Forage legumes have high potential degradability, indicating that they might need to stay in the rumen for a longer time (MolinaAlcaide et al., 1996) to increase microbial protein yield. Microbial protein contributes about two thirds of the amino acids absorbed by ruminants (Pathak 2008). Protein supplements which have proper levels of rumen undegradable protein provide growth limiting amino acids like lysine and methionine (Rezai et al., 2012). Nyambati et al. (2003) showed that milk production can be increased by supplementing with velvet bean, highlighting the importance of integrating legumes into the low-input, mixed cropping systems in the tropics. The current …

Phosphorus (P) is a key input necessary for high production in many temperate, grass-legume pasture systems in Australia because the pastures are situated on P-deficient and moderate to highly P-sorbing soils. A consequence of P-sorption in these soils is that much more P must be applied as fertiliser than will be exported in animal products. The P balance efficiency (PBE=100*Pexport/Pinputs) of grazing enterprises (e.g. wool, meat, milk and live animal export) is about 10-30% and compares poorly with some other agricultural enterprises (e.g. 45-54% for grain production; McLaughlin et al. 1992; Weaver and …

Steep, non-arable hill country is a significant feature of New Zealand farming (Sheath 2011) and large tracts of it have been improved by over-sowing grass and assorted clover species, particularly white clover (Trifolium repens L.). Numerous other legume species are available in New Zealand from similar environments overseas that may be more productive on some steep hill country. Plant breeders in New Zealand have also produced inter-specific hybrids (Williams et al. 2010) with potentially useful attributes. As part of a large project to increase pasture production on non-arable hills, a range of legume species were established at 2 …

Combinations of various plant species or functional groups can enhance sward structure, the function and stability of an ecosystem, supplement forage production and mitigate negative environmental impacts. Climatic variation, rising temperatures, changing precipitation and other extreme climatic events may lead to changes in plant diversity (Soussana and Lüscher 2007). At the same time it is very important to optimise functional diversity by combining species with different properties that are well adapted to the local environments (Huyghe et al. 2012). Successful selection and management of legumes influences the herbage production, nutritional quality and sustainability of grazing systems. Therefore, their role …

Past mismanagement, overgrazing, invasive weedy species, wildfires, marginal crop production, mineral and energy extraction, recreation and global climate change are challenges currently facing rangelands (Pierson et al. 2011). These disturbances may lead to long-term reductions in biodiversity, altered nutrient and water cycling, diminished forage production for livestock and wildlife, increased wildfire frequency and increased soil erosion and stream sedimentation (Sheley et al. 2008). Rangeland revegetation with desirable plant materials may be required to improve degraded conditions, speed recovery, and prevent further erosion and degradation. There is a critical need for plant materials to restore and revegetate rangeland ecosystems. …
