Switchgrass (panicum virgatum L.), a viable option for second-generation renewable fuels, has an extended harvest window with optimal harvest affected by yield, storage losses and nutrient uptake. This research shows that optimal harvest occurs later than maximum yield for Haskell, OK and...

Profit-maximizing nitrogen rates were determined for two bermudagrass hay producers, one who considers nitrate toxicity to cattle and one who does not consider nitrate toxicity. Producing bermudagrass hay with a reduced probability of nitrate toxicity requires a $6.02/ton premium to breakeven...

This paper reviews water quality investments that can increase the environment’s capacity to remove nutrients. The nutrient removal effectiveness, uncertainty, and cost of removing nutrients directly from ambient waters is compared to agricultural nonpoint source reductions in the context of...

This study assesses the economic impact of the Electronic Trade Platform MarketMaker on agricultural producers. Results obtained using contingent valuation techniques indicate that producers are willing to pay $47.02 annually for the services they receive from the platform. Producers’...

Over the past decade, Ukraine has become an important player in the international feed grain market. From 2004/05 to 2012/13 it exported on average 25 percent of the total world barley annually, less than a percent lower than the largest barley exporter in the world - Australia. This research...

This study examined the variance in student ratings of instruction that can be explained by room capacity and enrollment capacity when controlling for class size. Enrollment capacity, room capacity, and class size contributed to the statistical variance in student ratings of teaching...

This paper addresses the issue of profitability of beef production from a systems perspective. The model uses information from biological and economic systems to identify factors affecting profitability of nine beef production systems in the Nebraska Sandhills. The results are further used in...

This paper uses experimental methods to examine how individuals react to a set of voluntary incentives related to the conservation of a resource. The goal was to determine whether conservation over a critical area, such as a deep portion of an aquifer, could be encouraged, and whether...

A supply response model for the highest valued citrus commodities in Florida is specified to analyze the impact of climate change on acreage and yield responses. Preliminary results suggest that temperature has an impact on the acreage and yield responses whereas precipitation did not have any...

A spreadsheet-based tool that tracks cow-calf producer net returns (NR) and greenhouse gas (GHG) emissions was used to determine the impact of calving season for three typical farm sizes and four fertilization strategies in Arkansas. Economic and environmental changes were examined for spring,...
