A survey of the pasture productivity settings, practices and attitudes was undertaken for 229 pastoral producers who volunteered to enter the Triple P Program in 1997, and for 89 pastoral producers from 2 representative districts of Victoria. The latter group of producers was considered to be representative of the general population of pastoral producers in the regions where the Triple P Program was undertaken. Comparison of the survey results reveals that the volunteer participants entering the paired-paddock extension program employed different management practices and had different attitudes to productivity issues compared with the general pastoral producers. Before entering the program the Triple P volunteers were already employing more productive practices such as soil testing, measuring pasture availability and spring lambing. In addition the volunteers had higher whole-farm stocking rates and fertiliser use than the general pastoral producers. The different management practices employed by the 2 groups were consistent with their contrasting attitudes towards managing their farms. The Triple P volunteers were focussed on improving production per hectare through increased stocking rates, which could be achieved by additional expenditure on fertiliser and pasture renovation. The general pastoral producers were more focussed on improving production per head which was achieved by gauging animal performance, maintaining stock in good condition and maintaining expenditure on animal health. We contend that the differences identified between the producers volunteering to participate in the Triple P Program and the general pastoral producers are a direct consequence of the voluntary approach used to recruit Triple P participants. This approach attracts a select group of farmers who are inclined to engage in extension and training activities and tend to have different attitudes and practices to the general pastoral producer. A more proactive approach to recruitment will be required if a larger proportion of the general producer population is to engage in the paired-paddock extension program.

A checklist was developed to determine the extent to which different adult learning principles were embodied in the paired-paddock model used in the Triple P Program. A total of 181 producers that were involved in the Triple P Program between 1997 and 1999 completed the checklist at the end of the program. This enabled the relative strengths and weaknesses of the paired-paddock model from an adult learning perspective to be identified. The 15 adult learning principles assessed in the checklist were all operating in the paired-paddock model to varying degrees. The adult learning principles relating to the learning environment and learning process received the highest ratings from producers. In addition, the ratings given for these adult learning experiences were significantly correlated with the change index, a measure of the degree of on-farm adoption of productive pastures by the program participants. The principles relating to the learning environment were the existence of a comfortable learning environment, which allowed effective 2-way communication enabling participants to learn from each other. Principles relating to the learning process were the active participation of producers in activities, the use of knowledge and experience within the group, and the provision of opportunity for reinforcement of information and practice of skills. The relative weaknesses identified in the paired-paddock model from an adult learning perspective were the degree of self-directed learning done by participants, the limited involvement of participants in planning their learning experience, and the limited extent to which the program related to problem issues among the group. Despite these relative weaknesses it was concluded that the paired-paddock model embodies sound adult learning principles that assist in the delivery of quality learning outcomes for participants.

A detailed study was undertaken on the pasture management practices of 146 producers across south-east Australia who participated in the Grassland’s Productivity Program (GPP) for 3 years between 1993 and 1997. The GPP was an extension program to assist wool producers to develop skills and gain confidence in their ability to manage more productive pastures on their farms. The program consisted of 50 farmer groups (200 farmers participating) spread across the 4 states of South Australia, southern New South Wales, Victoria and Tasmania. Each farmer established paired-paddocks on their own property to compare productive pastures with existing pastures. Productive pastures involve increased rates of fertiliser on pastures containing productive species, with stocking rate adjusted to consume available pasture. After 3 years of involvement in the GPP, there was a whole-farm increase in P fertiliser use by 6.3 kg P/ha, stocking rates by 2.6 dse/ha and annual pasture resowing by 0.9% of the farm, when averaged across the 146 participants. The participants were applying the productive pasture technology to almost a third of their properties in 1997 and the intention was to increase this to over half of their properties by 2000. The participants also changed farm management practices as the program effectively developed management skills. There were increases in the ability to assess pasture quality and quantity, livestock by weighing or physical assessment, and the ability to calculate per hectare production and per hectare gross margins. A high proportion of GPP participants were soil testing (0.92) and spring lambing (0.72) at the completion of the program. The results indicated that the adoption of productive pastures was generally consistent across south-east Australia for pastoral producers who participated in this program, although south-west Victorian and south-east South Australian GPP participants did increase whole-farm P application by more than GPP participants from outside that region. The widespread change in farming practice was attributed to the additive and interactive effect of the paired-paddock comparison, the guidance provided by the facilitator, the group interaction and the skills training. Each of these components of the paired-paddock model combined to form an effective agent for change to increase pasture productivity on these grazing properties.

