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...

Abstract: Soybean [Glycine max (L.) Merr.] represents one of the most essential crops to world’s economy and food security due its unique seed composition. Public soybean breeding programs in United States played an important role developing genetic basis American discovering many economically traits. After passage Plant Variety Protection Act (PVP) 1970 authorization patent living matter 1980,...

Crop yield and economic profitability, both highly dependent on local crop management, soil characteristics, weather conditions, are among the most influential factors to consider when considering a cropping system. The objective of this study was compare returns three different 4-yr diverse rotations with that 2-yr traditional rotation in eastern South Dakota. included were (a) corn (Zea mays ...

low phosphorous (p) availability in soils limits production of soybean [glycine max (l.) merr.] around the world. this study was conducted to determine whether exogenous expression of the rice (oryza sativa l.) phosphates transporter gene ospt2 would increase inorganic phosphates (pi) acquisition and improve yield in transgenic soybean. cotyledonary-node explants of the soybean were inoculated ...

This study was conducted to determine by gas chromatography (GC) and mass spectrometry (MS) the identity and the quantity of volatile N products produced during the helium-purged in vivo NR assay of soybean (Glycine max [L.] Merr. cv Williams) and winged bean (Psophocarpus tetragonolobus [L.] DC. cv Lunita) leaflets. Gaseous material for identification and quantitation was collected by cryogeni...

Bacterial communities in rhizosphere and root nodules have significant contributions to the growth productivity of soybean (Glycine max (L.) Merr.). In this report, we analyzed physiological properties dynamics bacterial community structure at different stages using BioLog EcoPlate high-throughput sequencing technology, respectively. The assay found that metabolic capability is increasing trend...

Soybean (Glycine max (L.) Merr.) is one of the most economically important crops in world due to its nutritional value. To optimize soybean growth and yield, a wide range commercial herbicides intended for weed control are used. Although used selective, they can still cause oxidative stress disturb photosynthetic reactions crops. In this work, influence selective on efficiency antioxidative res...

Environmental risk assessment is required for genetically modified (GM) crops before their import into Japan. Annual roadside monitoring along transportation routes from ports to processing facilities for GM soybean (Glycine max (L.) Merr.) have been requested as a condition of import only approval because of lack of information on the likelihood of persistence of imported GM soybean for food, ...

The biochemical and nutritional attributes of two soybean (Glycine max (L.) Merr.) cultivars, one susceptible (Seridó) and the other resistant (Seridó-RCH) to stem canker, were examined to assess whether the resistance to pathogens was related to levels of antinutritional and/or defense proteins in the plant and subsequently affected the nutritional quality. Lectin, urease, trypsin inhibitor, p...

abstract soybean (glycine max) is an important crop plant which contains a high amount of oil and protein. to evaluate the genetic diversity of 45 soybean genotypes growing in iran, two types of molecular markers (rapd and isj) were used. two sets of different primers were used to compare potential differentiation power of it (intron targeting) and et (exon targeting) primers. data obtained fro...
