Dual-purpose winter wheat (fall-winter forage plus grain) production is an important economic enterprise in the southern Great Plains. Grazing termination to enable grain production is a critical decision. The objective is to determine the optimal grazing termination date for dual-purpose wheat....

The study reported in this paper measures differences in profitability between conservation farming (CF) practices and conventional agriculture by comparing the value of differential output with the differential input costs. The main objective is to address and fill several important knowledge...

This study estimates the farm-gate breakeven price of switchgrass relative to wheat in Oklahoma. The breakeven price of switchgrass is determined for two situations: when external consequences are ignored and when the environment costs of changes in soil erosion, fertilizer (nitrogen and...

Biorefineries that plan to use switchgrass exclusively will have to account for year-to-year variability in feedstock production. The objective of this research is to determine the quantity, class, and location of land to lease for switchgrass production to provide for the needs of a...

This study was conducted to determine the value of independent and joint nitrogen and phosphorus soil tests. Generalized stochastic dominance was used to estimate the value of information. Combined information from both the nitrogen and phosphorus tests was substantially more valuable than the...

Historically, the vast majority of cropland in the western Great Plains was either seeded to continuous monoculture wheat or was in a wheat-fallow rotation. The objective of this paper is to determine the combined effects of crop diversity and tillage systems on wheat grain yield and net returns...

Historically, cropland rental rates have been substantially higher than rental rates for pasture. Currently however, the gap between selling prices of cropland and pasture in Oklahoma has shrunk in western Oklahoma and pasture now sells for more than cropland in eastern Oklahoma. Regression...
