Abstract Field studies were conducted in 2021 Kibler and Augusta, AR, to determine the effect of winter cover crops cultivar selection on weed suppression sweetpotato [ Ipomoea batatas (L.) Lam.] yield. The split-split-plot evaluated three [cereal rye ( Secale cereale L.) + crimson clover Trifolium incarnatum L.)], [winter wheat Triticum aestivum clover], fallow; weeding (with or without); four...

The effects of cover crops on the biology soybean cyst nematode (SCN; Heterodera glycines) are not well established. It is possible that may reduce SCN population densities by acting as trap crops. Cover with potential to serve stimulate hatching and/or attract hatched juveniles and also be penetrated large numbers nematodes cannot feed. Experiments were conducted determine whether root exudate...

Legume cover crops are central to an ecological nutrient management approach that can reduce nitrogen (N) losses from agriculture. Diversifying cropping systems with a legume–grass crop mixture could further N by increasing soil assimilation and synchronizing mineralization uptake the following crop. We established four winter treatments (crimson clover, cereal rye, clover–rye mixture, weedy fa...

Little data exists on cadmium (Cd) accumulation in many plant species now commonly used as animal forages in New Zealand livestock grazing systems. A glasshouse trial was undertaken on 12 forage species to address this knowledge gap. Mean tissue Cd concentration decreased in the order chicory > plantain > turnip > lucerne > sheep’s burnet > strawberry clover > kale > perennial ryegrass > haresf...

Fluorescent proteins (FPs) with far-red excitation and emission are desirable for multicolor labeling and live-animal imaging. We describe E2-Crimson, a far-red derivative of the tetrameric FP DsRed-Express2. Unlike other far-red FPs, E2-Crimson is noncytotoxic in bacterial and mammalian cells. E2-Crimson is brighter than other far-red FPs and matures substantially faster than other red and far...

The inclusion of undersown cover crops in crop rotations and the use biopesticides are essential for long-term sustainability agroecosystem organic farming. We hypothesized that (crimson (incarnate) clover (Trifolium incarnatum Broth.), hairy (winter) vetch (Vicia villosa Roth.), perennial ryegrass (Lolium perenne L.), winter rye (Secale cereale L.)) likely to have a positive impact on soil agr...

Current environmental concerns, the rising economic and costs of mineral fertilizers need to respond limitations N fertilization in organic farming motivate search for alternative sources maize cropping. Forage legumes used as winter cover crops may improve soil fertility offer benefits environment. The aim this study was examine effects, a factorial field experiment, two sowing dates (SD) nine...
