P1a – From A to B (A2B): improving Kikuyu’s productivity through remote sensing and data-based management

Dairy UP’s 10 projects collectively address on-farm productivity, de-risking the industry and developing new markets.

Seeking DNA donations

As part of the Dairy UP subprogram P1c, we are conducting a DNA survey of kikuyu pastures across southeastern Australia. The purpose of the study is to the evaluate kikuyu varietal diversity across the landscape.

New Kikuyu varieties identified

Three new Kikuyu lines have been identified by Project P1c for further screening. This will involve larger plot trials at more locations in 2024.

We aim to unlock the true potential of kikuyu-based pastures by exploring new management options using advanced technologies and monitoring systems.

This project will close the gap on practical constraints and impediments facing commercial farms using or with the potential to use kikuyu relating to:

 

  1. The difficulties in managing and utilising pasture within a whole farm system, with growth rates varying from <40-50 kg DM/ha in winter (annual ryegrass) and approaching 200 kg in good conditions in summer (kikuyu). This, coupled with lack of real time and systematic monitoring of pasture growth rate, almost inevitably results in summer surpluses that can only be potentially utilised by ensiling. However, kikuyu losses quality very rapidly as biomass increases, so making silage of a moderate/reasonable nutritive value is very challenging. Managing ‘effective’ stocking rate during the summer is key for success.

 

  1. The inter- and intra-annual variability in growth rates, particularly in dryland systems. This has similar consequences as point #1 (i.e. large variation in growth rate that limits farmers’ ability to utilise pasture better); again, its impact exacerbated by the lack of adequate automated monitoring systems of pasture growth.

June 2023
Analysis of the first year’s data has shown that satellite imagery alone is not accurate enough to make management decisions for Kikuyu pastures with confidence. Despite this, the decision support tool was seen by farmers as a smart platform to follow farm management and to coordinate activities with the staff. Read more
