The increasing popularity of reduced tillage on crops has not only been an important development in combating soil erosion, but it has also been associated with increasing organic material and producing high crop yields.
For peanut crops, however, reduced tillage has not gained a large acceptance as a viable practice, as findings of inconsistent yields have not encouraged farmers to make a switch from conventional tillage systems.
New research study was conducted on the effects of tillage systems and crop rotation on peanut yield and pest development in the crops. The study, conducted at North Carolina State University, was recently published in Agronomy Journal, and was funded in part by the North Carolina Peanut Growers Association and the National Peanut Board.
The study found that there is an independent relationship between tillage and rotation practices with respect to peanut yield and pest development. The research began in 1999 and 2000 at two locations that used various crop rotations, including corn, cotton, and peanut, and a comparison was made between conventional tillage versus strip tillage into stubble from the previous crop stubble.
“The primary objective of this research was to determine interactions of crop rotations and tillage systems with respect to peanut,” said David Jordan, the principle researcher for the project. “Although differences in peanut yield were associated with crop rotation and tillage system, these data suggest that while farmers should expect some differences in peanut yield due to rotation and tillage, response to these management practices most likely will be independent.”
The study did find that the tillage system used did have an effect on the development of tomato spotted wilt, a disease common in southern growing states. Additionally, the research also determined that the most effective method found to increase crop yield and manage pests is to increase the number of years between peanut plantings.
Research continues to be conducted at North Carolina State University comparing crop rotation and tillage systems and possible relationships between these important aspects of cropping systems in the southern United States. According to the author, additional research is needed in other geographical regions to study alternative crops, soil characteristics, and other pest complexes.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