A survey of 146 pastoral producers across south-eastern Australia was conducted after they had participated for 3 years in the Grassland’s Productivity Program. The exit survey, together with earlier surveys, enabled the changes in whole-farm stocking rate and phosphorus fertiliser use, management practices, and perceptions of the Grassland’s Productivity Program, to be determined. The magnitude of the increases in productivity settings and the increased use of most recommended management practices were not influenced by either the facilitator who guided the groups of participants, or by the annual rainfall for the farm, which varied between 400 and 1000 mm. Path analysis of the survey data found that changes in productivity settings during 1993–97 did not depend on any one feature of the extension program. Rather the changes resulted from a hierarchy of interacting effects including certain initial (1993) and final (1997) management practices, attitudes to the program and perceived benefits from the program, and situational constraints such as the availability of suitable soil types on the farm. There were differences in the significant terms in the regression models that predicted the change in stocking rate, the change in fertiliser rate, or the combined variable for both, that was designated as the change index.

Summary. Nineteen participants in the Grassland’s Productivity Program were surveyed in autumn 1997 to determine whether they had continued to adopt productive pasture practices during the final 18 months of the program. The objective was to determine whether changes in commodity prices in 1996, involving falls in wool and beef prices and increases in prime lamb prices, and unfavourable seasonal conditions, impacted on the continuing adoption of productive pastures by participants of the Grassland’s Productivity Program. Despite the less favourable market and seasonal conditions, the Grassland’s Productivity Program participants continued to increase their adoption of productive pastures, almost trebling the area of land under the productive pasture technology from mid 1995 to 1997. This was achieved by rationalising farm expenditure in ways to cope with the less favourable conditions. The first was to undertake more pasture manipulation instead of high-cost pasture renovation. The second was to maintain expenditure on phosphorus fertiliser but focusing the application on more productive pasture paddocks. As a result the stocking rate across the whole farm was only increased marginally (by 0.2 dse/ha) from 1995 to 1997. Nevertheless the participants predicted that they would increase their stocking rate by an average of 17% across their farms, from 10.9 to 12.7 dse/ha, by the year 2000. The continuing strong commitment to adopt productive pastures is highlighted by the future intention of over half of the Grassland’s Productivity Program participants (53%) to implement the technology over their whole farm. The remaining participants intended to have at least half their farm under productive pastures. There was no discernible difference between wool growers and prime lamb producers in achieving adoption intentions apart from the area of the farm that is sown to productive species. This indicates that a short-term change in enterprise profitability is not necessarily a major determinant of adoption of more intensive grazing practices by participants in this type of group-facilitated program.

Summary. A detailed survey was undertaken in the spring of 1995 with 20 wool producers in south-west Victoria and the south-east of South Australia to determine the impact of their participation for 18 months in a program called the Grassland’s Productivity Program. This program involved groups of producers establishing paired-paddock comparisons on their own farms with guidance from an experienced facilitator. Productive pasture practices (increased fertiliser rates, responsive pasture species and high stocking rates) were used in one paddock, while the remaining paddock was managed with existing practices. A second group of 15 producers from the same districts who did not participate in the Grassland’s Productivity Program were selected at random and also surveyed. Although the 2 groups of producers had similar pasture productivity parameters (phosphorus fertiliser, stocking rates and pasture resowing rates) in the autumn of 1993, the Grassland’s Productivity Program participants had significantly (P
