The Dryland Pastures Research Group, and On-Farm Research (https://on-farmresearch.co.nz/) are currently contributing to “Regenerating Hill Country Landscapes” theme of the Hill Country Futures programme (https://www.hillcountryfutures.co.nz/). Specifically, we are working on:
- Research Aim 2.1: Modelling forage legume yield nationally (Lucerne proof of concept),
- Research Aim 3.1: Desktop analysis of plants for the landscape and
- Research Aim 3.2: Evaluation of legumes in different environments.
Development of lucerne yield and suitability maps for New Zealand (RA 2.1)
The APSIM Next Generation model was used by the Lincoln based Plant & Food Research and Landcare Research modelling teams to develop a nationwide lucerne yield map. Yield simulations were at 5 km resolution in response to 30 years of historical weather data to determine areas suitable for growing lucerne (Teixeira et al. 2020). Subsequently, annual shoot DM yield were estimated for both rainfed and irrigated soil moisture conditions.
The AgYields National Database (RA 3.1)
A spin-off from this programme has been the development of the AgYields National Database, which is a national repository of crop and pasture yield data collected by staff, students and researchers at universities, crown research institutes, industry organisations and commercial businesses throughout New Zealand.
This open access database provides long-term storage and security for pasture and crop growth data, which would otherwise be lost over time. Researchers are encouraged to deposit their data by creating an account here: https://www.agyields.co.nz/home
Further information can be found here: https://www.hillcountryfutures.co.nz/resources/beef-and-lamb-knowledge-hub
Legumes in different environments (RA 3.2)
For Research Aim 3.1 the DPR Group is also working with On-Farm Research in the North Island to collect and collate yield and quality data for a range of pasture species and mixtures throughout New Zealand. In addition, we are collecting a range of on-site data to quantify the environment at the sites.
