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: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
