Abstract:Tedera is a forage legume that can provide out-of-season green feed in Mediterranean climates. To date, growers have had no comprehensive soil nutrition guidelines to optimise tedera production. We undertook field and glasshouse studies to understand tedera’s macronutrient requirements. Three field experiments were sown with tedera cv. Lanza® at Cunderdin, Dandaragan and Three Springs in Western Australia. These experiments evaluated seven levels of phosphorus (P) (0–30 kg ha−1) and potassium (K) (0–80 kg ha−1… Show more
“…The analysis of leaf nutrients content suggests that competition for nutrients was not the reason limiting the development of LANZA ® because the only significant differences were the higher N and S content of plants under competition. The content values of K, P and S were similar to values reported in previous studies for LANZA ® [26]. The higher N and S content could be related to a dilution effect due to the higher biomass of the control plants.…”

“…The differences in leaf nutrients in P, Mg and S were in relation to the differences in concentration of these nutrients in both soils. The P, K and S leaf content was above the critical shoot nutrient concentration at which LANZA ® reached 90% of the peak biomass in Real et al [26] in both soils with no symptoms of deficiency or toxicity for these or the rest of the nutrients analysed.…”

Bituminaria bituminosa var. albomarginata, known as Tedera, is a promising forage for Mediterranean climates. An improved variety named LANZA® has been developed. Previous research suggests that soil water saturation in heavy-textured soils might affect its initial development. Competition from grasses could also compromise its successful establishment and persistence. We investigated the effects of soils with contrasting textures (loamy sand vs. clay) with a high soil water content and the competition from Lolium multiflorum on the development of LANZA® in a pot experiment. Dry mass (DM) production of LANZA® was strongly reduced (86%) when grown with L. multiflorum. LANZA® shoot DM was 60% higher than the total shoot DM production of the mixture of LANZA® and L. multiflorum. Soil type did not significantly affect the shoot and total root DM. However, a 44% reduction of the DM of thin roots and slower development was observed in clay soils, which may indicate a preference for light-textured soils. This study provides further information on the factors limiting the establishment and persistence of LANZA®. Future research should confirm these results at field scale and investigate measures aimed at reducing early competition in monocultures and functional complementarity with partner species in mixtures to successfully establish LANZA®.
