The specifications for this study were set by the need for researchers in the Sustainable Grazing Systems (SGS) Program to have a consistent framework to evaluate experimental results across research sites and to share those results in a comprehensive way with livestock producers, allowing them to consider the full range of outcomes and impacts. To achieve this, the framework needed to account for production, economic and natural resource impacts, and other issues associated with making changes on farms. It also had to be easily applied, and readily understood by all segments of the SGS Program. This approach demanded some elements of pragmatism. Economic analysis of production data was based around net cash flow analysis. Spreadsheet programs were written for beef, self-replacing Merino and prime lamb enterprises. These incorporated the capacity to graph results automatically, provide sensitivity analysis tables, and project net cash flow results averaged over a 10-year period. Net cash flows were given for 2 levels of management skills — 'district average' and 'high'. Placing dollar values or costs on resource impacts was not as simple and could not be achieved within the practical framework required. A qualitative approach to the evaluation of resource impacts was developed in collaboration with researchers, advisors and collaborating producers. A framework was constructed which allows the likely on- and off-farm impacts of any experimental treatments to be identified and subjectively rated for likely importance.A practical tool for integrating and reporting the production and resource impact information was constructed. This captures the net cash flow, the key production data, the off-farm and on-farm impacts and provides an overview assessment of the treatment in a simple table. It provides producers with sufficient information to allow an assessment as to whether adoption of any 'treatment' could improve the profitability and sustainability of their grazing system. This tool was tested across all treatments at the SGS National Experiment sites and found to work well. Examples are presented, covering a range of resource impact and net cash flow combinations.

Hybrid Maize

Need  for corn is increasing, both for food, animal feed, and industrial raw materials. This is an opportunity as well as a challenge for the government in increasing corn production towards sustainable self-sufficiency. Superior varieties are one of the components that can significantly increase yield. Hybrid varieties have a higher yield potential than composites so that the use of hybrid corn seeds can increase the yield of corn per crop area. The Agricultural Research and Development Agency (Balitbangtan) has produced hybrid maize varieties with high yield potential, which are no less competitive with other private hybrid maize, but they are not well disseminated. In order to obtain added value for farmers and the development of Balitbangtan corn seeds, NASA 29's hybrid corn seed propagation was carried out at the farmer level. The study was carried out in Salukayu Village, Papalang District, Mamuju Regency in 2018 covering an area of ​​1 ha. The results showed that corn seeds were 1.5 tons / ha. The Nasa 29 hybrid maize seed propagation farm is economically feasible and profitable, as indicated by the R / C value of 2.35, TIP 637 kg / ha, TIH Rp. 10,623, - / kg and IK Rp. 88,985, / day. The study of the propagation of the NASA 29 hybrid maize seed was financially feasible and the economic benefits were high and efficient.

Technology Dissemination

A review on the community based maize seed production and technology dissemination in Nepal was made in 2009 to know the seed production situation and technology dissemination approaches. Twenty three open pollinated maize varieties and one hybrid were released by the Nepal Agricultural Research Council (NARC) up to 2009. A number of stakeholders were involved on improved technologies dissemination, seed production and marketing. Approaches for technology dissemination include district seed self sufficiency program (DISSPRO) and community based seed production (CBSP) program. About 4500 ton of cereal seeds annually has been producing from these approaches. Approach include subsidies on source seeds, creation of revolving funds, group/co-operative formation, their mobilization for participatory varietal selection (PVS), demonstrations, training, informal research and development (IRD) kit distribution and exchange visits. In community level, activities such as community based seed production approaches, particiapatory technology development, verification and dissemination for sustainable seed production and marketing has been taken place.

AbstractThe public agricultural research and extension system has provided the foundation for great improvements in U.S. agricultural production. However, our incomparable productivity has brought with it serious problems. These problems have also led to a rapidly changing perception about both agricultural scientists and today's conventional agriculture. Critics are placing high on the agenda of the agricultural research and extension establishment the need for alternative technologies that are more sustainable and less exploitative of our resources. The growing demand for alternative systems offers challenges for every part of the establishment-research and extension administrators, branch station/research center directors, and faculty. These challenges and how they should be met are discussed. Alternative systems will become the conventional agriculture of tomorrow.
