Can Soybean Seeding Rate Be Used as an Integrated Component of Herbicide Resistance Management?
Herbicide-resistant crops integrated weed management PRE residual herbicides weed competition
2015/12/21
Increased soybean seed cost has generated recent interest in reducing seeding rates to improve economic returns. However, low seeding rates result in reduced established plant stands with slower canop...
Prevalence of Tree Regeneration by Sprouting and Seeding Along a Rainfall Gradient in Hawai’i
feral pig disturbance Sus scrofa tropical dry forest tropical wet forest
2015/11/13
Drought stress in tropical dry forests is thought to result in greater asexual regeneration via vegetative sprouting (e.g., basal, root, and branch layering) than occurs in
moister tropical forests. ...
Quantitative and qualitative damage caused by mammals and birds to the planting and natural seeding
woody plants damage mammals birds
2015/1/29
In the years 1999–2000, I studied damage to transplants in the planting and wildlings in the natural seeding at the locality Zamrlô in the Starohorské vrchy Mts. (750–1,000 m a.s.l., NE exposure,...
Grassland Response to Herbicides and Seeding of Native Grasses 6 Years Posttreatment
