Key planting factors that influence corn stand establishment includes uniform depth and spacing of seed, correct seed population and optimizing the soil environment for rapid germination and uniform emergence. Other variables affecting stand establishment are seedbed quality (including soil moisture and temperature), seed quality and planter speed. Differences among fields for stand establishme...
Seed dressing, i.e., the treatment of crop seeds with insecticides and/or fungicides, aiming to protect seeds from pests and diseases, is widely used in conventional agriculture. During the growing season, those crop fields often receive additional broadband herbicide applications. However, despite this broad utilization, very little is known on potential side effects or interactions between th...
Restoration of coastal plain depressions, a biologically significant and threatened wetland type of the southeastern United States, has received little systematic research. Within the context of an experimental project designed to evaluate several restoration approaches, we tested whether successful revegetation can be achieved by passive methods (recruitment from seed banks or seed dispersal) ...
The relationship between acid soils and (1) early nodulation in common beans, (2) interstrain competitiveness of Rhizobium leguminosarum bv. phaseoli strains and (3) tannin concentration in roots, were evaluated in two experiments. Ten Phaseolus vulgaris cultivars of different seed tannin content were grown in pots in a greenhouse in soil at pH 4.5 or 5.5, inoculated with equal amounts of strai...
Abstract Regeneration of tropical forest occurs naturally and mainly through early secondary succession by soil seed banks. Here, we analyzed bank variation in density diversity along a degradation gradient. We also explored the relationship (similarity composition) between seedling banks overstory vegetation. The investigated forests were located at Dja Fauna Reserve its surroundings, south‐ea...
Soil seedbanks drive infestations of annual weeds, yet weed management focuses largely on seedling mortality. As weed seedbanks increasingly become reservoirs of herbicide resistance, species-specific seedbank management approaches will be essential to weed control. However, the development of seedbank management strategies can only develop from an understanding of how seed traits affect persis...
