No persistent changes in pasture vegetation or seed bank composition after fallowing

The practice of fallowing pastures during the growing season is intended to increase plant diversity and allow natural reseeding of forage grasses. Fallowing delivers these benefits in New Zealand, but has been adopted on rotationally stocked farms in the northeastern United States with little or no quantitative assessment. Allowing the pasture to remain ungrazed may allow weedy species to ...

Soybean seed yield and composition response to stand reduction at vegetative and reproductive stages

Soybean [Glycine max (L.) Merr.] producers across the United States are confronted with significant economic losses annually from hail. Plant injury and yield loss are associated with defoliation and node or stand loss due to bruising and breaking of plant stems from the hail. The correlation of yield loss and leaf defoliation is well defined; however, limited information exists relative to whole ...

Soil seed bank composition in pastures of diverse mixtures of temperate forages

Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

Main-stem node removal effect on soybean seed yield and composition

Hail injury to soybean [Glycine max L. (Merr.)] is common across the United States. Currently, U.S. hail adjusters use procedures that assume that yield reductions caused by stem cutoff and defoliation or defoliation without stem loss is similar during the vegetative development period. Our hypothesis was that seed yield will be affected by timing of node removal in vegetative soybean and that ...

Self-seeded cereal cover crop effects on interspecific competition with corn

Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereal cover crops were planted in varying row spacing configurations and ...

Effect of seeding rate and planting arrangement on rye cover crop and weed growth

Weed growth in winter cover crops in warm climates may contribute to weed management costs in subsequent crops. A 2-yr experiment was conducted on an organic vegetable farm in Salinas, California, to determine the impact of seeding rate and planting arrangement on rye (Secale cereale L. ‘Merced’) cover crop growth and weed suppression. Each year, rye was planted in October at three rates (90, ...

How three U.S. mini-farms are sowing the seeds of global food security

Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

Mapping and comparison of quantitative trait loci for oleic acid seed content in two segregating soybean populations

Soybean [Glycine max (L.) Merr.] produces 29.4% of the world's edible vegetable oil. An important determinant of the nutritional value and the oxidative stability of soybean oil is the oleic acid content. Elevation of the oleate content levels leads to the improvement of soybean oil quality. However, our knowledge of the genetic factors underlying oleate variation in soybean seeds remains ...

Canopy nitrogen reserves: impact on soybean yield and seed quality traits in northern latitudes

Soybean [Glycine max (L.) Merr.] seed produced in the upper Midwest of the United States is lower in protein concentration than soybean produced throughout much of the Corn Belt, the southern United States, and Brazil. As protein comprises on average more than 400 g kg–1 of the soybean seed, yields in northern latitudes may be limited by seed protein accrual. Our objective was to examine the role ...
