This study examines the impact of adopting Bt corn on farm profits, yields, and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity. The model is estimated using nationwide farm-level survey data for 2005. Regression analysis confirms that Bt adoption is associated with increased variable profits, yields, and seed demand. However, the results of this analysis suggest that Bt adoption is not significantly related to insecticide use. This result may be due to the fact that insect infestation levels were lower in 2005 than they were in previous years.

Aligning the production of lamb cuts with consumer preferences is an ongoing challenge for the Australian lamb supply chain. In recent decades, genetic and on-farm management practices have improved, while the demographics of consumers and their consumption patterns have changed. This has resulted in larger traditional lamb cuts, which have less appeal to modern consumers. Therefore, research has been conducted to determine the potential to fabricate new value-added lamb cuts from heavier carcasses, determine consumer preferences for lamb roasts, investigate the impact of increasing carcass weight and fat depths on the production of value-added retail cuts and determine the nutritional composition of these cuts. In an effort to address these issues, a new value-added cut, the compact shoulder roast, was developed from the forequarter of the carcass to provide an option for retailers processing heavier lamb carcasses. A subsequent survey of consumer preferences highlighted that preferences for roast weight and size were affected by frequency of consumption, with daily consumers preferring the heaviest roasts and younger consumers preferring lighter roasts, implying the need for further fabrication, such as that required for the compact shoulder roast. However, the time taken to fabricate these value-added cuts increases with each kilo increase in carcass weight and decreasing saleable meat yield of lamb carcasses results as the degree of value-adding increases, indicating that a higher average price per kilo is required at retail. Subsequently, value-added cuts will need to be marketed on the basis of other product qualities such as nutritive value. However, profiling of lamb cuts has also shown that there is little data on the nutritive value of a range of lamb cuts, apart from the loin, so work has been undertaken to address this deficiency using grass-fed lamb through a major supply chain.

On-farm studies provide a realistic setting to examine the impact of interactions of management practices on weed communities within various farming systems. Clustering farm units into groups that use similar management practices enables the replication of farm management systems within on-farm studies. The goal of this study is to objectively classify farm units into management systems on the basis of quantitative variables describing aspects of cropping history and chemical input levels using multivariate techniques. Twenty-eight Saskatchewan farmers provided details of their management practices from 1990 to 1997 through a series of questionnaires. Twelve variables derived from the questionnaires were used to describe cropping history, pesticide, tillage and fertilizer use on each farm unit. These variables were used to cluster farm units using minimum variance classification and NMS ordination. Both techniques identified seven farm management systems. The greatest differences were observed between organic and non-organic systems. Farm management systems that used annual fallow and continuous annual cropping histories were most similar. The consistent results obtained by use of the two unrelated methodologies indicate the utility of this approach for the classification of farm management systems. Key words: Farm management system, classification, cropping history, chemical input level, on-farm

Dairy Systems Monitoring (DSM) was developed out of response from dairy farmers for a benchmarking tool that made fair and equitable comparisons between farms. This benchmarking system is used by the clients to improve their productivity and profitability. The dairy farm simulation model UDDER is used to simulate the farm system. The input information is milk production from fencepost, and monthly data from the farm, including, areas, stock numbers, supplements, crops and nitrogen (N). The model is then calibrated to simulate the farms production, revised and validated monthly. There has been a successful uptake of this program. Currently 50 farms are involved. Dairy Systems Monitoring has generated change in the systems of participating farmers. Dairy Systems Monitoring has proven to be an effective tool to demonstrate the impact of a range of new technologies on farm systems. The tool is used on an ongoing basis to simulate and compare different operating strategies. It has the ability for clients to compare themselves to simular farms. A key benchmark that is analysed is the feed harvested. For every additional 1 tonne of dry matter (DM) harvested, the gross margin (GM) increases by $339/ha. The question this poses for participants is "how do we harvest more pasture"? Is it by growing more pasture, or improving management to harvest more of the existing pasture growth? Dairy Systems Monitoring is an effective extension tool to highlight the impact of new technologies or management practices on the client's farm program. Keywords: benchmarking, dairy farm programmes, feed harvested, gross margins, UDDER model
