چکیده انگلیسی:
PastureBase Ireland (PBI) is a web-based grassland management application incorporating a dual func
tion of grassland decision support and a centralized national database to collate commercial farm grass
land data. This database facilitates the collection and storage of vast quantities of grassland data from
grassland farmers. The database spans across ruminant grassland enterprises – dairy, beef and sheep.
To help farmers determine appropriate actions around grassland management, we have developed this
data informed decision support tool to function at the paddock level. Individual farmers enter data
through the completion of regular pasture cover estimations across the farm, allowing the performance
of individual paddocks to be evaluated within and across years. To evaluate the PBI system, we compared
actual pasture cut experimental data (Etesia cuts) to PBI calculated outputs. We examined three compar
isons, comparing PBI outputs to actual pasture cut data, for individual DM yields at defoliation
(Comparison 1), for cumulative annual DM yields including silage data (Comparison 2) and, for cumulative
annual DM yields excluding silage data (Comparison 3). We found an acceptable accuracy between PBI
outputs and pasture cut data when statistically analyzed using relative prediction error and concordance
correlation coefficients for the measurement of total annual DM yield (Comparison 2), with a relative pre
diction error of 15.4% and a concordance correlation coefficient of 0.85. We demonstrated an application
of the PBI system through analysis of commercial farm data across two years (2014–2015) for 75 com
mercial farms who actively use the system. The analysis showed there was a significant increase in
DM yield from 2014 to 2015. The results indicated a greater variation in pasture growth across paddocks
within farms than across farms.
