UNIVERSITY OF ILLINOIS - NOV 2019 - The State of Soybean in Africa: Evaluating the Benefits of Implementing Soy-Maize Crop Rotations. AGRONOMY 04/12/19 Conservation Agriculture Improves Long-term Yield and Soil Quality in Irrigated Maize-oats Rotation. Conservation agriculture, characterized by minimal tillage, permanent soil cover and crop diversification, has been widely adapted under rainfed conditions, but adoption under irrigated conditions is limited.

AGRONOMY 04/12/19 Conservation Agriculture Improves Long-term Yield and Soil Quality in Irrigated Maize-oats Rotation

An experiment initiated in 1997 to evaluate the level of tillage and the amount of soil cover needed for conservation agriculture to work under irrigated conditions in the highlands of San Luis Potosí, Mexico. The trial encompassed seven treatments: conventional tillage, two types of reduced tillage and permanent raised beds (PB), which are untilled, with four levels of soil cover in an irrigated rotation with maize (Zea mays L.) in the summer and fodder oats (Avena sativa L.) in the winter. Maize and oats yielded significantly more under PB than with tillage. Maize yielded on average 1.2 Mg ha−1 more in PB with the hybrid used from 1997 to 2008 and 3.9 Mg ha−1 more with the hybrid used from 2012 to 2017. ►▼ Show Figures Figure 1.

Low prices have prompted growers to contemplate transitioning to an organic system.

Proc Natl Acad Sci U S A. 2013 Jul 16;110(29):11917-22. Gut bacteria facilitate adaptation to crop rotation in the western corn

Gould, North Carolina State University, Raleigh, NC, and approved May 24, 2013 (received for review January 29, 2013) Abstract Insects are constantly adapting to human-driven landscape changes; however, the roles of their gut microbiota in these processes remain largely unknown. The western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte) (Coleoptera: Chrysomelidae) is a major corn pest that has been controlled via annual rotation between corn (Zea mays) and nonhost soybean (Glycine max) in the United States.

Metagenomic studies are accelerating our understanding of host–microbe associations in various organisms; many microbial symbionts contribute directly to host evolution (1⇓⇓–4). Throughout the US Corn Belt, annual crop rotation between corn (Zea mays) and soybean (Glycine max) is practiced to control the WCR (6, 7).

PASSERELLE ECO - SEPT 2011 - Chrysomèle : la rotation des cultures est incontournable

Dans les cultures industrielles, reconduites chaque année à coup d’engrais, d’arrosages et de pesticides, elle s’en donne à coeur joie. L’industrie biotechnologique, toujours à l’affut des manques, y voit l’opportunité de pousser ses produits transgéniques. Pourtant ce n’est pas une solution : les chrysomèles s’adaptent, des résistances apparaissent déjà.

MORNINGAGCLIPS 11/03/20 Rotating crops over time boosts corn yields, even in droughts - UNH, Berkeley Research Shows Crop Diversification is Effective Response to Climate Change

(Credit: Tim Bowles/UC Berkeley) DURHAM, N.H. – Rotating crops over time increases the yield of corn, even during unfavorable weather conditions such as droughts, according to new research findings from the NH Agricultural Experiment Station at the University of New Hampshire and the University of California, Berkeley. The findings demonstrate that diversifying crops may be an effective, long-term strategy for strengthening food production systems globally in the face of a changing climate and environmental degradation. “The trend towards fewer crops in our agroecosystems is alarming, with massive amounts of U.S. land dedicated to producing corn year after year, or rotating corn one year with soybean the next.

The research is presented in the recent issue of the journal One Earth (DOI: 10.1016/j.oneear.2020.02.007).
