Effect of modern red clover & nitrogen fertiliser on yield, quality and botanical composition of a hybrid ryegrass sward Open
The advantages to pasture quality and quantity using red clover in New Zealand farm systems is becoming more recognised. The performance of tetraploid hybrid ryegrass, with and without red clover, and with and without nitrogen fertiliser (…

Perceptions, Experiences, and Priorities Supporting Agroecosystem Management Decisions Differ among Agricultural Producers, Consultants, and Researchers Open
The sustainability of agriculture depends as much on the natural resources required for production as it does on the stakeholders that manage those resources. It is thus essential to understand the variables that influence the decision-mak…

Integration of sheep grazing for cover crop termination into market gardens: Agronomic consequences of an ecologically based management strategy Open
Cover crops are suites of non-marketable plants grown to improve soil tilth and reduce erosion. Despite these agronomic benefits, the use of cover crops is often limited because they do not provide a direct source of revenue for producers.…

Phytochemical traits underlie genotypic variation in susceptibility of quaking aspen (<i>Populus tremuloides</i>) to browsing by a keystone forest ungulate Open
Summary Overbrowsing by ungulates is a major cause of poor aspen stand regeneration across North America and Eurasia. In general, factors driving ungulate browser preferences include concentrations of plant secondary compounds and the nutr…

Measurement techniques and yield estimates of fodder beet in Canterbury and Southland Open
A survey of commercial fodder beet crops across Canterbury and Southland was undertaken to determine average yields and to provide some basic information on commercial crops. Commercial yields were approximately 19 t DM/ha but higher yield…

Impact of integrated sheep grazing for cover crop termination on weed and ground beetle (Coleoptera:Carabidae) communities Open
Aim:
\nTo investigate how ecosystem water-use efficiency (WUE) varies spatially under different climate conditions, and how spatial variations in WUE differ from those of transpiration-based water-use efficiency (WUEt) and transpiration-ba…
