Tillage, Rotation Impacts Peanut Crops

11.11.2008
A new study in Agronomy Journal shows the differing effects of tillage practice and rotation on peanut crop yield and the development of pests.

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.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
