in preventing deep leaching of nitrate N than continuous corn (Katupitiya et al., Reduced tillage, including no-till, and crop rotation are common 1997; Varvel and Peterson, 1990). Reduced stress from practices for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production in the Midwest. Benefits of no-till vary with latitude pests may be one of the reas...

We evaluated the effects of the amount and type of C compounds (labile/recalcitrant) of crop residues on the soil organic matter (SOM) components under no-tillage practices in semiarid region of Argentina, with the aim of establishing criteria for sustainable agriculture. Five agricultural situations were evaluated: soybean/wheat rotation (wheat crop and at bare fallow); soybean monoculture; so...

Continuous rain and an abnormally wet climate during harvest can easily lead to soybean plants being damaged by field mold (FM), which can reduce seed yield and quality. However, to date, the underlying pathogen and its resistance mechanism have remained unclear. The objective of the present study was to investigate the fungal diversity of various soybean varieties and to identify and confirm t...

Western corn rootworm (Diabrotica virgifera) (WCR) depends on the continuous availability of corn. Broad adoption of annual crop rotation between corn (Zea mays) and nonhost soybean (Glycine max) exploited WCR biology to provide excellent WCR control, but this practice dramatically reduced landscape heterogeneity in East-central Illinois and imposed intense selection pressure. This selection re...

Cover crop growing periods in the western U.S. Corn Belt could be extended by planting earlier. We evaluated both pre-harvest broadcast interseeding and post-harvest drilling of following cover crops: (a) cereal rye (Secale cereale L.) [RYE]; (b) a mix + legumes brassicas [MIX1], (c) oat [Avena sativa L.] (MIX2), (d) [LEGU]) (e) no control. These were tested continuous corn (Zea mays [corn–corn...

The United States is the largest producer of maize in the world. Maize-soybean is the most prominent crop rotation in the Midwestern United States. Glyphosate-resistant volunteer maize is a problem weed not only in soybean, but also in continuous maize or sugarbeet rotations. Storm damage, harvesting problems, poor stalk quality, and insect damage, among other factors, can lead to kernel and ea...
