A Yield Sensitivity Analysis of Conventional and Alternative Whole-Farm Budgets for a Typical Northeast Kansas Farm
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Diebel,   Penelope L.; Llewelyn,   Richard V.; Williams,   Jeffery R.
This analysis compares net returns of conventional and alternative agricultural cropping systems in northeast Kansas, with and without government commodity programs. The highest net return is consistently from the alternative system, wheat/clover-sorghum-soybeans. Sensitivity analysis reveals that the economic performances of the alternative systems are sensitive to yield penalties.

A Risk Analysis of Converting CRP Acres to a Wheat-Sorghum-Fallow Rotation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Williams,   Jeffery R.; Llewelyn,   Richard V.; Pendell,   Dustin L.; Schlegel,   Alan J.; Troy,   Dumler.
This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region.  This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums.  Yields, input rates, and field operations from an experimental field in western Kansas are used to calculate net returns for each tillage strategy.  Although current net returns to crop production using reduced tillage and no-tillage strategies are higher than CRP, risk analysis indicates CRP...

Net Returns for Grain Sorghum and Corn under Alternative Irrigation Systems in Western Kansas
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Williams,   Jeffery R.; Llewelyn,   Richard V.; Reed,   Matthew S.; Lamm,   Freddie R.; DeLano,   Daniel R.
This study evaluates seven irrigation systems for use in production of grain sorghum and corn. These systems are medium pressure center-pivot (MPCP), low pressure center-pivot (LPCP), low drift nozzle center-pivot (LDN) , low energy precision application center-pivot (LEPA), furrow flood (FF) , surge flood (SF), and subsurface drip (SD). After-tax net present value estimates from investing in and using each system over a 10-year period to produce grain sorghum and corn are compared. The surge flood system, has the highest net returns under typical conditions for irrigation of both grain sorghum and corn. The furrow flood system generates the next highest net returns for both crops, followed by the subsurface drip system. The medium pressure center-pivot...
