False seedbeds in organic grown winter wheat [PDF]

open access: yes, 2009
The false or stale seedbed technique is known as an effective tool of integrated weed control espe-cially in winter crops. However, only little data are available on the additional false seedbed effect compared to the only effect of late ...

Specific interactions leading to transgressive overyielding in cover crop mixtures [PDF]

open access: yes, 2017
Growing mixtures of species instead of sole crops is expected to increase the ecosystem services provided by cover crops. This study aimed at understanding the interactions between species and investigating how they affect the performance of the mixture.

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

open access: yesPeople and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Sowing date, cultivars and plant density for second crop narrow row cotton

open access: yesPesquisa Agropecuária Tropical, 2015
The second crop narrow row cotton under rainfed conditions, after soybean or common bean harvest, has increased in the Midwest Brazilian Savannah. This change in sowing date exposes cotton plants to adverse environmental conditions.

Wheat breeding approaches for designing wheat to thrive in a warmer world

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper
