The goal of this research was to develop spatial regression methods to economically evaluate on-farm site-specific management (SSM) trials. Whether yields are collected with a combine yield monitor, a weigh wagon, or other technology, they usually have a spatial structure. Covariates including...

Due to a rapid yield decline, plantain fields in Southeastern Nigeria are reverted to fallow after two years. However, population pressure leads to shorter fallow periods and high rates of deforestation. This study investigates the potential of mulch-based systems for perennial plantain...

This paper provides a critical review of the literature on non-market valuation methods to estimate the welfare impact of novel products; it is the first study to assess both observed data- and perception-based methods as non-market valuation methods. Observed databased methods include budgets,...

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...

This analysis used simulation to compare the cost of intergenerational transfer of farm estates under the pre-1981 tax rules and the Economic Recovery Tax Act of 1981 (ERTA) provisions. ERTA reduces transfer costs for almost all the estates considered. Large estimates tend to benefit more than...

Initial ideas on risk management uses of precision agricultural technology focused on site-specific treatment of problem areas to reduce the probability of low yields and returns. Recent discussions deal with sensor and remote-sensing information to improve marketing and "as applied maps" as...

The net impact of pest-resistant GM crops on the welfare of both producers and consumers in developing countries is currently unknown and subject to speculation. This study uses choice-based conjoint protocol to estimate the net impact of pest-resistant Genetically Modified (GM) cowpea on net...

Understanding the relationship between soil fertility dynamics and crop response is conceptually appealing. Even more appealing is comprehension of the spatial and temporal heterogeneity of these connections over a production surface and across seasons. Knowledge of these interactions is...

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...
