Última Nitrogen fixation and yield of lucerne (Medicago sativa L.), as affected by co-inoculation with Sinorhizobium meliloti and arbuscular mycorrhiza under dry organic farming conditions Organic Eprints Ardakani, M.Reza; Pietsch, Gabriele; Wanek, Wolfgang; Schweiger, Peter; Moghaddam, Ali; Friedel, Juergen K.. This study evaluated the effects of co-inoculation with Sinorhizobium meliloti and arbuscular mycorrhizal fungi on the growth, yield and biological nitrogen fixation (BNF) of lucerne (Medicago sativa L.) under organic farming and dry weather conditions. The trial was laid out as a factorial experiment in the fields of the University of Natural Resources and Applied Life Sciences, Vienna-Austria at Raasdorf in 2007. The experimental factors of S. meliloti and arbuscular mycorrhiza (AM) including Glomus etunicatum, G. intraradices and G. claroideum and irrigation levels were tested. Co-inoculation of lucerne with S. meliloti and AM increased shoot dry weight as well as BNF at the first and second harvest but for BNF it was not significant. Irrigation...

The below ground N allocation of organic soybean was examined in two experiments conducted in Eastern Austria. During early development, individual soybean plants were labelled with a 15N-enriched urea solution by the petiole-feeding method. The 15N enrichment of these plants and surrounding soil relative to their natural 15N abundance was determined at plant maturity. The proportion of soil N derived from roots was calculated from root and soil N isotope data. Total below ground plant N, including rhizodeposits, amounted to between 6 to 48 % of total plant N. The proportion of total plant N allocated below ground was inversely related to shoot N content. Tipo: Conference paper, poster, etc. Palavras-chave: "Organics" in general; Crop husbandry.
