Última Comparison of Decision Rules for Subsurface Drip Irrigation Practices Using a Nonlinear Mathematical Programming Model AgEcon Salim, Juma K.; Dillon, Carl R.; Saghaian, Sayed H.; Kanakasabai, Murali. A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

Ano: 2005 URL: http://purl.umn.edu/35517 Precision Feeding in Dairy Ration Cost Minimization Under Producer's Risk Management AgEcon Salim, Juma K.; Dillon, Carl R.. The biophysical simulation data from Cornell Net Carbohydrate and Protein System were used in non-linear programming model for least cost ration incorporating ingredient nutrient and price variations. Precision feeding practice indicated to have lower mean cost ration than whole herd feeding in terms of ration cost.

Ano: 2007 URL: http://purl.umn.edu/34925 An Integrated Precision Production and Environmental Management Analysis of a Kentucky Dairy Farm AgEcon Salim, Juma K.; Dillon, Carl R.; McAllister, Jack; Hancock, Dennis. This study compares and contrasts the profitability of different dairy management practices through precision livestock farming. Feed analysis and crop yields were simulated. The proposed alternative feeding program demonstrated less manure and nutrient excretions. When mathematical programming model was employed, uniform rate application manifested the highest selected economic values.

Ano: 2005 URL: http://purl.umn.edu/19407 Risk management on application of minimum-cost feed ration for nitrogen and phosphorus reduction on dairy farm AgEcon Salim, Juma K.; Dillon, Carl R.; McAllister, Jack. The traditional mathematical programming model with the objective function of feed ration cost minimization is used to accommodate risk management responses to price variability associated with feeding a particular feed ration over time. The model incorporated biophysical simulation data using Cornell Net Carbohydrate and Protein System (CNCPS) software in addressing nutrient requirements and excretions. In addition, it used historic feedstuff prices in a mean-variance (E-V) framework analysis. The optimized seasonal feeding indicated to have a lower mean ration cost and lowest nutrient loading followed by optimized uniform feeding program. The feed cost optimization proved to be a better strategy in minimizing ration cost and reducing excretions both... Tipo: Conference Paper or Presentation Palavras-chave: Risk and Uncertainty. Ano: 2006 URL: http://purl.umn.edu/21274 Profitability of Dairy Cattle Through Precision Livestock Farming Management Practices AgEcon Salim, Juma K.; Dillon, Carl R.; Saghaian, Sayed H.; McAllister, Jack; Amaral-Phillips, Donna M.. The purpose of this study is to compare and contrast the profitability of different dairy management practices through precision livestock farming. Feed analysis and crop yields were simulated. Mathematical model was used for profit maximization. The results indicated that the proposed modification had a higher profit than the base plan.
