http://orgprints.org/10311/ Indicators of weed competition on Organic Winter Wheat Casagrande, Marion David, Christophe Valentin Morison, Muriel Jeuffroy, Marie-Hélène Cereals, pulses and oilseeds Weed management Organic winter wheat production is limited by climatic and agronomic factors, including weed competition. The incidence of weeds on yield limitation can be characterized through various early indicators to predict weed occurrence and competition. A network of 10 fields of organic winter wheat was implemented in the South East of France in 2005-2006. Results showed that weed density, dynamics and diversity are good indicators for weed occurrence and competition. 2007 Conference paper, poster, etc. NonPeerReviewed application/pdf http://orgprints.org/10311/1/casagrande-etal-2007-winterwheat.pdf Casagrande, Marion; David, Christophe; Valentin Morison, Muriel and Jeuffroy, Marie-Hélène (2007) Indicators of weed competition on Organic Winter Wheat. 3rd QLIF Congress: Improving Sustainability in Organic and Low Input Food Production Systems, University of Hohenheim, Germany, March 20-23, 2007. http://orgprints.org/10311/http://orgprints.org/10311/1/
