This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines. Users of the model may simulate any feasible...

This report describes four models used to analyse Australian broadacre mixed-grain farm systems. The models that are included in this report are: IMAGINE, STEP, LUSO and APSfarm. For each model, we include a brief description of how they work, their data requirements and model outputs. IMAGINE...

The potential for computer-based decision support tools (DSTs) to better inform farm management decisions is well-recognised. However, despite considerable investment in a wide range of tools, the uptake by advisers and farmers remains low. Greater understanding of the demand and the most valued...

Implications of increasing labour cost and development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated. The study employs RIMPhil (Resistance and Integrated Management in the Philippines), a bioeconomic simulation model developed to...

This paper has been published in a peer-reviewed journal as: Kragt, M.E., Pannell, D.J., Robertson, M.J. & Thamo, T. (2012) Assessing costs of soil carbon sequestration by crop-livestock farmers in Western Australia, Agricultural Systems, 112: 27-37. DOI: 10.1016/j.agsy.2012.06.005

The farm-level economics of conservation agriculture (zero tillage, mulching and crop rotation)are described, reviewed and modelled. The economics are defined broadly to include not just shortterm financial benefits and costs, but also the whole-farm management context, constraints on key...

We use nonparametric production function methods to decompose farm-level labor productivity growth into components attributable to efficiency change, technical change, and factor intensity. The estimation is accomplished using balanced panel data drawn from the Kansas Farm Management Association...

Crop production is the main source of livelihood for households in Northern Ghana. The government is committed to improving crop production and knowledge about the technical efficiency of crop farms is essential in guiding policy decisions. This paper examined the technical efficiency of 189...
