| Potassium (K) and phosphorus (P) application to sunflower (Helianthus annus L.) reduced cost of production, increased seed oil and protein concentration, yield and net returns on the K and P deficient soils in Northwest Pakistan. Field experiment was conducted at the New Developmental Research Farm of NWFP (North West Frontier Province) Agricultural University Peshawar, Pakistan during summer 2006. The experiment was carried out in a randomized complete block design with split plot arrangements using three replications. Six levels of K (0, 25, 50, 75, 100 and 125 kg ha-1) were kept in main plots while four levels of P (0, 45, 90 and 135 kg ha-1) were kept in sub-plots. Increase in K and P levels enhanced seed oil concentration, on the other hand, increase... |

| The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities. |

| A brief review of the beef and cattle market following the diagnosis of Bovine Spongiform Encephalopathy (BSE) in Canada and U.S. in 2003 is conducted. The focus is on the recent changes in the beef market experienced by major exporting and importing countries with special emphasis on the beef trade and cattle industry in the U.S. A single case of BSE in the U.S. has significantly disrupted global beef trade. Many countries banned beef imports from the U.S. and Canada. Continuation of these bans through 2004, particularly for the U.S., resulted in reduced beef exports. Brazil has become the number one beef exporter with estimated exports of 1.47 million tons in 2004 and is forecast to export 1.62 million tons in 2005. U.S. is the largest beef... |

| Beef cattle enterprises for the 91% of Texas producers with less than 100 cows represent secondary or supplemental enterprises. In most cases the operator is depending on surplus or discretional labor and the alternate use of the physical resources is limited due to topography or environmental factors. These characteristics transform the decision making process from a variable resource allocation problem to a fixed resource problem. Monthly average prices for 300-900 lb stocker steers, divided into 50 lb intervals, are analyzed for three market locations for the period 1992-1999. Consistent price roll back is observed as the price per cwt decreases as the weight increases. However, as the reduction in price is more than offset by the increase in value due... |

| Production data provided by commercial producers of grain sorghum is used to estimate response functions for three alternative management decision models. The evaluation of yield to the total water availability, irrigation, and water application as a percent of potential evapotranspiration. The three methods provide similar results, but each provides unique information and adds valuable information to the decision process. The value product functions and the energy cost function are used to determine the profit maximizing level of water application where adequate water to fully meet the crop needs is available and to determine the irrigation vs. no irrigation decision where water availability is limiting. |
