The role of Extension in assisting farmers conducting on-farm trials with yield monitors was assessed by direct casual observation and a formal interview during a three-year case study. Results indicate that Extension has a role in assisting farmers when selecting treatments to test, designing...

Site-specific data is spatially variable, precluding traditional econometric analysis. Some field-scale experimental designs present logistical, operational and mathematical problems in estimating treatment differences, specifically when adjacent observations are of different treatments such as...
